This is while AIT specialists’ wages have fallen by the same period.

Payments for programming skills such as Java (Java) and PHP (PHP) are on the rise. The salary announced in the field of technology for the third consecutive year in 2018 has increased to 7.1%.

Also, with the continued increase in demand for Java developers, PHP and NET (.NET.), Payments to technology experts have been increasing significantly.

During this three-year period, Java developers’ wages have experienced the greatest jump, up 41 percent, and their wages have risen by 6 percent since the start of the year.

The average Java developer has a budget of 63, 700 pounds, which can be increased to 70, 700 pounds depending on the employment data published in Reed.

The second-highest-paid, full-stack developer business (this title is in the field of software development and development, refers to a programmer who has full knowledge of a particular field and tools).

The average payment for this job is 53, 500, 60, 300 pounds. The wage growth of these programmers in the past year and 2016 was 6.6% and 18.8%, respectively.

PHP developers experienced the most wage increase last year. The average wage increase for the last three years was about 20.6%.

The developers also experienced widespread wage increases over the course of the course. The wages of these programmers reached £ 39,900 in 2016, up 18.8% to £ 47,400 this year.

In most directories, JavaScript, Java, and Python programming languages ​​are considered to be the most popular programming languages, respectively.

Data scientists, data analysts, industrial architects (digital technical architects) and network engineers and DBAs have also experienced a two-digit increase in their wages over the last three years.

Payments for business-related jobs, such as business analysis and project management, have also increased, but this increase has been lower than that of developers.

In fact, according to data released by Reed, IT specialist, is one of the few jobs that have been falling in wages over the past three years.

On average, AIT specialists’ wages fell from 89, 200 to 83, 600 pounds.

These data, derived from jobs and wages advertised between 2015 and 2017, are redeemed at Reed.

According to Reed’s website, these salary increases are associated with an increase in demand for employees dominant in these skills.

While demand for technology-related jobs in general in the year 2018 has increased by 10%, demand for statistical scientist, 20%, developer of 13%, and developer of Business (Business Intelligence) has increased by 13%, much higher than This is the average amount of this field.

 The demand for full-stack developer has also increased by 41% since the beginning of 2018, given the many skills that these developers should have.

“There are plenty of jobs for experienced mobile applications and front-end developers,” says Andrew Gardner, Reed Technology manager. In addition, companies have experienced cloud computing and storage related skills. have.

As a result of legislation such as the GDPR (European Union Privacy Policy), many requests are created; for example, data-driven jobs are growing; however, companies are sure that they have the right skills, systems and processes. ”

 

Do the reviews of the most popular programming languages provide the right results

آیا شاخص‌های بررسی محبوب‌ترین زبان‌های برنامه نویسی، نتایج درستی ارائه می‌دهند

Are the most popular programming languages ​​selected based on indicators and components? Are the most trusted programming languages ​​the most popular?

Usually, software professionals go to valid TIOBE charts to learn about the most popular programming languages.

Through these charts, they can find out which of the most popular programming languages ​​in the world are.

The valid TIOBE charts and the information provided on the popularity of programming languages ​​in these charts show that Java programming languages ​​and programming languages ​​C, programming languages ​​have become the most popular languages ​​over time, and from time to time.

But wait a moment and do not conclude too fast. The graphs and indicators provided by PYPL, as a competitor to TIOBE charts, show other results.

Based on PYPL charts, Python and Java programming languages ​​are among the most popular programming languages ​​and are essentially the kings of programming languages.

Based on the PYPL charts, the C language, which is incredibly developed with the C ++ programming language, is less popular, and is located in the lower sections of the ranking list of popularity of programming languages.

The question may well be for you: which are the correct results and which charts give you the right information?

بهترین زبان برنامه نویسی 2018

One of the important things to keep in mind is that each of the graphs takes different indexes and components to select the most popular programming languages.

Of course, one common point in the methodology of both graphs is that the performance of both is controversial in measuring the plurality of programming languages.

TIOBE considers search engine quantification as a measure of measurement.

While PYPL is important, the importance of the frequency of searches, and how often they are searched, and takes it into consideration.

We must say that both measurement indicators do not consider good components for measurement. Of course, given the availability of online resources, the amount of searches in search engines can not be considered as one of the important indicators and is considered an old way.

Many millions of web pages may still provide information about a popular but old, perhaps dead, site, as there are many zombie sites (sites that fail to update their content for some reason) or blog posts that have not been read for many years. .

The extent to which content search is considered to be an important indicator of the popularity of a programming language is not a valid criterion.

Programming languages ​​are taught to students in educational environments, and therefore the frequency of searches for educational files is not a valid indicator for evaluation, and can provide very contradictory information.

This measure of scale, in principle, is not a significant indicator of what really can be, the degree of popularity of programming languages ​​out there.

Ultimately, it can not be determined with this information which programming languages ​​are really used by learners of programming languages ​​in practice.

When you pay more attention to numbers, you will also encounter more strange issues. According to the TIOBE charts, the programming language C, in its 5 minutes, has been ranked the “Programming Language Of The Year.”

It seems that the C language has reappeared in latency systems. However, the reason for such results in measurements can be related to incomplete and artificial methods of measurement.

جاوا اسکریپت

The most controversial statistics are related to the Objective-C and Swift programming languages ​​used to write local applications on iOS.

Overall, the recent popularity of programming languages ​​for cross-platform platforms, such as Xamarin and React Native, seems to have declined.

Apple has been leaning towards the use of Swift programming language for about four years, and it seems to be a great programming language.

However, the Objective-C language is still much more popular and used extensively.

When looking at people who deal with iOS / tvOS / watchOS apps or talking to many iOS developers,

we find it unlikely that programming has changed the Objective-C language Swift language.

But all these stories and stories can not be replaced by statistics and data. If we see that popularity indexes have different outcomes with the personal experiences of programmers,

we can conclude that individual biases and individual bias can lead to incorrect results.

Of course, there is another measure of measurement to measure the popularity of programming languages. If you notice the GitHub’s annual report on the 15 popular programming languages ​​on the platform,

you’ll find that the results of this report are very close to the results presented

by the individual experience of market developers,

and it differs from the results from the TIOBE and PYPL charts.

According to GitHub, in 2016 and 2017,

the most popular programming language in the world, with a significant gap from the rest of the languages,

has been Javascript.

Python ranked second,

Java ranked third and Ruby ranked fourth. These results show a dramatic difference compared to the TIOBE chart.

On the TIOBE chart, Java and C are the most popular languages ​​first,

and then with a large gap between Python and C ++, javascript stands at eighth place.

Also, according to the PYPL charts,

the popularity of programming languages ​​has been reported as follows: Python,

java at the beginning of the chart, with a lot of distances, javascript and PHP.

زبان برنامه نویسی

Obviously, the Gitache figures do not represent the whole of this area; the sample size is very large and only applies to open source projects.

But GitHub seems to be the only system that makes Swift more popular than Objective-C.

This makes the results look convincing, but again because of its openness,

the results presented through this system can not be considered definitive.

The statistics provided are very important. Beyond curiosity and entertaining, they provide important information.

While the theme of the popularity of programming languages ​​is not,

in general, a very important topic, but it is not trivial. The study of the popularity of programming languages ​​determines which languages ​​are more relevant.

This is important for those who are willing to follow the programming language,

and as a result, people entering the field of programming language learning can teach a language

that is more popular and can provide a job opportunity for them.

 So when the three different methods offer different results,
the conditions are not very interesting and it looks a bit uncomfortable.

am new Red Hat Enterprise Linux version 7 user/sysadmin/developer. This version made the big number change for RHEL 7/CentOS 7. How can I install LAMP (Linux, Apache, MariaDB, PHP) stack on a RHEL version 7 or CentOS Linux version 7 using CLI or over ssh based session?

 

RHEL 7 has been released and CentOS Linux 7 is on its way with many notable changes. This guide explains how to install LAMP server.

More about LAMP

LAMP is nothing but a software bundle or a platform consisting of Linux operating system, Apache web-server, MySQL database server and PHP (or Perl/Python)scripting language. The LAMP stack is used for building heavy-duty dynamic web sites entirely out of free and open-source software. In this tutorial, I’m going to explain how to Linux, Apache, MySQL/MariaDB (drop in replacement for MySQL), PHP (LAMP) stack On CentOS 7 or RHEL 7.

Assumptions

I’m assuming that you’ve installed basic RHEL 7 or CentOS 7 server. Open the Terminal app and type the following command as root user.

You must be familiar with the yum command

You must know your Server’s IP address. Use the following command to find your server’s ip address for eth0 interface:

ifconfig eth0

OR

ip a show eth0

OR

ip addr list eth0 | awk  /inet /{sub(/\/[0-9]+/,  ,$2); print $2}

OR

ifconfig eth0 | awk  /inet /{print $2}

10.41.143.156

I’m going to use IP address 10.41.143.156 for testing purpose. Feel free to replace this IP address with your actual private or public IP address.

Enough talk, let’s set up LAMP stack.

Step #1: Install Apache on a CentOS 7 / RHEL 7 server

Type the following yum command to install Apache web-server:

sudo yum install httpd

 

Sample outputs:

Loaded plugins: amazon-id, rhui-lb

Enable the httpd service at boot time

To make sure the httpd service start automatically at the boot time, enter:

sudo systemctl enable httpd.service

 

Sample outputs:

ln -s  /usr/lib/systemd/system/httpd.service   /etc/systemd/system/multi-user.target.wants/httpd.service

The following command will disable the httpd service at the boot time:

sudo systemctl disable httpd.service

 

Sample outputs:

rm  /etc/systemd/system/multi-user.target.wants/httpd.service

Start the httpd service on a CentOS/RHEL v7.x

sudo systemctl start httpd.service

 

At this stage, you can point your web-browser to your server’s IP address such as http://10.41.143.156). The following page should display on screen:

Fig.01: Check if Apache is Running on CentOS/RHEL 7 server

Stop the httpd service on a CentOS/RHEL v7.x

sudo systemctl stop httpd.service

Restart the httpd service on a CentOS/RHEL v7.x

sudo systemctl restart httpd.service

Finding the httpd service status on a CentOS/RHEL v7.x

To verify that the httpd service is running, enter:

systemctl is-active httpd.service

 

Sample outputs:

active

Gracefully restart the httpd service on a CentOS/RHEL v7.x

sudo apachectl graceful

Test httpd/Apache configuration file for errors on a CentOS/RHEL v7.x

sudo apachectl configtest

 

Sample outputs:

Syntax OK

httpd service default configuration

Default config file: /etc/httpd/conf/httpd.conf

Configuration files which load modules : /etc/httpd/conf.modules.d/ directory (e.g. PHP)

Select MPMs (Processing Model) as loadable modules [worker, prefork (default)] and event: /etc/httpd/conf.modules.d/00-mpm.conf

Default ports: 80 and 443 (SSL)

Default log files: /var/log/httpd/{access_log,error_log}

Step #2: Install MariaDB on a CentOS 7 / RHEL 7 server

MariaDB An enhanced, drop-in replacement for MySQL server. RHEL/CentOS v7.x shifts from MySQL to MariaDB for its database management system needs. Type the following yum command to install MariaDB server:

sudo yum install mariadb-server mariadb

 

To start mariadb, type:

sudo systemctl start mariadb.service

 

To make sure the mariadb service start automatically at the boot time, enter:

sudo systemctl enable mariadb.service

 

Sample outputs:

ln -s  /usr/lib/systemd/system/mariadb.service   /etc/systemd/system/multi-user.target.wants/mariadb.service

To stop/restart and disable mariadb service use the following commands:

sudo systemctl stop mariadb.service #<– Stop mariadb server

sudo systemctl restart mariadb.service #<– Restart mariadb server

sudo systemctl disable mariadb.service #<– Disable mariadb server

sudo systemctl is-active mariadb.service   #<– Is mariadb server running?

Securing MariaDB

Type the following command:

sudo /usr/bin/mysql_secure_installation

 

Sample outputs:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB

SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

 

In order to log into MariaDB to secure it, we ll need the current

password for the root user.  If you ve just installed MariaDB, and

you haven t set the root password yet, the password will be blank,

so you should just press enter here.

 

Enter current password for root (enter for none): PRESS-ENTER-KEY

OK, successfully used password, moving on…

 

Setting the root password ensures that nobody can log into the MariaDB

root user without the proper authorisation.

 

Set root password? [Y/n] Y

New password: YOUR-NEW-PASSWORD-HERE

Re-enter new password: YOUR-NEW-PASSWORD-HERE

Password updated successfully!

Reloading privilege tables..

… Success!

 

 

By default, a MariaDB installation has an anonymous user, allowing anyone

to log into MariaDB without having to have a user account created for

them.  This is intended only for testing, and to make the installation

go a bit smoother.  You should remove them before moving into a

production environment.

 

Remove anonymous users? [Y/n] Y

… Success!

 

Normally, root should only be allowed to connect from  localhost .  This

ensures that someone cannot guess at the root password from the network.

 

Disallow root login remotely? [Y/n] Y

… Success!

 

By default, MariaDB comes with a database named  test  that anyone can

access.  This is also intended only for testing, and should be removed

before moving into a production environment.

 

Remove test database and access to it? [Y/n] Y

– Dropping test database…

… Success!

– Removing privileges on test database…

… Success!

 

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

 

Reload privilege tables now? [Y/n] Y

… Success!

 

Cleaning up…

 

All done!  If you ve completed all of the above steps, your MariaDB

installation should now be secure.

 

Thanks for using MariaDB!

Test MariaDB installation

Type the following command

mysql -u root -p

 

Sample outputs:

Fig.02: Mariadb test connection on a CentOS / RHEL Linux v7.x

Step #3: Install PHP on a CentOS/RHEL v7.x

To install PHP and modules such as gd/msyql type the following yum command:

sudo yum install php php-mysql php-gd php-pear

 

You must restart the httpd (Apache) service, enter:

sudo systemctl restart httpd.service

 

To search all other php modules, type:

sudo yum search php-

 

Sample outputs:

php-cli.x86_64 : Command-line interface for PHP

php-common.x86_64 : Common files for PHP

php-gd.x86_64 : A module for PHP applications for using the gd graphics library

php-ldap.x86_64 : A module for PHP applications that use LDAP

php-mysql.x86_64 : A module for PHP applications that use MySQL databases

php-odbc.x86_64 : A module for PHP applications that use ODBC databases

php-pdo.x86_64 : A database access abstraction module for PHP applications

php-pear.noarch : PHP Extension and Application Repository framework

php-pecl-memcache.x86_64 : Extension to work with the Memcached caching daemon

php-pgsql.x86_64 : A PostgreSQL database module for PHP

php-process.x86_64 : Modules for PHP script using system process interfaces

php-recode.x86_64 : A module for PHP applications for using the recode library

php-soap.x86_64 : A module for PHP applications that use the SOAP protocol

php-xml.x86_64 : A module for PHP applications which use XML

php-xmlrpc.x86_64 : A module for PHP applications which use the XML-RPC protocol

To find more info about a module type:

sudo yum info php-pgsql

 

To install php module called php-pgsql type:

sudo yum install php-pgsql

Test PHP on your server

Create a file called /var/www/html/test.php as follows:

sudo vi /var/www/html/test.php

 

Append the following code:

<?php

phpinfo(INFO_GENERAL);

?>

Save and close the file. Point your web-browser to your server’s IP address such as http://10.41.143.156/test.php (feel free to replace the 10.41.143.156 with your actual IP address):

http://10.41.143.156/test.php

Sample outputs:

Nginx is one of the robust web server in Linux world. Nginx is a free, open source, high performance HTTP server and reverse proxy, as weell as an IMAP/POP3 proxy server. Now, we are going to install Nginx web server.

First, make sure system is upto date:

$ sudo apt-get update

$ sudo apt-get upgrade

#1 – Download and Install Nginx

The easiest way to download and install Nginx is using apt-get command. Here is the command:

$ sudo apt-get install nginx

 

Fig.01: Download and Install Nginx on Ubuntu Linux

 

Just wait until installation is get done on the system.

#2 – Test Nginx

Once it get done, you can open your browser and type url http://localhost or http://your_ip_address to test it. If everything goes normal, you will see Nginx welcome page:

Fig.02: Welcome nginx page on Ubuntu Linux

MySQL Installation On Ubuntu

MySQL is one of the most powerful database management system in Linux world. Next, we are going to install it with PHP support.

#1 – Install MySQL and PHP support

Type the following command:

$ sudo apt-get install mysql-server php5-mysql

 

Fig.03: Ubuntu Linux Install MySQL to Manage Site Data with PHP

 

During the installation, MySQL will ask you to enter MySQL root password, other wise the installation will not continue. Type the password you want, then press OK to continue the installation.

#2 – Test MySQL

Once mysql installation finished, we can test it. Open your console and type the following command:

$ mysql -u root -p

 

Fig.04: Ubuntu test Mysql installation

 

If you type your password correctly, the you will see the mysql prompt.

#3 – Securing access to MySQL

If we are going to use MySQL as a production database, we may want to secure it. MySQL provides a shell script to help us securing it. Just type the following command on your console:

$ sudo mysql_secure_installation

 

Here are the steps to do it.

  1. ENTER YOUR ROOT PASSWORD
  2. Enter your current root password to continue to the next step.
  3. Fig.05: MySQL enter your root db password
  4. 2.CHANGE THE ROOT PASSWORD
  5. If you want to change it, press Y. Otherwise, press N.
  6. Fig.06: MySQL security
  7. 3.REMOVE ANONYMOUS USER
  8. It is recommended to remove anonymous user to mitigate risk who can log in into your database.
  9. Fig.07: MySQL security
  10. 4.DISALLOW ROOT LOGIN REMOTELY
  11. To make sure that no one remote your database as root from another machines, we need to disallow root login remotely.
  12. Fig.08: MySQL security
  13. 5.REMOVE TEST DATABASE
  14. Sometimes some MySQL installation will create a database named ëtestí for testing purpose. We can remove it if we donít use it.
  15. Fig.09: MySQL security
  16. 6.RELOAD PRIVILEGE TABLES
  17. Then we need to reloading the privilege tables to ensure all changes made so far will take effect immediately.
  18. Fig.10: MySQL security
  19. 7.DONE
  20. Fig.11: MySQL security
  21. PHP Installation For Server Side Scripting
  22. Since PHP is popular, a lot of websites is built using PHP language. As of January 2013, PHP was installed on more than 240 millions websites. Now we are going to install PHP on Ubuntu 14.04
  23. #1 – Download and install PHP
  24. As usual, we can download and install PHP using apt-get command. Just type the following command on your Ubuntu console or over the ssh based session:
  25. $ sudo apt-get install php5-fpm

Fig.12: Install PHP for Server Side Processing on Ubuntu

 

And wait for the installation to complete.

Configure Nginx to work with PHP and MySQL Server on Ubuntu

Now we have all components installed. The next step is we need to configure Nginx with PHP and MySQL. Let’s start to configure them.

#1 – Configure PHP5-FPM

PHP5-FPM configuration file is located at /etc/php5/fpm/php.ini. Open it with your text editor

$ sudo vi /etc/php5/fpm/php.ini

 

Change this parameter, from:

cgi.fix_pathinfo=1

 

to:

cgi.fix_pathinfo=0

 

Save and close the file and then restart php5-fpm service, type:

$ sudo service php5-fpm restart

#2 – Configure Nginx

Nginx configuration file is located at /etc/nginx/nginx.conf. But basically, we don’t need to touch it. The configuration of nginx website is located in /etc/nginx/sites-available/default file.

Open it, and uncomment lines:

location ~ \.php$ {

fastcgi_split_path_info ^(.+\.php)(/.+)$;

#       # NOTE: You should have  cgi.fix_pathinfo = 0;  in php.ini

#

#       # With php5-cgi alone:

#        fastcgi_pass 127.0.0.1:9000;

#       # With php5-fpm:

fastcgi_pass unix:/var/run/php5-fpm.sock;

fastcgi_index index.php;

include fastcgi_params;

}

Then restart the services.

$ sudo service nginx restart

 

Please make sure, on Ubuntu 14.04, we cannot use fastcgi_pass 127.0.0.1:9000. So make sure that the line is commented. Otherwise, on my machine, I got this error :

$ tail /var/log/nginx/error.log

2014/11/04 16:57:04 [emerg] 3216#0:  fastcgi_pass  directive is not allowed here in /etc/nginx/sites-enabled/default:59

2014/11/04 16:58:21 [emerg] 3256#0:  fastcgi_pass  directive is not allowed here in /etc/nginx/sites-enabled/default:59

 

On Ubuntu 14.04, I use the following line:

fastcgi_pass unix:/var/run/php5-fpm.sock

 

When I restart the Nginx and I still got the following error message:

 

2014/11/04 17:02:05 [emerg] 3295#0:  fastcgi_pass  directive is not allowed here in /etc/nginx/sites-enabled/default:61

2014/11/04 17:04:58 [emerg] 3410#0:  fastcgi_pass  directive is not allowed here in /etc/nginx/sites-enabled/default:61

 

Please make sure that you already uncomment this line:

location ~ \.php$ {

#3 – Configure MySQL

After the configuration section is done, now we need to test them to make sure that our configuration is working as required. On Ubuntu 14.04 the root document folder is located in /usr/share/nginx/html. So create a file called /usr/share/nginx/html/phpinfo.php with the following code:

<? phpinfo(); ?>

After restarting PHP-FPM and Nginx, open the browser and browse to the php file, we got only a blank screen. No error message on the screen. No error message on PHP-FPM and Nginx log file.

 

Then we changed /usr/share/nginx/html/phpinfo.php file code on the root document of Nginx, as follows:

<?php phpinfo(); ?>

And then open the browser again and type url http://your_ip_address/phpinfo.php

 

It seem that by default, we can not use short php-tag like this:

<? … your code … ?>

To enable short php tag, we need to change the value of short_open_tag parameter on php.ini file:

 

Change the value from Off to On. Then restart your php5-fpm :

sudo service php5-fpm restart

 

Then try again to test your phpinfo file. Next, we will see if the MySQL support is enabled or not. Scroll down the php configuration screen on your browser, if you see MySQL block there, then MySQL support already enabled.

 

You are now ready to use Nginx, PHP5 and MySQL on Ubuntu server. I hope this quick article help anyone who wish to install Linux, Nginx, PHP and MySQL on Ubuntu 14.04.

Install Apache server

To install the port:

# cd /usr/ports/www/apache24/ && make install clean

 

Or, to add the package:

# pkg install www/apache24

 

Sample outputs:

Fig. 01: Install apache

Starting up Apache service on boot

Add following to the end of “/etc/rc.conf” file to launch Apache at start up:

echo  apache24_enable= YES   >> /etc/rc.conf

STARTING / STOPPING / RESTARTING APACHE SERVER

To start Apache to make sure it works:

# /usr/local/etc/rc.d/apache24 start

 

To restart Apache server:

# /usr/local/etc/rc.d/apache24 restart

 

To stop Apache server:

# /usr/local/etc/rc.d/apache24 stop

 

You can also use the service command for starting/stoping/restarting Apache server on FreeBSD:

service command to control Apache server ##

service apache24 start

service apache24 restart

service apache24 stop

service apache24 status

Sample outputs:

Fig.02: Starting/Stopping Apache

Note: If you are getting this error “Could not reliably determine the server s fully qualified domain name, using 127.0.0.1.” Set the ‘ServerName’ directive globally to suppress this message:

Add next line to /usr/local/ect/apache24/httpd.conf file:

ServerName localhost

Replace localhost with the server’s domain name which can be obtained with:

# hostname -f

Setting up MySQL server

The package or port to be installed will depend on available MySQL version. As of this writing, the maximum available version is 5.6.

Install MySQL server

To install the port:

# cd /usr/ports/databases/mysql56-server/ && make install clean

 

or, to add the package:

# pkg install databases/mysql56-server

 

Fig.03: Installing mysql database server

Install MySQL client

To install the port:

# cd /usr/ports/databases/mysql56-client/ && make install clean

 

or, to add the package:

# pkg install databases/mysql56-client

Starting up Mysql server service on boot

Finally, /etc/rc.conf must contain the following line to allow the MySQL server to start:

echo  mysql_enable= YES   >> /etc/rc.conf

Starting / stopping / restarting Mysql server

To start the Mysql server type:

# /usr/local/etc/rc.d/mysql-server start

 

To restart the Mysql server type:

# /usr/local/etc/rc.d/mysql-server restart

 

To stop the Mysql server type:

# /usr/local/etc/rc.d/mysql-server stop

 

You can also use the service command for starting/stoping/restarting mysql server on FreeBSD:

command to start/stop mysql servers on a FreeBSD 10 ##

service mysql-server start

service mysql-server restart

service mysql-server stop

service mysql-server status

Sample outputs:

Fig.04: Starting/Stopping mysql server

Setting up Mysql server passwords

The default is set to allow anyone to have full access. It’s very important that you set up passwords. To set a password on the anonymous accounts use:

# mysql -u root

 

Run the following sql queries at mysql> prompt (replace host_name with actual system host name which can be obtained with hostname -f command:

mysql> SET PASSWORD FOR   @ localhost  = PASSWORD( newpwd-here );

mysql> SET PASSWORD FOR   @ host_name  = PASSWORD( newpwd-here );

mysql> quit

Bye

To set a password for the root account use:

# mysql -u root

 

Run the following sql queries at mysql> prompt:

mysql> SET PASSWORD FOR  root @ localhost  = PASSWORD( newpwd-here );

mysql> SET PASSWORD FOR  root @ host_name  = PASSWORD( newpwd-here );

mysql>  quit

Bye

NOTE: An alternative method to set a password for the MySQL root user is to run the following command:

/usr/local/bin/mysqladmin -u root password  PASSWORD-HERE

See “MySQL Change root Password” tutorial for more information.

After setting the password, here is how you shutdown mysqld server:

# mysqladmin -u root -p shutdown

 

Sample outputs:

Enter password:

TIP: IF YOU “FORGET” THE ROOT PASSWORD, HERE IS HOW YOU CAN RESET IT

Stop mysqld with this command:

# /usr/local/etc/rc.d/mysql-server.sh stop

 

Modify the start command to add this option to the command line. Do not leave this option on for long. Only for when you need it. It bypasses all usual mysql security:

-Sg|–skip-grant-tables

This option causes the server not to use the privilege system at all. This gives everyone full access to all databases! (You can tell a running server to start using the grant tables again by executing mysqladmin flush-privileges or mysqladmin reload.)

Modify it in /usr/local/etc/rc.d/mysql-server.sh:

/usr/local/bin/safe_mysqld –user=mysql –skip-grant-tables > /dev/null & && echo -n   mysqld

Start mysqld:

# /usr/local/etc/rc.d/mysql-server.sh start

 

Connect to mysql:

# mysql

 

Look out because this next step will reset the passwords for all root users. Make sure that’s what you want to do. You may wish to restrict this SQL by including an “and host = ‘something ” clause. Inspect existing users with “SELECT host, user from user;“. Select the mysql database and reset the password:

mysql> use mysql

mysql> update user set password = PASSWORD( secret ) where user =  root ;

mysql> quit

=> Do not forget to undo that mysql bypass i.e. Stop mysqld with: /usr/local/etc/rc.d/mysql-server.sh stop

=> Remove the option from the vi /usr/local/etc/rc.d/mysql-server.sh and remove –skip-grant-tables options.

=> Restart mysqld with: /usr/local/etc/rc.d/mysql-server.sh start

=> See “Recover MySQL root Password” tutorial for more information.

Install PHP

When you build PHP, you need to add the configuration option so that PHP build includes support for the Apache server. Type the following commands:

# cd /usr/ports/lang/php56

# make config

 

When the menu comes up to select/deselect various build options. You should select:

Fig.05: Build PHP using ports collection

 

Now you will do the make clean command. I normally do these commands all in one but to get the configuration menu, I do them apart.

# make install clean

Install mod_php for Apache

Type the following commands to build mod_php for Apache:

# cd /usr/ports/www/mod_php56

# make install clean

 

Sample outputs:

Fig.06: Install mod_php for Apache

Install php extensions

If you aren’t sure if it’s or you didn’t check it with your MySQL install, you will do it the commands the same way so you get the menus to configure to add support for both MySQL and MySQLi to communicate with the MySQL server.

# cd /usr/ports/lang/php56-extensions/

# make config

 

Fig.07: Install popular extensions for Apache

 

You may also select other extensions as per your PHP apps requirements. Then finish up with:

# make install clean

Configure mod_php

To configure it you will type the following command that just makes a copy of a file:

# cp /usr/local/etc/php.ini-development /usr/local/etc/php.ini

To configure Apache and open the file:

# ee /usr/local/etc/apache24/httpd.conf

 

I use ee (feel free to use vi or Emacs) text editor for simple edits, look for this line:

DirectoryIndex index.html

And change it so it reads as follows:

DirectoryIndex index.html index.htm index.php

Find and set the following values as per your domain, IP, and port number:

ServerAdmin webmaster@cyberciti.biz

ServerName www.cyberciti.biz:80

Listen :80

Save and close the file. Create a file called /usr/local/etc/apache24/modules.d/001_mod_php.conf as follows:

# cat /usr/local/etc/apache24/modules.d/001_mod_php.conf

<FilesMatch  \.php$ >

SetHandler application/x-httpd-php

</FilesMatch>

<FilesMatch  \.phps$ >

SetHandler application/x-httpd-php-source

</FilesMatch>

Now restart Apache server:

# /usr/local/etc/rc.d/apache24 restart

 

OR

# service apache24 restart

Test your setup

Create a file called /usr/local/www/apache24/data/test.php:

# vi /usr/local/www/apache24/data/test.php

Append the following code:

<?php

phpinfo();

?>

Save and close the file. Fire a web-browser and type the url:

http://your-domain-name/test.php

http://your-ip-address/test.php

Sample outputs:

Configuration

You need to edit the file /etc/php5/mods-available/suhosin.ini, enter:

# vi /etc/php5/mods-available/suhosin.ini

 

You can see comma separated whitelist of functions are not allowed to be called:

suhosin.executor.func.blacklist = assert,unserialize,exec,popen,proc_open,passthru,shell_exec,system,hail,parse_str,mt_srand

suhosin.executor.eval.whitelist = assert,unserialize,exec,popen,proc_open,passthru,shell_exec,system,hail,parse_str,mt_srand

Save and close the file. You need to restart php5-fpm. I suggest you see the configuration page for a complete list of possible configuration options.

Error: your composer.lock file is not up to date, run “composer update” to install newer dependencies

How do I install composer command for my PHP installation on Debian or Ubuntu Linux running LAMP or LEMP stack?

How do I Install and use Composer on running Ubuntu Linux server and fix this problem for mediawiki installation and/or manage and install PHP packages and dependencies for my project?

 

Composer is a dependency manager tool for PHP. It installs and updates the libraries for your project. It is not a package manager like yum command or apt-get command.

 

It is desgined to use with each individual project like Mediawiki or your own custom app written in PHP.

There are many open source projects and frameworks written in php use Composer to manage and install their packages and dependencies.

In this tutorial you will learn how to install composer globally on Debian or Ubuntu Linux server. The following instructions should also work with RHEL/CentOS Linux 7.x or any other modern Linux distro.

The problem

When you try to update mediawiki to v1.26.0 using the following command:

[wwwuser@server1.cyberciti.biz:~/wiki]$ php update.php

 

You will will get the following error:

MediaWiki 1.26.0 Updater

How does composer work?

To use Composer you need to create or use composer.json file supplied by your vendor such as mediawiki. This file defines the dependencies of php app or project. Here is sample file from mediawiki project:

{

name :  mediawiki/core ,

description :  Free software wiki application developed by the Wikimedia Foundation and others ,

keywords : [ mediawiki ,  wiki ],

homepage :  https://www.mediawiki.org/ ,

authors : [

{

name :  MediaWiki Community ,

homepage :  https://www.mediawiki.org/wiki/Special:Version/Credits

}

],

license :  GPL-2.0+ ,

support : {

issues :  https://bugs.mediawiki.org/ ,

irc :  irc://irc.freenode.net/mediawiki ,

wiki :  https://www.mediawiki.org/

},

require : {

composer/semver :  1.0.0 ,

cssjanus/cssjanus :  1.1.1 ,

ext-iconv :  * ,

liuggio/statsd-php-client :  1.0.16 ,

oyejorge/less.php :  1.7.0.9 ,

mediawiki/at-ease :  1.1.0 ,

oojs/oojs-ui :  0.12.12 ,

php :  >=5.3.3 ,

psr/log :  1.0.0 ,

wikimedia/assert :  0.2.2 ,

wikimedia/cdb :  1.3.0 ,

wikimedia/composer-merge-plugin :  1.3.0 ,

wikimedia/ip-set :  1.0.1 ,

wikimedia/utfnormal :  1.0.3 ,

wikimedia/wrappedstring :  2.0.0 ,

zordius/lightncandy :  0.21

}

}

How do I install dependencies defined in composer.json file?

Simply type the following command to download and install all dependencies for your app/project:

$ composer install

 

OR switch to core project directory such as /var/www/html/wiki and run:

$ cd /var/www/html/wiki && composer install –no-dev

 

Sample outputs:

Generating optimized autoload files

The above will also create composer.lock file which can be used to update the dependencies later on to the latest version.

How do I update composer.lock file?

If there is no .lock file, this tool will create one based on the dependencies from the .json file. To fetch the dependent libraries to newer versions, run the following command i.e. if you have an existing composer.lock file you will need to run it as follows:

$ composer update

 

OR switch to core project directory such as /var/www/html/wiki and run:

$ cd /var/www/html/wiki/ && composer update –no-dev

 

Sample outputs:

ComposerHookHandler::onPreUpdate

Writing lock file

Generating optimized autoload files

Finally updating mediawiki to version 1.26.0

Now mediawiki will be updated without any problem as composer already fetched required libs for your php app:

$ cd /var/www/html/wiki/

$ php update.php

Command summary

This tutorial described how to install the composer and update mediawiki. But, if you just need the composer tool for your own project, just run the following commands:

$ sudo apt-get install curl php5-cli git

$ sudo curl -sS https://getcomposer.org/installer | sudo php — –install-dir=/usr/local/bin –filename=composer

$ composer

 

Now create your own .json file:

$ cd /my/cool/project/

$ vi composer.json

 

Install the dependencies for your project from composer.json, enter:

$ composer install

 

To update the dependencies for your project:

$ composer update

 

And, there you have it composer installed and working for your LAMP project. For further information please see the official composer project documentation here.

HP 7 provides 2x faster performance and 50% better memory consumption than PHP version 5.6. How do I install PHP 7 on Ubuntu Linux version 14.04 LTS server? How do I install PHP 7 with PHP-FPM in along with Nginx web server?

 

You need to install a PPA called ondrej/php. This allows you to co-install PHP versions 5.6 and 7.0. The latest version of PHP 7 is 7.0.5 and you will learn how to install the same on Ubuntu 14.04 LTS server.

Configure a PPA for co-installable PHP 5.6 + 7.0

Type the following command:

$ sudo apt-get install -y language-pack-en-base

$ sudo LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php

 

OR

$ sudo add-apt-repository ppa:ondrej/php

]]> https://wiki.shopingserver.com/install-php-7-ubuntu-linux-14-04-lts/feed/ 0 How to fix Httpoxy a CGI PHP/Nginx/Apache/Go application vulnerability on Linux or Unix https://wiki.shopingserver.com/fix-httpoxy-cgi-php-nginx-apache-go-application-vulnerability-linux-unix/ https://wiki.shopingserver.com/fix-httpoxy-cgi-php-nginx-apache-go-application-vulnerability-linux-unix/#respond Thu, 04 Jan 2018 08:11:18 +0000 http://wiki.shopingserver.com/?p=18103 A

serious vulnerability was discovered in how CGI scripts are used by Linux or Unix that use PHP, Go, Python, and other scripting languages. How do I fix Httpoxy a CGI application vulnerability on Linux or Unix for HAProxy, Varnish, Nginx, PHP, Go, Python, Tomcat and others?

 

httpoxy is a set of vulnerabilities that affect application code running in CGI, or CGI-like environments. It comes down to a simple namespace conflict:

RFC 3875 (CGI) puts the HTTP Proxy header from a request into the environment variables as HTTP_PROXY

HTTP_PROXY is a popular environment variable used to configure an outgoing proxy

This leads to a remotely exploitable vulnerability. If you’re running PHP or CGI, you should block the Proxy header. This attack use HTTP_PROXY for Man-in-the-Middle” attack. The following web servers, web frameworks and programming languages are affected:

Go lang (CVE-2016-5386)

PHP lang (CVE-2016-5385)

HHVM (CVE-2016-1000109)

Python (CVE-2016-1000110)

Apache Tomcat (CVE-2016-5388)

Servers Apache (CVE-2016-5387)/Nginx/Varnish/Httpoxy.

Disro – RHEL and CentOS and others.

Patch your OS and Apps

First install all available updates for your operating system and application software such as Apache, PHP, Nginx and more:

$ sudo apt-get update && sudo apt-get upgrade

 

OR

$ sudo dnf update

 

OR

$ sudo yum update

Httpoxy mitigation for Nginx proxy server

Edit your nginx.conf or fastcgi_params file:

# vi /etc/nginx/ fastcgi_params

 

Add the following directives:

fastcgi_param  HTTP_PROXY    ;

When proxying HTTP requests to an upstream application, it’s wise to set any Proxy header to the empty string, in case the upstream application is running on a vulnerable platform (added in your nginx.conf’s when load balancing and proxying HTTP traffic):

proxy_set_header Proxy   ;

Save and close the file. Reload/restart the nginx server:

# systemctl reload nginx

Httpoxy mitigation for Apache server

You can use mod_headers. Edit /etc/httpd/conf.d/site.conf or httpd.conf :

# vi /etc/httpd/conf.d/site.conf

 

Add the following directives:

RequestHeader unset Proxy

Save and close the file. Restart the apache server:

# systemctl restart httpd

 

http-request del-header Proxy

Httpoxy mitigation using HAProxy

Edit /etc/haproxy/haproxy.cfg and edit/append as follows to remove Proxy header:

http-request del-header Proxy

Restart the Httpoxy:

# systemctl restart haproxy

Httpoxy mitigation using Varnish

Edit the /etc/varnish/default.vcl and edit/append as follows to remove Proxy header (find and add in sub vcl_recv { … } section):

unset req.http.proxy;

Save and close the file. Restart the varnish:

# systemctl restart varnish

Httpoxy mitigation for PHP/Go lang cgi apps

You need to configure your web application firewall (such as Nginx) to remove the Proxy header from incoming HTTP requests. See above for Nginx and Apache proxy specific info.

Fixing your php app by editing .php file

Edit your PHP file and make sure he following statement near the top, after <?php:

<?php

/* Warning: Not tested and may not be effective */

putenv( HTTP_PROXY= ); $_SERVER[HTTP_PROXY] =   ;

 

/* NOTE */

/* If you are running PHP under Apache/mod_php, also add after the above: */

apache_putenv( HTTP_PROXY ,   );

 

/* rest of your php script */

Save and close the file.

Fixing your php app by editing go program file

Edit the following changes to your program as follows:

import  os

os.Unsetenv( HTTP_PROXY )

Verification

To fix the issue, temporarily install the following as a CGI script on your server and make it executable (say at /var/www/html/cgi-bin/test.cgi):

#!/bin/sh

echo  Content-Type:text/plain

​echo

echo  HTTP_PROXY= $HTTP_PROXY

Save and close the file. Make it executable:

chmod +x test.cgi

 

Call it as follows:

curl -H  Proxy: AFFECTED  http://your-server-ip-or-name/cgi-bin/test.cgi

 

If you see the following output, your server is unaffected:

HTTP_PROXY=

If instead you see the following, or any other output, your server may be affected and you should apply one of the mitigations as discussed above:

HTTP_PROXY= AFFECTED

am getting the following error in my /var/log/php7.0-fpm.log file:

“ERROR: failed to prepare the stderr pipe: Too many open files (24)”

How do I fix this problem?

 

You need to set open file descriptor rlimit for the PHP master process. The default value is system defined but one can increase it as per needs.

php-fpm too many open files error and solution

Edit php-fpm.conf

# vi /etc/php/7.0/fpm/php-fpm.conf

 

Find rlimit_files

;rlimit_files = 1024

 

And update it as follows (or as per your need):

rlimit_files = 4096

 

Save and close the file. Restart php7-0.fpm, run:

# systemctl restart php7.0-fpm

Increase FD limit at the OS level

Find user/group name:

$ grep ^user /etc/php/7.0/fpm/pool.d/www.conf

$ grep ^group /etc/php/7.0/fpm/pool.d/www.conf

www-data

www-data

Edit /etc/security/limits.conf, enter:

# vi /etc/security/limits.conf

 

Append as follows (replace user/group name with your actual names):

www-data       soft    nofile  4096

www-data       hard    nofile  4096

Restart required process. Save and close the file. Verify it:

$ su – www-data

 

To see the hard and soft values, issue the command as follows:

$ ulimit -Hn

$ ulimit -Sn
