CentOS and RHEL 7: Install Linux, Apache, MariaDB, PHP (LAMP) Stack


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.


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


ip a show eth0


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


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

I’m going to use IP address 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 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:


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:




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


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:

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:




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

Sample outputs:
