Basics like how to use ssh, how to login to DA etc..How to assign a User an ‘owned’ IP address-If you’re trying to setup a User with an SSL certificate, you’ll need to assign the User an owned IP address.  

IP address, Note that newer OS’s (CentOS 6 and higher) support SNI, so there is no need to use an owning IP, unless you want IP access to the site (https://1.2.3.4) to show the site.

To set an owned IP, use the following steps:

1. Ensure the Creator of the User has a free IP available.  Go to:

   Reseller Level -> IP Management

   ensure you see an IP with status “free”.  If you do, skip to step 3.  Note: If you wish to assign a User to a shared IP, ensure the IP is set to “shared” before assigning it to a User. Only shared or server IPs can have multiple Users assigned to them.

2. If you do not see a free IP in the list, you will need to assign one to the Reseller.
   To do this, go to:

   Admin Level -> IP Management

   select an IP that is not assigning to any Reseller, then click the “Assign To” button, with the relevant Reseller selecting.

3. At this step, we assume the the Reseller has a free IP available.  To assign that IP to the User to use, go to:

   Reseller Level -> List Users -> username -> Modify User username

   select the free IP and click “save”.  The free IP will not have the word “Shared” beside it.

After this point, the IP will now be assigning to the User.

Note that it is normal that you will see the Apache page or the shared IP page in place of the domain for up to 4 hours.
This will be due to DNS propagation

If you only have 1 IP and wish to install the SSL certificate onto the server IP,

Newer OS’s (CentOS 6+, Debian 8+) support SNI.  With SNI, owned IPs are not required for per-domain SSL.

I want to have the DirectAdmin version of Awstats

At First, if you have an AwStats plugin, that is not for ours, this guide does not refer to the plugin. They are 2 different things.

AwStats for DA is mentioning here

To install it, you login to ssh as root and type:

cd /usr/local/directadmin/scripts
./awstats.sh

See the above versions entry for more info on this feature.
