Hosting multiple websites with a virtual domain


Setting multiple domains on a single server is a very commonly asked question. In fact, it is very easy to do this with virtual host. In this recipe, we will set up two domains on a single server and set up a sub-domain as well. We will also look at IP-based virtual hosts.

Getting ready

You will need access to a root account or an account with sudo privileges.

You will need the Apache server installed and working. This recipe describes configuration for Apache version 2.4
