The Apache web server is the most popular way of serving web content on the Internet. It serves more than half of all of the Internet’s active websites, and is extremely powerful and flexible.
Apache breaks down its functionality and components into individual units that can be customized and configured independently. The basic unit that describes an individual site or domain is called a virtual host. Virtual hosts allow one server to host multiple domains or interfaces by using a matching system. This is relevant to anyone looking to host more than one site off of a single VPS.
Each domain that is configured will direct the visitor to a specific directory holding that site’s information, without ever indicating that the same server is also responsible for other sites. This scheme is expandable without any software limit, as long as your server can handle the traffic that all of the sites attract.
In this guide, we will walk through how to set up Apache virtual hosts on a CentOS 7 VPS. During this process, you’ll learn how to serve different content to different visitors depending on which domains they are requesting.
