How the virtual host is configured

Why use a virtual host?

We should know that in order to access a Web site, the premise is on an operating system, that is, the physical host. Second, the need for host, IP, and server. Because it is so wasteful to maintain a site, we expect to be able to virtualize multiple simultaneous sites (or hosts) on a single physical host, introducing a virtual host.

There are three ways we can define different virtual hosts:

Based on IP--> ip1:80, ip2:80

Based on port--> ip:80, ip:8080

Multiple different host names using the same IP based on the domain name-->

Below we configure each of the three ways to implement the virtual host:

First, close the central host, and open port 8080.

Edit/etc/httpd/conf/httpd.conf

Second, in the/etc//httpd/conf.d/directory, create a virtual.conf file (also can be the configuration of the virtual host directly into the main configuration file)

Edit its contents, as follows
