2.4 httpd three ways to build a virtual web host

############################# #构建Web虚拟主 ##################################
The HTTPD supported virtual host types include the following three kinds.
Domain-based: A different domain name is used for each virtual host, but it is the same for the IP address.
Based on IP address: Different domain names are used for each virtual host, and the respective IP addresses are not the same.
Port-based: Use different TCP port numbers instead of domain names, IP addresses to differentiate different site content.

The client needs to add the domain name resolution in the Hosts file:

192.168.10.11 www.aa.com
192.168.10.11 www.ab.com

####
Test 2 addresses:
1, www.aa.com
2, www.ab.com
