Implementation of multi-site domain name binding in Apache2 _php Foundation

Configuring the Environment
System: Win7
PHP Version: 5.3.x
MYSQL version: 5.0.27
apache:2.2.4 (WIN32)
To set the method:
Open D:\wamp\bin\apache\Apache2.2.17\conf\httpd.conf
Add at the end
Namevirtualhost *:80
<virtualhost *:80>
DocumentRoot "D:\wamp\www\bbs"
ServerName www.a.com
</VirtualHost>

The configuration should note:
ServerName *:80
Here the * can be changed to native IP such as 192.168.1.11
Namevirtualhost *:80 VirtualHost *:80 remain unchanged
And then to the hosts file to write a sentence: 127.0.0.1 www.a.com
(Location of the Hosts file:-Windows nt/2000/xp/2003/vista default path:%systemroot%\system32\drivers\etc\)
So the domain a.com is tied to the local root directory, the equivalent of http://localhost or
http://127.0.0.1 input www.a.com more convenient AH.

Start Apache service, access with above domain
