虚拟主机的配置

1．基于IP地址的虚拟主机

ServerName 192.168.16.201:80
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web1"
DirectoryIndex index.html
ErrorLog logs/web1/error_log
CustomLog logs/web1/access_log combined


ServerName 192.168.16.202:80
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web2"
DirectoryIndex default.html
ErrorLog logs/web2/error_log
CustomLog logs/web2/access_log combined

2. 基于域名的虚拟主机
    当Web服务器收到访问请求时，就可以根据不同的DNS域名来访问不同的网站。它的优势就是不需要更多的IP地址，容易配置。
NameVirtualHost 192.168.16.201

ServerName :80
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web1"
DirectoryIndex index.html
ErrorLog logs/web1/error_log
CustomLog logs/web1/access_log combined

ServerName
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web2"
DirectoryIndex default.html
ErrorLog logs/web2/error_log
CustomLog logs/web2/access_log combined

3. 基于端口的配置
Listen 80
Listen 81

ServerName 192.168.16.201:80
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web1"
DirectoryIndex index.html
ErrorLog logs/web1/error_log
CustomLog logs/web1/access_log combined


ServerName 192.168.16.201:81
ServerAdmin [e-mail]
DocumentRoot "/usr/www/web2"
DirectoryIndex default.html
ErrorLog logs/web2/error_log
CustomLog logs/web2/access_log combined
