虚拟主机: 通过一个web服务器，同时提供多个网站服务，多个虚拟主机
主机，占用一个排它性的资源 基于ip 基于port 基于主机名的虚拟主机
把重心主机取消或做成一个虚拟主机 DocumentRoot 配置虚拟主机
IP: <VirtualHost IP1:port> DocumentRoot "/www/a.com" ServerName ServerAdmin Errorlog Customlog <Directory "/www/a.com"> Options AllowOverride Order allow,deny Allow from all </Directory> </VirtualHost>
<VirtualHost IP2:port> DocumentRoot "/www/b.com" ServerName ServerAdmin Errorlog Customlog <Directory "/www/b.com"> Options AllowOverride Order allow,deny Allow from all </Directory> </VirtualHost>
PORT: <VirtualHost IP:port1> DocumentRoot "/www/a.com" ServerName ServerAdmin Errorlog Customlog <Directory "/www/a.com"> Options AllowOverride Order allow,deny Allow from all </Directory> </VirtualHost>
<VirtualHost IP:port2> DocumentRoot "/www/b.com" ServerName ServerAdmin Errorlog Customlog <Directory "/www/b.com"> Options AllowOverride Order allow,deny Allow from all </Directory> </VirtualHost>
