起初如下配置
<VirtualHost *:80>
......
........
..........
 </VirtualHost> 
<VirtualHost *:80>
......
........
..........
 </VirtualHost>但从第二个起，每个主机只访问第一个的主机内容。后来才发现文件最前面漏了：NameVirtualHost *，新的配置如下：
NameVirtualHost *
<VirtualHost *:80>
......
........
..........
 </VirtualHost> 
<VirtualHost *:80>
......
........
..........
 </VirtualHost>问题解决
