今早Linux系统重启apache出现VirtualHost overlap on port 80

Linux系统重启apache出现：

[root@localhost conf]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [Wed Jul 16 06:52:43 2008] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Jul 16 06:52:43 2008] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Jul 16 06:52:43 2008] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Jul 16 06:52:43 2008] [warn] NameVirtualHost 124.254.31.4:80 has no VirtualHosts

看上面提示，发现了，apache虚拟主机出问题，警告：默认监听端口80上有重叠，在我们正常配置虚拟主机时，linux系统配置，XXX.conf 虚拟配置文件，一般都是默认访问在第一个站，表明虚拟主机没配置好。

解决方法：
编辑虚拟主机配置文件，改两处地方就可以了。

1.一处
NameVirtualHost *:80

2.二处


DocumentRoot /home/wwwroot/
ServerName xxx.com

[root@localhost conf]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
