解决[warn] _default_ VirtualHost overlap on port 80, the first has precedence问题在apache2的httpd.c
解决[warn] _default_ VirtualHost overlap on port 80, the first has precedence问题
在apache2的httpd.conf里新增加了1个VirtualHost，域名是www.ligh.com，此时，服务器总共2个VirtualHost ，apachectl restart的时候却出现了下面的警告提示：
?
[warn] _default_ VirtualHost overlap on port 80, the first has precedence
?
大概意思就是说后面新增加的这个VirtualHost 由于端口被占用，不能生效，沿用第一个虚拟主机的配置。
?
检查了一下，发现，原来在httpd.conf里，我没有把#NameVirtualHost *:80前的注释去掉，导致这个没有生效。
?
去掉#之后restart，问题解决，如果有https，则总体修改为
?
NameVirtualHost *:80
NameVirtualHost *:433
?
Linux系统重启apache出现：
?[root@localhost conf]# service httpd restart
Stopping httpd:??????????????????????????????????????????? [? OK? ]

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
<VirtualHost *:80>
? ? DocumentRoot /home/wwwroot/
??? ServerName?xxx.com?[root@localhost conf]# service httpd restart
