在自己电脑的虚拟机中安装了gitlab，装完以后请求登陆却报503错误，以前安装nagios和nginx也是出现类似情况都没有解决，请求大神帮助。
具体错误提示：
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.2.15 (CentOS) Server at 192.168.1.212 Port 80
已经解决，本来503重启之后报错502，查看日志发现是端口8080被tomcat占用，kill掉tomcat就OK啦
