H3Cloud OS配置页面访问异常问题处理经验案例

问题现象，H3Cloud OS安装完成后，进行配置，使用chrome浏览器打开配置页面（此处url为http://192.168.113.16:9090）出现无法访问，查看http报文头，http返回代码为200。具体如下图所示：

出现该问题现象时，使用ssh或者xshell等工具登陆到大云服务器，无需进入docker容器，以root用户直接运行“systemctl  status  deploy-manager.service”查看deploy-manager.service服务状态，该服务为大云配置页面对应进程。出现配置页面访问异常，一般是该服务状态异常，如下所示：

[root@cloudos5 ~]# systemctl  status  deploy-manager.service
?.deploy-manager.service - Deploy Manager
   Loaded: loaded (/usr/lib/systemd/system/deploy-manager.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Thu 2016-09-01 12:46:49 CST; 8s ago
 Main PID: 3516 (code=exited, status=143)

该问题解决方法，以root用户权限，运行“systemctl  start  deploy-manager.service ”命令，启动页面对应进程即可解决问题，如下图所示：

如果用命令“systemctl  start  deploy-manager.service”或者“systemctl  restart  deploy-manager.service”启动或重启配置页面对应服务异常，报错或者运行该命令后，再运行“systemctl  status  deploy-manager.service”命令，服务状态依旧异常，请及时联系对应专家处理。
