centos7 卸载 gitlab

标黑的就是关键命令，
先停止gitlab服务，
然后rpm -e卸载，
然后查看剩余gitlab进程，
然后杀死主进程，
然后删除所有相关目录

既然博客园不支持代码中大小写，我还是直接把关键命令单独拉出来吧，不然这排版看着太难受了，前边是上文中的行号：

14 [liuyx@MiWiFi-R3L-srv ~]$ sudo gitlab-ctl stop
30 [liuyx@MiWiFi-R3L-srv ~]$ sudo rpm -e gitlab-ce
32 [liuyx@MiWiFi-R3L-srv ~]$ ps -ef|grep gitlab
50 [liuyx@MiWiFi-R3L-srv ~]$ sudo kill -9 728    （注意这个进程号，和上面命令打印结果相结合）
52 [liuyx@MiWiFi-R3L-srv ~]$ ps -ef|grep gitlab
59 [root@MiWiFi-R3L-srv liuyx]# umount -rf /run/user/1000/gvfs
60 [root@MiWiFi-R3L-srv liuyx]# rm -rf /run/user/1000/gvfs
61 [root@MiWiFi-R3L-srv liuyx]# find / -name gitlab|xargs rm -rf
