1、查看啟動的服務
-sh-4.1$ gitlab-ctl status warning: gitlab-workhorse: unable to open supervise/ok: access denied warning: logrotate: unable to open supervise/ok: access denied warning: nginx: unable to open supervise/ok: access denied warning: redis: unable to open supervise/ok: access denied warning: sidekiq: unable to open supervise/ok: access denied warning: unicorn: unable to open supervise/ok: access denied
發現沒有postgresql項
2、查看postgresql報錯
[root@localhost ~]# su - gitlab-psql -sh-4.1$ cat /var/log/gitlab/postgresql/current postgresql啟動異常，To reduce the request size (currently 2123759616 bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers
顯示共享內存不足
3、調整postgresql配置文件
/var/opt/gitlab/postgresql/data/postgresql.conf 修改：shared_buffers 為合適的大小： shared_buffers = 1024 # min 128kB
4、重啟gitlab
gitlab-ctl start
