Gitlab服务不能启动postgresql

源博文：http://www.zxmseed.com/blog/911081

1、查看启动的服务

-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

发现没有postgresql项

2、查看postgresql报错

[root@localhost ~]# su - gitlab-psql
-sh-4.1$ cat /var/log/gitlab/postgresql/current
postgresql启动异常，To reduce the request size (currently  bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers
显示共享内存不足

3、调整postgresql配置文件

/var/opt/gitlab/postgresql/data/postgresql.conf

修改：shared_buffers 为合适的大小：
shared_buffers =  # min 128kB

4、重启gitlab

gitlab-ctl start
