1.登陆gitlab的安装服务查看配置文件

[[email protected] ~]# cat /var/opt/gitlab/gitlab-rails/etc/database.yml

# This file is managed by gitlab-ctl. Manual changes will be

# erased! To change the contents below, edit /etc/gitlab/gitlab.rb

# and run `sudo gitlab-ctl reconfigure`. 

production:

  adapter: postgresql

  encoding: unicode

  collation:

  database: gitlabhq_production    //数据库名

  pool: 10

  username: "gitlab"       //用户名

  password:

  host: "/var/opt/gitlab/postgresql" //主机

  port: 5432

  socket:

  sslmode:

  sslrootcert:

  sslca:

  load_balancing: "hosts":[]

  prepared_statements: false

  statements_limit: 1000

[[email protected] ~]#

查看/etc/passwd文件,确定gitlab对应的系统用户

[[email protected] ~]# cat /etc/passwd

gitlab-www:x:498:498::/var/opt/gitlab/nginx:/bin/false

git:x:497:497::/var/opt/gitlab:/bin/sh

gitlab-redis:x:496:496::/var/opt/gitlab/redis:/bin/false

gitlab-psql:x:495:495::/var/opt/gitlab/postgresql:/bin/sh              //gitlab的postgresql用户

2、根据查询出的配置信息登陆postgresql数据库

[[email protected] ~]# su - gitlab-psql       //登陆用户

-sh-4.1$ psql -h /var/opt/gitlab/postgresql -d gitlabhq_production

//连接到gitlabhq_production库

psql (9.6.8)

Type "help" for help. 

gitlabhq_production=# \h              //查看帮助命令
