訪問GitLab的PostgreSQL數據庫-(3)

1.登錄gitlab的安裝服務查看配置文件

cat /var/opt/gitlab/gitlab-rails/etc/database.yml 

production:
  adapter: postgresql
  encoding: unicode
  collation:
  database: gitlabhq_production  //數據庫名
  pool: 10
  username: 'gitlab'  //用戶名
  password:
  host: '/var/opt/gitlab/postgresql'  //主機
  port: 5432
  socket:
  sslmode:
  sslrootcert:
  sslca:

 

查看/etc/passwd文件裏邊gitlab對應的系統用戶

[root@localhost ~]# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
gitlab-www:x:496:493::/var/opt/gitlab/nginx:/bin/false
git:x:495:492::/var/opt/gitlab:/bin/sh
gitlab-redis:x:494:491::/var/opt/gitlab/redis:/bin/false
gitlab-psql:x:493:490::/var/opt/gitlab/postgresql:/bin/sh  //gitlab的postgresql用戶

 

2.根據上面的配置信息登錄postgresql數據庫

[root@localhost ~]# su - gitlab-psql     //登錄用戶

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

psql (9.2.18)
Type "help" for help.
