  • 访问GitLab的PostgreSQL数据库-(3)

    1.登陆gitlab的安装服务查看配置文件

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

    查看/etc/passwd文件里边gitlab对应的系统用户

    [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用户

    2.根据上面的配置信息登陆postgresql数据库

    [root@localhost ~]# 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 (9.2.18)
    Type "help" for help.

    gitlabhq_production=#  h    查看帮助命令

    Available help:
    ABORT CREATE FUNCTION DROP TABLE
    ALTER AGGREGATE CREATE GROUP DROP TABLESPACE
    ALTER COLLATION CREATE INDEX DROP TEXT SEARCH CONFIGURATION
    ALTER CONVERSION CREATE LANGUAGE DROP TEXT SEARCH DICTIONARY
    ALTER DATABASE CREATE OPERATOR DROP TEXT SEARCH PARSER
    ALTER DEFAULT PRIVILEGES CREATE OPERATOR CLASS DROP TEXT SEARCH TEMPLATE
    ALTER DOMAIN CREATE OPERATOR FAMILY DROP TRIGGER
    ALTER EXTENSION CREATE ROLE DROP TYPE
