访问GitLab的PostgreSQL数据库
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 …………………………………………………………………………………………………………………… gitlabhq_production-# \l //查看数据库 List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges ---------------------+-------------+----------+-------------+-------------+--------------------------------- gitlabhq_production | gitlab | UTF8 | en_US.UTF-8 | en_US.UTF-8 | postgres | gitlab-psql | UTF8 | en_US.UTF-8 | en_US.UTF-8 | template0 | gitlab-psql | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/"gitlab-psql" + | | | | | "gitlab-psql"=CTc/"gitlab-psql" template1 | gitlab-psql | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/"gitlab-psql" + | | | | | "gitlab-psql"=CTc/"gitlab-psql" (4 rows) gitlabhq_production-# \dt //查看多表 List of relations Schema | Name | Type | Owner --------+--------------------------------------+-------+-------- public | abuse_reports | table | gitlab public | appearances | table | gitlab public | application_settings | table | gitlab public | audit_events | table | gitlab public | award_emoji | table | gitlab public | boards | table | gitlab public | broadcast_messages | table | gitlab …………………………………………………………………………………………………………………… gitlabhq_production-# \d abuse_reports //查看单表 Table "public.abuse_reports" Column | Type | Modifiers --------------+-----------------------------+------------------------------------------------------------ id | integer | not null default nextval('abuse_reports_id_seq'::regclass) reporter_id | integer | user_id | integer | message | text | created_at | timestamp without time zone | updated_at | timestamp without time zone | message_html | text | Indexes: "abuse_reports_pkey" PRIMARY KEY, btree (id) gitlabhq_production-# \di //查看索引 List of relations Schema | Name | Type | Owner | Table --------+-----------------------------------------------------------------+-------+--------+-------------------------------- ------ public | abuse_reports_pkey | index | gitlab | abuse_reports public | appearances_pkey | index | gitlab | appearances public | application_settings_pkey | index | gitlab | application_settings public | audit_events_pkey | index | gitlab | audit_events public | award_emoji_pkey | index | gitlab | award_emoji public | boards_pkey | index | gitlab | boards public | broadcast_messages_pkey | index | gitlab | broadcast_messages public | chat_names_pkey | index | gitlab | chat_names public | ci_application_settings_pkey | index | gitlab | ci_application_settings public | ci_builds_pkey | index | gitlab | ci_builds public | ci_commits_pkey | index | gitlab | ci_commits ……………………………………………………………………………………………………………………………………………… gitlabhq_production=# SELECT spcname FROM pg_tablespace; //查看所有表空间 spcname ------------ pg_default pg_global (2 rows) gitlabhq_production-# \q //退出psql -sh-4.1$ exit //退出登录用户 logout
