第二十九章 Centos7下Docker安装Postgresql

一、拉取Postgresql镜像文件

[root@m1 ~]# docker pull postgres:latest

二、创建挂载目录并授权

[root@m1 ~]# mkdir -p /data/pgdata

三、创建并启动Postgresql容器

[root@m1 ~]# docker run \
-itd \
-p 5432:5432 \
-v /data/pgdata:/var/lib/postgresql/data \
-v /etc/localtime:/etc/localtime \
-e POSTGRES_PASSWORD=123456 \
--restart always \
--privileged=true \
--name my_postgres \
postgres:latest

四、查看Postgresql是否启动成功

[root@m1 ~]# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED         STATUS         PORTS                                       NAMES
a2a1681b11a9   postgres:latest   "docker-entrypoint.s…"   9 seconds ago   Up 8 seconds   0.0.0.0:5432->5432/tcp, :::5432->5432/tcp   my_postgres

五、查看docker容器日志

[root@m1 ~]# docker logs my_postgres

Postgresql Database directory appears to contain a database; Skipping initialization

2022-01-24 14:53:00.365 CST [1] LOG:  starting Postgresql 14.1 (Debian 14.1-1.pgdg110+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit

2022-01-24 14:53:00.405 CST [1] LOG:  database system is ready to accept connections

六、拉取pgadmin4工具镜像

[root@m1 ~]# docker pull dpage/pgadmin4:latest

七、创建并启动pgadmin4容器

[root@m1 ~]# docker run \
-itd \
-p 5080:80 \
-v /etc/localtime:/etc/localtime \
-e PGADMIN_DEFAULT_EMAIL=[e-mail] \
-e PGADMIN_DEFAULT_PASSWORD=123456 \
--restart always \
--privileged=true \
--name pgadmin \
dpage/pgadmin4

八、查看pgadmin4是否启动成功

[root@m1 ~]# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED          STATUS          PORTS                                            NAMES
eed7a36f995e   dpage/pgadmin4    "/entrypoint.sh"         7 seconds ago    Up 4 seconds    443/tcp, 0.0.0.0:5080->80/tcp, :::5080->80/tcp   pgadmin
a2a1681b11a9   postgres:latest   "docker-entrypoint.s…"   10 minutes ago   Up 10 minutes   0.0.0.0:5432->5432/tcp, :::5432->5432/tcp        my_postgres

九、验证连接

#1.登录pgadmin4，输入启动容器时的邮箱和密码即可

#2.创建新的service连接，连接host：192.168.13.200，默认的用户名为postgres，点击保存即可看到连接成功。
