Docker启动单机版GreenPlum(GPDB)数据库

下载镜像

# docker pull pivotaldata/gpdb-devel

运行容器

# docker run -it -p 15430:15432 --name gpdb0 -v /root/greenplum-db-gpdb-sandbox-tutorials-d734733/:/workspace/gpdb/tutorials -d pivotaldata/gpdb-devel

进入容器

# docker exec -it gpdb0 bash

首次切换gpadmin用户，会自动启动gp数据库

bash-4.1# su gpadmin

/workspace/gpdb/gpAux/gpdemo /workspace/gpdb

This is a demo of the Greenplum Database system. We will create

a cluster installation with master and 6 segment instances

(3 primary & 3 mirror).

GPHOME ................. : /usr/local/gpdb

MASTER_DATA_DIRECTORY .. : /workspace/gpdb/gpAux/gpdemo/datadirs/qddir/demoDataDir-1

MASTER PORT (PGPORT) ... : 15432

SEGMENT PORTS .......... : 25432 25433 25434 25435 25436 25437 25438 25439 25440 25441 25442 25443

NOTE(s):

* The DB ports identified above must be available for use.

* An environment file gpdemo-env.sh has been created for your use.

创建用户

bash-4.1$ createuser -P dlw

Enter password for new role:

Enter it again:

Shall the new role be a superuser? (y/n) n

Shall the new role be allowed to create databases? (y/n) y

Shall the new role be allowed to create more new roles? (y/n) n

NOTICE: resource queue required -- using default resource queue "pg_default"

创建数据库

bash-4.1$ createdb dlwdb

bash-4.1$ psql dlwdb

psql (8.3.23)

Type "help" for help.

执行help查看命令帮助

dlwdb=# help

You are using psql, the command-line interface to PostgreSQL.

Type: \copyright for distribution terms

\h for help with SQL commands

\? for help with psql commands

\g or terminate with semicolon to execute query

\q to quit

在数据库中创建用户

dlwdb=# CREATE USER cyj WITH PASSWORD 'cyj' NOSUPERUSER;

NOTICE: resource queue required -- using default resource queue "pg_default"

CREATE ROLE

创建用户组并添加用户进去

dlwdb=# CREATE ROLE dcyls;

NOTICE: resource queue required -- using default resource queue "pg_default"

CREATE ROLE

dlwdb=# GRANT dcyls TO dlw,cyj;

GRANT ROLE

dlwdb=# \du

List of roles

Role name | Attributes | Member of

-----------+-----------------------------------+-----------

cyj | | {dcyls}

dcyls | Cannot login | {}

dlw | Create DB | {dcyls}

gpadmin | Superuser, Create role, Create DB | {}

重启容器

容器暂停后，下次启动会出现报错，提示ssh连接问题

# docker stop gpdb0

gpdb0

# docker start gpdb0

gpdb0

# docker exec -it gpdb0 bash

bash-4.1# su gpadmin

bash-4.1$ createuser -P dlw

Enter password for new role:

Enter it again:

Shall the new role be a superuser? (y/n) y

createuser: could not connect to database postgres: could not connect to server: Connection refused

Is the server running locally and accepting

connections on Unix domain socket "/tmp/.s.PGSQL.15432"?
