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

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

这个问题很好处理，它是ssh自己，看下ssh服务，第一次启动的时候应该是启动脚本里附带了启动sshd服务，之后再启动，需要自己手动启动下sshd服务，此处是centos6.8的系统
bash-4.1$ hostname 3ce34f890d16 bash-4.1$ ssh 3ce34f890d16 ssh: connect to host 3ce34f890d16 port 22: Connection refused bash-4.1$ cat /etc/redhat-release CentOS release 6.8 (Final) bash-4.1$ service sshd start /etc/init.d/sshd: line 33: /etc/sysconfig/sshd: Permission denied Starting sshd: /etc/ssh/sshd_config: Permission denied [FAILED] bash-4.1$ exit exit bash-4.1# service sshd start Starting sshd: [ OK ]
启动sshd后再启动数据库，正常运行

客户端连接
连接之前需要修改pgdb的配置文件，允许客户端所在网络可以连接 配置文件目录可以在初始化pgdb的时候看到
bash-4.1$ cd /workspace/gpdb/gpAux/gpdemo/datadirs/qddir/demoDataDir-1 bash-4.1$ vi pg_hba.conf 添加 host all all 192.16.126.0/24 trust 重启gpdb bash-4.1$ gpstop -r
下载windows客户端
https://www.postgresql.org/ftp/pgadmin/pgadmin3/v1.22.2/win32/
安装之后启动连接
成功连接
