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

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
