一、环境准备
- Docker
- docker-compose
- centos:7.5.1804 的 docker 镜像
- greenplum-db-5.14.0-rhel7-x86_64.bin 二进制文件
1、查看 docker 和 docker-compose 版本
[[email protected] gp]$ docker -v
Docker version 19.03.5, build 633a0ea
[[email protected] gp]$ docker-compose -v
docker-compose version 1.25.1, build a82fef0
2、greenplum-db 下载地址：
https://network.pivotal.io/products/pivotal-gpdb/
二、准备 gp docker 环境
1、创建 GreenPlum Docker 镜像文件 Dockerfile
FROM centos:7.5.1804
RUN yum -y update; yum clean all
RUN yum install -y \
net-tools \
ntp \
openssh-server \
openssh-clients \
less \
iproute \
which; yum clean all
RUN ssh-****** -t rsa -f /etc/ssh/ssh_host_rsa_key -N ''
RUN groupadd gpadmin
RUN useradd gpadmin -g gpadmin
RUN echo gpadmin | passwd gpadmin --stdin
ENTRYPOINT ["/usr/sbin/sshd", "-D"]
2、执行如下命令，创建 docker 镜像
docker build -t gjm-centos-ssh .
3、通过 docker-compose 启动所需要的 greenplum 集群环境。docker-compose.yaml 文件内容如下：
version: "3.2"
services:
mdw:
image: gjm-centos-ssh
container_name: gpdb-mdw
tty: truesdw1:
image: gjm-centos-ssh
container_name: gpdb-sdw1
tty: truesdw2:
image: gjm-centos-ssh
container_name: gpdb-sdw2
tty: true
4、执行如下命令，运行所需要的环境
docker-compose up -d
三、部署 gp
1、通过 docker cp 命令将 greenplum-db-5.14.0-rhel7-x86_64.bin 拷贝到 mdw 的容器中。
docker cp greenplum-db-5.14.0-rhel7-x86_64.bin gpdb-mdw:/home/gpadmin
2、进入 gpdb-mdw 容器中，并切换到gpadmin用户下，查看刚拷贝的bin文件。
[[email protected] ~]$ docker exec -it gpdb-mdw /bin/bash
[[email protected] /]# su - gpadmin
Last login: Sat May 9 07:26:03 UTC 2020 from 2e9585e22e2e on pts/6
3、执行greenplum的bin文件，将其安装在/home/gpadmin目录下.
[[email protected] ~]$ bash greenplum-db-5.14.0-rhel7-x86_64.bin
注意红色字体为需要输入的数据，参考如下：

Installation complete.
Greenplum Database is installed in /home/gpadmin/greenplum-db-5.14.0Pivotal Greenplum documentation is available
for download at http://gpdb.docs.pivotal.io
********************************************************************************
[[email protected] ~]$ ls
greenplum-db greenplum-db-5.14.0 greenplum-db-5.14.0-rhel7-x86_64.bin
4、创建目录 /home/gpadmin/gpconfig/ 和 文件 hostlist、seglist
[[email protected] ~]$ mkdir -p /home/gpadmin/gpconfig/
[[email protected] ~]$ cd /home/gpadmin/gpconfig/
[[email protected] ~]$ vi hostlist
[[email protected] ~]$ vi seglist
hostlist 内容如下
mdw
sdw1
sdw2
seglist 内容如下
sdw1
sdw2
5、Source the path file from your master host’s Greenplum Database installation directory
[[email protected] ~]$ cd
[[email protected] ~]$ source ~/greenplum-db/greenplum_path.sh
6、.Config ssh key exchange(master server and gpadmin user)
[[email protected] ~]$ gpssh-exkeys -f /home/gpadmin/gpconfig/hostlist
7、Run the gpseginstall utility referencing the hostfile_exkeys file you just created
[[email protected] ~]$ gpseginstall -f /home/gpadmin/gpconfig/seglist
8、Confirm installation
[[email protected] ~]$ gpssh -f ~/gpconfig/hostlist -e ls -l $GPHOME
9、Creating the Data Storage Areas
on master
[[email protected] ~]$ mkdir -p ~/data/master
on segments
[[email protected] ~]$ gpssh -f ~/gpconfig/seglist -e "mkdir -p ~/data/primary"
[sdw1] mkdir -p ~/data/primary
[sdw2] mkdir -p ~/data/primary
[[email protected] ~]$ gpssh -f ~/gpconfig/seglist -e "mkdir -p ~/data/mirror"
[sdw1] mkdir -p ~/data/mirror
[sdw2] mkdir -p ~/data/mirror
10、Make a copy of the gpinitsystem_config file to use as a starting point and edit it as you need
[[email protected] ~]$ cp /home/gpadmin/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config ~/gpconfig/gpinitsystem_config
11、modify two line as following
vi ~/gpconfig/gpinitsystem_config
declare -a DATA_DIRECTORY=(/home/gpadmin/data/primary)
MASTER_DIRECTORY=/home/gpadmin/data/master
12、run the initialization utility
[[email protected] ~]$ gpinitsystem -c gpconfig/gpinitsystem_config -h gpconfig/seglist
参考内容如下：
[[email protected] ~]$ gpinitsystem -c gpconfig/gpinitsystem_config -h gpconfig/seglist

13、see the Greenplum Database instance successfully created. You install successfully
如红色字体
四、如何使用 gp
1、配置环境变量
vi ~/.bashrc
增加如下内容
export LD_LIBRARY_PATH=/home/gpadmin/greenplum-db/lib
配置生效
source ~/.bashrc
2、登录 gp
[[email protected] lib]$ psql -d postgres -h localhost -p 5432 -U gpadmin
psql (8.3.23)
Type "help" for help.postgres=# \c
You are now connected to database "postgres" as user "gpadmin".
3、创建测试用户dbdream、授权创建数据库和登录权限。
postgres=# create role dbdream password 'dbdream' createdb login;
NOTICE: resource queue required -- using default resource queue "pg_default"
CREATE ROLE
通常创建用户，赋予login权限基本就够用了，创建用户的语法可以通过\h create role命令来查看。可以通过pg_roles字典来查看
数据库的用户信息。
postgres=# \h create role
Command: CREATE ROLE
Description: define a new database role
Syntax:
CREATE ROLE name [[WITH] option [ ... ]]
where option can be:
SUPERUSER | NOSUPERUSER
| CREATEDB | NOCREATEDB
| CREATEROLE | NOCREATEROLE
| CREATEEXTTABLE | NOCREATEEXTTABLE
[ ( attribute='value'[, ...] ) ]
where attributes and values are:
type='readable'|'writable'
protocol='gpfdist'|'http'|'gphdfs'
| INHERIT | NOINHERIT
| LOGIN | NOLOGIN
| CONNECTION LIMIT connlimit
| [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
| VALID UNTIL 'timestamp'
| IN ROLE rolename [, ...]
| ROLE rolename [, ...]
| ADMIN rolename [, ...]
| RESOURCE QUEUE queue_name
| RESOURCE GROUP group_name
postgres=# select rolname,oid from pg_roles;
rolname | oid
---------+-------
gpadmin | 10
dbdream | 16385
(2 rows)
4、创建完用户后，还需要修改pg_hba.conf文件，来赋予用户的远程登录权限。
[[email protected] gpseg-1]$ cd /home/gpadmin/data/master/gpseg-1
[[email protected] gpseg-1]$ vi pg_hba.conf
增加如下内容
host all dbdream 172.24.0.3/32 md5
5、通过gpstop –u命令重新加载配置文件，使之生效后，dbdream用户即可远程访问数据库了。
