一、环境准备Dockerdocker-composecentos: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
[bigdata@local-vm-320 gp]$ docker -v
Docker version 19.03.5, build 633a0ea
[bigdata@local-vm-320 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:7.5.1804RUN yum -y update; yum clean allRUN yum install -y \ net-tools \ ntp \ openssh-server \ openssh-clients \ less \ iproute \ which; yum clean allRUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N ''RUN groupadd gpadminRUN useradd gpadmin -g gpadminRUN echo gpadmin | passwd gpadmin --stdinENTRYPOINT ["/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: true
sdw1: image: gjm-centos-ssh container_name: gpdb-sdw1 tty: true
sdw2: 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 gp1、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。
[bigdata@local-vm-320 ~]$ docker exec -it gpdb-mdw /bin/bash[root@2e9585e22e2e /]# su - gpadminLast 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.
[gpadmin@2e9585e22e2e ~]$ 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：
********************************************************************************Do you accept the Pivotal Database license agreement? [yes|no]********************************************************************************

4、创建目录 /home/gpadmin/gpconfig/ 和 文件 hostlist、seglist
[gpadmin@2e9585e22e2e ~]$ mkdir -p /home/gpadmin/gpconfig/
[gpadmin@2e9585e22e2e ~]$ cd /home/gpadmin/gpconfig/
[gpadmin@2e9585e22e2e ~]$ vi hostlist
[gpadmin@2e9585e22e2e ~]$ vi seglist
hostlist 内容如下
mdwsdw1sdw2
seglist 内容如下
sdw1sdw2
5、Source the path file from your master host’s Greenplum Database installation directory
[gpadmin@2e9585e22e2e ~]$ cd
[gpadmin@2e9585e22e2e ~]$ source ~/greenplum-db/greenplum_path.sh
6、Config ssh key exchange(master server and gpadmin user)
[gpadmin@2e9585e22e2e ~]$ gpssh-exkeys -f /home/gpadmin/gpconfig/hostlist
输入 sdw1 密码：gpadmin
7、Run the gpseginstall utility referencing the hostfile_exkeys file you just created
[gpadmin@2e9585e22e2e ~]$ gpseginstall -f /home/gpadmin/gpconfig/seglist
8、Confirm installation
[gpadmin@2e9585e22e2e ~]$ gpssh -f ~/gpconfig/hostlist -e ls -l $GPHOME
9、Creating the Data Storage Areas
on master
[gpadmin@2e9585e22e2e ~]$ mkdir -p ~/data/master
on segments
[gpadmin@2e9585e22e2e ~]$ gpssh -f ~/gpconfig/seglist -e "mkdir -p ~/data/primary"[sdw1] mkdir -p ~/data/primary[sdw2] mkdir -p ~/data/primary[gpadmin@2e9585e22e2e ~]$ 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
[gpadmin@67758e384c8c ~]$ 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
[gpadmin@2e9585e22e2e ~]$ gpinitsystem -c gpconfig/gpinitsystem_config -h gpconfig/seglist
参考内容如下：
[gpadmin@2e9585e22e2e ~]$ 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 gp1、配置环境变量
vi ~/.bashrc
增加如下内容
export LD_LIBRARY_PATH=/home/gpadmin/greenplum-db/lib
source ~/greenplum-db/greenplum_path.sh
配置生效
source ~/.bashrc
2、登录 gp
[gpadmin@2e9585e22e2e lib]$ psql -d postgres -h localhost -p 5432 -U gpadmin psql (8.3.23)Type "help" for help.
postgres=# \cYou are now connected to database "postgres" as user "gpadmin".
3、创建测试用户guanjiangmiao、授权创建数据库和登录权限。
postgres=# create role guanjiangmiao password '123qwe' 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 roleCommand: CREATE ROLEDescription: define a new database roleSyntax: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 guanjiangmiao | 16384(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。
[gpadmin@2e9585e22e2e gpseg-1]$ cd /home/gpadmin/data/master/gpseg-1[gpadmin@2e9585e22e2e gpseg-1]$ vi pg_hba.conf
增加如下内容
host all guanjiangmiao 0.0.0.0/0 md5
5、通过gpstop –u命令重新加载配置文件，使之生效后，guanjiangmiao 用户即可远程访问数据库了。
[gpadmin@ca279251422f greenplum-db]$ pwd/home/gpadmin/greenplum-db[gpadmin@ca279251422f greenplum-db]$ bin/gpstop -u
[gpadmin@a5b60ff4b8b9 greenplum-db]$ psql -d postgres -h 127.0.0.1 -p 5432 -U guanjiangmiaoPassword for user guanjiangmiao: psql (8.3.23)Type "help" for help.
postgres=>
6、设置免密登录
cd
vi .pgpass
输入如下内容
10.0.0.100:5432:*:guanjiangmiao:123qwe
chmod 600 .pgpass
五、启动、关闭及状态查看命令参数说明1、启动 gp
在Master主机上运行gpstart启动Greenplum数据库，gpstart 常用的启动参数有以下几个参数：
-a，该模式不需要在启动过程中输入Y进行确认，将直接启动数据库。-m，只启动Master节点，不启动Segment节点，通常在维护的时候使用。-y，只启动Master的primary节点，不启动standby节点。2、停止 gp
不要发出kill命令来结束任何Postgres进程，发出kill -9或者kill -11可能会导致数据库损坏并且妨碍对根本原因的分析。在Master主
机上运行gpstop停止Greenplum数据库，常用参数如下：
-a，不需要输入Y确认是否关闭，将直接关闭数据库-m，只关闭Master节点，一般用于维护模式-r，重启数据库。-u，加载参数文件，使修改的参数生效。pg_hba.conf配置文件和Master上postgresql.conf、pg_hba.conf文件中运行时参数的更改，活动会话将会在它们重新连接到数据库时使用这些更新。很多服务器配置参数需要完全重启系统（gpstop -r）才能激活-M，设置关闭数据库的级别，有三种级别，fast、immediate和smart。 Immediate smart 这是默认的关闭级别，所有连接的会话会收到关闭警告，不允许新链接访问数据库。 gpstop –M immediate，强制关闭数据库，这种方式是不一致的关闭模式，不建议使用。 gpstop –M fast 快速模式，停止所有连接将中断并且回滚3、查看 gp 状态
常用的参数如下：
-s，详细信息。-m，Mirror信息。-f，Master的Standby信息。-e，Segment的Mirror信息。-i，版本信息。六、可能遇到的问题1、ImportError: No module named site
[gpadmin@ca279251422f bin]$ gpstop -uImportError: No module named site
解决步骤：
(1)查找site相关文件的路径
[root@ca279251422f /]# find / -name site.py/home/gpadmin/greenplum-db-5.14.0/ext/python/lib/python2.7/site.py/usr/lib64/python2.7/site.py
(2)增加路径到环境变量
[gpadmin@ca279251422f ~]$ vi .bashrc
增加如下内容
export PYTHONPATH=$PYTHONPATH:/home/gpadmin/greenplum-db-5.14.0/ext/python/lib/python2.7
(3)让配置生效
source ~/.bashrc
2、ImportError: No module named gppylib.mainUtils
[gpadmin@ca279251422f greenplum-db]$ bin/gpstop -uTraceback (most recent call last): File "bin/gpstop", line 9, in from gppylib.mainUtils import *ImportError: No module named gppylib.mainUtils
解决步骤：
source ~/greenplum-db/greenplum_path.sh
3、Reason='Environment Variable MASTER_DATA_DIRECTORY not set!
[gpadmin@ca279251422f greenplum-db]$ bin/gpstop -u20200511:02:37:34:002935 gpstop:ca279251422f:gpadmin-[INFO]:-Starting gpstop with args: -u20200511:02:37:34:002935 gpstop:ca279251422f:gpadmin-[INFO]:-Gathering information and validating the environment...20200511:02:37:34:002935 gpstop:ca279251422f:gpadmin-[CRITICAL]:-gpstop failed. (Reason='Environment Variable MASTER_DATA_DIRECTORY not set!') exiting...
解决步骤：
(1)greenplum_path.sh 增加环境变量
cd /home/gpadmin/greenplum-db
vi greenplum_path.sh
增加内容如下
source ~/greenplum-db/greenplum_path.shexport MASTER_DATA_DIRECTORY=/home/gpadmin/data/master/gpseg-1export PGPORT=5432export PGUSER=gpadmin
(2)让配置生效
source greenplum_path.sh
4、postmaster.pid file does not exist. is Greenplum instance already stopped?
[gpadmin@ca279251422f greenplum-db]$ bin/gpstop -u 20200511:03:15:35:000105 gpstop:ca279251422f:gpadmin-[INFO]:-Starting gpstop with args: -u20200511:03:15:35:000105 gpstop:ca279251422f:gpadmin-[INFO]:-Gathering information and validating the environment...20200511:03:15:35:000105 gpstop:ca279251422f:gpadmin-[ERROR]:-gpstop error: postmaster.pid file does not exist. is Greenplum instance already stopped?
解决步骤：
(1)关闭gp
bin/gpstop -af
(2)启动gp
bin/gpstart -a
[gpadmin@ca279251422f gpseg-1]$ gpstop -af20200511:03:43:08:000464 gpstop:ca279251422f:gpadmin-[INFO]:-Starting gpstop with args: -af20200511:03:43:08:000464
