Docker 中部署 Greenplum

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:

Docker 中部署 Greenplum

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-keygen -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: 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 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:

********************************************************************************

[[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

输入 sdw1 密码:gpadmin 

7、Run the gpseginstall utility referencing the hostfile_exkeys file you just created

[[email protected] ~]$ gpseginstall -f /home/gpadmin/gpconfig/seglist

8、Confirm installation

[gpad[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

Docker 中部署 Greenplum

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

source ~/greenplum-db/greenplum_path.sh

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 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

 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。

[[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         guanjiangmiao         0.0.0.0/0       md5
Docker 中部署 Greenplum

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。

[[email protected] greenplum-db]$ pwd

/home/gpadmin/greenplum-db

[[email protected] greenplum-db]$ bin/gpstop -u

[[email protected] greenplum-db]$ psql -d postgres -h 127.0.0.1 -p 5432 -U guanjiangmiao

Password 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

[[email protected] bin]$ gpstop -u

ImportError: No module named site

解决步骤:

(1)查找site相关文件的路径

[[email protected] /]# 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

[[email protected] ~]$ 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

[[email protected] greenplum-db]$ bin/gpstop -u

Traceback (most recent call last):

  File "bin/gpstop", line 9, in <module>

    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!

[[email protected] greenplum-db]$ bin/gpstop -u

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.sh

export MASTER_DATA_DIRECTORY=/home/gpadmin/data/master/gpseg-1

export PGPORT=5432

export PGUSER=gpadmin

(2)让配置生效

source greenplum_path.sh

4、postmaster.pid file does not exist.  is Greenplum instance already stopped?

[[email protected] greenplum-db]$ bin/gpstop -u              

20200511:03:15:35:000105 gpstop:ca279251422f:gpadmin-[INFO]:-Starting gpstop with args: -u
