Docker分布式安装GreenPlum集群
一、创建容器
## 启动docer
[root@zxy_master ~]# systemctl start docker
## 拉取centos镜像,使用6.8和latest下载的镜像，在容器中都没法使用yum
## 使用centos7，可以正常使用yum
[root@zxy_master ~]# docker pull centos:7
7: Pulling from library/centos
2d473b07cdd5: Pull complete
Digest: sha256:c73f515d06b0fa07bb18d8202035e739a494ce760aa73129f60f4bf2bd22b407
Status: Downloaded newer image for centos:7
docker.io/library/centos:7
## 查看镜像
[root@zxy_master /]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
centos 7 eeb6ee3f44bd 6 months ago 204MB
## 创建容器并进入容器
[root@zxy_master /]# sudo docker run -d --name mdw --privileged=true eeb6ee3f44bd /usr/sbin/init
[root@zxy_master /]# sudo docker run -d --name sdw1 --privileged=true eeb6ee3f44bd /usr/sbin/init
[root@zxy_master /]# sudo docker run -d --name sdw2 --privileged=true eeb6ee3f44bd /usr/sbin/init
[root@zxy_master /]# sudo docker run -d --name sdw3 --privileged=true eeb6ee3f44bd /usr/sbin/init
二、启动Docker容器
## 查看所有docker容器
[root@zxy_master /]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e52a14e99e90 eeb6ee3f44bd "/usr/sbin/init" 5 seconds ago Up 3 seconds sdw3
17958fb5ddb1 eeb6ee3f44bd "/usr/sbin/init" 10 seconds ago Up 9 seconds sdw2
8853f886b356 eeb6ee3f44bd "/usr/sbin/init" 18 seconds ago Up 16 seconds sdw1
d4f6ce1daac3 eeb6ee3f44bd "/usr/sbin/init" 9 minutes ago Up 9 minutes mdw
## 启动集群
[root@zxy_master /]# docker start d4f6ce1daac3
dc2a65dbe4bd
[root@zxy_master /]# docker start 8853f886b356
0124f396849e
[root@zxy_master /]# docker start 17958fb5ddb1
ce93908af614
[root@zxy_master /]# docker start e52a14e99e90
433f460ae838
## 查看所有启动docker容器
[root@zxy_master /]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e52a14e99e90 eeb6ee3f44bd "/usr/sbin/init" About a minute ago Up About a minute sdw3
17958fb5ddb1 eeb6ee3f44bd "/usr/sbin/init" About a minute ago Up About a minute sdw2
8853f886b356 eeb6ee3f44bd "/usr/sbin/init" About a minute ago Up About a minute sdw1
d4f6ce1daac3 eeb6ee3f44bd "/usr/sbin/init" 10 minutes ago Up 10 minutes mdw
## 依次启动
[root@zxy_master /]# docker exec -it d4f6ce1daac3 /bin/bash
[root@zxy_master ~]# docker exec -it 8853f886b356 /bin/bash
[root@zxy_master ~]# docker exec -it 17958fb5ddb1 /bin/bash
[root@zxy_master ~]# docker exec -it e52a14e99e90 /bin/bash
三、docker集群部署
1.安装相关的依赖包(所有节点操作)
由于拉取docker的centos镜像是一个简化版本，里面有一些程序没有默认安装，会影响到gp的部署，因为在每个docker容器中安装相关的依赖包
yum install -y net-tools which openssh-clients openssh-server less zip unzip iproute.x86_64
2.免密操作(所有节点操作)
ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key
ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key
/usr/sbin/sshd
3.修改/etc/hosts(所有节点操作)
## 修改为以下内容
172.17.0.2 d4f6ce1daac3
172.17.0.3 8853f886b356
172.17.0.4 17958fb5ddb1
172.17.0.5 e52a14e99e90
172.17.0.2 dw-greenplum-1 mdw
172.17.0.3 dw-greenplum-2 sdw1
172.17.0.4 dw-greenplum-3 sdw2
172.17.0.5 dw-greenplum-4 sdw3
4.修改/etc/sysconfig/network(所有节点操作)
[root@gp1 sysconfig]# cat network
NETWORKING=yes
HOSTNAME=mdw
[root@gp2 sysconfig]# cat network
NETWORKING=yes
HOSTNAME=sdw1
[root@gp3 sysconfig]# cat network
NETWORKING=yes
HOSTNAME=sdw2
[root@gp4 sysconfig]# cat network
NETWORKING=yes
HOSTNAME=sdw3
5.创建用户/用户组(所有节点操作)
groupadd -g 530 gpadmin
useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin
chown -R gpadmin:gpadmin /home/gpadmin
passwd gpadmin
##密码设置为gpadmin
6.关闭防火墙和selinux(所有节点操作)
## 未发现firewalld,安装firewalld
yum -y install firewalld
## 关闭firewalld
systemctl stop firewalld
## 未发现/etc/sysconfig/selinux文件
## 1.安装setroubleshoot-server
[root@d4f6ce1daac3 sysconfig]# yum install setroubleshoot-server
[root@8853f886b356 sysconfig]# yum install setroubleshoot-server
[root@17958fb5ddb1 sysconfig]# yum install setroubleshoot-server
[root@e52a14e99e90 sysconfig]# yum install setroubleshoot-server
## 2.将主机中的selinux文件复制到容器
[root@zxy_master /]# docker cp ../selinux/ d4f6ce1daac3:/etc/
[root@zxy_master /]# docker cp ../selinux/ 8853f886b356:/etc/
[root@zxy_master /]# docker cp ../selinux/ 17958fb5ddb1:/etc/
[root@zxy_master /]# docker cp ../selinux/ e52a14e99e90:/etc/
## 3.在每个容器的/etc/sysconfig中创建全连接
[root@d4f6ce1daac3 sysconfig]# ln -s ../selinux/config selinux
[root@8853f886b356 sysconfig]# ln -s ../selinux/config selinux
[root@17958fb5ddb1 sysconfig]# ln -s ../selinux/config selinux
[root@e52a14e99e90 sysconfig]# ln -s ../selinux/config selinux
## 4.例如：查看文件内容,主要查看SELINUX=disabled
[root@d4f6ce1daac3 sysconfig]# cat selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
## 执行命令成功
[root@d4f6ce1daac3 sysconfig]# getenforce
Disabled
7.将gp上传至容器mdw
[root@zxy_master software]# docker cp greenplum-db-6.4.0-rhel6-x86_64.rpm d4f6ce1daac3:/home/gpadmin
[root@zxy_master software]#
8.安装gp(mdw节点)
## rpm安装greenplum
[root@gp1 gpadmin]# rpm -ivh --relocate /usr/local/=/home/gpadmin/ ./greenplum-db-6.4.0-rhel6-x86_64.rpm
error: Failed dependencies:
