使用Docker部署openGauss國產數據庫的操作方法

Posted on by

一、openGauss介紹

1.openGauss簡介

openGauss是一款支持SQL2003標準語法，支持主備部署的高可用關系型數據庫。

2.openGauss產品定位

  • 多種存儲模式支持復合業務場景，新引入提供原地更新存儲引擎。
  • NUMA化數據結構支持高性能。
  • Paxos一致性日志復制協議，主備模式，CRC校驗支持高可用。
  • 支持全密態計算、賬本數據庫等安全特性，提供全方位端到端的數據安全保護。
  • 通過Table Access Method接口層支持多存儲引擎。

3.支持的架構和操作系統版本

x86-64 CentOS 7.6
ARM64 openEuler 20.03 LTS

二、檢查宿主機環境

1.檢查系統版本

[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

2.檢查Docker狀態

[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core) 
[root@node ~]# systemctl status docker

三、下載openGauss鏡像

1.進入docker官方鏡像倉庫

在這裡插入圖片描述

2.openGauss鏡像介紹

1.從3.0版本開始（包括3.0版本）
2.容器采用openGauss數據庫Lite版本
3.默認啟動後空載內存小於200M
4.添加vi，ps，等基礎命令

3.下載openGauss鏡像

[root@node openguass]# docker pull enmotech/opengauss:3.0.0
3.0.0: Pulling from enmotech/opengauss
22c5ef60a68e: Pull complete 
28692a7bf40a: Pull complete 
53d8b65999fe: Pull complete 
2feb7fb751a7: Pull complete 
21970696c490: Pull complete 
Digest: sha256:b8a21dfa15d57476528051f1b8b138dac45cfbad3ef97cba2b340433476147f8
Status: Downloaded newer image for enmotech/opengauss:3.0.0
docker.io/enmotech/opengauss:3.0.0

四、創建openGauss單節點容器

1.創建數據目錄

mkdir -p /data/openguass/

2.創建openGauss容器

docker run --name opengauss -d --restart always --privileged=true  -e GS_PASSWORD=Admin@123456  \
    -v /data/opengauss/mysql:/var/lib/opengauss  -u root -p 15432:5432 \
    enmotech/opengauss:3.0.0

GS_PASSWORD：設置openGauss數據庫的超級用戶omm以及測試用戶gaussdb的密碼
GS_NODENAME：數據庫節點名稱，默認為gaussdb。
GS_USERNAME：數據庫連接用戶名，默認為gaussdb。
GS_PORT：數據庫端口，默認為5432。

3.查看openGauss容器狀態

[root@node openguass]# docker ps
CONTAINER ID   IMAGE                                 COMMAND                  CREATED          STATUS          PORTS                                                                                                                             NAMES
b5abda90d924   enmotech/opengauss:3.0.0              "entrypoint.sh gauss…"   25 seconds ago   Up 24 seconds   0.0.0.0:15432->5432/tcp, :::15432->5432/tcp

4.連接測試openGauss

[root@node openguass]# docker exec -it 360296c286c9 /bin/bash
root@360296c286c9:/# su - omm
omm@360296c286c9:~$ gsql
gsql ((openGauss 3.0.0 build 02c14696) compiled at 2022-04-01 18:12:34 commit 0 last mr  )
Non-SSL connection (SSL connection is recommended when requiring high-security)
Type "help" for help.

omm=#

5.外部遠程連接

[admin@master ~]$ gsql -d postgres -U gaussdb  -W'Admin@123456' -h 192.168.3.167 -p15432
gsql ((openGauss 3.1.0 build 4e931f9a) compiled at 2022-09-29 14:19:24 commit 0 last mr  )
Non-SSL connection (SSL connection is recommended when requiring high-security)
Type "help" for help.

五、創建主從復制的openGauss容器

1.下載運行腳本

wget https://raw.githubusercontent.com/enmotech/enmotech-docker-opengauss/master/create_master_slave.sh

2.腳本中自定義參數解釋

OG_SUBNET (容器所在網段) [172.11.0.0/24]
GS_PASSWORD (定義數據庫密碼)[Enmo@123]
MASTER_IP (主庫IP)[172.11.0.101]
SLAVE_1_IP (備庫IP)[172.11.0.102]
MASTER_HOST_PORT (主庫數據庫服務端口)[5432]
MASTER_LOCAL_PORT (主庫通信端口)[5434]
SLAVE_1_HOST_PORT (備庫數據庫服務端口)[6432]
SLAVE_1_LOCAL_PORT (備庫通信端口)[6434]
MASTER_NODENAME (主節點名稱)[opengauss_master]
SLAVE_NODENAME （備節點名稱）[opengauss_slave1]

3.查看創建腳本

[root@node openguass]# cat create_master_slave.sh 
#!/bin/bash -e
# Parameters
#!/bin/bash

#set OG_SUBNET,GS_PASSWORD,MASTER_IP,SLAVE_1_IP,MASTER_HOST_PORT,MASTER_LOCAL_PORT,SLAVE_1_HOST_PORT,SLAVE_1_LOCAL_PORT,MASTER_NODENAME,SLAVE_NODENAME

|| {
  echo ""
  echo "ERROR: OpenGauss Database Slave1 Docker Container was NOT successfully created."
  exit 1

echo "OpenGauss Database Slave1 Docker Container created."

4.運行創建腳本

[root@node openguass]# sh create_master_slave.sh 
Please input OG_SUBNET (容器所在網段) [172.11.0.0/24]: 
OG_SUBNET set 172.11.0.0/24

5.查看容器狀態

[root@node openguass]# docker ps
CONTAINER ID   IMAGE                                 COMMAND                  CREATED              STATUS              PORTS                                                                                                                             NAMES
