猿创征文 | 使用Docker部署openGauss国产数据库
一、openGauss介绍
1.openGauss简介
openGauss是一款支持SQL2003标准语法，支持主备部署的高可用关系型数据库。
2.openGauss产品定位
- 多种存储模式支持复合业务场景，新引入提供原地更新存储引擎。
- NUMA化数据结构支持高性能。
- Paxos一致性日志复制协议，主备模式，CRC校验支持高可用。
- 支持全密态计算、账本数据库等安全特性，提供全方位端到端的数据安全保护。
- 通过Table Access Method接口层支持多存储引擎。
3.支持的架构和操作系统版本
x86-64 CentOS 7.6
ARM64 openEuler 20.03 LTS
二、检查宿主机环境
1.检查系统版本
[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
2.检查Docker状态
[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
[root@node ~]# systemctl status docker

三、下载openGauss镜像
1.进入docker官方镜像仓库
2.openGauss镜像介绍
1.从3.0版本开始（包括3.0版本）
2.容器采用openGauss数据库Lite版本
3.默认启动后空载内存小于200M
4.添加vi，ps，等基础命令
3.下载openGauss镜像
[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、创建openGauss单节点容器
1.创建数据目录
mkdir -p /data/openguass/
2.创建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：设置openGauss数据库的超级用户omm以及测试用户gaussdb的密码
GS_NODENAME：数据库节点名称，默认为gaussdb。
GS_USERNAME：数据库连接用户名，默认为gaussdb。
GS_PORT：数据库端口，默认为5432。
3.查看openGauss容器状态
[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.连接测试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.外部远程连接
[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.
openGauss=>
五、创建主从复制的openGauss容器
1.下载运行脚本
wget https://raw.githubusercontent.com/enmotech/enmotech-docker-opengauss/master/create_master_slave.sh
2.脚本中自定义参数解释
OG_SUBNET (容器所在网段) [172.11.0.0/24]
GS_PASSWORD (定义数据库密码)[Enmo@123]
MASTER_IP (主库IP)[172.11.0.101]
SLAVE_1_IP (备库IP)[172.11.0.102]
MASTER_HOST_PORT (主库数据库服务端口)[5432]
MASTER_LOCAL_PORT (主库通信端口)[5434]
SLAVE_1_HOST_PORT (备库数据库服务端口)[6432]
SLAVE_1_LOCAL_PORT (备库通信端口)[6434]
MASTER_NODENAME (主节点名称)[opengauss_master]
SLAVE_NODENAME （备节点名称）[opengauss_slave1]
3.查看创建脚本
[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
