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

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:3.0.0GS_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/tcp4.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 -WAdmin@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.sh2.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
