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
read -p "please input og_subnet (容器所在网段) [172.11.0.0/24]: " og_subnet

read -p "please input master_nodename [opengauss_master]: " master_nodename
master_nodename=${master_nodename:-opengauss_master}
echo "master_nodename set $master_nodename"
read -p "please input slave_nodename [opengauss_slave1]: " slave_nodename
slave_nodename=${slave_nodename:-opengauss_slave1}
echo "slave_nodename set $slave_nodename"
read -p "please input opengauss version [3.0.0]: " version
version=${version:-3.0.0}
echo "opengauss version set $version"
echo "starting "
docker network create --subnet=$og_subnet opengaussnetwork \
|| {
echo ""
echo "error: opengauss database network was not successfully created."
echo "hint: opengaussnetwork maybe already exsist please execute 'docker network rm opengaussnetwork' "
exit 1
}
echo "opengauss database network created."
docker run --network opengaussnetwork --ip $master_ip --privileged=true \
--name $master_nodename -h $master_nodename -p $master_host_port:$master_host_port -d \
-e gs_port=$master_host_port \

-e repl_conn_info="replconninfo1 = 'localhost=$master_ip localport=$master_local_port localservice=$master_host_port remotehost=$slave_1_ip remoteport=$slave_1_local_port remoteservice=$slave_1_host_port'\n" \
enmotech/opengauss:$version -m primary \
|| {
echo ""
echo "error: opengauss database master docker container was not successfully created."
exit 1
}
echo "opengauss database master docker container created."
sleep 30s
docker run --network opengaussnetwork --ip $slave_1_ip --privileged=true \
--name $slave_nodename -h $slave_nodename -p $slave_1_host_port:$slave_1_host_port -d \
-e gs_port=$slave_1_host_port \
-e og_subnet=$og_subnet \

enmotech/opengauss:$version -m standby \
|| {
echo ""
echo "error: opengauss database slave1 docker container was not successfully created."
exit 1
}
echo "opengauss database slave1 docker container created."
4.运行创建脚本
[root@node openguass]# sh create_master_slave.sh please input og_subnet (容器所在网段) [172.11.0.0/24]: og_subnet set 172.11.0.0/24 please input gs_password (定义数据库密码)[enmo@123]: gs_password set enmo@123 please input master_ip (主库ip)[172.11.0.101]: master_ip set 172.11.0.101 please input slave_1_ip (备库ip)[172.11.0.102]: slave_1_ip set 172.11.0.102 please input master_host_port (主库数据库服务端口)[5432]: master_host_port set 5432 please input master_local_port (主库通信端口)[5434]: master_local_port set 5434 please input slave_1_host_port (备库数据库服务端口)[6432]: slave_1_host_port set 6432 please input slave_1_local_port (备库通信端口)[6434]: slave_1_local_port set 6434 please input master_nodename [opengauss_master]: master_nodename set opengauss_master please input slave_nodename [opengauss_slave1]: slave_nodename set opengauss_slave1 please input opengauss version [3.0.0]: opengauss version set 3.0.0 starting 97d6c3667b72511c0f09eea31b54b6c5d315af06252db1a7961b0861069f2b5a opengauss database network created. 24c3c7ba6b162fabbe9ac4e21f4b188ebd49acbbba91e7458d287ad6731ce48f opengauss database master docker container created. 0376996ac00d91173e24ebea274d0750be9093269dcfdf479722c68952aa93a1 opengauss database slave1 docker container created.
5.查看容器状态
[root@node openguass]# docker ps container id image command created status ports names 0376996ac00d enmotech/opengauss:3.0.0 "entrypoint.sh -m st…" about a minute ago up about a minute 5432/tcp, 0.0.0.0:6432->6432/tcp, :::6432->6432/tcp opengauss_slave1 24c3c7ba6b16 enmotech/opengauss:3.0.0 "entrypoint.sh -m pr…" 2 minutes ago up 2 minutes 0.0.0.0:5432->5432/tcp, :::5432->5432/tcp opengauss_master
6.验证主从状态
[root@node openguass]# docker exec -it 24c3c7ba6b16 /bin/bash root@opengauss_master:/# su - omm omm@opengauss_master:~$ gs_ctl query -d /var/lib/opengauss/data/ [2022-10-04 10:13:45.084][346][][gs_ctl]: gs_ctl query ,datadir is /var/lib/opengauss/data ha state: local_role : primary static_connections : 1 db_state : normal detail_information : normal senders info: sender_pid : 319 local_role : primary peer_role : standby peer_state : normal state : streaming sender_sent_location : 0/40002e8 sender_write_location : 0/40002e8 sender_flush_location : 0/40002e8 sender_replay_location : 0/40002e8 receiver_received_location : 0/40002e8 receiver_write_location : 0/40002e8 receiver_flush_location : 0/40002e8 receiver_replay_location : 0/40002e8 sync_percent : 100% sync_state : sync sync_priority : 1 sync_most_available : on channel : 172.11.0.101:5434-->172.11.0.102:35454 receiver info: no information
