OceanBase社区版单节点安装搭建（Docker）
OceanBase社区版单节点安装搭建（Docker）
一、环境检查及Docker配置
本文采用redhat7.9作为测试环境，虚拟机安装操作系统的步骤不再列出。
官方的docker镜像要求主机资源至少为2C10G。本机主机资源配置（4c16G，磁盘100G）
[root@rac04 ~]# lscpu CPU(s): 4 [root@rac04 ~]# free -m total used free shared buff/cache available Mem: 15866 981 14534 12 350 14606 Swap: 8063 0 8063 [root@rac04 ~]# df -h 文件系统 容量 已用 可用 已用% 挂载点 devtmpfs 7.8G 0 7.8G 0% /dev tmpfs 7.8G 0 7.8G 0% /dev/shm tmpfs 7.8G 13M 7.8G 1% /run tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/mapper/rhel-root 92G 4.2G 87G 5% / /dev/sda1 1014M 183M 832M 19% /boot tmpfs 1.6G 8.0K 1.6G 1% /run/user/42 tmpfs 1.6G 0 1.6G 0% /run/user/0- 1

1.1 安装docker
#内核版本不低于3.10。 uname -a #设置docker源仓库 yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo #安装docker yum install -y docker-ce docker-ce-cli containerd.io #启动docker服务 systemctl start docker #激活docker服务开机自启动 systemctl enable docker.service #校验 [root@rac04 ~]# docker version Client: Docker Engine - Community Version: 25.0.3 API version: 1.44 Go version: go1.21.6 Git commit: 4debf41 Built: Tue Feb 6 21:17:10 2024 OS/Arch: linux/amd64 Context: default Server: Docker Engine - Community Engine: Version: 25.0.3 API version: 1.44 (minimum version 1.24) Go version: go1.21.6 Git commit: f417435 Built: Tue Feb 6 21:16:08 2024 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.28 GitCommit: ae07eda36dd25f8a1b98dfbf587313b99c0190bb runc: Version: 1.1.12 GitCommit: v1.1.12-0-g51d5e94 docker-init: Version: 0.19.0 GitCommit: de40ad0- 1

1.2 配置docker镜像源
国内从 DockerHub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务，参考Docker Hub 镜像源 - 掘金 (juejin.cn)
vi /etc/docker/daemon.json { "registry-mirrors": [ "https://dockerproxy.com", "https://hub-mirror.c.163.com", "https://mirror.baidubce.com", "https://ccr.ccs.tencentyun.com" ] } #重启docker服务 systemctl restart docker.service #校验镜像源 [root@rac04 ~]# docker info |grep Mirrors -A 5 Registry Mirrors: https://dockerproxy.com/ https://hub-mirror.c.163.com/ https://mirror.baidubce.com/ https://ccr.ccs.tencentyun.com/ Live Restore Enabled: false- 1

二、OB镜像下载
下载地址：https://hub.docker.com/r/oceanbase/oceanbase-ce/tags，该地址可能需要使用代理访问。这里直接贴出来
docker pull oceanbase/oceanbase-ce:3.1.3找到3.1.3版本，复制拉取命令
[root@rac04 ~]# docker pull oceanbase/oceanbase-ce:3.1.3 3.1.3: Pulling from oceanbase/oceanbase-ce 13add961a70d: Pull complete 1cf396138e36: Pull complete de207e7387d3: Pull complete Digest: sha256:22c2d82e5e7223ee510b1c53400edd05e622d9a09bc33987bd85ce560bb0781a Status: Downloaded newer image for oceanbase/oceanbase-ce:3.1.3 docker.io/oceanbase/oceanbase-ce:3.1.3- 1

三、obd部署单节点数据库
运行docker容器
[root@rac04 ~]# docker run -d -m 12G --cpus 4 --name oceanbase-ce oceanbase/oceanbase-ce:3.1.3 61d0ccd3ea95e36938527701c07d85f89fe950921004c4b133302dd32051dc5c [root@rac04 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 61d0ccd3ea95 oceanbase/oceanbase-ce:3.1.3 "/bin/sh -c _boot" 8 seconds ago Up 8 seconds oceanbase-ce- 1

docker镜像已经部署好了一个集群——obcluster，这里不再部署。附上obd操作集群的常用命令
#启动集群 obd cluster start 集群名 #停止集群 obd cluster stop 集群名 #重启集群 obd cluster restart 集群名 #查看集群状况 obd cluster list obd cluster display 集群名 #查看集群配置,也可以根据模板，重新建一个配置文件，重新部署新集群 obd cluster edit-config 集群名- 1

四、创建业务租户、数据库、表
连接数据库，默认root密码为空
obclient -h127.0.0.1 -P2881 -uroot@sys -p -c -A -Doceanbase- 1
-- 修改root密码 alter user root identified by 'root';- 1
