一、環(huán)境檢查及Docker配置
本文采用redhat7.9作為測試環(huán)境，虛擬機(jī)安裝操作系統(tǒng)的步驟不再列出。
官方的docker鏡像要求主機(jī)資源至少為2C10G。本機(jī)主機(jī)資源配置（4c16G，磁盤100G）

1.1 安裝docker
#內(nèi)核版本不低于3.10。
uname -a#設(shè)置docker源倉庫
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#安裝docker
yum install -y docker-ce docker-ce-cli containerd.io#啟動docker服務(wù)
systemctl start docker
#激活docker服務(wù)開機(jī)自啟動
systemctl enable docker.service#校驗(yàn)
[root@rac04 ~]# docker version

1.2 配置docker鏡像源
國內(nèi)從 DockerHub 拉取鏡像有時會遇到困難，此時可以配置鏡像加速器。Docker 官方和國內(nèi)很多云服務(wù)商都提供了國內(nèi)加速器服務(wù)，參考Docker Hub 鏡像源 - 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"]
}#重啟docker服務(wù)
systemctl restart docker.service #校驗(yàn)鏡像源
[root@rac04 ~]# docker info |grep Mirrors -A 5Registry Mirrors:https://dockerproxy.com/https://hub-mirror.c.163.com/https://mirror.baidubce.com/https://ccr.ccs.tencentyun.com/Live Restore Enabled: false
二、OB鏡像下載
下載地址：https://hub.docker.com/r/oceanbase/oceanbase-ce/tags，該地址可能需要使用代理訪問。這里直接貼出來docker pull oceanbase/oceanbase-ce:3.1.3
找到3.1.3版本，復(fù)制拉取命令
[root@rac04 ~]# docker pull oceanbase/oceanbase-ce:3.1.3
