1.卸载

yum remove docker* -y

2.下载脚本

curl -fsSL https://get.docker.com -o install-docker.sh

3.安装指定版本

sh install-docker.sh --version 20.10.22

4.设置开机启动

systemctl start docker
systemctl enable docker
systemctl status docker

国内镜像源安装

第三步改为

sh install-docker.sh --mirror Aliyun --version 20.10.22

如果系统是centos steam 8再执行上一步

yum remove podman -y
yum remove buildah -y
yum install runc -y

不然可能报

[root@localhost ~]# sh install-docker.sh --mirror Aliyun --version 20.10.22
