卸载旧版

首先如果系统中已经存在旧的Docker，则先卸载：

 yum remove docker \
     docker-client \
     docker-client-latest \
     docker-common \
     docker-latest \
     docker-latest-logrotate \
     docker-logrotate \
     docker-engine

配置Docker的yum库

首先要安装一个yum工具

 yum install -y yum-utils

安装成功后，执行命令，配置Docker的yum源：

 yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装Docker

最后，执行命令，安装Docker

 yum install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

输入docker -v 说明安装成功

启动和校验

 # 启动Docker
 systemctl start docker
 # 停止Docker
 systemctl stop docker
 # 重启
 systemctl restart docker
 # 设置开机自启
 systemctl enable docker
 # 执行docker ps命令，如果不报错，说明安装启动成功
 docker ps

输入docker images，得到相应结果、无报错，说明docker启动成功
