第三步：安装docker

sudo yum install docker

第三步：启动并加入开机启动

sudo systemctl start docker
    sudo systemctl enable docker

第四步：验证是否安装成功：

> 命令：docker version：查看docker的版本号，包括客户端、服务端、依赖的Go等

第五步：配置镜像加速器  
以配置阿里云加速器为例，首先 登录阿里云（没有账号请先注册），搜索 **容器镜像服务**

修改daemon配置文件/etc/docker/daemon.json，使其内容如下所示：

{ 
      "registry-mirrors": ["https://8kppz1zc.mirror.aliyuncs.com"]
    }

然后重启docker：

sudo systemctl daemon-reload
    sudo systemctl restart docker

第六步：验证

*  验证加速器是否正确：

 *  查看Docker 默认的位置： /var/lib/docker
