#确认docker.....这一列有可用的包，我这里显示的是79个（多点少点没关系，但一定要有这一列，并且不能为0）
[root@docker ~]# yum install -y docker-ce-18.09.0-3.el7 docker-ce-cli-18.09.0-3.el7 containerd.io-1.2.0-3.el7            # yum安装docker

Success.
You need to restart docker to take effect: sudo systemctl restart docker 
[root@docker ~]# systemctl daemon-reload 
[root@docker ~]# systemctl restart docker
[root@docker ~]# systemctl enable docker
[root@docker ~]# cat /etc/docker/daemon.json              # 这个就是加速器相关的文件
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"]} 
[root@docker ~]# docker -v
Docker version 18.09.0, build 4d60db4
