centos 启动docker

准备centos操作系统，安装docker

    [root@localhost ~]# yum install docker

启动 docker 并将其设置为开机启动

    [root@localhost ~]# systemctl start docker
    [root@localhost ~]# systemctl enable docker

如果操作系统不支持systemctl 语法的话，可以用下面的方式启动

    [root@localhost ~]# service docker start
    [root@localhost ~]# chkconfig docker on

dockder 重启 停止

     [root@localhost ~]# service docker restart
     [root@localhost ~]# service docker stop
