设置权限权限为可执行

chmod +x /etc/systemd/system/docker.service

常用命令

systemctl daemon-reload   //重载配置文件
systemctl start docker    //启动Docker
systemctl stop docker    //关闭docker
systemctl restart  docker    //重启docker
systemctl enable docker.service   //设置开机自启
systemctl status docker    //查看Docker状态

很多时候在我们挂载磁盘后不想用docker默认目录可 -g 修改目录（docker 默认目录在/var/lib/docker下，包括 pull下来的镜像都在该目录下）

ExecStart修改为:

ExecStart=/usr/bin/dockerd -g /xiaobo/docker

修改后启动docker，路径已修改成功
