1. 下载docker的安装文件
   https://download.docker.com/linux/static/stable/x86_64/
2. 解压
   tar -zxvf docker-18.06.3-ce.tgz
3. 将解压出来的docker文件复制到 /usr/bin/ 目录下
   cp docker/* /usr/bin/
4. 进入/etc/systemd/system/目录,并创建docker.service文件

cd /etc/systemd/system/
touch docker.service

5. 打开docker.service文件,将以下内容复制
   注意：
   如果使用 ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=ip
   需要把 --insecure-registry=ip 此处改为你自己服务器ip
   insecure-registry 私有镜像 ip

   # the default is not to use systemd for cgroups because the delegate issues still
   # exists and systemd currently does not support the cgroup feature set required

6. 给docker.service文件添加执行权限
   chmod 777 /etc/systemd/system/docker.service

7. 重新加载配置文件（每次有修改docker.service文件时都要重新加载下）
   systemctl daemon-reload

8. 启动和设置开机启动
   systemctl start docker
systemctl enable docker.service

9. 查看 docker 状态
   systemctl status docker.service
