1 ubuntu 完成安装docker 之后， 执行：
| $ sudo service docker start |
报错：
2 处理方法：
执行：
$ systemctl unmask docker.service $ systemctl unmask docker.socket $ systemctl start docker.service |
3 再执行：
$ sudo service docker start $ docker run hello-world |
成功！ latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
