终端按顺序执行如下命令：

su root//切换为root账户

sudo env//下面使用root进行操作

boot2docker init//初始化虚拟机，包括虚拟机镜像下载

保证虚拟机电源开启

boot2docker up//把虚拟机打开

出现如下信息：

‘boot2docker’ the operating system) is officially deprecated.

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.

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
