[root@iZbp1gp1t778obaz5m8vk8Z ~]# yum -y install docker

[root@iZbp1gp1t778obaz5m8vk8Z ~]# service docker start

[root@izwz99z5o9dc90keftqhlrz ~]# docker run hello-world
 
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

# 其效果是在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp
