title: How to install docker 1.9+ in CentOS 6.5?
body: <p>I'm now deploying on CentOS 6.5, and I'm now starting to use docker.</p>
  
  <p>So, I follow the instructions on: <a href="https://docs.docker.com/engine/installation/centos/" rel="noreferrer">https://docs.docker.com/engine/installation/centos/</a></p>
  
  <p>No matter which method I follow to install, I get version of <em>1.7.1</em>.</p>
  
  <pre><code>[root@VM_72_235_centos ~]# docker version
  Client version: 1.7.1
  Client API version: 1.19
  Go version (client): go1.4.2
  Git commit (client): 786b29d/1.7.1
  OS/Arch (client): linux/amd64
  Server version: 1.7.1
  Server API version: 1.19
  Go version (server): go1.4.2
  Git commit (server): 786b29d/1.7.1
  OS/Arch (server): linux/amd64
  </code></pre>
  
  <p>But now I run the command in the documentation:</p>
  
  <pre><code>docker network ls
  </code></pre>
  
  <p>With failure <code>docker: 'network' is not a docker command.</code>.</p>
  
  <p>And I finally know that the network action is first introduced in 1.9.</p>
  
  <p>So is there any way to install docker 1.9 in centos6 ?</p>
