准备工作

1.1 取消selinux，因为它会干扰lxc的正常功能

sudo vim /etc/selinux/config
SELINUX=disabled
SELINUXTYPE=targeted
1.2 安装 Fedora EPEL
sudo yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
1.3 添加 hop5 repo地址
cd /etc/yum.repos.d
sudo wget http://www.hop5.in/yum/el6/hop5.repo

安装开始

$ sudo yum install docker-io

Now that it's installed, let's start the Docker daemon.

$ sudo service docker start

If we want Docker to start at boot, we should also:

$ sudo chkconfig docker on

Now let's verify that Docker is working. First we'll need to get the latest centos image.

$ sudo docker pull centos:latest

Next we'll make sure that we can see the image by running:

$ sudo docker images centos

This should generate some output similar to:

$ sudo docker images centosREPOSITORY      TAG             IMAGE ID          CREATED             VIRTUAL SIZEcentos          latest          0b443ba03958      2 hours ago         297.6 MB

Run a simple bash shell to test the image:

$ sudo docker run -i -t centos /bin/bash

If everything is working properly, you'll get a simple bash prompt. Type exit to continue.
