1.1 取消selinux，因为它会干扰lxc的正常功能sudo vim /etc/selinux/config
$ 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
$ 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 centos REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE centos 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.
