许多文档介绍到这里，下一步为挂载/cgroup文件系统，我的docker版本为1.1.2，没有修改/etc/fstab的步骤。
5. 启动试运行
复制代码
# service docker start
//或
# docker -d
6. 以守护模式运行docker.io（在一个新的终端里）
复制代码
[root@localhost ~]# docker -d
2013/08/21 07:47:07 WARNING: Your kernel does not support cgroup swap limit.
2013/08/21 07:47:07 Listening for HTTP on /var/run/docker.sock (unix)
7. 在centos6.4容器里输出hello world
复制代码
[root@localhost ~]# docker run centos:6.4 echo "hello world"
