os环境为： ubuntu14.04

安装步骤：

更新系统软件包：  sudo apt-get dist-upgrade    #出现无法访问到ubuntu官网的错误。
安装git： sudo apt-get install git
下载项目： git clone https://github.com/openstack-dev/devstack.git
切换命令： cd devstack
查看分支： git branch -a   #可以切换到不同的版本
切分支：   git checkout -b havana origin/stable/havana
把localrc拷贝到devstack下面，或者自己新建一个，把内容拷贝到里面：cp ~/Desktop/localrc ./
执行自动化部署：  ./stack.sh

这样安装的就是havana版本的openstack

配置文件：localrc
