使用 devstack 腳本很簡單，安裝 git，然後下載 devstack 代碼到本地，運行 stack.sh 腳本依次設定 MySQL, RabbitMQ, OpenStack Dashboard 和Keystone 的密碼，密碼輸入後 stack.sh 腳本會自動開始安裝必要的軟件包和庫並下載最新的 OpenStack 及其組件代碼，整個過程自動完成無需干預
$ sudo apt-get update
$ sudo apt-get install git
$ git clonegit://github.com/openstack-dev/devstack.git
$ cd devstack/
創建localrc文件，內容如下：

NOVNCPROXY_URL="http://42.62.73.241:6080/vnc_auto.html" #42.62.73.241是你虛擬機的公網IP地址
執行安裝腳本
$ ./stack.sh
