這段時間由於測試需要搭建openstack環境，搜遍谷歌百度進行不下30次嘗試...看了陳沙克等前輩的安裝教程，很多配置資訊都已經過期了。不過大致的步驟基本不變，由於最近devstack在github更新頻繁，可能很多功能被新增更新，源軟體連結可能需要更改。下面給出這段時間安裝的步驟（附最新源），希望對有需要進行一鍵部署openstack測試環境的朋友有幫助。

測試版本：Ubuntu 12.04.5 LTS

系統核心：Linux r10f17332.sqa.zmf 3.2.0-60-generic #91-Ubuntu SMP x86_64 x86_64 

更換163源

cd  /etc/apt
cp sources.list etc-apt-source.list
vim sources.list
 

把源樣本儲存在etc-apt-source.list後清空sources.list並新增163源

deb http://mirrors.163.com/ubuntu/ precise main restricted
deb-src http://mirrors.163.com/ubuntu/ precise main restricted

deb-src http://mirrors.163.com/ubuntu/ precise-security multiverse
deb http://extras.ubuntu.com/ubuntu precise main
deb-src http://extras.ubuntu.com/ubuntu precise main

如果遇到如下報錯：

W: GPG error: http://extras.ubuntu.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192

執行以下命令解決：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192

更新系統源並更新系統

sudo apt-get update
sudo apt-get upgrade
 

安裝git工具 【已經安裝跳過此步驟】

apt-get install git

設定pip源 【該源經過測試，目前好用】

mkdir ~/.pip
cd ~/.pip
touch pip.cnf
vim pip.cnf

下載devstack 【使用者目錄】

cd /home/xxx
git clone https://github.com/openstack-dev/devstack.git

執行./stack.sh

只能使用非root使用者（這裡我以xxx為例）執行該指令碼

cd /home/xxx/devstack
./stack.sh

安裝過程請保持良好的網路狀態，整個過程大概需要20分鐘，安裝完畢後會一下提示

This is your host IP address：x.x.x.x

Hroizon is now available at https://x.x.x.x/

Keystone is serving at http://x.x.x.x:5000/

The default users are:admin and demo

The password:<之前你輸入的密碼>

至此，整個安裝 過程就結束了。

訪問host IP，顯示頁面如下

使用管理員賬號進行登入進入主介面

過程中可能會進行的一些操作
