我在ubuntu14.04 LTS 桌面版/服务器版都安装DevStack成功后，在这里记录下安装过程。
介绍下安装环境：
VMware Workstation Pro 12
ubuntu14.04 LTS 系统
安装前准备：
1、系统更换ubuntu源，我选择的源如下：
deb http://mirrors.yun-idc.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.yun-idc.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.yun-idc.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.yun-idc.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.yun-idc.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.yun-idc.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.yun-idc.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.yun-idc.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.yun-idc.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.yun-idc.com/ubuntu/ trusty-backports main restricted universe multiverse
2、ubuntu手动配置一个IP，便于在ubuntu系统重启后，DevStack能够使用。
3、ubuntu配置一张能够访问外网的网卡即可。
4、由于安装环境时会涉及到pip工具，需要把pip源的地址映射到国内：
[global]
timeout = 6000
index-url = http://pypi.douban.com/simple/
[install]
trusted-host = pypi.douban.com
安装步骤
配置pip源
root@ubuntu:/# mkdir /root/.pip
root@ubuntu:/# vi /root/.pip/pip.conf
[global]
timeout = 6000
index-url = http://pypi.douban.com/simple/
[install]
trusted-host = pypi.douban.com
下载DevStack
安装git工具并下载DevStack
root@ubuntu:/# sudo apt-get install git
root@ubuntu:/# cd /home
root@ubuntu:/# git clone http://git.trystack.cn/openstack-dev/devstack.git -b stable/mitaka
创建stack用户
在非root用户下创建stack
Devstack@ubuntu:~$ cd /home/devstack/tools/
Devstack@ubuntu:~$ sudo ./create-stack-user.sh
为stack用户授权
在root用户下
root@ubuntu:/# vi /etc/sudoers
#找到如下一行：
root ALL=(ALL:ALL) ALL
#添加stack授权：
stack ALL=(ALL:ALL) ALL
root@ubuntu:/# chown -R stack:stack /home/devstack
root@ubuntu:/# chown -R stack:stack /opt/stack
创建local.conf文件
进入/home/devstack目录下，新建并编辑local.conf文件
root@ubuntu:/# cd /home/devstack
root@ubuntu:/home/devstack# vi local.conf
在local.conf文件中添加如下内容（配置IP根据自身环境修改）：
[[local|localrc]]

以stack用户运行脚本安装DevStack:
root@ubuntu:/home/devstack# su stack
root@ubuntu:/home/devstack# ./stack.sh
经过如上配置，即可完成安装。
安装过程中会有相关报错。
错误：
解决方法如下：
运行指令：
python
import openstack
import pbr.version
print(pbr.version.VersionInfo('openstacksdk').version_string())
quit()
./unstack.sh
./clean.sh
./stack.sh
如图所示：
在/usr/local/lib/python2.7/dist-packages/openstack/session.py 第29行中修改“openstacksdk/%s” 为 “openstacksdk/0.8.1”后，重新安装。
