openstack devstack 安装与配置
安装准备
OpenStack部署在Linux机器上。经过我的测试在Ubuntu 14.04 Server版上安装OpenStack Mitaka版本比较稳定。为了操作方便，我的Ubuntu是安装在VMware Workstation 12虚拟机上的。
Ubuntu 源可以替换为国内的阿里源。

虚拟机设置如图
下载DevStack
安装Git并下载最新版的devstack。
root@us14:~# apt-get install git
root@us14:~# cd /home
root@us14:~# git clone http://git.trystack.cn/openstack-dev/devstack.git -b stable/mitaka - 1

创建stack用户
目前DevStack脚本已经不支持直接使用root身份运行，你需要创建stack用户来运行。
在非root用户下创建stack用户并设置密码。
us14@us14:~$ sudo chown -R $USER:$USER /home/devstack
us14@us14:~$ cd /home/devstack/tools/
us14@us14:~$ sudo ./create-stack-user.sh
us14@us14:~$ sudo passwd stack- 1

在root用户下给stack用户授权。编辑/etc/sudoers，找到这一行 root ALL=(ALL:ALL) ALL，在下面加上一行 stack ALL=(ALL:ALL) ALL。
root@us14:~# vi /etc/sudoers
# User privilege specification
root ALL=(ALL:ALL) ALL
stack ALL=(ALL:ALL) ALL
root@us14:~# chown -R stack:stack /home/devstack
root@us14:~# chown -R stack:stack /opt/stack- 1

创建local.conf文件
进入/home/devstack目录，编辑local.conf文件(没有就新建)。
root@us14:~# cd /home/devstack/
root@us14:/home/devstack# vi local.conf- 1

在文件中添加如下内容。网络的地方需要根据自己的实际情况修改。
可以通过ifconfig命令查看自己的情况，我的如图

根据网络情况，安装速度有差别，等最后出现图中所示，则说明安装成功。
在安装的过程中可能遇到的问题：
一、
这个问题用sudo pip install python-openstackclient==2.3.1命令就可以解决
二、
