devstack 安装配置（安装部署开发测试环境）
废话不说，直接上步骤：
1、安装devstack
环境: 最好是物理机服务器
devstack 的安装不能直接用root 用户，新建一个用户stack
adduser -m stack passwd stack
从github上克隆devstack 的源码
su - stack git clone https://github.com/openstack-dev/devstack.git su - root cd /home/stack/devstack/tools/create-stack-user.sh
在/home/stack/devstack 目录中创建local.conf配置文件
[root@devstack-liberty devstack]# cat local.conf
[[local|localrc]]
# Define images to be automatically downloaded during the DevStack built process.

运行stack.sh 安装openstack
cd /home/stack/devstack ./stack.sh
整个过程大概需要一个小时，具体时间视各地网络速度而定
2、搭建开发环境（本地调试）
下载安装Eclipse
https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/luna/SR1/eclipse-java-luna-SR1-linux-gtk-x86_64.tar.gz
安装pydev 和egit 插件，如果需要前端，可以用aptana插件
http://pydev.org/updates
http://download.eclipse.org/egit/updates
安装完毕以后重启Eclipse
3、导入源码
导入源码之后需要设置成pydev项目:
4、远程调试
步骤:
Eclipse 配置端配置
1）. 添加 /opt/eclipse/plugins/org.python.pydev_3.8.0.201409251235/pysrc 被调试项目Python path 中（可选）
2）. 运行pydev debug
远程Keystone 服务器配置
3）. 拷贝Eclipse Dydev 插件下 pysrc 目录到 Keystone 机器上，并添加该目录到Python path
export PYTHONPATH=$PYTHONPATH:/opt/eclipse/plugins/org.python.pydev_3.8.0.201409251235/pysrc
4）. 在需要打断点的地方添加如下代码
import pysrc.pydevd as pydevd;pydevd.settrace('10.20.0.210',stdoutToServer=True, stderrToServer=True)
5）.单步调试
好处：支持线上,在线调试
本环境步骤:
在代码端配置好eclipse环境:
export PYTHONPATH=$PYTHONPATH:/root/eclipse/plugins/org.python.pydev_5.1.2.201606231256/pysrc
eclipse客户端打开pydev server
会监听5678端口
在需要调试的地方，代码端增加断点信息:
import pysrc.pydevd as pydevd;pydevd.pydevd.settrace('192.168.3.191',stdoutToServer=True, stderrToServer=True)
5、devstack服务器重启了，openstack服务是不会重启的，怎么办呢?
只好写脚本重启了
