快速体验openstack-用devstack安装openstack
官网安装说明：--2014年11月15日14:14:21
安装环境：Ubuntu12.04，安装官网的说明遇到了小问题，记录在这里
--http://docs.openstack.org/developer/devstack/
--1
apt-get install git
--2
git clone https://git.openstack.org/openstack-dev/devstack
--3
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用户运行
run /opt/devstack/tools/create-stack-user.sh
--4
修改devstack目录权限,让stack用户可以运行
chown -R stack:stack /opt/*
切换的stack用户下
--5
修改ip
cp /opt/devstack/samples/local.conf /opt/devstack/
修改ip 为自己的ip
su stack,运行Devstack用stack用户运行的。
cd /opt/devstack
./stack.sh
--执行时间很长，出现这个错误=http://segmentfault.com/q/1010000000490204

解决办法:
将下面内容加到 ~/.pip/pip.conf 中
index-url=http://pypi.douban.com/simple
默认Devstack创建 admin和demo两个用户，通过设置环境变量可以进行操作
admin
source openrc admin admin
demo
source openrc demo demo
