3 OpenStack 基础
The 5-minute Overview
OpenStack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for publicand private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement, massively scalable, and feature rich. The technology consists of a series of interrelated
projects delivering various components for a cloud infrastructure solution. OpenStackcontrols large
pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

简单安装 OpenStack
环境设置
为了快速安装OpenStack,你要设置最快的apt源(或者设置yum源)和pypi源。设置apt源:http://blog.ubuntusoft.com/ubuntu-update-source.html
设置pypi源:http://www.v2ex.com/t/75316
你也可以搭建自己的apt源和pypi源:
搭建apt源:

http://www.cnblogs.com/kulin/archive/2012/08/08/2628400.html
搭建pypi源:
https://pypi.python.org/pypi/bandersnatch
devstack 安装
使用devstack安装 http://devstack.org阅读devstack.sh脚本 http://devstack.org
screen的使用:http://www.9usb.net/201002/linux-screen-mingling.html
devstack使用screen管理OpenStack各个服务,所以你要用screen调试OpenStack。
packstack(RHEL,CentOS) 安装
git仓库: https://github.com/stackforge/packstackquickstart: http://openstack.redhat.com/Quickstart
deb包安装
使用VirtualBox安装OpenStack在Ubuntu
12.04上安装OpenStack Folsom版(FlatDHCP+Multihost)
Ubuntu12.04.2
OpenStack Grizzly 安装(Bridge)
源码安装
