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 public and 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：

/article/5700613.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/packstack

quickstart: 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）
