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：

    • http://blog.ef.net/2012/10/26/unbutu-release-upgrade-with-local-apt-mirror.html

    • 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/packstack

  • quickstart: http://openstack.redhat.com/Quickstart

deb包安装

  • 使用VirtualBox安装OpenStack
