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. OpenStack 基本概念 介绍: https://www.openstack.org/software/ Compute管理员手册(必看):http://docs.openstack.org/trunk/openstack-compute/admin/content/ch_getting-started-with-openstack.html OpenStack End User Guide(必看): http://docs.openstack.org/user-guide/content/ Network管理员手册:http://docs.openstack.org/folsom/openstack-network/admin/content/ Object

使用命令行管理openstack: http://docs.openstack.org/cli/quick-start/content/index.html OpenStack Wiki: https://wiki.openstack.org/wiki/Main_Page 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。
