基于开源软件的私有云计算平台构建

摘要

介绍了私有云的应用范围,讨论了自行开发、商业和开源解决方案各自的特点,分析了开源方案的主要优势,比较了主流的开源云计算项目Eucalyptus、OpenStack、OpenNebula和Nimbus,重点研究了OpenStack架构.在此基础上,讨论了基于OpenStack的私有云计算平台构建方法,其主要过程包括基础环境配置,Nova、Glance、Swift、Keystone和Horizon组件安装,虚拟机部署等,最后给出了该平台在云计算软件测试项目中的应用实例.%This paper introduced the application range of the private cloud, discussed the characteristics of the self-developed and business and open source solutions, and analyzed the main advantage of the open source solution, then compared the mainstream projects of the open source cloud computing, such as Eucalyptus, OpenStack, OpenNebula and Nimbus, studied the structure of OpenStack mainly. Based on this, this paper presented the construction example of private cloud computing platform based on OpenStack, which major processes included configuration of base environment, components installation of Nova, Glance, Swift, Keystone and Horizon, deployment of virtual machines, and finally discussed the platform application examples in the cloud computing software testing.
