RDO快速部署OpenStack

1.RDO是什么

RDO是红帽Red Hat Enterprise Linux OpenStack Platform的社区版，类似RHEL和Fedora，RHEV和oVirt这样的关系。 说白了，就是红帽支持一个开源项目，让你帮他踩坑，得到成熟稳定的版本，红帽搞一个企业版赚钱。

这个就是红帽的商业模式，其实是多方受益的，用户有一个开源免费的软件工具使用，当然前期可能“坑”比较多，但是和红帽一起磨合，共同提高稳定性，比较典型的就是CentOS。红帽发行商业版，赚去服务费，对可靠性、稳定性、服务要更高要求的用户，就可以购买红帽的服务。

2.RDO准备解决什么问题

OpenStack的安装是一个难题，组件众多，非常麻烦。最早支持OS的是Ubuntu，所以在ubuntu上有方便快捷的OpenStack安装脚本。

OpenStack越来越重要，越来越被大家认可，所以红帽也推出了OpenStack的快捷安装部署项目，这个项目就是RDO。

RDO项目的原理是整合上游的OpenStack版本，然后根据红帽的系统做裁剪和定制，帮助用户进行选择，对用户来说，就是简单的几步，完成了OpenStack的部署。

如果手工部署OpenStack，可能需要好几天，使用RDO，就是几个命令，再加一两个小时的等待。当然，牺牲了灵活性，但是对最终用户来说，要的是简单部署，稳定使用。

3.RDO的快速安装，4步就可以搞定

yum update -y

yum install -y https://rdoproject.org/repos/rdo-release.rpm

yum install -y openstack-packstack

packstack --allinone

根据网速不同，等待2小时，就可以使用OpenStack了：

4.安装过程
