RDO快速部署OpenStack
1.RDO是什么
RDO是紅帽Red Hat Enterprise Linux OpenStack Platform的社區版，類似RHEL和Fedora，RHEV和oVirt這樣的關系。 說白了，就是紅帽支持一個開源項目，讓你幫他踩坑，得到成熟穩定的版本，紅帽搞一個企業版賺錢。
這個就是紅帽的商業模式，其實是多方受益的，用戶有一個開源免費的軟件工具使用，當然前期可能“坑”比較多，但是和紅帽一起磨合，共同提高穩定性，比較典型的就是CentOS。紅帽發行商業版，賺去服務費，對可靠性、穩定性、服務要更高要求的用戶，就可以購買紅帽的服務。
2.RDO准備解決什么問題
OpenStack的安裝是一個難題，組件眾多，非常麻煩。最早支持OS的是Ubuntu，所以在ubuntu上有方便快捷的OpenStack安裝腳本。
OpenStack越來越重要，越來越被大家認可，所以紅帽也推出了OpenStack的快捷安裝部署項目，這個項目就是RDO。
RDO項目的原理是整合上游的OpenStack版本，然后根據紅帽的系統做裁剪和定制，幫助用戶進行選擇，對用戶來說，就是簡單的幾步，完成了OpenStack的部署。
如果手工部署OpenStack，可能需要好幾天，使用RDO，就是幾個命令，再加一兩個小時的等待。當然，犧牲了靈活性，但是對最終用戶來說，要的是簡單部署，穩定使用。
3.RDO的快速安裝，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
根據網速不同，等待2小時，就可以使用OpenStack了：
