1，关于网络规划部分,之前写的都好好的了,浏览器TM的崩溃了,我写几天的笔记 记录全给我丢了,我TM的多心疼啊!

大致说了关于openstack手动安装关于网络规划的问题

第一种legacy networking

　　architecture  design :controller(跑单网卡management) + N computerNodes(跑2块网management+虚机实例隧道口卡)

第二种 openstack networking (neutron)

　　architecture design :controller(跑单网卡 management)+ one networkNode(跑3块网卡management+虚机隧道口+外网口) +N nodes(2网络口,无外网口)

2,epel+rdo-release-icehouse openstack版本仓库

controller or computer (需安装MySQL-python)节点 openstack云组件

yum install yum-plugin-priorities
