本次搭建才用双节点 由于本人是大三学生 电脑配置不够所以就才用双节点 我把网络节点部署在controller上
本次测试环境在vm下测试的 首先需要开启虚拟化
本次环境是centos7
内部网络 controller ：192.168.100.10 eth0
compute1：192.168.200.10 eth1
外部网络 controller：192.168.100.20 eth0
compute1：192.168.200.10 eth1
管理网络(内部网络)，用于OpenStack组件以及MysqL DB Server,RabbitMQ
messaging server之间的通信
外部网络：用于本机和实例通信
硬件基本配置：
控制节点: 1 processor,2 GB memory,and 5 GB storage
计算节点: 1 processor,and 10 GB storage
hosts配置：
#控制节点：
192.168.100.10 controller
# 计算节点
192.168.100.20 compute1
网络节点
外网网卡配置：
编辑/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME文件，完成下面内容
不要改变HWADDR 和 UUID keys.

检测网络互通性
1.从控制节点 ping外网
