openstack 入门 【准备篇】一:整体介绍【centos】 M版本

前端之家收集整理的这篇文章主要介绍了openstack 入门 【准备篇】一:整体介绍【centos】 M版本前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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.

2.从控制节点,ping计算节点管理网络
