基于CentOS 6.8的OpenStack手动安装-环境配置

前端之家收集整理的这篇文章主要介绍了基于CentOS 6.8的OpenStack手动安装-环境配置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。

1 环境

1.1 主机网络

wKioL1ds6viTm_PDAAFFK0mywn4215.png

1.1.1 系统的架构

1)节点分为控制节点、计算节点、块存储节点、对象存储节点

2)所有管理网络(10.168.0.0/24)和虚拟网络都使用私网地址连接共有网络(互联网203.0.113.x/8)

3)物理网络与虚拟网络(非10.168.0.0/24段)应当处于不同的网段

4)本架构NAT中的网关地址为10.168.0.1

5)物理节点使用NAT保持时间同步

1.1.2 部署信息

1)控制节点

hostname=rodm.cmdschool.org

ip address=10.168.0.125

OS=CentOS 6.8

2)计算节点

hostname=rod0[1-2].cmdschool.org

ip address=10.168.0.[126-127]

OS=CentOS 6.8

1.1.3 名称服务(可选)

1

vim /etc/hosts

输入如下信息:

1

2

3

10.168.0.125 rodm.cmdschool.org

10.168.0.126 rod01.cmdschool.org

10.168.0.127 rod02.cmdschool.org

1.2 安全
