注意
1.本教程为openstack 搭建平台victoria 版，虚拟机为centos stream 8
2.本教程设计内容非常多，很复杂，但也很有技巧，请注意每一步，我说可以更改的地方可以更改，其余建议和我一样
3.内容板块大体包括：基础环境设置， keystone组建安装，glance组建安装，placement组建安装，nova组建安装，neutron组建安装，dashboard组建安装
4.密码约定：本文所有和数据库及消息队列相关的密码统一设定 rootroot，openstack 组件用户密码统一设定 redhat
5.学习此章节，你需要了解的知识：数据库sql中dcl用户管理的知识，linux基础命令，openstack基础命令
6.官方网址：
OpenStack Docs: Install and configure Placement for Red Hat Enterprise Linux and CentOS
7.环境配置：
环境用到 2台 虚拟机，单网卡，并为其配置 静态 IP 及 DNS
| 主机名 | ip | 网关 | DNS | cpu/内存 | 磁盘 | 角色 | 备注 |
| controller | 192.168.100.128 | 192.168.100.2 | 114.114.114.114 | 4c/6g | 100g | 控制节点 | 开启虚拟化引擎 |
| compute | 192.168.100.129 | 192.168.100.2 | 114.114.114.114 | 4c/6g | 100g | 计算节点 | 开启虚拟化引擎 |
