1 您需要了解
- 本篇为手工搭建第
4篇，进行OpenStack Placement组件安装 - 操作系统版本
CentOS Stream 8，最小化安装，可参考下方相关文章G003完成系统安装，步骤一致 - 安装源您可访问 CentOS官网 / 阿里永久镜像站 / 华为永久镜像站 或其他镜像站进行下载
- 环境用到
2台虚拟机，单网卡，并为其配置静态 IP及DNS，具体规划请参考第 2 章环境规划 - 从
Ussuri版本开始，需要使用CentOS 8或RHEL 8，截至发稿前，Stream 8 版本支持的最高版本为yoga - 文中用到的本地源文件，如有需要请站内私信获取，手工搭建流程参考官方安装指南
- 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 - 为有更好的浏览体验，您可以点击文章左上方

2 环境规划
计算节点必须开启虚拟化引擎 Intel VT-x 或 AMD-V。虚拟机配置可根据实际情况进行调整。
