使用Packstack工具一键安装OpenStack

1.环境规划

操作系统版本 硬件配置 IP地址规划 主机名 虚拟机软件 OpenStack版本
centos7.9 4vCPUS/15G 30G硬盘 172.17.2.60/24 openstack VMware WorkStation16 Stein

centos7.9镜像获取地址：http://mirrors.aliyun.com/centos/7.9.2009/isos/x86_64/CentOS-7-x86_64-Minimal-2009.iso

2.准备资料

OpenStack官方文档：https://docs.openstack.org/install-guide/

使用Packstack一键部署OpenStack的方式，隐藏了技术细节，如果使用中出来任何问题，我们都无法解决，所以体验完OpenStack的日常界面操作后，后期还是要仔细查看官方文档，然后一步步手工安装OpenStack各组件。
