CentOS8最小化安装部署OpenStack私有云平台（Ussuri）

最近因为要做一个毕业作业，因为是云计算班，所以任务是搭建一个私有云平台，我首先想到的就是OpenStack，以为以前学习过先电的私有云平台，所以感觉应该挺容易的，但是真正上手，可真的是把我搞得一团懵，我整整搭建了3个日夜。

因为OpenStack更新较快，一个版本你还没学透彻，新版本就已经出来了，而且安装步骤等一些东西都会改变，这几天上网查阅了很多资料，绝大部分都已经不好用了，或者是根本就缺少东西，根本安装不上。

经过我苦苦的寻找，终于找到了一位大神的安装脚本，经过测试，安装成功，今天来分享给大家：

#Centos8最小化部署安装OpenStack Ussuri
#共两台主机，分别是一台控制节点，一台计算节点
#1、控制节点内存4096M。双网卡，分别为eth0:10.0.0.11，eth1:10.0.0.12
#2、计算节点内存2048M。双网卡，分别为eth0:10.0.0.31，eth1:10.0.0.32

#安装完成，可访问http://10.0.0.11/dashboard/查看

看好注释，一条条执行即可安装成功，如果有能力，可以将其拆分为两个脚本，在controller和compute节点执行即可成功安装。

如果报错，看看报错信息，相信你一定能解决的，晚安！

注意：

使用centos8系统！！！
