Detailed tutorial on how to install OpenStack Ussuri in CentOS8 with minimal deployment

The tutorial for installing OpenStack Ussuri with minimal deployment on CentOS8 is as follows:

#!/bin/bash

#Centos8 Minimize the deployment and installation of OpenStack Ussuri
#There are two hosts, one control node and one computing node. #1. The control node has 4096M memory. Dual network cards, eth0:10.0.0.11, eth1:10.0.0.12
#2. Compute node memory: 2048 MB. Dual network cards, eth0:10.0.0.31, eth1:10.0.0.32
