一、前言
OpenStack是一個開源的雲計算管理平台項目，OpenStack支持幾乎所有類型的雲環境，項目目標是提供實施簡單、可大規模擴展、豐富、標准統一的雲計算管理平台。OpenStack通過各種互補的服務提供了基礎設施即服務（IaaS）的解決方案，每個服務提供API以進行集成。OpenStack覆蓋了網絡、虛擬化、操作系統、服務器等各個方面。
二、安裝方式
openstack安裝方法有很多種，其中有手動一步一步安裝，fuel安裝，devstack安裝，rdo安裝，RDO是紅帽的的一個開源項目，能夠幫我們快速部署openstack開發環境，官方部署文檔：https://www.rdoproject.org/install/packstack/
三、測試環境
環境使用vmware進行測試，內存8G，處理器為4，磁盤200G，2塊網卡，一塊為net，一塊為僅主機模式。開啟支持虛擬化
三、基本配置
配置net網卡與僅主機網卡，配置完成后可以連接外網
vi /etc/sysconfig/network-scripts/ifcfg-ens33
vi /etc/sysconfig/network-scripts/ifcfg-ens34
重啟網卡
service network restart
完成后即可ping通外網，
修改主機名，關閉防火牆，selinux
hostnamectl set-hostname rdo-openstack
LANG=en_US.utf-8
LC_ALL=en_US.utf-8
配置hosts文件 vi /etc/hosts
192.168.62.10 rdo-openstack
重啟
reboot
四、安裝，
安裝過程非常簡單，只有4條命令，順序執行即可
sudo yum install -y centos-release-openstack-rocky
sudo yum update -y
sudo yum install -y openstack-packstack
sudo packstack --allinone
完成后將會輸出以下內容
