一、前言

OpenStack是一个开源的云计算管理平台项目，OpenStack支持几乎所有类型的云环境，项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务（IaaS）的解决方案，每个服务提供API以进行集成。OpenStack覆盖了网络、虚拟化、操作系统、服务器等各个方面。

二、安装方式

openstack安装方法有很多种，其中有手动一步一步安装，fuel安装，devstack安装，rdo安装，RDO是红帽的的一个开源项目，能够帮我们快速部署openstack开发环境，官方部署文档：https://www.rdoproject.org/install/packstack/

三、测试环境

环境使用vmware进行测试，内存8G，处理器为4，磁盘200G，2块网卡，一块为net，一块为仅主机模式。开启支持虚拟化

三、基本配置

配置net网卡与仅主机网卡，配置完成后可以连接外网

vi /etc/sysconfig/network-scripts/ifcfg-ens33

vi /etc/sysconfig/network-scripts/ifcfg-ens34

重启网卡

service network restart

完成后即可ping通外网，

修改主机名，关闭防火墙，selinux

hostnamectl set-hostname  rdo-openstack

 重启

reboot

四、安装，

安装过程非常简单，只有4条命令，顺序执行即可

sudo yum install -y centos-release-openstack-rocky

sudo yum update -y

sudo yum install -y openstack-packstack

sudo packstack –allinone

完成后将会输出以下内容
