OpenStack（五）使用Packstack工具一键安装OpenStack

一、环境规划

操作系统	虚拟机配置	IP地址	主机名	虚拟机软件	OpenStack版本
CentOS 7.9	4 CPU/8G 内存/30G 硬盘	192.168.0.31	openstack	VMware WorkStation 17	Stein

二、准备安装

从阿里源下载CentOS镜像或者用我已经从阿里源下载好的：

提取码：ekq5

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

三、开始部署

1.安装虚拟机

2.修改主机名

hostnamectl set-hostname openstack

3.修改IP地址

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

#修改以下2行
BOOTPROTO="static"
ONBOOT="yes"
#增加以下4行
IPADDR=192.168.0.31
PREFIX=24
GATEWAY=192.168.0.1
DNS1=192.168.0.1

systemctl restart network

4.添加本地解析

echo "192.168.0.31 openstack" >> /etc/hosts

5.设置本机SSH免密码登录

#生成ssh密钥

ssh-keygen

#添加密钥信息到~./ssh/know_hosts文件

ssh-copy-id root@192.168.0.31

6.关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

7.关闭SeLinux

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

8.关闭NetworkManager服务

systemctl stop NetworkManager
systemctl disable NetworkManager

9.配置yum源

参考阿里云yum源官方文档（https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11Jpkdzb）配置yum源，完成后还需要执行yum makecache;yum -y update;reboot。本文从阿里云下载的镜像已内置yum，无需操作。

10.安装常用软件

yum -y install vim bash-completion yum-utils

11.安装OpenStack Stein的yum库

yum -y install centos-release-openstack-stein

12.修改CentOS-OpenStack-stein.repo配置文件

cd /etc/yum.repos.d/
#备份
cp -a CentOS-OpenStack-stein.repo CentOS-OpenStack-stein.repo.bak

#修改配置文件
vim CentOS-OpenStack-stein.repo
[centos-openstack-stein]
baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/cloud/$basearch/openstack-stein/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cloud-openstack-stein
...

#清除本地yum索引缓存，然后再重建索引缓存
yum clean all && yum makecache

13.安装packstack工具

yum -y install openstack-packstack

14.安装OpenStack allinone

packstack --allinone

自动化安装时间很长,出现以下信息表示安装成功

 * The generated manifests are available at: /var/tmp/packstack/20230701-221352-iK5QeC/manifests

15.查看Dashboard web页面的登录账号及密码

cat keystonerc_admin 

unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin		#Dashboard登录账号
    export OS_PASSWORD='54d9192cab334d61'	#Dashboard登录密码
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://192.168.0.31:5000/v3
    export PS1='[\u@\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

16.Dashboard web登录界面

登录方式：http://192.168.0.31，账号admin，密码54d9192cab334d61

17.修改密码

使用新密码重新登录

为了后续实验过程，需要同时修改keystonerc_admin文件中的OS_PASSWORD变量，换成新密码

vim keystonerc_admin

export OS_PASSWORD='000000'	#填入修改后的新密码
