安装RockyLinux8.7
和常规的CentOS安装一样，只需要分区即可。
网络配置：
[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens32
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=eui64
NAME=ens32
UUID=3e99463a-3387-4b09-8e26-e758ee1ed7c1
DEVICE=ens32
ONBOOT=yes
IPADDR=192.168.9.160
PREFIX=24
GATEWAY=192.168.9.2
环境配置
1、设置主机名
hostnamectl set-hostname openstack
2、设置本地名称解析
[root@openstack ~]# echo "192.168.9.160 openstack" >> /etc/hosts
3、禁用SElinux、禁用的防火墙
[root@openstack ~]# setenforce 0
[root@openstack ~]# vi /etc/selinux/config
...
SELINUX=disabled #设置成这样
...
#禁用防火墙
[root@openstack ~]# systemctl stop firewalld
[root@openstack ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
4、设置网络，这个和CentOS不太一样了，需要注意RockyLinux8不在使用Network来管理网络了，而是更替为NetworkManager服务来管理网络了。
[root@openstack ~]# nmcli connection modify ens32 ipv4.method
auto disabled link-local manual shared #可以看到有很多网络模式去设置，有静态、动态、共享等等
#如下配置：
[root@openstack ~]# nmcli connection modify ens32 ipv4.method manual ipv4.addresses 192.168.9.160/24 ipv4.gateway 192.168.9.2 ipv4.dns 223.5.5.5 autoconnect yes
#是配置生效
[root@openstack ~]# nmcli connection up ens32
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)
但是还值得需要注意的是，openstack不允许使用NetworkManager，而是需要使用Network，所以我们还需要安装Network的服务。很搞笑吧，但是没办法！
[root@openstack ~]# dnf install -y network-scripts
#然后禁用掉NetworkManager服务
[root@openstack ~]# systemctl stop NetworkManager
[root@openstack ~]# systemctl disable NetworkManager
Removed /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Removed /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
#开启Network服务
[root@openstack ~]# systemctl restart network
[root@openstack ~]# systemctl enable network
5、升级OS
[root@openstack ~]# dnf -y update
[root@openstack ~]# reboot
6、升级完查看系统信息：
[root@openstack ~]# cat /etc/os-release
NAME="Rocky Linux"
VERSION="8.7 (Green Obsidian)"

ID_LIKE="rhel centos fedora"
VERSION_ID="8.7"

配置openstack Yoga Yum Reository
1、下载Yum库
第一种方法：
[root@openstack ~]# dnf search openstack
Last metadata expiration check: 0:11:00 ago on Mon 05 Dec 2022 06:50:19 AM EST.
================================================= Name & Summary Matched: openstack ==================================================
centos-release-openstack-train.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-ussuri.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-victoria.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-wallaby.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-xena.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-yoga.noarch : OpenStack from the CentOS Cloud SIG repo configs #搜索到了这个版本
[root@openstack ~]# dnf install -y centos-release-openstack-yoga.noarch #然后直接安装即可
第二种方法：
[root@openstack ~]# dnf -y install https://repos.fedorapeople.org/repos/openstack/openstack-yoga/rdo-release-yoga-1.el8.noarch.rpm
#查看已启动的库
[root@openstack ~]# dnf repolist
repo id repo name
appstream Rocky Linux 8 - AppStream
baseos Rocky Linux 8 - BaseOS
centos-advanced-virtualization CentOS-8 - Advanced Virtualization
centos-ceph-pacific CentOS-8 - Ceph Pacific
centos-nfv-openvswitch CentOS-8 - NFV OpenvSwitch
centos-openstack-yoga CentOS-8 - OpenStack yoga
centos-rabbitmq-38 CentOS-8 - RabbitMQ 38
extras
当然我们可以选择性的安装任意版本：
2、启用powertools库：
[root@openstack ~]# dnf config-manager --enable powertools
3、重建以下缓存
[root@openstack ~]# dnf clean all
[root@openstack ~]# dnf makecache
安装packstack软件包并生成应答文件
[root@openstack ~]# dnf install -y openstack-packstack
那么现在就可以安装openstack了：
[root@openstack ~]# packstack --allinon
但是实际上我们不会直接这样安装，我们会先生成一个应答文件然后自定义安装，这样才符合实际情况。
生成应答文件：
[root@openstack ~]# packstack --gen-answer-file /root/openstack-answer.txt
Packstack changed given value to required value /root/.ssh/id_rsa.pub
Additional information:
* Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS plugin. Geneve will be used as the encapsulation method for tenant networks
修改应答文件：有原文件内容修改为如下内容：
CONFIG_HEAT_INSTALL=y #安装heat模板服务
CONFIG_PROVISION_DEMO=n #我们不要提供的demo项目
CONFIG_KEYSTONE_ADMIN_PW=admin #设置登陆密码
CONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens32 #OVN端口映射，就是云主机连接外网时通过那块网卡进行数据包的转发
最后就可以安装openstack了
[root@openstack ~]# packstack --answer-file /root/openstack-answer.txt
Welcome to the Packstack setup utility
