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

环境配置

1、设置主机名

hostnamectl set-hostname openstack
1

2、设置本地名称解析

[root@openstack ~]# echo "192.168.9.160 openstack" >> /etc/hosts
1

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

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 ==================================================

[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

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
1

3、重建以下缓存

[root@openstack ~]# dnf clean all
[root@openstack ~]# dnf makecache 
1
2

安装packstack软件包并生成应答文件

[root@openstack ~]# dnf install -y openstack-packstack
1

那么现在就可以安装openstack了：

[root@openstack ~]# packstack --allinon
1

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

The installation log file is available at: /var/tmp/packstack/20221205-073938-j2xe350v/openstack-setup.log
#看提示，如果安装时那步出错，查看/var/tmp/packstack/20221205-073938-j2xe350v/openstack-setup.log日志文件
