CentOS Stream 8 通过 Packstack 安装开源 OpenStack（Victoria版本）
第一章：环境准备
1.1 系统要求
| 主机名 | IP | 网关/DNS | CPU/内存 | 磁盘 | 角色 | 备注 |
|---|---|---|---|---|---|---|
| controller01 | 192.168.100.101 | 192.168.100.2 | 4C/8G | 100G | 控制/网络/计算节点 | 必须开启虚拟化引擎 |
| compute02 | 192.168.100.102 | 192.168.100.2 | 4C/8G | 100G | 计算节点 | 必须开启虚拟化引擎 |
1.2 网络配置
控制节点网络配置
[root@controller01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.101
NETMASK=255.255.255.0
GATEWAY=192.168.100.2

[root@compute02 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.102
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=192.168.100.21.3 安全配置
控制节点安全配置
# 关闭防火墙
[root@controller01 ~]# systemctl stop firewalld
[root@controller01 ~]# systemctl disable firewalld
# 关闭 Selinux
[root@controller01 ~]# setenforce 0
[root@controller01 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
# 关闭 NetworkManager
[root@controller01 ~]# systemctl stop NetworkManager
[root@controller01 ~]# systemctl disable NetworkManager计算节点安全配置
# 关闭防火墙
[root@compute02 ~]# systemctl stop firewalld
[root@compute02 ~]# systemctl disable firewalld
# 关闭 Selinux
[root@compute02 ~]# setenforce 0
[root@compute02 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
# 关闭 NetworkManager
[root@compute02 ~]# systemctl stop NetworkManager
[root@compute02 ~]# systemctl disable NetworkManager注意：CentOS 8 版本默认使用 NetworkManager 管理网络，NetworkManager 会和 OpenStack 网络组件产生冲突，从而导致告警或错误：
- Warning: NetworkManager is active on 192.168.100.101, 192.168.100.102. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
- 翻译：警告：NetworkManager在192.168.100.101,192.168.100.102上处于活动状态。OpenStack组网目前不支持启用Network Manager服务的系统。

[root@controller01 ~]# yum install -y openstack-packstack3.2 生成应答文件
[root@controller01 ~]# packstack -h |grep ans
--gen-answer-file=GEN_ANSWER_FILE
Generate a template of an answer file.
--validate-answer-file=VALIDATE_ANSWER_FILE
Check if answerfile contains unexpected options.
--answer-file=ANSWER_FILE
answerfile will also be generated and should be used
-o, --options Print details on options available in answer file(rst
Packstack a second time with the same answer file and
attribute where "y" means an account is disabled.
--manila-netapp-transport-type=MANILA_NETAPP_TRANSPORT_TYPE
The transport protocol used when communicating with
[root@controller01 ~]# packstack --gen-answer-file=response.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 methodor tenant networks

重要提示：注意设置参数
CONFIG_NEUTRON_OVN_BRIDGE_IFACES，OVN 会自动创建 br-ex 虚拟交换机并使 ens160 桥接到 br-ex 虚拟交换机上，未来云主机通过 br-ex 可以连通外部网络。

* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
* Warning: NetworkManager is active on 192.168.100.101, 192.168.100.102. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
* File /root/keystonerc_admin has been created on OpenStack client host 192.168.100.101. To use the command line tools you need to source the file.
* To access the OpenStack Dashboard browse to http://192.168.100.101/dashboard .

[root@controller01 ~]#第四章：安装验证与后续配置
4.1 登录验证
4.2 启用 network 服务
说明：因关闭 NetworkManager 服务，会导致节点重启后网络无法自动启用，也会导致 OpenStack 组件异常，所以启用 network 来替代 NetworkManager 服务。
