注意点，整个过程中不能随便混合使用centos的源和redhat的源，否则会导致过程中出现各种问题
步骤1）节点名称修改
[root@localhost ~]# hostnamectl set-hostname “controller”
[root@localhost ~]# exec bash
[root@controller ~]# cat /etc/sysconfig/network
Created by anaconda
HOSTNAME=controller
在控制节点和计算节点修改配置文件 /etc/hosts，如下
[root@controller ~]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
10.2.5.142 controller
修改完节点名称后，reboot，使修改生效。
步骤2）禁用NetworkManager并使用network-scripts配置网络
Network-Manager是CentOS 8中用于管理网络的默认工具，但是对于Openstack，我们必须禁用它，因为Openstack网络无法与network-manager一起正常工作。为了替换NetworkManager，我们必须安装network-scripts。
要禁用network-manager，请运行以下命令，
[root@controller ~]# systemctl disable NetworkManager
[root@controller ~]# systemctl stop NetworkManager
运行以下dnf命令以安装network-scripts
[root@controller ~]# dnf install network-scripts y
一旦安装了network-scripts软件包，我们就可以使用本机network.service管理网络（ifcfg *文件）
[root@controller ~]# systemctl start network
[root@controller ~]# systemctl enable network
步骤3）设置语言环境变量
[root@controller yum.repos.d]# cat /etc/locale.conf
LANG=“en_US.UTF-8”
LC_CTYPE=“en_US.utf8”
LC_ALL=“en_US.UTF8”
[root@controller yum.repos.d]# source /etc/locale.conf
或者将上述环境变量添加至/etc/profile
步骤4）启用OpenStack repositories并安装packstack工具
在撰写本文时，victoria openstack已经稳定可用，因此请运行以下命令来配置其repositories(尽量不要随便安装repositories,否则可能出现各种问题)
安装前执行yum makecache提前解决缓存构建过程中出现的错误(个别源可能无法访问，需要删除)
[root@controller ~]# dnf config-manager --enable powertools
[root@controller ~]# dnf install -y centos-release-openstack-victoria
[root@controller ~]# dnf install -y openstack-packstack
步骤5）关闭防火墙
systemctl disable firewalld
systemctl stop firewalld
setenforce 0
步骤6）设置免密登陆
ssh-keygen
ssh-copy-id 10.2.5.142
步骤7）生成答案文件并使用packstack安装openstack
使用packstack命令生成应答文件，
[root@controller ~]# packstack --gen-answer-file /root/openstack-answer.txt
生成应答文件后，使用vim编辑器编辑内容以下参数(建议关于密码问题全部修改为简单秘密，方便部署成功)
CONFIG_CEILOMETER_INSTALL=n
CONFIG_MARIADB_PW=admin
CONFIG_KEYSTONE_DB_PW=admin
CONFIG_KEYSTONE_ADMIN_PW=admin

CONFIG_GNOCCHI_KS_PW=PW_PLACEHOLDER
CONFIG_CEILOMETER_KS_PW=PW_PLACEHOLDER
CONFIG_AODH_KS_PW=PW_PLACEHOLDER
CONFIG_AODH_DB_PW=PW_PLACEHOLDER
步骤8）部署
packstack -d --answer-file=/root/openstack-answer.txt
[root@controller ~]# packstack -d --answer-file=./answers.txt
