硬件条件
双网卡、4核、8G
步骤1）节点名称修改
[root@controller ~]# hostnamectl set-hostname "controller"
[root@controller ~]# exec bash
[root@controller ~]# cat /etc/sysconfig/network
/# Created by anaconda
HOSTNAME=controller
[root@controller ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.2.5.157 controller
[root@controller ~]# ping controller
PING controller (10.2.5.157) 56(84) bytes of data.
64 bytes from controller (10.2.5.157): icmp_seq=1 ttl=64 time=0.089 ms
步骤2）设置免密登陆
[root@controller ~]# ssh-keygen
[root@controller ~]# ssh-copy-id 10.2.5.157
步骤3）禁用NetworkManager并使用network-scripts配置网络并重启
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。
[root@controller ~]# yum install -y network-scripts
[root@controller ~]# systemctl disable NetworkManager
[root@controller ~]# systemctl stop NetworkManager
[root@controller ~]# systemctl restart network
[root@controller ~]# systemctl enable network
[root@controller ~]# reboot
步骤4）关闭防火墙
[root@controller ~]# systemctl disable firewalld
[root@controller ~]# systemctl stop firewalld
[root@controller ~]# setenforce 0
步骤5）启用OpenStack repositories并安装packstack工具
[root@controller ~]# dnf config-manager --enable powertools
[root@controller ~]# yum install -y centos-release-openstack-ussuri
[root@controller ~]# yum install openstack-packstack
步骤6）生成答案文件并使用packstack安装openstack
使用packstack命令生成应答文件，并修改其中配置
[root@controller ~]# packstack --gen-answer-file /root/openstack-answer-u.txt
修改packstack --gen-answer-file /root/openstack-answer-u.txt中相关配置

步骤7）创建/share目录
[root@controller ~]# mkdir /share
步骤8）部署openstack
部署openstack-ussuri
[root@controller ~]# packstack -d --answer-file=/root/openstack-answer-u.txt
看到以下信息即部署成功
