在centos8中安装OpenStack--亲测能用，绝对可靠

建议虚拟机至少4U4G以上，条件允许的话，最好8G以上。

①设置主机名：hostnamectl set-hostname controller && /bin/bash

hostnamectl set-hostname controller && /bin/bash

②关闭防火墙：systemctl disable --now firewalld && systemctl status firewalld

systemctl disable --now firewalld && systemctl status firewalld

③关闭selinux：  临时关闭  ：setenforce 0&& sed -i 's/enforcing/disabled/' /etc/selinux/config && cat /etc/selinux/config
   永久关闭         vim /etc/sysconfig/selinux
                         SELINUX=disabled

setenforce 0&& sed -i 's/enforcing/disabled/' /etc/selinux/config && cat etc/selinux/config
vim /etc/sysconfig/selinux
SELINUX=disabled

 
④安装基础软件：

yum install -y vim net-tools bash-completion chrony.x86_64 centos-release-openstack-victoria.noarch network-scripts 

                        

 yum clean all && yum clean metadata && yum clean dbcache

⑤NTP同步：

yum install chrony.x86_64 -y

vim /etc/chrony.conf

vim /etc/chrony.conf
server ntp.aliyun.com iburst
allow 10.10.10.0/24     #自己的网段，不要照搬

 重启chronyd服务：systemctl enable chronyd --now && systemctl status chronyd

systemctl enable chronyd --now && systemctl status chronyd

⑥关闭networkmanager ：systemctl disable NetworkManager --now

systemctl disable NetworkManager --now

    开启network:  systemctl enable network --now  && systemctl status  network 

systemctl enable network --now  && systemctl status  network 

    #如果没有network，安装network-scripts: yum install -y network-scripts 
复制网卡配置文件并重启主机：

cd /etc/sysconfig/network-scripts/ &&  cp ifcfg-ens160 ifcfg-eth0 && reboot

    查看服务状态：systemctl status network && systemctl status NetworkManager

⑦安装 PackStack 工具 ： yum install -y openstack-packstack    #安装前配置yum源-->参考openstack.repo

yum install -y openstack-packstack 

   生成应答文件：packstack --gen-answer-file=111.txt

packstack --gen-answer-file=111.txt

   修改应答文件：vim 111.txt

97 CONFIG_COMPUTE_HOSTS=10.10.10.81,10.10.10.82  #单机填本机IP（默认就是本机IP），多机才填其他IP。
323 CONFIG_KEYSTONE_ADMIN_PW=Aa12345678.   
1169 CONFIG_PROVISION_DEMO=n 
60 CONFIG_HEAT_INSTALL=y 
909 CONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens160

⑧安装openstack：packstack --answer-file=111.txt  #-----此步骤等待时间较长，不要慌，快的话半个小时，慢的话一个小时。
   #或者使用packstack --allinone安装

packstack --answer-file=111.txt

⑨卸载

停止服务：for service in $(systemctl list-units --type=service | grep openstack | awk '{print $1}'); do systemctl stop $service; done

  for service in $(systemctl list-units --type=service | grep openstack | awk '{print $1}'); do systemctl stop $service; done

  卸载OpenStack：

sudo yum remove -y 'openstack-*' 'python-openstack*' 'neutron*'

  删除OpenStack： rm -rf /etc/nova/* && rm -rf /etc/neutron/* && rm -rf /etc/glance/*

rm -rf /etc/nova/* && rm -rf /etc/neutron/* && rm -rf /etc/glance/*
