全部节点，解压到/opt目录下
如下所示：
[root@controller ~]# ls
openstack_rocky.tar.gz
[root@controller ~]# tar -zxf openstack_rocky.tar.gz -C /opt/
[root@controller ~]# cd /opt/
[root@controller opt]# du -h

#controller节点
yum install chrony -y

systemctl restart chronyd.service
systemctl enable chronyd.service

#其他节点上配置
yum install chrony -y
vim /etc/chrony.conf

一键部署OpenStack
控制节点安装openstack-packstack工具
#安装openstack-packstack工具用于生成openstack应答文件（txt文本格式）
[root@controller ~]# yum install -y openstack-packstack
[root@controller ~]# packstack --gen-answer-file=openstack.txt
[root@controller ~]# ls
openstack_rocky.tar.gz openstack.txt
修改一键部署配置文件的内容
具体内容建议查询了解其他的配置含义和作用
[root@controller ~]# vim openstack.txt
41行：y-n #SWIFT是OpenStack的对象存储组件，默认是Y，在生产环境中一般是不装，所以改n
50行：y-n #不安装该服务
97行：10.0.1.120,10.0.1.130 #计算节点ip地址
817 ：physnet1 #flat网络这边要设置物理网卡名字
862 ：physnet1:br-ex #这边要设置物理网卡的名字
873：br-ex:eth0 #这边br-ex:eth0是网络节点的nat网卡，到时候安装完毕之后IP地址会漂到这个上
1185：y-n #DEMO是OpenStack联网下载一个测试镜像，这边没联网。说以改成n
还有一些网段需要修改以及密码这里使用sed正则表达式来全局修改
##更改密码（123456）
[root@controller ~]# sed -i -r 's/(.+_PW)=.+/\1=123456/' openstack.txt
##将主机ip修改为仅主机网络
sed -i -r 's/192.168.0.110/10.0.1.110/g' openstack.txt
#进行备份
egrep -v "^#|^$" openstack.txt >openstack.txt.bak1
[root@controller ~]# grep 'HOST=' openstack.txt
CONFIG_CONTROLLER_HOST=10.0.1.110
CONFIG_VCENTER_HOST=
CONFIG_STORAGE_HOST=10.0.1.110
CONFIG_SAHARA_HOST=10.0.1.110
CONFIG_AMQP_HOST=10.0.1.110
CONFIG_MARIADB_HOST=10.0.1.110
CONFIG_TEMPEST_HOST=
CONFIG_REDIS_HOST=10.0.1.110
使用下面的命令进行一键部署安装
#保证控制节点的仅主机网络网关打开
#在各个节点终端（可以多开几个窗口终端使用下面的命令查看日志信息）
[root@controller ~]# tail -f /var/log/messages
[root@computel01 ~]# tail -f /var/log/messages
[root@computel02 ~]# tail -f /var/log/messages
接下来就是耐心等待
[root@controller ~]# packstack --answer-file=openstack.txt
