一、环境需求
CentOS 7.6 系统
CPU：双核双线程/开启虚拟化功能
内存：4G
硬盘：30G+300G
网卡：NAT模式
选做：（装机界面按Tab键进入界面编辑，输入后面的内容）net.ifnames=0 biosdevname=0 (创建时可修改为eth0网卡）
二、环境配置
1、配置静态地址、主机名
vi /etc/sysconfig/network-scripts/ifcfg-eth0
......
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.50
NETMASK=255.255.255.0
GATEWAY=192.168.200.2
DNS1=192.168.200.2
DNS2=8.8.8.8
#在/etc/resolv.conf中添加：
vi /etc/resolv.conf
nameserver 114.114.114.114
#重启网卡
systmectl restart network
2、关闭（设置开机不启动）防火墙、核心防护、NetworkManager
systemctl stop firewalld
systemctl disable firewalld
systemctl stop NetworkManager
setenforce 0
3、安装时间同步服务、同步阿里云时钟服务器（ntp1、ntp2…)、设置周期性任务及设置开机自启
yum install -y ntpdate
ntpdate ntp.aliyun.com >>/var/log/ntpdate.log
crontab -e
....
4、配置yum源
[root@openstack ~]# cd /etc/yum.repos.d/
[root@openstack yum.repos.d]# mkdir bak
[root@openstack yum.repos.d]# mv C* bak/
[root@openstack yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@openstack yum.repos.d]# yum -y install centos-release-openstack-train
[root@openstack yum.repos.d]# yum clean all
[root@openstack yum.repos.d]# yum makecache (fast) #（）部分可选择添加
5、重启、查看服务状态
reboot
6、下载OpenStack 管理工具包、在线部署OpenStack
yum -y install openstack-packstack
packstack --allinone

#上传镜像，两种方式
第一种——命令行
openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public
第二种——控制台
#建议使用第一种
