• 192.168.205.7: as Chrony, DNS and YUM Source server(为了安装更快，自建yum源）
• 192.168.205.147: as DataBase, install MariaDB, RabbitMQ, Memcached
• 192.168.205.167: as controller, install keystone, placement, nova, neutron, dashboard
• 192.168.205.187: as compute node, install neutron agent and nova agent注：所有操作系统默认停用firewalld,iptable为空,关闭selinux
• OS: centos 7 1810 with mini install for controller and SQL server
• OS: CentOS 7 1511 with mini install for compute node
• Openstack Minimal deployment for Stein
• mariadb-10.3.10注：其它未注明均为yum 安装
• 最小化安装openstack stein最新版本
• 安装完成后各组件正常运行
• 测试成功建立实列并运行
• 通过运行实列测试基本的网络功能1. 安装前的环境准备
2. 安装keystone
3. 安装glance镜像服务
4. 安装placement
5. 安装Nova on controller
6. 安装Nova on compute node
7. 安装Neutron on controller node
8. 安装Neutron on compute node
9. 安装dashboard
10. 验证测试安装的准备工作很重要，因为openstack服务非常多，服务之间的依赖关系紧密，合理的规划不会导至安装出现问题，否则会出现各种的问题。

#cat /etc/chrony.conf

同进DNS也做为转发服务器为yum提像安装软件eth0为管理和API的网络
#cat ifcfg-eth0
NAME="eth0"
DEVICE="eth0"
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.205.x
NETMASK=255.255.255.0
TYPE=Ethernet
eth2为租户tenant网络使用，不配IP，设置成none
#cat ifcfg-eth2
NAME="eth2"
DEVICE="eth2"
ONBOOT=yes
BOOTPROTO=none
eth3为外网安装yum源使用，使用nat方式，同时将dns设置为内网的dns: 192.168.205.7
#cat ifcfg-eth3
NAME="eth3"
DEVICE="eth3"
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.18.18.x
NETMASK=255.255.255.0
GATEWAY=172.18.18.2
DNS1=192.168.205.7
注：不要修改HWADDR和UUID安装源，首先启用extras packges，我使用原cenos安装时自带的源, 也可以启用aliyun或tinghua的extras源

# yum install rabbitmq-server# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service# rabbitmqctl add_user openstack openstack123# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
注：在vhost "/" ...中给用户 "openstack" 授权身份识别服务验证机制使用Memcached缓存令牌，Memcached通常运行在controller上，对于生产部署，我们建议启用防火墙、身份验证和加密的组合来保护它。
# yum install memcached python-memcached#vi /etc/sysconfi/memcached
