node1和node2
以node1为例、更改hosts文件和网络配置文件
[root@node1 ~]# vim /etc/hosts
192.168.37.248 openstack.123.net <--修改此行、把之前的'192.168.37.101'改为'192.168.37.248'
[root@node1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DNS1=192.168.37.2 <--
#重启网络、使用DNS生效
[root@node1 ~]# systemctl restart network
重启服务
[root@node1 ~]# bash scripts/nova-restart_agent.sh scripts/neutron-restart_agent.sh
ha1
修改'haproxy'配置文件
[root@ha1 ~]# vim /etc/haproxy/haproxy.cfg
#在'defaults'中把超时时长设置一下
53 timeout connect 120s
54 timeout client 600m
55 timeout server 600m

[root@controller2 ~]# yum install openstack-dashboard -y
controller1
拷贝到102
[root@controller1 ~]# scp /etc/openstack-dashboard/local_settings 192.168.37.102:/etc/openstack-dashboard/
controller2
过滤一下（检查配置文件中是否有IP地址需要修改）
[root@controller2 ~]# grep 192.* /etc/openstack-dashboard/* -R
/etc/openstack-dashboard/local_settings:OPENSTACK_HOST = "192.168.37.101"
/etc/openstack-dashboard/local_settings:# 'ipv4': ['10.0.0.0/8', '192.168.0.0/16'],
[root@controller2 ~]# vim /etc/openstack-dashboard/local_settings
OPENSTACK_HOST = "192.168.37.102" <--修改IP地址
重启服务
[root@controller2 ~]# systemctl restart httpd
Windows
修改hosts文件
浏览器
再创建几个虚拟机
添加规则
XShell连接
只有'102'能ping通
拷贝虚拟机
此时：内存不足可以切换到demo用户把实例删除（步骤忽略）
管理员：创建实例类型（1C-1G-20G）
创建实例
可ping通外网
