A16. openstack架构实战-添加一个flat网络
作者：互联网
1：给所有的节点都添加一个物理网卡：
2：给添加的网卡进行配置ip
3：测试ip是否正常可以ping通
修改网络配置：
控制节点修改：
增加flat网段类型：net203
[root@controller01 ~]# vim /etc/neutron/plugins/ml2/ml2_conf.ini
配置flat网络对应真实的物理网卡：
[root@controller01 ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
重启服务：
[root@controller01 ~]# systemctl restart neutron-server.service neutron-linuxbridge-agent.service
计算节点修改：
[root@compute01 ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini 
重启服务：
[root@compute01 ~]# systemctl restart neutron-linuxbridge-agent
[root@compute01 ~]# systemctl status neutron-linuxbridge-agent
测试：创建网络：
[root@controller01 ~]# openstack network create --external --share --provider-physical-network net203 --provider-network-type flat net203
[root@controller01 ~]# openstack network list

创建子网：
[root@controller01 ~]# openstack subnet create --network net203 --allocation-pool start=10.100.203.100,end=10.100.203.200 --dns-nameserver 114.114.114.114 --gateway 10.100.203.254 --subnet-range 10.100.203.0/24 net203-subnet
[root@controller01 ~]# openstack subnet list
