openstack配置扁平网络（一个内网，一个外网，两个网卡）

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = public:eth0,internal:eth1

vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2_type_flat]
flat_networks = public,internal

systemctl restart neutron-server.service neutron-linuxbridge-agent.service

计算节点

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = public:eth0,internal:eth1

systemctl restart neutron-linuxbridge-agent.service

2. 在控制节点添加网络和子网

   openstack network create  --share --external --provider-physical-network internal --provider-network-type flat internal

openstack subnet create --network internal   --allocation-pool start=10.201.2.100,end=10.201.2.200   --dns-nameserver 202.96.134.133 --gateway 10.201.2.254   --subnet-range 10.201.2.0/24 internal

openstack network list
