#yum -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables

#vi /etc/neutron/neutron.conf

在 [database] 部分，配置数据库访问：
connection = mysql+pymysql://neutron:000000@controller/neutron

在``[DEFAULT]``部分，添加如下内容
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
rpc_backend = rabbit
auth_strategy = keystone
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True

在[oslo_messaging_rabbit]部分，配置 “RabbitMQ” 消息队列的连接：
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 000000

在[keystone_authtoken]部分，配置认证服务访问
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = 000000

在[nova]部分，配置网络服务来通知计算节点的网络拓扑变化：
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = 000000

在 [oslo_concurrency] 部分，配置锁路径：
lock_path = /var/lib/neutron/tmp

#vi /etc/neutron/plugins/ml2/ml2_conf.ini
在[ml2]下添加
type_drivers = flat,vlan,vxlan,gre,local
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security

在 [ml2_type_flat] 部分，配置公共虚拟网络为flat网络
flat_networks = provider

在 [ml2_type_vxlan] 部分，为私有网络配置VXLAN网络识别的网络范围：
vni_ranges = 1:1000

在 [securitygroup] 部分，启用 ipset 增加安全组规则的高效性：
enable_ipset = True

#vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini

在 [linux_bridge] 部分，将公共虚拟网络和公共物理网络接口对应起来：
physical_interface_mappings = provider:eth1 
#注意，此处的eth1为基础环境配置中的200的网段 也就是  192.168.200.0/24

在 [vxlan] 部分，启用VXLAN覆盖网络，配置覆盖网络的物理网络接口的IP地址，启用layer－2 population：
enable_vxlan = True
local_ip = 192.168.100.10   #这里的IP地址是controller的管理网络
l2_population = True

在  [securitygroup] 部分，启用安全组并配置 Linuxbridge iptables firewall driver:
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

#vi /etc/neutron/l3_agent.ini

在[DEFAULT]下添加
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge =

#vi /etc/neutron/dhcp_agent.ini

在[DEFAULT]下添加
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True

#vi /etc/neutron/metadata_agent.ini
在``[DEFAULT]`` 部分，配置元数据主机以及共享密码：
nova_metadata_ip = controller
metadata_proxy_shared_secret = 000000

#vi /etc/nova/nova.conf
在``[neutron]``部分，配置访问参数，启用元数据代理并设置密码：
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = 000000
service_metadata_proxy = True
metadata_proxy_shared_secret = 000000

# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

# systemctl restart openstack-nova-api.service

# yum -y install openstack-neutron-linuxbridge ebtables ipset

#vi /etc/neutron/neutron.conf

rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 000000

在[keystone_authtoken]下添加
