1、安装服务
# yum install openvswitch openstack-neutron-openvswitch ebtables ipset -y

2、修改配置文件/etc/neutron/neutron.conf
# cd /etc/neutron/ && mv neutron.conf neutron.conf.source && cat neutron.conf.source |grep -Ev "^#|^$" > neutron.conf && chown root:neutron neutron.conf
# vi /etc/neutron/neutron.conf
在【DEFAULT】部分中，配置RabbitMQ消息队列访问
[DEFAULT]
# ...
transport_url = rabbit://openstack:openstack@controller

在 [DEFAULT] and [keystone_authtoken] 部分中，配置 Identity service 访问权限
[DEFAULT]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron

在【oslo_concurrency】部分中，配置锁路径
[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp

3、修改配置文件/etc/neutron/plugins/ml2/openvswitch_agent.ini
# cd /etc/neutron/plugins/ml2 && mv openvswitch_agent.ini openvswitch_agent.ini.source && cat openvswitch_agent.ini.source |grep -Ev "^#|^$" > openvswitch_agent.ini  && chown root:neutron openvswitch_agent.ini
# vi /etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
 
[agent]
tunnel_types = vxlan
l2_population = True
 
[ovs]
tunnel_bridge = br-tun
local_ip = 172.16.10.101       #本机第二块网卡ip
bridge_mappings = 
 
[securitygroup]
firewall_driver = iptables_hybrid
enable_security_group = true
 
[xenapi]
 
4、修改配置文件/etc/nova/nova.conf
# vi /etc/nova/nova.conf
在【neutron】部分增加
[neutron]
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

5、重启nova-compute
# systemctl restart openstack-nova-compute.service

6、启动 neutron-openvswitch-agent 服务并设置开机自启动
# systemctl enable neutron-openvswitch-agent.service 
# systemctl start neutron-openvswitch-agent.service
# systemctl restart neutron-openvswitch-agent.service

7、验证Neutron
列出成功启动的Neutron代理
# openstack network agent list

查看网络
# openstack network list

查看子网
# openstack subnet list

查看网络接口
# openstack port list

删除网络

# openstack port delete ip-address=192.168.58.110
# openstack subnet delete subnet_192.168.58
# openstack network delete public

说明：删除网络前，要先后顺序删除，即先要删除子网下的网络接口-->删除子网-->删除网络
