1. 安装组件

[root@compute01 ~]# yum install openstack-neutron-linuxbridge ebtables ipset -y

2. 修改配置文件

（1）修改neutron主配置文件

[root@compute01 ~]# cp -a /etc/neutron/neutron.conf{,.bak}
[root@compute01 ~]# grep -Ev '^$|#' /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf

openstack-config --set  /etc/neutron/neutron.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@controller
openstack-config --set  /etc/neutron/neutron.conf DEFAULT auth_strategy keystone 
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken auth_type password
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken project_domain_name default
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken user_domain_name default
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken project_name service
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken username neutron
openstack-config --set  /etc/neutron/neutron.conf keystone_authtoken password NEUTRON_PASS 
openstack-config --set  /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

（2）配置Linux网桥代理

[root@compute01 ~]# cp -a /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}
[root@compute01 ~]# grep -Ev '^$|#' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak > /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[root@compute01 ~]# openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings  provider:eth0
[root@compute01 ~]# openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan  false
[root@compute01 ~]# openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group  true
[root@compute01 ~]# openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver  neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

（3）sysctl.conf

[root@compute01 ~]# echo 'net.bridge.bridge-nf-call-iptables=1
> net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf

[root@compute01 ~]# modprobe br_netfilter

[root@compute01 ~]# sysctl -p
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1

3. 修改nova配置文件{compute01}

openstack-config --set  /etc/nova/nova.conf neutron auth_url http://controller:5000
openstack-config --set  /etc/nova/nova.conf neutron auth_type password
openstack-config --set  /etc/nova/nova.conf neutron project_domain_name default
openstack-config --set  /etc/nova/nova.conf neutron user_domain_name default
openstack-config --set  /etc/nova/nova.conf neutron region_name RegionOne
openstack-config --set  /etc/nova/nova.conf neutron project_name service
openstack-config --set  /etc/nova/nova.conf neutron username neutron
openstack-config --set  /etc/nova/nova.conf neutron password NEUTRON_PASS

4. 重启nova计算服务

systemctl restart openstack-nova-compute.service

5. 启动neutron服务和设置开机自启动

systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

至此，计算节点上面的neutron服务安装完毕，下面切换到控制节点，验证整个neutron的安装。
验证整个neutron服务

6. 在控制节点（controller）执行以下命令验证neutron服务

[root@controller ~]# openstack extension list --network

[root@controller ~]# openstack network agent list

一定要确保列表中有4条记录，并且Alive状态为笑脸:-)，State为UP。
