一、创库授权

　　1.1.、（控制节点）配置数据库 

mysql -u root -pADMIN_PASS

　　1.2、创建数据库并配置权限

CREATE DATABASE neutron;

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'ADMIN_PASS';

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'ADMIN_PASS';

　　1.3、控制节点）创建认证信息 

openstack user create --domain default --password ADMIN_PASS neutron

openstack role add --project service --user neutron admin

openstack service create --name neutron --description "OpenStack Networking" network

openstack endpoint create --region RegionOne network public http://controller:9696

openstack endpoint create --region RegionOne network internal http://controller:9696

openstack endpoint create --region RegionOne network admin http://controller:9696

二、安装服务

　　1.1、（控制节点）安装软件包并配置配置文件 

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

　　1.2、编辑/etc/neutron/neutron.conf文件并配置如下项

grep '^[a-z\[]' /etc/neutron/plugins/ml2/ml2_conf.ini.bak >/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
...

[ml2_type_flat]
flat_networks = provider
...

[ml2_type_vxlan]
vni_ranges = 1:1000
...

[securitygroup]
enable_ipset = true

　　1.4、编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件配置linux bridge插件

cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}
grep '^[a-z\[]' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak >/etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]
physical_interface_mappings = provider:ens34   #第二张网卡网卡名
...

[vxlan]
enable_vxlan = true
local_ip = 10.0.0.11
l2_population = true
...

[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

　　1.5、确认内核支持网桥filters并作如下设置，编辑/etc/sysctl.conf增加以下内容

/etc/sysctl.conf

net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1

　　1.6、载入br_netfilter模块

modprobe br_netfilter

　　从配置文件加载内核参数

sysctl -p

　　1.7、编辑/etc/neutron/l3_agent.ini配置三层插件

/etc/neutron/l3_agent.ini

[DEFAULT]
interface_driver = linuxbridge

　　1.8、编辑/etc/neutron/dhcp_agent.ini配置dhcp插件

/etc/neutron/dhcp_agent.ini

[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = true

　　1.9、编辑/etc/neutron/metadata_agent.ini文件配置metadata插件

/etc/neutron/metadata_agent.ini

[DEFAULT]
nova_metadata_host = controller
metadata_proxy_shared_secret = ADMIN_PASS

　　2.0、编辑文件/etc/nova/nova.conf配置计算服务使用网络服务

/etc/nova/nova.conf

[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default

grep '^[a-z\[]' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak >/etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:ens34  #第二张网卡名
...
[vxlan]
enable_vxlan = true
local_ip = 10.0.0.31
l2_population = true
...

[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

　　1.4、确认内核支持网桥filters并作如下设置，编辑/etc/sysctl.conf增加以下内容
