##6.1 Neutron控制节点

 

##6.1 Neutron控制节点
#6.1.Neutron.controller.sh

#本实例网络配置方式是：公共网络
#官方参考 https://docs.openstack.org/neutron/pike/install/controller-install-rdo.html

#创建Neutron数据库、用户认证，前面已设置

source ./admin-openstack.sh 
# 创建Neutron服务实体,API端点
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

#安装
yum install -y openstack-neutron openstack-neutron-ml2  openstack-neutron-linuxbridge python-neutronclient ebtables ipset

#Neutron 备份配置
