本文主要是介绍14 龙芯平台openstack部署搭建-neutron-controllercomputer部署（单节点），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、创建neutron相关数据库、服务凭证和API端点
1.创建neutron数据库，授予合适的访问权限
mysql -uroot -ploongson -e “CREATE DATABASE neutron;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘%’ IDENTIFIED BY ‘loongson’;”
2.要创建服务凭证
#以下命令需要输入密码
openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin
openstack service create --name neutron --description “OpenStack Networking” network
3.创建网络服务 API 端点
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
openstack endpoint list
二、neutron相关软件安装与配置
#安装neutron相关软件
yum install -y openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables
#配置服务器组件
