一、base节点设置
mysql -u root -proot
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_DBPASS';
二、 ctrl节点设置
#运行环境变量
. admin-openrc
#创建neutron用户并添加角色
openstack user create --domain default --password NEUTRON_PASS neutron
openstack role add --project service --user neutron admin
#创建neutron服务并设置endpoint
openstack service create --name neutron --description "OpenStack Networking" network
openstack endpoint create --region RegionOne network public http://ctrl.test.com:9696
openstack endpoint create --region RegionOne network internal http://ctrl.test.com:9696
openstack endpoint create --region RegionOne network admin http://ctrl.test.com:9696
#安装neutron软件

#开启服务

systemctl enable neutron-linuxbridge-agent.service
注：配置文件中注释部分配置文件为创建L3路由网络使用的配置信息。未注释的配置信息为交换机网络。后续创建网络根据需要进行开启。注意，相同项保留一项即可。
