neutron网络服务部署

控制节点执行
#第一步 登陆数据库
mysql -u root -p
#导入neutron这个库
CREATE DATABASE neutron;
#创建neutron这个用户和密码，并允许本地登陆和第三方登陆
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_DBPASS';
#退出
exit
#宣告环境变量
. admin-openrc
#第二步 创建neutron这个用户
openstack user create --domain default --password=neutron neutron
#把neutron这个用设置为管理员
openstack role add --project service --user neutron admin
#创建一个neutron网络服务
openstack service create --name neutron \
  --description "OpenStack Networking" network
#添加neutron服务的端点
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

•    Networking Option 2: Self-service networks
#第三步 下载neutron主服务，neutron-ml2插件
yum install openstack-neutron -y 
yum install openstack-neutron-ml2 -y
yum install ebtables –y
yum install openvswitch –y
yum install openstack-neutron-openvswitch -y
#编辑neutron主配置文件 
cd /etc/neutron

#第四步 创建软连接

#开启路由功能和设置开机自启
systemctl start neutron-l3-agent.service

#查看 openstack network agent list
#刷出来四项，都是up部署成功
