openstack-6-neutron-控制节点

OpenStack Networking（neutron），允许创建、插入接口设备，这些设备由其他的OpenStack服务管理。插件式的实现可以容纳不同的网络设备和软件，为OpenStack架构与部署提供了灵活性。

一 配置与安装
[[email protected] ~]# mysql -h 10.0.0.17 -uneutron –pneutron
MariaDB [(none)]> show databases;

[[email protected] ~]# openstack user create --domain default --password-prompt neutron

[[email protected] ~]# openstack role add --project service --user neutron admin
[[email protected] ~]# openstack service create --name neutron \

–description “OpenStack Networking” network

[[email protected] ~]# openstack endpoint create --region RegionOne network public http://10.0.0.17:9696
