openstack 部署笔记--neutron控制节点
控制节点配置neutron用户及服务
$ . admin-openrc
$ 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
$ 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
配私有网络(还有一种网络是公用网络)
# yum install openstack-neutron openstack-neutron-ml2 \
