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 \
  openstack-neutron-linuxbridge ebtables
