##5.1 Nova控制节点

 

##5.1 Nova控制节点
# controller 安装
#5.1.Nova-controller.sh

#创建Nova数据库、用户、认证，前面已设置
source ./admin-openstack.sh || { echo "加载前面设置的admin-openstack.sh环境变量脚本";exit; }

# keystone上服务注册 ,创建nova用户、服务、API
# nova用户前面已建
openstack service create --name nova --description "OpenStack Compute" compute
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
#创建placement用户、服务、API
openstack user create --domain default --password=placement placement
openstack role add --project service --user placement admin
openstack service create --name placement --description "Placement API" placement
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
#openstack endpoint delete id?
