# admin 역할 추가

root@nw1 ~(keystone)# openstack role add --project service --user nova admin

 

# placement 사용자 생성
root@nw1 ~(keystone)# openstack user create --domain default --project service --password 'password입력' placement

# admin 역할 추가

root@nw1 ~(keystone)# openstack role add --project service --user placement admin

 

# nova service 생성
root@nw1 ~(keystone)# openstack service create --name nova --description "OpenStack Compute service" compute

# placement 서비스 생성

root@nw1 ~(keystone)# openstack service create --name placement --description "OpenStack Compute Placement service" placement

# Nova IP 정의

root@nw1 ~(keystone)# export controller=192.168.105.191

# nova endpoint 생성 - public
root@nw1 ~(keystone)# openstack endpoint create --region RegionOne compute public http://$controller:8774/v2.1/%\(tenant_id\)s

# nova endpoint 생성 - internal

root@nw1 ~(keystone)# openstack endpoint create --region RegionOne compute internal http://$controller:8774/v2.1/%\(tenant_id\)s

# nova endpoint 생성 - admin

root@nw1 ~(keystone)# openstack endpoint create --region RegionOne compute admin http://$controller:8774/v2.1/%\(tenant_id\)s

 

# placement endpoint 생성 - publice

root@nw1 ~(keystone)# openstack endpoint create --region RegionOne placement public http://$controller:8778

# placement endpoint 생성 - internal

root@nw1 ~(keystone)# openstack endpoint create --region RegionOne placement internal http://$controller:8778

# placement endpoint 생성 - admin

root@nw1 ~(keystone)# openstack endpoint create --region RegionOne placement admin http://$controller:8778
