#：加载环境变量

[root@cobbler ~]# source scripts/admin-stein.sh 

#：创建nova用户

[root@cobbler ~]# openstack user create --domain default --password-prompt nova

#：为admin项目添加一个用户nova，并添加到service角色

[root@cobbler ~]# openstack role add --project service --user nova admin

#：创建一个类型为compute的service

[root@cobbler ~]# openstack service create --name nova   --description "OpenStack Compute" compute

#：注册API

[root@cobbler ~]# openstack endpoint create --region RegionOne compute public http://www.magedu.net:8774/v2.1
