创建Nova用户并分配角色admin
openstack user create --domain default --password 000000 novaopenstack role add --project project --user nova admin创建Nova服务及服务端点
openstack service create --name nova computeopenstack endpoint create --region RegionOne nova public http://controller:8774/v2.1openstack endpoint create --region RegionOne nova internal http://controller:8774/v2.1创建admin用户访问的端点
openstack endpoint create --region RegionOne nova admin http://controller:8774/v2.1启动加开机自启

systemctl status openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service检测控制节点的Nova服务
查看端口占用情况
netstat -nutpl | grep 877查看计算服务列表
openstack compute service list配置计算节点nova服务(配置完再回来)
发现计算节点
