发现配置文件错误

vi /etc/nova/nova.vonf

[keystone_authtoken]
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = project
username = nova
password = 000000

controller 少了一个n

如果

systemctl  start openstack-nova-api openstack-nova-conductor openstack-nova-scheduler openstack-nova-novncproxy

四个模块中有一个模块没有成功启动

systemctl  status openstack-nova-api openstack-nova-conductor openstack-nova-scheduler openstack-nova-novncproxy

看是哪个一个
可能是授权数据库的时候，打错了
