我们提取关键字placement,查看nova.conf配置文件placement有没有写错我这里把password写错了
vim /etc/nova/nova.conf
[placement]
os_region_name = RegionOne
project_domain_name = demo
project_name = service
auth_type = password
user_domain_name = demo
auth_url = http://controller:5000/v3
username = placement
~~passowrd = 000000~~
password = 000000
写错了修正之后重启nova服务再次查看，
[root@controller ~]# systemctl restart openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
