手动配置，只要有错。大概率就是某个地方疏忽了
看日志情况，应该是 nova.conf 中 passowrd 错了

vim /etc/nova/nova.conf

果然发现遗漏了

改正后，按照 Install and configure controller node for Ubuntu 重启服务

# service nova-api restart
# service nova-scheduler restart
# service nova-conductor restart
# service nova-novncproxy restart

如果存在 compute 节点的话，按照Install and configure a compute node for Ubuntu 重新同步发现

也在 Controller 节点执行

$ . admin-openrc

$ openstack compute service list --service nova-compute

# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
