解决 openstack-nova-scheduler/conductor 开启失败

openstack-nova-scheduler和openstack-nova-conductor是OpenStack Nova的两个核心组件，它们分别负责调度和管理虚拟机实例。如果它们无法启动，通常会有以下几个方面的问题：

1. 数据库连接问题：检查数据库的配置是否正确，并确保nova-scheduler.conf和nova-conductor.conf中的数据库连接设置正确。

2. 证书问题：如果OpenStack使用证书进行身份验证，确保证书文件正确并且nova-scheduler.conf和nova-conductor.conf中的证书配置正确。

3. 服务的依赖问题：检查nova-scheduler和nova-conductor的依赖关系是否正确，并确保所有必需的服务都已启动。

4. 日志文件检查：检查/var/log/nova目录下的日志文件，如果有错误信息，则可以根据错误信息进行排除。

如果以上方法无法解决问题，可以尝试重新安装nova-scheduler和nova-conductor组件，或者在OpenStack社区寻求帮助。

这段提示信息表示启动 openstack-nova-api、openstack-nova-scheduler、openstack-nova-conductor、openstack-nova-novncproxy 服务时，openstack-nova-scheduler 和 openstack-nova-conductor 服务启动失败了。建议你执行以下命令检查相关服务的状态并查看详细错误信息：

systemctl status openstack-nova-scheduler.service
journalctl -xe
systemctl status openstack-nova-conductor.service
journalctl -xe

通过查看详细错误信息，你可以更清楚地了解问题所在，并进行相应的修复。
