我使用外部 USB DVD 刻录机 (Matshita uj8e1) 在我们的远程服务器上刻录了 DVD。
烧录成功后系统弹出托盘。现在我遇到了将带有刻录 DVD 的托盘放回驱动器的问题。
我搜索了谷歌，我发现大多数东西只能在 Win7 或 XP 甚至更低版本中工作。我曾尝试使用 Wizmo、NirCMD 等工具，但没有成功。
有没有办法远程关闭 Windows Server 2012r2 中的驱动器托盘？
我刚刚在 Linux 上使用“DataStax All-in-One Installer”安装了 OpsCenter 5.0。
我试图通过在以下设置中添加身份验证/etc/opscenter/opscenterd.conf：
[authentication]
enabled = True
重新启动服务器后service opscenterd restart，身份验证仍然不存在。
我尝试使用文档说明启用 SSL，但也没有任何效果。服务器甚至不监听默认设置的 8443 端口。
分析日志文件后，/var/log/opscenter/opscenterd.log我没有发现任何相关的错误。
我想到了什么，是 OpsCenter 可能没有读取配置文件吗？为了检查这一点，我决定在配置文件中放入一些随机字符串，以在 OpsCenter 守护程序启动期间引发错误。重新启动后，日志文件仍然没有相关错误。
我的另一个想法是 OpsCenter 可能只是忽略了无效字符串？我已经删除了以前无效的字符串并在该部分中编辑了该port值。重新启动后 OpsCenter 仍在 8888 下侦听，而没有绑定到 8887。8887[webserver]
我最后一次尝试是重新启动整个服务器。它也没有帮助。
看起来 OpsCenter 根本不读取配置文件。什么会导致这种情况？我怎样才能解决这个问题？
谢谢你的时间，亚当
PS：这里是全部/var/log/opscenter/opscenterd.log内容。我还提供了一个PasteBin 链接以提高可读性。
