我刚刚在 Linux 上使用“DataStax All-in-One Installer”安装了 OpsCenter 5.0。
我尝试通过以下设置来添加身份验证/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。
我尝试按照文档说明启用 SSL，但同样没有效果。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没有发现相关错误。
我想到的是，OpsCenter 可能没有读取配置文件？为了检查这一点，我决定将一些随机字符串放入配置文件中，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？我已删除了之前无效的字符串，并在部分中编辑了port值。重新启动后，OpsCenter 仍在 8888 下监听，而没有绑定到 8887。8887[webserver]
我最后一次尝试是重启整个服务器。但这也没什么用。
看起来 OpsCenter 根本就没有读取配置文件。是什么原因造成的？我该如何修复？
谢谢你的时间，亚当
PS：这是全部/var/log/opscenter/opscenterd.log内容。我还提供了一个PasteBin 链接以提高可读性。
