在疯狂尝试解决时间同步问题时,我不知何故一定关闭了一些(但不是全部)日志记录。/var/log/messages 结束了最后一个事件,并且 journalctl -eu chronyd 没有显示任何新条目,尽管服务正在运行。重启后这种情况仍然存在。总结:
有点奇怪:chronyd 没有记录任何内容
其他服务正在记录
真的很奇怪,也有点吓人:天知道我昨晚做了什么, /var/log/messages 却没有任何变化。

答案1
问题已经自行解决。它发生在我的系统时间出现不稳定、大幅跳跃的时候。这些问题现在已得到解决,rsyslogd 正在运行并正确记录。系统时间的前后变化可能使 rsyslogd(和其他服务)感到不安。
