xkc*_*150 22 linux monitoring log-files tail logrotate
我们使用 tail 来连续监视多个日志,但是当日志旋转时,该文件的尾部将停止。
据我了解,问题是当日志轮换时,会创建一个新文件,而正在运行的尾部进程对该新文件句柄一无所知。

啊,这有一面旗帜。
tail -f /var/log/file我们应该使用而不是使用tail -F /var/log/file
tail -F翻译tail --follow=name --retry成在;
--follow=name: 跟随文件名而不是文件描述符--retry: 如果文件无法访问,请稍后重试而不是死亡djh*_*ell 27
# tail --follow=mylog.log

从人尾巴:
With --follow (-f), tail defaults to following the file descriptor,
which means that even if a tail’ed file is renamed, tail will continue
to track its end. This default behavior is not desirable when you
really want to track the actual name of the file, not the file descrip?
tor (e.g., log rotation). Use --follow=name in that case. That causes
tail to track the named file by reopening it periodically to see if it
has been removed and recreated by some other program.

所以在这种情况下使用该-F选项是正确的。
-F same as --follow=name --retry

确切的答案取决于您的操作系统 - 但在许多情况下,tail -F会做正确的事情。
