日志文件为空

我发现我的/ var / log / messages是空的！

我的/var/log/auth.log也是空的！

它也没有记录任何消息。

我的 /etc/rsyslog.conf 文件如下：

#  /etc/rsyslog.conf    Configuration file for rsyslog.
#
#                       For more information see

这里有什么问题？

我们也有这个问题。在2018-06更新Debian 9之后，rsyslogd不再写入日志文件了。

通过运行

service rsyslog status

我们发现了这个文件

/etc/rsyslog.d/named.conf

没有被正确读取，因此阻止了rsyslogd的运行。

我们不需要特定的Bind9（DNS）日志记录，因此我们将文件移动到了无法加载的扩展名：

mv /etc/rsyslogs/named.conf /etc/rsyslogs/named.conf.bak

重启rsyslogd后

service rsyslog restart

auth.log和其他文件现在正在按预期工作。
