![日志文件是空的](https://linux22.com/image/1563655/%E6%97%A5%E5%BF%97%E6%96%87%E4%BB%B6%E6%98%AF%E7%A9%BA%E7%9A%84.png)
我发现我的 /var/log/messages 是空的!
而且我的 /var/log/auth.log 也是空的!
它还没有记录任何消息。
我的/etc/rsyslog.conf
文件如下:
# /etc/rsyslog.conf Configuration file for rsyslog.
#
# For more information see
# /usr/share/doc/rsyslog-doc/html/rsyslog_conf.html
#
# Default logging rules can be found in /etc/rsyslog.d/50-default.conf

这里有什么问题?

我/etc/rsyslog.d/50-default.conf
的如下:

#
# For more information see rsyslog.conf(5) and /etc/rsyslog.conf
#
# First some standard log files. Log by facility.
#

我们也遇到了这个问题。在 2018-06 更新到 Debian 9 后,rsyslogd 不再写入日志文件。
通过运行
service rsyslog status
我们发现该文件
/etc/rsyslog.d/named.conf
没有被正确读取,因此阻止了 rsyslogd 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不会加载的扩展名:
mv /etc/rsyslogs/named.conf /etc/rsyslogs/named.conf.bak
重新启动 rsyslogd 后
service rsyslog restart
auth.log 和其他文件现在按预期工作。
