我正在尝试控制本地 /var/log/syslog 文件。我当前的结构是将远程文件记录到 /var/log/juniper/syslog/%fromhost-ip%/syslog.log。以下是我的配置。
rsyslog.conf
/etc# cat rsyslog.conf
# /etc/rsyslog.conf Configuration file for rsyslog.

# Default logging rules can be found in /etc/rsyslog.d/50-default.conf

*.* ?JUNIPER可以有效地将所有人（包括 localhost）的所有内容记录到模板中$template JUNIPER,"/var/log/juniper/syslog/%fromhost-ip%/syslog.log”。
*.*;auth,authpriv.none -/var/log/syslog然后将我的日志文件加倍为常规 /var/log/syslog 文件。
我如何过滤这些结果，以便本地主机记录到其原始位置（/var/log/syslog）并且远程客户端仅记录到其各自的位置（/var/log/juniper/syslog/%fromhost-ip%/syslog.log）？
答案1
为了解决这个问题，我注释掉了$IncludeConfig /etc/rsyslog.d/*.conf2个基于IP的过滤条件并添加了它。
if $fromhost-ip == '127.0.0.1' then /var/log/syslog
if $fromhost-ip != '127.0.0.1' then ?JUNIPER
本质上，这会将来自本地主机的所有内容发送到 /var/log/syslog。然后，远程主机日志将被发送到其各自的动态目录。
