rsyslog 伺服器將遠端日誌保存在 /var/syslog 中

rsyslog 伺服器將遠端日誌保存在 /var/syslog 中

我已將 ubuntu 伺服器設定為 syslog 伺服器，以接受來自路由器的所有日誌並將它們保存在 /var/log/ 資料夾中的單獨 mikrotik.log 檔案中。

一切正常，但我注意到所有訊息也被複製到 /var/syslog 日誌檔案中。

有沒有辦法可以停止在我的 /var/syslog 日誌中保留這些路由器訊息？

以下是我的系統日誌設定檔：

/etc/rsyslog.d/10-mikrotik.conf

$template RouterLog, "/var/log/mikrotik.log"
:fromhost-ip, isequal,    "192.168.2.1" -?RouterLog
& stop

/etc/rsyslog.d/50-default.conf

答案1

就在發布這個問題之前我改變了：

/etc/rsyslog.d/mikrotik.conf

到：

/etc/rsyslog.d/10-mikrotik.conf

它確實解決了我的問題，但我現在才發現它。

答案2

嘗試在不重複的規則之後立即新增此行。

& ~

例如編輯/etc/rsyslog.d/10-mikrotik.conf看起來像

$template RouterLog, "/var/log/mikrotik.log"
:fromhost-ip, isequal,    "192.168.2.1" -?RouterLog
# & stop
& ~

這應該會阻止日誌訊息的副本繼續發送到/var/log/syslog

然後，當然運行service rsyslog restart
