Linux

系統日誌為空(/var/log/messages;/var/log/secure;等)

  • December 8, 2020

我發現 rsyslog 停止寫入日誌(消息;安全;cron 等)

系統資訊:NAME=“Red Hat Enterprise Linux Server” VERSION=“7.4 (Maipo)” ID=“rhel” ID_LIKE=“fedora” VARIANT=“Server” VARIANT_ID=“server” VERSION_ID=“7.4”

已經重新啟動 rsyslog 沒有結果。rsyslogd 處理的其他日誌正在寫入沒有問題。

還重新啟動了 systemd-journald。

rsyslog.conf(省略註釋行):

$ModLoad imuxsock
$ModLoad imjournal
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf

local3.*                                                /var/log/sshd-second.log

Journald.conf(省略註釋行):

[Journal]

已刪除 /run/log/journal/* 並重新啟動 journald 已刪除 imjournal.state 並重新啟動 rsyslog

命令 rsyslogd -N 1 的輸出:

rsyslogd: version 8.24.0, config validation run (level 1), master config /etc/rsyslog.conf

rsyslogd:配置驗證執行結束。再見。

命令 rsyslogd -N 6 的輸出:

rsyslogd: version 8.24.0, config validation run (level 6), master config /etc/rsyslog.conf

rsyslogd:配置驗證執行結束。再見。

已經嘗試了https://unix.stackexchange.com/questions/124942/rsyslog-not-logging中描述的所有解決方案,但沒有結果

lsof -p 的輸出

有沒有人有任何線索?

嗯……差不多2年過去了,終於找到了解決這個問題的辦法。如果有人有同樣的問題,請嘗試以下步驟。

系統日誌版本rsyslogd 8.24.0-38.el7

該問題與imjournal模組有關。我已經刪除了 rsyslog.conf 中與 imjournal 相關的所有條目****,並將OmitLocalLogging切換為關閉

之後,我使用systemctl restart rsyslog重新啟動了 rsyslog 服務,並且日誌條目開始填充到我在 rsyslog.conf 中配置的日誌文件中。

rsyslog.conf 文件現在如下所示:

$ModLoad imuxsock
#$ModLoad imjournal
$ModLoad immark 
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging off
#$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none                /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
