nginx記錄到access.log.1而不是access.log,logrotate失敗了嗎?
我有一個 nginx 實例,它設置為記錄對 /var/log/nginx/access.log 的訪問並將錯誤記錄到 /var/log/nginx/errors.log,但是一旦 logrotate 每週執行,文件就會移動到*.log.1 和新的 *.log 文件被創建,但 nginx 繼續記錄到 log.1 文件而不是新的 .log 文件(並且沒有任何內容被壓縮)。我第一次注意到這一點時,自日誌輪換以來已經 3 週了,並且日誌變得越來越大。執行
kill -HUP
cat /run/nginx.pid``使 nginx 再次開始登錄到正確的位置,但問題在下週再次出現。這令人沮喪的更重要原因是我將日誌設置為通過 rsyslog 上傳到 Loggly,當 nginx 停止記錄到文件時,我有 rsyslog 輪詢,然後事情停止上傳並且我沒有收到任何警報。
我懷疑它與重新啟動 nginx 或重新載入配置有關,因為它直到我進行了配置更改並以我認為正常的方式重新載入配置後才開始。我嘗試執行
kill -USR1
cat /run/nginx.pid,但文件繼續記錄到錯誤的位置,直到我執行`kill -HUP `cat /run/nginx.pid
,我已經知道這不能解決問題。知道發生了什麼嗎?我承認我不是 logrotate 或 nginx 管理方面的專家,但我的Google在這方面讓我失望了。
這是我的 nginx logrotate 腳本,如果您還想查看其他內容,請告訴我。除了定義輸出位置外,nginx.conf 在日誌記錄方面沒有什麼特別之處。

編輯:我想我發現了問題。以下是在調試模式下執行 logrotate 的輸出:

但是,只有大約 *.log.8.gz 的存檔,因此當 logrotate 嘗試與 .logrotate 互動時會失敗
/var/log/nginx/access.log.53.gz
。它到底為什麼要這麼做?我想我需要觸摸假文件來填寫?這似乎是錯誤的。
呸,挖了好久終於找到答案了。就我而言,問題不是 logrotate 失敗了。該錯誤消息很好,實際上並沒有停止 logrotate。問題是 nginx 在收到
-USR1
來自kill
. 長話短說,它沒有重新載入日誌文件的原因是該/var/log/nginx
文件夾與 nginx 工作程序(由 www-data 擁有,在 web 下執行)不屬於同一使用者。我不知道它是如何改變的(可能是因為該伺服器最近被重新製作),但是將文件夾更改為與 nginx 工作程序相同的使用者擁有(並修復 logrotate 文件以將新日誌製作為 web)解決了這個問題。
