Mongdb 啟動警告日誌

Mongdb 啟動警告記錄，我在這個論壇上看到很多關於這些警告的問題，但是我想知道這些警告記錄在哪裡。我可以在 mongod.log 中找到它們。

有人可以分享這些警告日誌的路徑嗎？

shell 中顯示的啟動警告mongo是 MongoDB 伺服器日誌的摘錄。在程序重新啟動之前，這些警告不會改變，所以如果你在預設的 MongoDB 日誌文件中找不到相應的條目，我希望日誌文件在程序啟動後已經輪換。

根據您的環境配置，舊的日誌文件通常會被重命名和壓縮，因此您可能需要搜尋不同的文件名或使用諸如zgrep搜尋壓縮文件之類的實用程序。

show log startupWarnings您可以通過或getLog管理命令重新顯示警告。
