Mongdb 启动警告日志

  • 772

Mongdb 启动警告记录，我在这个论坛上看到很多关于这些警告的问题，但是我想知道这些警告记录在哪里。我可以在 mongod.log 中找到它们。

有人可以分享这些警告日志的路径吗？

    shell 中显示的启动警告mongo是 MongoDB 服务器日志的摘录。在进程重新启动之前，这些警告不会改变，所以如果你在默认的 MongoDB 日志文件中找不到相应的条目，我希望日志文件在进程启动后已经轮换。

    根据您的环境配置，旧的日志文件通常会被重命名和压缩，因此您可能需要搜索不同的文件名或使用诸如zgrep搜索压缩文件之类的实用程序。

    show log startupWarnings您可以通过或getLog管理命令重新显示警告。
