我可以从红帽外壳连接为

蒙戈 --端口 34672

但是当我尝试从外部IP连接时，它失败了。

在检查所有错误日志并在网络上搜索后，我无法找到此错误的原因。

Answer 1

这些日志条目不指示错误。它只是报告连接。至于连接的原因，可能有几个：

1. 如果你有一个使用MongoDB的应用程序，这些连接可能来自该应用程序。
2. 如果您安装了诸如堆栈驱动程序监控之类的监控，则这些可能是来自监控的连接，以从MongoDB获取统计信息。
3. 如果您使用的是MongoDB服务器集群，这可能是它们之间的连接或运行状况检查。

我认为 (2( 或 (3( 特别有可能，因为它们来自内部 IP 地址，间隔正好 30 秒。

我相信您在外部连接的问题与这些消息无关。如果这是你真正关心的，我建议你提出一个新问题。
