我可以从redhat shell连接

  

mongo --port 34672

但是当我尝试从外部IP连接时，它失败了。

检查完所有错误日志并在网上搜索后，我无法找到此错误的原因。

Answer 1

这些日志条目不表示错误。它只是报告连接。至于连接的原因，可能有几个：

1. 如果您有使用MongoDB的应用程序，则这些连接可能来自该应用程序。
2. 如果您安装了Stackdriver Monitoring等监控，这些可能是监控的连接，以从MongoDB获取统计信息。
3. 如果您使用的是MongoDB服务器群集，则可能是它们之间的连接或健康检查。

我认为（2）或（3）特别有可能，因为它们来自内部IP地址的距离恰好相隔30秒。

我认为您在外部连接的问题与这些消息无关。如果那是你真正关心的问题，我建议你提出一个新问题。
