【问题描述】：

我无法通过任何 GUI 连接到 MongoDB。但是 MongoDB 是运行的，因为我可以使用 shell 顺利地管理 DM。

这是日志

我看到了一些类似的问题，并且有一些解决方案建议评论# bindIp: 127.0.0.1 并删除/var/lib/mongodb/mongod.lock。我的设置有问题吗？

您无法远程连接到正在运行的 MongoDB 实例可能有多种原因。我在这里列出几个原因：

服务器（您的 MongoDB 实例在其上运行）的防火墙可能会阻止来自外部 IP 的所有传入请求
如果您使用的是 Amazon EC2 实例，防火墙是不够的。您需要通过 Amazon 控制台打开端口和 IP
端口27017可能未在服务器上打开连接（使用各种端口检查来验证，如https://www.site24x7.com/port-test.html）
连接可能由于 TCP 超时而断开
尝试将bindIp 设置为0.0.0.0（参考：mongodb.conf bind_ip = 127.0.0.1 does not work but 0.0.0.0 works & MongoDB bind_ip won't work unless set to 0.0.0.0）
