无法远程连接到mongodb，但可以在本地连接答案

【问题标题】：Can't connect to mongodb on remote but can on local无法远程连接到mongodb，但可以在本地连接
【发布时间】：2018-07-26 00:47:58
【问题描述】：

我正在尝试将我的node.js 服务器（在 ec2 实例上）连接到我的 mongodb 服务器（在 ec2 实例上但不一样）。一切正常，我可以在本地使用 mongo 连接到我的 mongodb，但我的 node.js 不能。如果我尝试输入此命令的事件：

mongo <ec2-instance>/<dbname> -u <username> -p <password> --authenticationDatabase <dbname>

我得到这个错误：

E QUERY [thread1] 错误：无法连接到服务器：27017，连接尝试失败： connect@src/mongo/shell/mongo.js:237:13 @(connect):1:6 异常：连接失败

【问题讨论】：

您可能需要打开 EC2 实例上的传入端口
参考：docs.aws.amazon.com/AWSEC2/latest/UserGuide/…
我不认为问题来自这里。一切都很好，但我的 mongodb 服务器崩溃了（我知道为什么）并且不会重新启动。我让它工作了一分钟，但现在不能再工作了

这是我尝试在我的实例上启动 mongod 时得到的结果..
