MongoError:连接 0 到 localhost:27017 超时 [英] MongoError: connection 0 to localhost:27017 timed out

问题描述

events.js:141
      throw er; // Unhandled 'error' event
MongoError: connection 0 to localhost:27017 timed out
at Function.MongoError.create (/home/ubuntu/scripts/node_modules/mongodb-core/lib/error.js:29:11)
    at Socket.<anonymous> (/home/ubuntu/scripts/node_modules/mongodb-core/lib/connection/connection.js:184:20)
    at Socket.g (events.js:260:16)
    at emitNone (events.js:67:13)
    at Socket.emit (events.js:166:7)
    at Socket._onTimeout (net.js:318:8)

    at Timer.unrefTimeout (timers.js:584:5)

好吧，连接过程中没有错误，但是当尝试保存一些模型/集合时，它会运行一段时间，然后抛出此错误.顺便说一句，我还有另一个节点进程连接到同一个 mongodb 服务器.任何帮助都受到高度赞赏.

Well there is no error during connection, but when try to save some models/collections it runs for a while and then it throws this error. BTW I also have another node process connected to the same mongodb server. Any help is highly appreciated.

推荐答案

const mongoose = require('mongoose');
const option = {
    socketTimeoutMS: 30000,
    keepAlive: true,
    reconnectTries: 30000
};

const mongoURI = process.env.MONGODB_URI;
mongoose.connect(mongoURI, option).then(function(){
    //connected successfully
}, function(err) {
    //err handle
});
