nodejs 无法使用猫鼬连接到 mongodb

Question

so all my applications were working just fine using mongoose, all of a sudden they all stopped. i cant connect to my database. however my deployed apps using mongoose databases work fine, but i cant access to any database using my local computer. here is a test server ive written. can someone help me whats happening.

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser')

const app = express();

app.use(express.json())

const db = require('./keys').mongoURI;

mongoose.connect(db, { useNewUrlParser: true, useUnifiedTopology: true })
    .then(() => console.log('connected'))
    .catch(err => console.log(err))

const port = process.env.PORT || 5000;

app.listen(port, () => console.log('server running'))



module.exports = {
    mongoURI: 'mongodb+srv://ertemishakk:<password>@cluster0-xi4zx.mongodb.net/test?retryWrites=true&w=majority'
}

Terminal: server running MongoTimeoutError: Server selection timed out after 30000 ms at Timeout._onTimeout (/Users/ishakertem/Desktop/test/node_modules/mongodb/lib/core/sdam/server_selection.js:308:9) at listOnTimeout (internal/timers.js:536:17) at processTimers (internal/timers.js:480:7) { name: 'MongoTimeoutError', }

Answer 1

You should check your

bindIp : [public_ip]

option in

mongod.conf

file. It should be pointed out to public IP of that system on which MongoDB is running. You can use 0.0.0.0 for debuging only, because it is exposed One.

You Can Follow This Code I hope solved your problem

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser')

const app = express();

app.use(express.json())


//Remove <password> and provide DB password
/**
 * Example: mongodb + srv: //ertemishakk:123@cluster0-xi4zx.mongodb.net/test?retryWrites=true&w=majorit
 */
mongoose.connect('mongodb+srv://ertemishakk:<password>@cluster0-xi4zx.mongodb.net/test?retryWrites=true&w=majorit', {
        useNewUrlParser: true,
        useUnifiedTopology: true
    })
    .then(() => console.log('connected'))
    .catch(err => console.log(err))

const port = process.env.PORT || 5000;

app.listen(port, () => console.log('server running'))
