I am trying to connect to my local mongodb with my node express app hosted on litghtsail MEAN bitnami.
The connection string im using with mongoosse client look like this: mongodb://app:sang#127.0.0.1:27017/prisedesang
Im able to connect whit that user remotely with a SSH tunnel. Im able to connect with that same user localy using mongo cli.
However when I use the app I get ERR_CONNECTION_REFUSED when I try to connect to the db hosted on the same server... Any suggestion?
Can you try using MongooseJS? You can connect your application with MongoDB using MongooseJS, an object modeling driver for Node.js. It is already installed in the MEAN stack so you only have to add the following lines to your app.js file:
var Mongoose = require('mongoose');
var db = Mongoose.createConnection('mongodb://USER:PASSWORD#localhost/DATABASE');

I have a MongoDB Database set up on my host server and a docker container running on that host with a NodeJS application. In that application, I try to connect to the Database on the host but the request always times out.
I set the network to "host" and used the adress "host.docker.internal". I also tried installing mongodb-shell and it actually works! So basically I can connect to the database with the shell in the container but not with the MongoDB NodeJS API.
Code of the NodeJS application:
const mongodb = require('mongodb');
mongodb.MongoClient.connect("mongodb://host.docker.internal:27017/");
using mongo mongodb://host.docker.internal:27017/ in the shell works and I connect correctly.
I finally found out the issue.
I had to bind it to the correct IPs / in my config I used the argument --bind_ip_all.
Thanks a lot for the help!
I recently started working on a project with Express and since I'm using Node.js as backend I chose MongoDB as my database. It's my first time working with Mongo but I can't authenticate with Express, it works fine from terminal. I followed the guide from MogoDB blog here. I tried using their Atlas service where I had no problem authenticating. I'm using MongoDB driver. Here's how my connection URI looks like:
const uri = `mongodb://${username}:${password}#127.0.0.1/cloud?retryWrites=true&w=majority`;
I tried changing mongodb:// to mongodb+srv:// but that resulted in invalid connection string error.
You need to specify the authentication database, usually admin:
const uri = `mongodb://${username}:${password}#127.0.0.1/cloud?authSource=admin&retryWrites=true&w=majority`;
If you don't specify it then in your case MonogDB defaults the authentication database to cloud - which is most likely wrong.
When you are accessing mongodb on the web you can click on connect and on connect your application. You will show the uri to copy paste starting with
mongodb+srv://USERNAME:PASSWORD#CLUSTER/DATABASE
You forgot to specify the CLUSTER. Currently is your local Database
I am trying to connect to my AWS Bitnami MEAN instance. The code has been uploaded on the server. But on connecting to it, I am getting the following error :
I have been following the steps given at : https://scotch.io/tutorials/deploying-a-mean-app-to-amazon-ec2-part-1 to connect to the instance.
In the second aprt of it, where they are making changes for mongoDB, I did all those, but since then, I am getting this error.
Your connection is being refused, it seems like an authentication error. You must provide the password in your application, i.e. if you are using Mongoose in order to connect:
var Mongoose = require('mongoose');
var db = Mongoose.createConnection('mongodb://*USER:PASSWORD*#localhost/*DATABASE*');
You must use your correct mongodb socket and your correct password and database name.

I've recently setup an ec-2 instance to deploy a meteor application on AWS. My app works correctly with mongoDB database.
Now I want to connect my meteor project's database to the EC2 database and then I've tried some command lines :
start my meteor project with a new mongo url with the following command line : "MONGO_URL="mongodb://username:password#xx.xx.xxx.xxx:27017/Tasks" meteor" but it returns the following screen
connect to mongo with the other following command line :
"meteor mongo --url xx.xx.xxx.xxx:27017" but it returns a timeout. I thought it was due to the lack of username and password however when I add this option meteor does not assume the command.
connect to mongo in my js collection file with
"export const Tasks = mongoose.connect("mongodb://username:password#xx.xx.xxx.xxx:27017/Tasks").connection;" but it returns "Error: connect ECONNREFUSED" (second screen)
Is there any tips to manage to establish database connection from local meteor ?
Thank you for answer,
Martin
If the database and the Meteor processes are in the same machine, you can call it from "localhost".
MONGO_URL="mongodb://user:password#localhost/Tasks"
If you really want to use the IP + Port approach, you have to ensure that it's accessible from the EC2 Security Groups you're using.
The same applies for connecting manually in Mongoose but you should't be using Mongoose with Meteor, it has it's own way of handling collections. If you need something more powerful, or a way to extend it yourself checkout the Meteor Simple Schema project.
I installed mongo on my elastic beanstalk node.js app and started the mongo daemon process. I'm not quite sure how to connect to the database though. On my local node app, I'm able to connect with these credentials:
module.exports = {
'url' : 'mongodb://127.0.0.1:27017/test'
}
I'm assuming that it doesn't connect because I need a user, password, and to create a database to connect to, but I'm not sure how to go about doing that on the remote database. I'm also finding resources on setting mongo up on t1.micro to be very scarce, so there's not much help there.
I didn't realize that I had to start up the mongo processes myself. Run mongod.
