Cannot Connect to MongoDB with Bitnami MEAN STACK using Mongoose

Question

I purchased the MEAN tech stack from AWS (Bitnami to be specific) and have been eagerly trying to learn how to deploy my first node app. However, I have been hitting so many walls with actually getting my mongo connection to work. I have read documentation and tried various recipes to fix the issue below

The root admin password has been reset. Here is the proof that I am using the correct pair of username and password

> bitnami@ip-172-31-43-127:~/edupal$ sudo mongo admin --username root --password
pwdremoved
MongoDB shell version: 3.0.3
connecting to: /opt/bitnami/mongodb/tmp/mongodb-27017.sock:27017/admin
Server has startup warnings:
2015-06-09T20:11:33.967+0000 I CONTROL  [initandlisten]
2015-06-09T20:11:33.967+0000 I CONTROL  [initandlisten] ** NOTE: This is a 32 bi

> db.myCollection.find()
{ "_id" : ObjectId("5578c11040a096b7fef84aad"), "name" : "Bill", "score" : "9" }

So far, I believe I am in good standing in terms of credentials. Here is how I am connecting to my database

// Connect to MongoDB
mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/
mongodb-27017.sock/admin');
mongoose.connection.once('open', function() {

  // Load the models.
  app.models = require('./models/index');

  // Load the routes.
  var routes = require('./routes');
  _.each(routes, function(controller, route) {
    app.use(route, controller(app, route));
  });

  console.log('Listening on port 3000...');
  app.listen(8080);
});

I followed the tutorial here

and I keep getting this error

I am not sure what I am doing wrong and have tried many variations of connecting to MongoDB....I've been stuck for two days now.

Bitnami developer here.

You posted that you can connect to the admin database using the root user

bitnami@ip-172-31-43-127:~/edupal$ sudo mongo admin --username root
--password pwdremoved MongoDB shell version: 3.0.3 connecting to: /opt/bitnami/mongodb/tmp/mongodb-27017.sock:27017/admin

but later you tried to connect to the "indexes" database

mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/mongodb-27017.sock/indexes');

Is that database created? You can check the created databases with this command:

show dbs

If you want to use the admin database you will need to use this line:

mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/mongodb-27017.sock/admin');

You could check this guide to learn how to create a database and grant privileges to a new user if you don't want to use the root user and the admin password.

https://wiki.bitnami.com/Components/mongoDB#How_to_create_a_database_for_a_custom_application.3f

I installed Meanstack 3.0.3-0 and I followed the tutorial in our wiki about how to create a sample TODO list and everything works fine. You can check it the following link.

I hope this helps.
