node.js - Bitnami Meanstack Mongoose Connection -

i created simple service in ubuntu 16.04 mongo db node , express return data angular 2 app.

i have file called server.js connects local mongodb instance database called game , collection called players. works fine installed on local machine. trying deploy bitnami's mean stack image on amazon ec2. (bleh mouth full). have set ports correctly according this guide, , can connect remotely. however, can't mongoose connect database. here code works on local machine.

mongoose.connect('mongodb://localhost:27017/game');  router.route('/player')    .get(function(req, res) {     console.log(mongoose.connection.readystate);     player.find({"player":user,"password":password},function(err, test) {         if (err)             res.send(err);          res.json(test);     }); }); 

and here adjusted code mean stack image

mongoose.connect('mongodb://root:"my-root-password@127.0.0.1:27017/game');  router.route('/player') .get(function(req, res) {  console.log(mongoose.connection.readystate);     player.find({"player":user,"password":password},function(err, test) {         if (err)             res.send(err);          res.json(test);     }); }); 

on local machine value of 1 on console.log , value of 0 on mean stack image. i'm not sure how connect bitnami's mongo instance mongoose. have checked game exist , has data want.

i found fix although don't yet understand it. came guide posted here . first had un comment out section of mongodb.conf says noauth = true comment out line says auth = true. restart mongo, , create new user permissions read , write the data base want use this

db.createuser({     user: "new username",     pwd: "new password",     roles:[             {                     "role" : "readwrite",                     "db": "game"             }     ]}) 

after creating user undo did noauth = true , auth = true, , restart mongodb. able connect mongoose this

mongoose.connect('mongodb://new username:new password@127.0.0.1:27017/game');
