connect ECONNREFUSED 127.0.0.1:27017'

Question

I have that code:

var express = require('express'),
    stylus = require('stylus'),
    logger = require('morgan'),
    bodyParser = require('body-parser'),
    mongoose = require('mongoose');

var env = process.env.NODE_ENV = process.env.NODE_ENV || 'development';

var app = express();

function compile(str, path){
    return stylus(str).set('filename', path);
}

app.set('views', __dirname + '/server/views');
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(stylus.middleware(
        {
            src: __dirname + '/public',
            compile: compile
        }
    ));
app.use(express.static(__dirname + '/public'));

mongoose.connect('mongodb://localhost/multivision');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error..'));
db.once('open', function callback(){
    console.log('multivision db opened');
});

app.get('/partials/:partialPath', function(req, res){
    res.render('partials/' + req.params.partialPath);
});

app.get('*', function(req, res) {
  res.render('index');
});

var port = 3131;
app.listen(port);
console.log('Listening on port ' + port + '...');

but when I'm trying nodemon server.js it throws an error:

connection error.. { [MongoError: connect ECONNREFUSED 127.0.0.1:27017] name: 'MongoError' message: 'connect ECONNREFUSED 127.0.0.1:27017' }

how can I improve that? I've already installed mongoose using npm install mongoose --save in my directory

Yeah there are dozens question like this but none of these helped me.. I'm new at nodejs and probably missing something

Does mongodb run on the same host? The 27017 port is the default mongodb port and it seems that no mongodb is available there. — TeTeT
I'm going through this tutorial pluralsight.com/courses/building-angularjs-nodejs-apps-mean and he haven't done anything to run mongodb. only installed it and then nodemon server.js — gsiradze

run services.msc and activate the Mongodb service.

Now Mongodb will connect

the status of the Mongodb indicated as Running

connect ECONNREFUSED 127.0.0.1:27017'
