MEAN is a FOSS (Free and Open Source Software) JavaScript stack for developing frontend and backend software for websites. Everything in the MEAN stack supports JavaScript software, which means only one language is required for developing on the server (backend), and website (frontend). MEAN stands for MongoDB, ExpressJS, AngularJS, and NodeJS, which are individual technologies designed to work together.

1. Deploy Ubuntu Server

Change to your sudo user for the remaining steps.

2. Install MongoDB

Update sources and install MongoDB.

$ sudo apt update && sudo apt install -y mongodb

Start and enable MongoDB on boot.

$ sudo systemctl start mongodb
$ sudo systemctl enable mongodb

3. Install NodeJS and Dependencies

Use the official nodesource script to get the latest version of NodeJS.

$ curl -sL | sudo -E bash -

Install NodeJS, build dependencies, and git.

$ sudo apt install -y nodejs gcc g++ make git

Use npm to install yarn and gulp.

$ sudo npm install -g yarn
$ sudo npm install -g gulp

Clone the official MeanJS repository.

$ git clone

Change to the MeanJS directory.

$ cd mean

Install dependencies with yarn.

$ yarn install

4. Test

Open the server.js file.

$ nano server.js

Replace the contents with the following code.

const express = require('express');
const MongoClient = require('mongodb').MongoClient;
const app = express();

app.use('/', (req, res) => {
    MongoClient.connect("mongodb://localhost:27017/test", function(err, db){
        db.collection('Example', function(err, collection){
            collection.insert({ pageHits: 'pageHits' });
            db.collection('Example').count(function(err, count){
                if(err) throw err;
                res.status(200).send('Page Hits: ' + Math.floor(count/2));

console.log('Server running at http://localhost:3000/');

module.exports = app;

Start the server.

$ gulp

To verify the server is running and can access the database correctly, navigate to your page URL. Substitute with your server's IP address.

You should see "Page Hits: " with an increasing number each time you refresh the page. This verifies the MEAN stack is functioning properly.


You have successfully installed a MEAN stack on your Ubuntu 20.04 LTS VPS. For more information about MEAN, and further guides, see the official documentation:
