sudo apt-get install -y nodejs

Confirm NodeJS is install by checking the version of NodeJs installed with this command:

node -v

Next install git with the following command:

sudo apt-get install git

Git is a free and open-source distributed version control system. You will clone a git repository containing a simple node app from Github, modify it and deploy. Git might already be installed on the instance.

Clone the Node app files by running:

git clone https://github.com/neveropen/Simple-Node-JS-App.git

Navigate to the directory with:

cd node-app

Then install Node dependencies which will create the node-modules folder by running:

npm install

Your application can now be deployed live when you run:

node index.js

The app is running as soon as you open the terminal and it will terminate as you will close the terminal. you will install PM2 (Production manager 2) to keep live our app after closing our terminal or disconnect from the remote server. Run the following command:

sudo npm install pm2 -g

PM2 will be installed on the server globally. Run your app using PM2:
