?️ Node.js Hello World on EC2 — Keep It Running Forever with PM2


Great for testing simple deployments on any cloud (AWS EC2, DigitalOcean, etc.).

Full Setup Guide (Step-by-Step)

? Step 1: Install Node.js and NPM Using NVM

| bash

# Activate NVM
. ~/.nvm/nvm.sh

# Install latest Node.js
nvm install node

# Verify installation
node -v
npm -v
? Step 2: Install Git and Clone the Repository


# Update packages
sudo apt-get update -y

# Install Git
sudo apt-get install git -y

# Verify Git version
git --version

# Clone the Node.js sample repo
git clone

# Move into the project directory
cd nodejs-on-ec2

# Install dependencies
npm install
? Step 3: Start the Application (For Testing)


npm start

Your app will now serve "A Monk in Cloud" — but it will stop when the terminal is closed or the server reboots. To fix that, let’s keep it running with PM2 ?

? Step 4: Install and Use PM2 to Keep App Alive

? Install PM2 globally:


npm install -g pm2
Start the App with PM2:


pm2 start index.js --name BackendAPI

? Replace index.js with the name of your main JS file if different.

Step 5: Keep App Running After Reboot


pm2 startup

Copy and run the command it outputs (something like this):


sudo env PATH=$PATH:/root/.nvm/versions/node/vXX/bin /root/.nvm/versions/node/vXX/lib/node_modules/pm2/bin/pm2 startup systemd -u root --hp /root

Then save the PM2 process list:


pm2 save
? Step 6: PM2 Useful Commands


pm2 list # Show running apps
pm2 logs # Show app logs
pm2 restart monk-app # Restart the app
pm2 stop monk-app # Stop the app
pm2 delete monk-app # Remove it from PM2
Final Result

• Node.js is installed with NVM
• App is deployed and running
• PM2 keeps it alive forever
• App auto-starts after reboot

Optional


You can also:

• Use NGINX as a reverse proxy for clean domain access
• Add HTTPS with Let’s Encrypt
• Connect a CI/CD pipeline
