Deploying a MERN Stack App on AWS EC2

Deploying a MERN Stack App on AWS EC2

Introduction

AWS EC2 is a scalable cloud server where we can host a MERN stack app. This guide walks through deployment.

Step 1: Launch an EC2 Instance

1. Log in to AWS Console.
2. Choose Ubuntu Server 20.04.
3. Configure security group to allow HTTP, HTTPS, and SSH access.

Step 2: Connect to EC2

Use SSH:

ssh -i your-key.pem ubuntu@your-ec2-instance-ip

Step 3: Install Node.js & MongoDB

curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt install -y nodejs mongodb

Step 4: Deploy MERN App

Clone your repo, install dependencies, and start the app:

git clone https://github.com/your-repo.git
cd your-repo
npm install
node server.js

Step 5: Setup PM2 for Process Management

npm install -g pm2
pm2 start server.js --name mymernapp
pm2 save
pm2 startup

Step 6: Configure Nginx as a Reverse Proxy

sudo apt install nginx
sudo nano /etc/nginx/sites-available/default

Add this configuration:

server {
    listen 80;
    server_name your-domain.com;

    location / {
        proxy_pass http://localhost:5000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Restart Nginx:

sudo systemctl restart nginx

Conclusion

Your MERN app is now running on AWS EC2 with Nginx handling traffic.
