AWS-Session

1. Launch EC2 Instance

  • Go to AWS Console → EC2 Dashboard → Launch Instance.
  • Choose Amazon Linux 2 (or Ubuntu).
  • Select t2.micro (free-tier eligible).
  • Configure Security Group to allow:
    • SSH (Port 22) for access.
    • HTTP (Port 80) for web traffic.
  • Launch Instance and Download the Key Pair.

2. Connect to EC2

  • Use the downloaded key to SSH into your EC2 instance: 
    ssh -i /path/to/key.pem ec2-user@<EC2_PUBLIC_IP>

3. Set Up Environment

  • Update packages: 
    sudo yum update -y   # Amazon Linux
  • Install Node.js: 
    curl -sL https://rpm.nodesource.com/setup_16.x | sudo bash -
sudo yum install -y nodejs

4. Deploy Node.js App

  • Clone your app (if in GitHub): 
    git clone https://github.com/your-username/your-app.git
cd your-app
  • Install dependencies: 
    npm install

5. Run the App

  • Start your Node.js app: 
    node app.js
  • Ensure your app listens on Port 80 (use iptables if needed to redirect traffic): 
    sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000

6. Access Your App

  • Visit your EC2 instance’s public IP in the browser: 
    http://<EC2_PUBLIC_IP>

This should get your Node.js app running on an EC2 instance quickly!
