   • Add a rule to allow HTTP (port 80) and Grafana (default port 3000).

   • Allow SSH (port 22) from your IP for remote access.

9. Review and Launch: Review your settings and launch the instance.

Step 2: Connect to Your EC2 Instance

1. Use SSH to connect to your instance:

    ssh -i /path/to/your-key.pem ec2-user@your-ec2-public-dns
   

Step 3: Install Grafana

For Amazon Linux 2 or Ubuntu, follow these commands:

1. Update the package repository:

    sudo yum update -y      # For Amazon Linux
