To connect your EC2 instance server to a domain link, you can follow these general steps:

1. 1. Set up a web server on your EC2 instance: You can use Apache or Nginx to set up a web server on your EC2 instance. This will allow your instance to serve web pages over the internet.

3. 2. Configure your domain's DNS settings: You need to set up DNS records to point your domain to your EC2 instance's public IP address. You can do this by adding an A record to your domain's DNS settings.

5. 3. Upload your website files to the EC2 instance: Once you have a web server running on your EC2 instance, you need to upload your website files to the appropriate folder on the instance. This folder will typically be the "htdocs" or "public_html" folder.

7. Test your website: After you have uploaded your website files and set up your DNS records, you can test your website by navigating to your domain in a web browser. If everything is set up correctly, you should see your website displayed in the browser.

It's important to note that the specific steps for connecting your EC2 instance to a domain link may vary depending on your specific setup and the web server you are using. You may need to consult additional resources or documentation for your specific setup.
