I recently set up a website on an AWS EC2 instance, but I’m having trouble getting my domain name to point to it. I purchased my domain through a registrar, and I thought it would be simple to link it to my EC2 instance, but I’m stuck. I’ve logged into the EC2 management console and launched my instance, but I’m unsure what the next steps are to associate my domain name with my public IP address.
I understand that I need to configure the DNS settings, but there seems to be a lot of technical jargon that I don’t fully grasp. I’ve encountered terms like A records, Name Servers, and Elastic IPs, and it’s making my head spin. Also, should I be using Amazon Route 53 for DNS management, or can I stick with my current registrar? If I do use Route 53, how do I set that up? Any advice on the steps I need to take to make my domain name accessible to visitors who want to view my site running on EC2 would be incredibly helpful. I really want to get this resolved as soon as possible!
Using Your Domain Name with AWS EC2
Okay, so you have a cool domain name and you want to use it with your AWS EC2 instance. No worries, it’s easier than it sounds! Let’s break it down step by step.
Step 1: Get Your EC2 Public IP
After you launch your EC2 instance, you need to find its public IP address. Go to your AWS Management Console, navigate to your EC2 dashboard, and look for instances. Click on your instance and grab that IP! It should look like this: 123.456.78.90.
Step 2: Access Your Domain Registrar
Next, log in to the website where you bought your domain name (like GoDaddy, Namecheap, etc.). You’ll need to change some settings there.
Step 3: Update DNS Records
Look for a section called DNS Management or DNS Settings. Here, you can update the DNS records. You’ll want to create a new A record.

Once you save those changes, it might take a little while (like a few minutes to a couple of hours) for the changes to go through. Patience, young grasshopper!
Step 5: Test It Out!
After some time, open your browser and type in your domain name. It should take you to your EC2 instance! If you see something like a welcome page or your app, you did it right!
Troubleshooting
If it’s not working, double-check that you set the A record correctly, and make sure your EC2 instance is running and accessible. You can also check your instance’s security group settings to ensure it allows HTTP/HTTPS traffic.
And there you go! You’ve linked your domain name with your EC2 instance like a pro! 🎉
To use your domain name with an AWS EC2 instance, you’ll first need to ensure that your domain’s DNS settings are properly configured. Log in to your domain registrar’s management console and locate the DNS settings. Here, you should create an A record that points your domain name to the public IP address of your EC2 instance. This will involve entering your domain name (e.g., example.com) and the public IP address of your EC2 instance that you can find in the AWS EC2 dashboard. If you want to use a subdomain, say http://www.example.com, you would set up a similar A record for that subdomain.
Next, ensure that your EC2 instance is configured to respond to incoming traffic on the required ports (typically 80 for HTTP and 443 for HTTPS). This is managed through the Security Groups associated with your EC2 instance. Update the inbound rules in the Security Group to allow traffic from 0.0.0.0/0 for HTTP and HTTPS. Once you’ve completed these configurations, you may also want to consider setting up an Elastic IP for your EC2 instance to maintain a consistent IP address, even if the instance is stopped and started again. Lastly, verify that your instance’s web server (like Apache or Nginx) is configured to serve content correctly when accessed through your domain name.
