Setting up a DNS Server on AWS can seem daunting at first, but with the right steps, it becomes a straightforward process. In this tutorial, we will walk through the necessary steps to get your DNS server up and running.

Step 1: Launch an EC2 Instance

The first step is to launch an EC2 instance that will act as your DNS server. To do this, follow these steps:

  • Step 1: Log in to your AWS Management Console.
  • Step 2: Navigate to the EC2 service.
  • Step 3: Click on “Launch Instance” to start the EC2 instance creation process.
  • Step 4: Choose an Amazon Machine Image (AMI) that suits your needs. For example, you can select an Amazon Linux AMI.
  • Step 5: Choose an instance type based on your requirements. For a DNS server, a t3.micro instance should suffice.
  • Step 6: Configure the instance details as per your preferences and requirements.


Make sure to configure the security group settings appropriately to allow inbound traffic for DNS services like port 53 (UDP/TCP).

Step 2: Update and Install Required Packages

Once you have successfully launched your EC2 instance, follow these steps to update and install the required packages:

  • Step 1: Connect to your EC2 instance using SSH or any other preferred method.
  • Step 2: Update the package manager by running the command: sudo yum update -y.
  • Step 3: Install the DNS server package (Bind) by running the command: sudo yum install bind -y.

Step 3: Configure the DNS Server

With the necessary packages installed, it’s time to configure the DNS server:

  • Step 1: Locate and open the Bind configuration file using a text editor. The file is usually located at /etc/named.conf.
  • Step 2: Inside the configuration file, locate the options section and make necessary changes as per your requirements. For example, you can specify your DNS server’s IP address and port.
  • Step 3: Create zone files for your domain(s) by adding configuration blocks to the named.conf file or separate files in the appropriate directory.

Step 4: Start and Enable the DNS Service

To start and enable the DNS service on your EC2 instance, follow these steps:

  • Step 1: Start the DNS service by running the command: sudo systemctl start named.service.
  • Step 2: Enable automatic startup of the DNS service on system boot by running: sudo systemctl enable named.

Ensure that there are no errors in your configuration files; otherwise, starting the service might fail. You can check for any syntax errors by running: sudo named-checkconf /etc/named.


You have successfully set up a DNS server on AWS. Now you can configure your domain registrar to use your new DNS server's IP address for your domain(s). Remember to update the DNS records accordingly.

By following these steps, you can easily configure and manage your own DNS server on AWS. It gives you full control over your domain's DNS resolution and allows you to customize it according to your needs.


Setting up a DNS server on AWS is a crucial step in managing your own domain names. With the help of Amazon EC2 and Bind, you can easily create a reliable and scalable DNS infrastructure. Remember to regularly update and secure your DNS server to ensure smooth operation and protection against potential threats.
