1. Introduction to AWS Web Servers

AWS provides a vast selection of cloud services, and among the most popular is the Elastic Compute Cloud (EC2). EC2 allows users to rent virtual servers on which they can deploy applications, including web servers. This guide focuses on creating a basic web server using EC2, which will serve static web pages or run dynamic web applications.

2. Prerequisites

Before beginning, make sure you have:

  • A computer with internet access
  • Basic knowledge of command-line interfaces
  • An AWS account (we will guide you through creating one)
  • A simple website or HTML files ready to upload (optional)

3. Step 1: Create an AWS Account

If you don’t have an AWS account, follow these steps:

  1. Visit aws.amazon.com.
  2. Click on Create an AWS Account.
  3. Provide your email address, password, and AWS account name.
  4. Enter your contact information.
  5. Add payment information (AWS offers a free tier, but billing info is required).
  6. Verify your phone number.
  7. Choose the basic support plan (free).
  8. Log in to the AWS Management Console.

Once logged in, you’re ready to launch your first EC2 instance.

4. Step 2: Launch an EC2 Instance

An EC2 instance is a virtual server where you will install your web server software.

  1. From the AWS Management Console, search for EC2 and click to open the EC2 Dashboard.
  2. Click Launch Instance.
  3. Choose an Amazon Machine Image (AMI): Select Amazon Linux 2 AMI (HVM), SSD Volume Type. This is optimized for AWS and free-tier eligible.
  4. Choose an Instance Type: Select t2.micro (free tier eligible).
  5. Click Next: Configure Instance Details.
  6. Leave the defaults and click Next: Add Storage.
  7. Accept the default 8 GB storage and click Next: Add Tags.
  8. (Optional) Add a tag to name your instance, e.g., Key: Name, Value: MyWebServer.
  9. Click Next: Configure Security Group.

5. Step 3: Configure Security Groups

Security groups act as a virtual firewall.

  1. Create a new security group.
  2. Add the following inbound rules:
  • SSH: TCP port 22, Source: Your IP (for secure SSH access)
  • HTTP: TCP port 80, Source: Anywhere (0.0.0.0/0) to allow web traffic
  1. Review and click Review and Launch.
  2. Click Launch.
  3. You will be prompted to create or select a key pair:
  • Select Create a new key pair.
  • Name it, download the .pem file, and store it safely.
  1. Click Launch Instances.
  2. Click View Instances to see your running instance.

6. Step 4: Connect to Your EC2 Instance

To manage your EC2 instance, connect via SSH.

On Linux or macOS:

  1. Open your terminal.
  2. Set permissions for your .pem file:
   chmod 400 /path/to/your-key.pem
  1. Connect:
   ssh -i /path/to/your-key.pem ec2-user@your-instance-public-ip

On Windows:

Use an SSH client like PuTTY:

  1. Convert .pem to .ppk using PuTTYgen.
  2. Open PuTTY and enter your instance’s public IP.
  3. Load the .ppk file under SSH > Auth.
  4. Connect as user ec2-user.

7. Step 5: Install a Web Server (Apache)

Once connected, install the Apache web server:

  1. Update packages:
   sudo yum update -y
  1. Install Apache:
   sudo yum install httpd -y
  1. Start the Apache service:
   sudo systemctl start httpd
  1. Enable Apache to start on boot:
   sudo systemctl enable httpd
  1. Confirm Apache is running:
   sudo systemctl status httpd

8. Step 6: Upload Your Website Content

You can upload files using SCP or directly create content on the server.

Upload using SCP:

From your local machine, run:

scp -i /path/to/your-key.pem /path/to/index.html ec2-user@your-instance-public-ip:/var/www/html/

Alternatively, create a simple index.html:

On the EC2 instance:

sudo echo "<html><h1>Welcome to My AWS Web Server</h1></html>" > /var/www/html/index.html

9. Step 7: Configure Elastic IP for Static Addressing

By default, your instance’s public IP can change after reboot. To keep a fixed IP:

  1. In the AWS Console, go to EC2 > Network & Security > Elastic IPs.
  2. Click Allocate Elastic IP address.
  3. Select the new Elastic IP and click Actions > Associate Elastic IP address.
  4. Choose your instance and associate.

Use this Elastic IP to access your server reliably.

10. Step 8: Test Your Web Server

Open your browser and navigate to your instance’s public IP or Elastic IP:

http://your-elastic-ip/

You should see your website or the default Apache page.

11. Optional: Set Up a Domain Name with Route 53

To use a custom domain:

  1. Register a domain via Route 53 or another registrar.
  2. Create a hosted zone in Route 53.
  3. Add an A record pointing your domain to your Elastic IP.
  4. Update your domain registrar’s name servers to those provided by Route 53.
  5. Wait for DNS propagation.

Your website will now be accessible via your domain name.

12. Conclusion

Creating a web server on AWS is straightforward and scalable. This guide covered launching an EC2 instance, securing it, installing Apache, deploying your website, and configuring a static IP. AWS offers immense flexibility to expand your server capabilities, add databases, and integrate with many services as your project grows.

By mastering these foundational steps, you are well on your way to leveraging the power of AWS cloud computing for your web applications. Happy hosting!
