Click on “Launch Instance” to begin creating a new EC2 instance. This process involves selecting the appropriate configurations for your server.

Amazon Machine Image (AMI): Choose linux based image as your base image.I would recommend  "Amazon Linux 2" is optimized for running on AWS and provides a stable, secure, and high-performance execution environment.

Instance Type: Select an appropriate instance type based on your needs. For this tutorial, the “t2.micro” instance type is sufficient.

Key Pair: Choose create a new one or an existing key pair. This key pair will be used for SSH access to your instance. Ensure you download the key pair file (.pem) and keep it secure.

Security Group: Configure the security group to allow SSH (port 22) and HTTP (port 80) traffic. This ensures that you can connect to the instance and that the web server is accessible from the internet.

Finally review the configurations and click “Launch Instance” Your EC2 instance will be created and available in a few moments.

Step 2 : Connect to Instance using SSH

Once the instance is running, SSH into it using your terminal or SSH client. First use the following command on terminal to enable permission to private key file.

chmod 400 "<keyname.pem>"

Then use following command, replacing <key-pair-file> with the path to your key pair file, <username> with your instance username and <instance-public-IP> with your instance's public IP address or public DNS:

ssh -i "<key-pair-file>" <username>@<instance-public-IP or DNS>

In my instance I used public IP,

ssh -i "test_key.pem" ec2-user@<xxx.xxx.xxx.xxx>

Step 3 : Update All Packages

After logging in, it’s important to update all installed packages to ensure your instance is running the latest software versions. Run the following commands:

sudo yum update && sudo yum upgrade

This command updates the package index and ensures that you have access to the latest versions of the software available in the repository.

Step 4 : Install and Enable Nginx Web Server

Next to install Nginx on instance, run the following command:

sudo yum install nginx

you can check weather the Nginx web server installed with command:

sudo yum list install nginx

After installation, enable and start the Nginx web server with command:

sudo systemctl enable nginx

Step 5 : Verify the Nginx Web Server works using Public IP

To verify that your Nginx web server is running, open your web browser and enter your instance’s public IP address. If Nginx is installed and running correctly, you should see the default Nginx welcome page.

So you have successfully installed Nginx on your EC2 instance. I will now show you how to create a sample HTML file for your website using nano.
So you need to navigate to the document root directory of default Nginx page. 

Once you run the following command:

sudo nano /usr/share/nginx/html/index.html

It will open the nano text editor as following

Add your custom HTML content, save the file and exit the editor. Refresh your browser to view your custom webpage!

So this is it ! Hoping the above steps great guide to deploying Nginx and sample files on AWS instance. Also, I think this guide will help to deploy other web servers like Apache Web server.
