🌐 Hosting a Simple Webpage
Here’s how you can host a basic index.html file on your EC2 instance.
Step 1: Install a Web Server
Log into your EC2 instance via SSH and run the following commands to install a web server:
# Update the package manager
sudo apt update
# Install Apache2
sudo apt install apache2 -y
# Start Apache2 service
sudo systemctl start apache2
# Enable Apache2 to start on boot
sudo systemctl enable apache2
Step 2: Create Your Webpage
Navigate to the default web server directory and create an index.html file:
# Navigate to the default directory
cd /var/www/html
# Create or edit the index.html file
sudo nano index.html
Add the following content to your index.html file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Welcome to My Webpage</title>
</head>
<body>
<h1>🚀 Welcome to My First AWS EC2 Hosted Webpage!</h1>
<p>This is a simple webpage hosted on an EC2 instance.</p>
</body>
</html>
Save and exit (Ctrl+O, Enter, Ctrl+X).
Step 3: Open Your Webpage
- In your browser, navigate to:
http://<Public_IP_of_EC2_Instance>
You should see your index.html webpage live! 🎉
🔒 Security Best Practices
- Use Security Groups: Restrict inbound traffic to only required ports.
-
Key Management: Keep your
.pemfile secure. - IAM Roles: Assign least privilege roles to your instances.
🎉 Conclusion
With this guide, you’ve:
- Launched your first EC2 instance.
- Installed a web server.
- Hosted your first
index.htmlwebpage.
