🚀 Day 6 of DevOps + Cloud – Shell Scripting, AWS Services & My First Web Server

🖥 Today’s Journey

Today was all about automation, AWS services overview, and hosting my first webpage on an EC2 instance. It felt like combining theory + practice in the best way.

1️⃣ Shell Scripting for Automation

Instead of typing the same commands again and again, I learned how to write shell scripts. Example:

#!/bin/bash
echo "Updating system..."
sudo yum update -y

echo "Creating a directory..."
mkdir myapp && cd myapp

echo "Creating a test file..."
echo "Hello DevOps 🚀" > test.txt
cat test.txt

💡 This is the starting point of automation → tomorrow it can grow into installing apps, deploying servers, or CI/CD pipelines.

2️⃣ Common AWS Services Every DevOps Engineer Must Know

I explored why these AWS services matter:

• EC2 (Elastic Compute Cloud): Virtual machines in the cloud.

• S3 (Simple Storage Service): Store & retrieve any amount of data.

• RDS (Relational Database Service): Managed databases without worrying about backups & patches.

• Lambda: Run functions without managing servers (serverless).

• CloudFront: A global CDN that makes content load faster worldwide.

• IAM (Identity & Access Management): Control who can do what on AWS.

3️⃣ IAM Users vs Root User

• Root User → The “super admin” of AWS. Full power. Should be used only once to create IAM users.

• IAM User → Safer. You give limited permissions (like “read-only S3” or “EC2 admin”).
  👉 Best practice: Don’t use root for daily tasks — always work with IAM users.

4️⃣ Hosting My First Webpage on AWS EC2

Steps I followed:

1. Connect to EC2 instance (Amazon Linux).

2. Install Apache Web Server:

    sudo yum install httpd -y
    sudo systemctl start httpd
    sudo systemctl enable httpd
   

3. Create a simple HTML page:

    echo "<h1>Welcome to Apache Web Server on Amazon Linux 🎉</h1>" | sudo tee /var/www/html/index.html
   

4. Open instance public IP in browser:
   http://<your-ec2-public-ip>

✅ My first webpage was live on AWS!
