In this post, I’ll walk you through launching a Red Hat Enterprise Linux 9 (RHEL9) virtual machine using Amazon EC2. This setup is beginner-friendly, using free-tier eligible services. This setup allows you to practice Linux and cloud skills; this may also be an option when a physical test machine is not available.

🧾 What You’ll Need

  • An AWS Free Tier account
  • Terminal access (CloudShell)
  • A basic understanding of SSH

🪟 Step 1: Launch an EC2 Instance

  1. Log into the AWS Management Console
  2. Navigate to the EC2 Dashboard and click Launch Instance
  3. Enter a name (e.g., rhel9-vm)
  4. Under Amazon Machine Image (AMI), select:
    • Red Hat Enterprise Linux 9 (HVM), SSD Volume Type
    • Found under the Quick Start AMIs
    • ✅ Marked as Free Tier eligible

⚙️ Step 2: Configure Instance Details

  • Instance type: t2.micro (Free Tier)
  • Key pair:
    • Create a new one or use an existing .pem file
    • Make sure to download and save it securely
  • Storage: 10 GiB is the default and works fine for this setup
  • Network settings: Use the default VPC or your preferred subnet

🔐 Step 3: Set Inbound Security Group Rules

Make sure the instance allows SSH access:

This should be default, but here are edit steps if needed:

  1. Under Security Group Settings, click Edit inbound rules
  2. Add a rule with the following:
    • Type: SSH
    • Protocol: TCP
    • Port Range: 22
    • Source: My IP (recommended)

This is required to access your VM via SSH.

🌐 Step 4: Connect to Your Instance via SSH

Once your instance state is running, do the following:

  1. Locate the Public IPv4 address in the EC2 dashboard
  2. In your terminal, navigate to the folder with your .pem file

  3. Change the permissions to secure the key:

    chmod 400 your-key.pem

  4. Connect to your instance:

    ssh -i your-key.pem ec2-user@your-public-ip

⚠️ Without the correct permissions on the .pem file, SSH will throw a warning and refuse to connect. Use chmod 400 to fix this.

🖥️ Step 5: Verify OS and Update the System

Once logged in, verify the RHEL version:

cat /etc/redhat-release

You should see:

Red Hat Enterprise Linux release 9.x (Plow)

Snippet:

Verify_System

Update installed packages:

sudo dnf update -y

📌 Key Reminders

  • ✅ RHEL 9 is available in Quick Start AMIs and is Free Tier eligible
  • 🔐 Inbound security group rules must allow SSH (TCP on port 22)
  • 🔑 Set file permissions with chmod 400 before connecting via SSH
  • 👤 Use the default EC2 username: ec2-user

🧠 What I Learned

  • Launching a Linux instance on AWS is straightforward and quick
  • Red Hat Enterprise Linux 9 is a stable and powerful system
  • Understanding security group settings is key for successful connections

🔧 Next Steps

I’ll be using RHEL9 to:

  • Practice Linux terminal commands
  • Explore system-level configurations and services
