How to Register Your RHEL 9 System (The Simple Way)...

Publish Date: Apr 26
2 0

If you're running RHEL 9 on VirtualBox (or anywhere else), one of the first things you'll want to do is register your system with Red Hat. Registering gives you access to official repositories, security patches, updates, and all the good stuff that keeps your system stable and secure.

Let me show you a quick and simple guide to get it done.

Step 1: Register Your System 

subscription-manager register --username <your_redhat_username> --password <your_redhat_password>
Enter fullscreen mode Exit fullscreen mode

Replace <your_redhat_username> and <your_redhat_password> with your Red Hat account credentials. (If you don't have an account yet, you can create one for free at Red Hat.

Once it is successfully registered, you should get this prompt.

Step 2: Refresh Your Subscription

After successfully registering, refresh the subscription manager:

subscription-manager refresh
Enter fullscreen mode Exit fullscreen mode

refresh

Step 3: Verify Your Registration

You can check if your system is properly registered by running:

subscription-manager identity
Enter fullscreen mode Exit fullscreen mode

or

subscription-manager status
Enter fullscreen mode Exit fullscreen mode

This will confirm that your system is recognized by Red Hat.

Step 4: Attach an Available Subscription

To automatically attach a subscription (instead of manually choosing one):

subscription-manager attach --auto
Enter fullscreen mode Exit fullscreen mode

Step 5: Update and Install Essential Packages

Now that you're registered and ready to roll, it's a good idea to update your system and install some basics:

# Update package information
dnf update
Enter fullscreen mode Exit fullscreen mode 
# Install Vim and enhanced version
dnf install vim
dnf install vim-enhanced
Enter fullscreen mode Exit fullscreen mode 
# Perform system upgrade
dnf upgrade
Enter fullscreen mode Exit fullscreen mode 
# Check for available updates
dnf check-update
Enter fullscreen mode Exit fullscreen mode

This ensures your system has the latest updates and access to Red Hat's official repositories.

Here are some snapshots of the update process...

Summary

Now your RHEL 9 system is fully registered, updated, and ready for action. Whether you're setting up a new project, learning Linux, or preparing for certifications, having a properly registered system is key to a smooth experience.

Happy learning and building!

If you're using a developer subscription, remember that RHEL systems need to check in at least once every 30 days to maintain their registration status.
