How to Register and Enable Red Hat Subscription, Repositories and Updates for RHEL 8.4 Server

Hey guys, In this tutorial post, After installation of Red Hat Linux 8.x, we will need to subscribe to the system with Red Hat Subscription Management (RHSM) to get updates, support, bug fixes, etc.

A subscription service has the function to recognize registered systems with the products installed on them. Without a subscription, you are not allowed to get an update, supports, and install repositories. If you want to update or install a package that is not associated with DNF or YUM command. You may get the bellow messages.

"This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Error: There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d"." 

Local Subscription Manager service tracks down the installed software products or packages, available and used subscriptions, and interacts with the Red Hat Customer Portal through tools like YUM.

To fix this issue first we have to create a Subscription account on Red Hat, and it's free to create. Here we are using the Red Hat subscription-manager to manage your subscriptions and repository through the terminal.
