Summary

In this chapter, we have gone through the admin parts of software management in a RHEL 8 system, from subscriptions to installation, to modularity, and other miscellaneous tips.

All the system patching, updating, and management in RHEL relies on yum/dnf and simplifies managing dependencies, installing the right versions of software, and distributing it in isolated environments. This is one of the tasks more common for system administrators and should be understood completely.

For the Red Hat Certified Engineer level, a more in-depth look will be required, including creating RPM packages, which are very useful to manage, maintain, and distribute internally produced software in your own environments leveraging the experience and tools that Red Hat provides.

Now that our systems are up to date, let's move on to learn how to manage them remotely in the upcoming chapter.
