Hey everyone! I'm trying to understand the relationship between RHEL and Fedora. As I understand it, RHEL is basically a version of Fedora that has been thoroughly tested and approved for professional use, right? If that's the case, does it mean that software designed for RHEL will run smoothly on Fedora? I'm particularly interested in CGI software that often suggests using RHEL or Rocky. Apologies if I'm a bit confused; I'm here to learn!

Generally speaking, Fedora and RHEL aren’t directly interchangeable. While RHEL is heavily based on Fedora, it also prioritizes stability, so software designed for RHEL doesn’t always work flawlessly on Fedora. If you specifically need RHEL compatibility, I'd recommend looking into installing RHEL or using Rocky Linux instead, as they are designed to be bug-for-bug compatible with RHEL.
You can definitely use Fedora, but mixing it with RHEL software isn’t advisable. Each distribution has its own package management system, and they’re set up differently for a reason. If things are running well on Fedora, don’t stress too much about it! Many folks don’t really grasp what 'stable' means in the Linux world and sometimes break things by upgrading without needing to.
Short answer: No, they’re not completely compatible. Long answer: It depends on the specific software. RHEL is built for long-term support and stability, while Fedora often has cutting-edge features that might not be stable yet. So, software made specifically for a certain version of RHEL might break on a newer version of Fedora.
RHEL pulls some packages from Fedora, treating it as a testing ground, so while they’re related, software isn’t guaranteed to work across them. If your goal is full RHEL compatibility, you might want to get a free developer account for RHEL or consider using Rocky Linux, which aims for complete compatibility with RHEL.
