The guide shows how to install and run Redis on Fedora 36 using the distribution’s official packages, avoiding manual compilation that can cause SELinux or library issues. After installing with dnf, you enable and start the service via systemctl enable --now redis.service so it persists across reboots. A quick sanity check with redis-cli ping should return “PONG”, and any connection problems are diagnosed through systemctl status and SELinux logs. Optional configuration tweaks, such as enabling persistence or adjusting socket policies after updates, are also explained.

The guide explains how to add a robust web‑application firewall to Ubuntu 22.04 by installing Apache, the ModSecurity engine (libmodsecurity3), and the OWASP Core Rule Set from the official repositories, then enabling the security2 module and restarting the service. It walks through configuring ModSecurity to load the CRS, switching the rule engine from “DetectionOnly” to active blocking, and testing the setup with a simple PHP script that should trigger a 403 response for malicious input. Finally, it advises fine‑tuning or disabling noisy rules by editing the CRS configuration and reminds you to keep the rule set updated and monitor logs for new threats.

The guide explains how to install Microsoft PowerShell on AlmaLinux 8 by first importing Microsoft’s GPG key and creating a custom yum repository file that points to the official package source. With the repository in place, you can install the “powershell” package using dnf and then launch it with the pwsh command to verify a successful setup. It also shows how to make PowerShell your default login shell via chsh if desired. Finally, the article warns about common issues such as missing repository URLs, GPG‑key errors, and SELinux denials, offering quick fixes for each.

This guide walks you through replacing AlmaLinux 8’s default Nouveau driver with Nvidia’s proprietary Linux driver, starting with disabling Secure Boot so unsigned kernel modules can load. It then adds the ELRepo repository, installs the matching kernel‑development packages and the akmod‑nvidia DKMS framework, and blacklists Nouveau before rebuilding the initramfs to prevent conflicts. After those preparations you install the pre‑built Nvidia driver (and optionally CUDA) from ELRepo, reboot, and verify that the GPU is active with nvidia-smi or Xorg logs. The article also notes common pitfalls—such as missing kernel‑devel packages causing “invalid module format” errors—and offers quick fixes to keep the driver working across kernel updates.

The guide walks you through adding the elementary community COPR repository to Fedora 36 and then installing the “Pantheon Desktop” group together with the elementary icon theme and wallpapers. It shows how to replace GNOME’s default GDM with LightDM (or keep GDM) and select Pantheon as the session at the login screen. Optional clean‑up steps remove leftover GNOME packages and a tweak disables Gala’s VSync for smoother performance on older GPUs. After a reboot, you end up with a fully functional Pantheon desktop—complete with its dock, top panel, and theme—ready for further customization.
