This category focuses on real world Linux server administration for developers, freelancers, and small teams who have to manage their own infrastructure. You will find tutorials for working on popular distributions like Amazon Linux 2023, Ubuntu, and Debian, along with practical shell tips that make everyday tasks faster. Articles cover user and group management, systemd services, log rotation, backups, SSH hardening, and the kind of command line workflows that keep servers clean and predictable.

I also dig into troubleshooting and performance tuning so you can confidently debug slow or misbehaving servers. Topics include reading system logs, inspecting running processes, understanding load averages and memory usage, and using tools like top, htop, journalctl, and strace when things get weird. Many guides are based on actual incidents from production environments, so you can learn from real issues instead of contrived examples.

As you move through the Linux category you will build a toolbox that applies anywhere, whether you are managing a single VPS, multiple EC2 instances behind a load balancer, or a home lab. The goal is to help you become comfortable on the command line, understand what your system is actually doing, and make changes in a safe, repeatable way.
