HostieR If you want to become an experienced sysadmin, start by learning Linux cause it’s the foundation of almost everything. Getting certifications like Linux Essentials and LPIC-1 is a great way to build your skills. Then, start self-hosting projects. Set up web servers like Apache or Nginx, manage databases like MySQL or MariaDB, and use Docker to simplify deployments.
Learn how networking works, understand things like TCP/IP, DNS, and HTTP, and use tools like Wireshark or tcpdump to analyze traffic. Spend time learning Linux security, set up firewalls, SSH hardening, kernel hardening, malware detection, auditing and monitoring, and much more. Figure out how to optimize server‘s performance as well.
Dive into hosting, optimizing, and securing WordPress sites. Learn about common issues like slow page loads, plugin conflicts, and database errors, and practice fixing them.
A home lab is super helpful for practice. Break things, fix them, and document what you learn. Dive into automation tools like Ansible, explore cloud platforms, and join online communities to connect with others.
Take it step by step, and over time, you’ll naturally grow into a solid sysadmin.
