This repository is a personal collection of useful DevOps commands, configurations, notes, and reusable snippets that I regularly use in real-world projects.
It is not a deployment project.
It is a practical reference library for everyday DevOps work.

As a developer working with servers frequently, I needed a centralized place to:
- Save reusable command references
- Avoid repeating research
- Keep production-tested solutions
- Share knowledge with others
This repo acts like my DevOps notebook.
All commands are shared for educational and reusable purposes.
Always review and test before applying on a production server.
Server environments differ.
