Linux Server Administration
Welcome to the Linux Server section of the IT Manual. This directory serves as the knowledge base for the various Linux distributions used within our infrastructure.
Each sub-directory contains specific documentation for that ecosystem, including installation guides, package management standards, and service configuration (DNS, Web, Storage, etc.).

📂 Directory Structure Strategy
Inside each distribution folder, you will generally find documentation covering the following lifecycle stages:
- Setup & Install: Base installation, partitioning, and initial user creation.
- Network Configuration: Static IP assignment, DNS settings, and hostname configuration.
- Package Management: How to update and install software (e.g.,
apt,dnf,zypper). - Services: Specific guides for roles like Web Server (Apache/Nginx), Database, or File Sharing.

📝 Contribution Guidelines
- Version Specificity: When writing a guide, please specify the version used (e.g., Ubuntu 22.04 LTS or Debian 12).
- Root vs Sudo: Clearly indicate if commands require root privileges (usually denoted by
#for root or$for user).
