📘Command Mastery & Troubleshooting

To manage a diverse environment, you must understand the nuances between package managers.

1. Quick Start Commands by Distribution

Task	Debian/Ubuntu (apt)	RHEL/Rocky/Fedora (dnf)	Arch Linux (pacman)
Update System	`sudo apt update && sudo apt upgrade`	`sudo dnf update`	`sudo pacman -Syu`
Install Package	`sudo apt install [package]`	`sudo dnf install [package]`	`sudo pacman -S [package]`
Check Services	`systemctl status [service]`	`systemctl status [service]`	`systemctl status [service]`

2. Fixing Common "Breaking" Issues

Permission Denied: Don't just chmod 777. Use ls -l to check ownership and apply chown user:group to maintain security.
Dependency Hell: On Debian systems, use sudo apt --fix-broken install to repair interrupted installations.
Disk Space Exhaustion: Use du -sh /* to find large directories and journalctl --vacuum-time=3d to clear old system logs.

🚀 Tips for a Successful Server Installation

Partition Wisely: Always separate /var, /home, and / to prevent a log explosion from crashing the entire system.
SSH Hardening: Immediately disable root login and switch to SSH key-based authentication. Change the default port 22 to a non-standard port to reduce bot attacks.
Documentation: Maintain an operational runbook. If a configuration change is made, it should be reflected in your Ansible playbooks or a simple markdown file.
