📖  Starting with Linux Commands

Navigating different distributions requires knowing the specific package managers. Here is a quick cheat sheet:

1. Package Management (The Big Three)

• Ubuntu/Debian (APT): sudo apt update && sudo apt upgrade — Refresh and update system.

• RHEL/AlmaLinux/Fedora (DNF): sudo dnf install [package_name] — Install new software.

• Arch Linux (Pacman): sudo pacman -Syu — Sync and update the entire system.

2. Essential Troubleshooting Commands

• Check Resource Usage: top or htop (visual interface).

• Check Disk Space: df -h (human-readable format).

• Analyze Logs: journalctl -xe (the gold standard for systemd debugging).

• Network Connectivity: ss -tulpn (shows active ports and services).

🛠️ Fixing Common Linux Issues

1. "Permission Denied": 🔐

   • Fix: Check ownership with ls -l. Use chown user:group filename or chmod 644 filename to correct permissions.

2. Full Disk Drive: 💽

   • Fix: Run du -sh /* to find large directories. Clean up logs in /var/log or clear package caches (apt clean or dnf clean all).

3. Broken Dependencies: ⛓️

   • Fix: On Debian/Ubuntu, use sudo apt --fix-broken install.

🚀 Tips for a Successful Server Setup & Installation

I recommend following these "Golden Rules" for every new installation:

1. Minimal Installation: 🏗️ Always start with a "Minimal" or "Net-Install." Only install the packages you absolutely need. This reduces the "attack surface" for hackers.

2. SSH Hardening: 🔑 Disable root login (PermitRootLogin no) and password authentication. Always use SSH Keys for access.

3. Use a Firewall from Day One: 🔥 Enable ufw (Ubuntu) or firewalld (RHEL) immediately. Close all ports except those strictly necessary (e.g., 22, 80, 443).

4. Automate Updates: 🤖 Setup unattended-upgrades (Debian) or dnf-automatic (RHEL) for security patches to ensure you are never vulnerable to known exploits.

5. Time Synchronization: ⏱️ Ensure Chrony or NTP is configured. Accurate system time is critical for logs, security tokens, and database integrity.
