📖 Essential Commands & Quick Fixes

Starting with Linux requires a firm grasp of the package manager and service controller unique to each distribution.

1. Universal Package Management 📦

2. Fixing Common Issues 🔧

• Service Won't Start: Check the status and logs immediately.

  • sudo systemctl status

  • journalctl -xe

• Disk Space Exhaustion: Find large files quickly.

  • df -h (check mount points)

  • du -sh /* | sort -h (locate the heaviest directories)

• Permission Denied: Fix ownership issues.

  • chown -R user:group /path/to/directory

💡 Tips for a Successful Server Setup

1. Use SSH Keys: Disable password-based root login immediately to prevent brute-force attacks.

2. Separate Partitions: Use separate partitions for /var, /home, and /tmp to prevent system crashes if logs or user data fill the disk.

3. Enable Swap: Even on high-RAM systems, a small swap file helps manage memory spikes gracefully.

4. Documentation: Keep an updated Runbook of every manual change made to the configuration.
