📘 Starting with Linux Commands

Navigating a new distribution can be daunting. Here is a unique breakdown of how to manage the "Big Three" families:

1. Package Management (The Vital First Step)

• Ubuntu/Debian: Use apt.

  • Update: sudo apt update && sudo apt upgrade

• RHEL/CentOS/Fedora: Use dnf (or yum).

  • Update: sudo dnf update

• Arch Linux: Use pacman.

  • Update: sudo pacman -Syu

2. Essential System Diagnostics

Regardless of the flavor, use these tools to identify issues:

• top or htop: View real-time resource usage.

• journalctl -xe: The gold standard for viewing system logs and finding service failures.

• df -h: Check for "No space left on device" errors immediately.

• netstat -tulpn: See which applications are listening on which ports.

3. Fixing Common Issues

• Permission Denied: Check ownership with ls -l and fix with chown or chmod.

• Service Won't Start: Use systemctl status [service] to read the specific error code.

• SSH Connection Refused: Ensure sshd is running and port 22 is open in the firewall (ufw status or firewall-cmd --list-all).

🏗️ Tips for a Successful Server Installation

1. Partition Wisely: Always separate /home, /var, and / to prevent log files from crashing the entire OS if the disk fills up.

2. SSH Security: Disable root login and password authentication immediately. Use SSH keys only.

3. Minimalism: Install only the packages you need. A smaller "attack surface" is a more secure server.

4. Documentation: Keep an operational runbook of every change you make to the configuration.
