📖 Starting with Linux Commands

Navigating a new distribution can be daunting. Here is my unique "Quick-Start" guide for the most common environments:

1. Package Management (The "Big Three")

• Ubuntu/Debian: Use apt.

  • Update system: sudo apt update && sudo apt upgrade -y

• RHEL/Alma/Rocky: Use dnf.

  • Install package: sudo dnf install [package_name]

• Arch Linux: Use pacman.

  • Sync and Update: sudo pacman -Syu

2. Fixing Common Issues

• Permission Denied: Instead of 777, use chown to fix ownership: sudo chown -R user:group /path/to/folder.

• Service Won't Start: Check the logs immediately: sudo journalctl -u [service_name] -e.

• Disk Full: Find what’s eating space: du -ah / | sort -rh | head -n 10.

🚀 Tips for a Successful Server Setup

1. Minimize the Install: Always start with a "Minimal Install" to reduce the attack surface. You can always add packages later.

2. SSH Hardening: Change the default port 22, disable root login, and always use SSH keys instead of passwords.

3. Logical Volume Management (LVM): Always use LVM during partitioning. It allows you to resize disks later without reformatting.

4. Time Sync: Ensure chrony or ntp is running. Inconsistent system clocks cause havoc with logs and databases.
