Essential Commands Across Distros

 

Starting with a new distribution can be daunting. I’ve compiled this quick-reference guide to help you navigate the different package managers and system basics.

 

 

1. Package Management (The Big Four)

 

 

Task Ubuntu/Debian (APT) RHEL/CentOS/Alma (DNF) Arch Linux (Pacman) openSUSE (Zypper)
Update Lists sudo apt update sudo dnf check-update sudo pacman -Sy sudo zypper ref
Install App sudo apt install sudo dnf install sudo pacman -S sudo zypper in
Full Upgrade sudo apt upgrade sudo dnf upgrade sudo pacman -Syu sudo zypper up
Remove App sudo apt remove sudo dnf remove sudo pacman -R sudo zypper rm

 

 

 

2. System Diagnostics (Universal)

 

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

  • Monitor Resources: htop or top (See what's eating your RAM/CPU).

  • Check Logs: journalctl -xe (The first place to look when a service fails).

  • Network Status: ip a (To find your IP address) or ss -tulpn (To see open ports).

 

 

 


 

 

🆘 Fixing Common Linux Issues

 

 

In my experience, 90% of Linux "disasters" stem from a few recurring issues. Here is how I approach them:

 

  • 🔒 SSH Login Failures: Usually caused by incorrect permissions on the .ssh folder (should be 700) or the authorized_keys file (should be 600).

  • 💾 Disk Full: Use du -sh /* | sort -h to find which directory is consuming space. Often, it's /var/log getting bloated.

  • ⚙️ Service Won't Start: Use systemctl status followed by journalctl -u to see the specific error line.

  • 🌐 DNS Issues: If you can ping IPs but not names, check /etc/resolv.conf. Switching to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) often fixes it.

 

 

 


 

 

🚀 Tips for a Successful Server Setup

 

 

A successful installation isn't just about clicking "Next." Follow these expert principles:

 

 

  1. Hardening from Minute One: Disable Root SSH login and change the default port. Always use SSH keys instead of passwords. 🛡️

  2. LVM is Your Friend: Always use Logical Volume Management (LVM). It allows you to resize partitions later without reformatting.

  3. Automate Updates: For Debian/Ubuntu, use unattended-upgrades. For RHEL-based, use dnf-automatic. Safety first!

  4. Monitoring & Backups: Never go live without a 3-2-1 backup strategy (3 copies, 2 media types, 1 offsite).

  5. Documentation: Document every custom configuration change in a /root/README file. Future-you will thank me.
