While package managers differ, the logic remains consistent.
| Task | Debian/Ubuntu (APT) | RHEL/CentOS/Rocky (DNF) | Arch Linux (Pacman) |
| Update System | sudo apt update && upgrade | sudo dnf upgrade | sudo pacman -Syu |
| Install Package | sudo apt install [pkg] | sudo dnf install [pkg] | sudo pacman -S [pkg] |
| Check Services | systemctl status [svc] | systemctl status [svc] | systemctl status [svc] |
| Network Info | ip addr show | ip addr show | ip addr show |
Permission Denied: Always check ownership with ls -l and adjust using chmod or chown. Avoid using 777 permissions; stick to the principle of least privilege.
Service Won't Start: Use journalctl -u [service_name] -xe to view the specific error logs.
Disk Full: Identify large files quickly with du -sh /* | sort -h.
An expert Linux Administrator relies on these specialized tools:
htop / btop: For interactive process monitoring.
nmap / netstat: For network discovery and port auditing.
tcpdump / Wireshark: For deep packet inspection.
strace: To debug system calls and signal deliveries.
vim / nano: Efficient command-line text editing.
Documentation: Maintain a "Runbook" for every server detailing its unique configurations.
Statelessness: Move toward immutable infrastructure where possible (e.g., Docker) to make recoveries instant.
Monitoring First: Never put a server into production without active monitoring and alerting (Zabbix, Prometheus, or Nagios).
SSH Security: Always disable root login and use SSH Key authentication instead of passwords.
