🧹 CyberPanel Server Cleanup: Logs, Dumps, Backups in One Shot
📘 Introduction
This guide is your go-to reference for keeping a CyberPanel + OpenLiteSpeed Linux server lean, fast, and clean. Over time, logs, backups, and core dumps pile up — wasting space, slowing down services, or even crashing the server.
Use these commands and tips to clean:
- 🔧 Web server logs
- 💥 Crash/core dumps
- 📦 Backups
- 📑 System journal logs
📂 Web Server Logs Cleanup (/usr/local/lsws/logs)
📍 Location:
/usr/local/lsws/logs/
🧾 Files:
access.log,error.log,stderr.log.log.*,.gz,.bak(rotated logs)
🧹 Clean all logs:
rm -f /usr/local/lsws/logs/*.{log,log.*,gz,bak}
💥 Core Dump Cleanup (/etc/coredumps)
📍 Location:
/etc/coredumps/
🧠 What are they?
Core dumps are memory snapshots saved when an app crashes. Useful for debugging but take up huge space.
🧹 Keep only the latest 5 dumps:
ls -lt /etc/coredumps | tail -n +6 | awk '{print $9}' | xargs -I{} rm -f /etc/coredumps/{}
🛑 Disable dumps (recommended):
echo 'kernel.core_pattern=|/bin/false' >> /etc/sysctl.conf
sysctl -p
echo '* hard core 0' >> /etc/security/limits.conf
📦 Backup Folder Cleanup (/backup)
📍 Location:
/backup
🗃️ What’s inside?
CyberPanel stores scheduled and manual backups here — easily fills disk space.
🧹 Keep only the 2 most recent backups:
ls -dt /backup/* | tail -n +3 | xargs -I{} rm -rf {}
🗂️ Systemd Journal Cleanup
📍 Location:
/var/log/journal/
🧠 What is it?
System log storage managed by systemd. It can quietly consume multiple gigabytes.
🧹 Delete logs older than 1 day:
journalctl --vacuum-time=1d
⚙️ Full Cleanup (One-Line Command)
💡 Run this to clean everything in one go:
ls -lt /etc/coredumps | tail -n +6 | awk '{print $9}' | xargs -I{} rm -f /etc/coredumps/{} && rm -f /usr/local/lsws/logs/*.{log,log.*,gz,bak} && ls -dt /backup/* | tail -n +3 | xargs -I{} rm -rf {} && journalctl --vacuum-time=1d
