OpenPanel Cron Troubleshooting Guide

This is a generic troubleshooting guide for OpenPanel cron jobs.

1) How cron works in OpenPanel​

In OpenPanel:

• Cron does NOT run directly on the host like traditional Linux crontab.
• Each user has their own cron container.
• Jobs run inside a specified container (e.g. openlitespeed, nginx, php, etc.).
• Cron jobs are defined in /home/USERNAME/crons.ini, not in /etc/crontab.

2) First diagnostic step --- run the command manually (is it even cron-related?)​

Before troubleshooting cron, always verify that the command itself works.

Access the user container terminal: https://openpanel.com/docs/panel/containers/terminal/#accessing-the-terminal

Inside the container, run your command manually, for example:

php -q /var/www/html/example.com/apps/console/console.php example-task

If this fails:​

• The issue is NOT cron
• Fix the error first (missing PHP extensions, wrong path, permissions, app config, etc.)

Only continue with cron troubleshooting after this works manually.

3) Check if the cron service is running​

Each user must have their own cron service active.

Check in OpenPanel: https://openpanel.com/docs/panel/advanced/services/

You should see a cron service running for the user.

If it is NOT running, start it manually (terminal):​

cd /home/USERNAME && docker --context=USERNAME compose up -d cron

4) Verify the cron file format (crons.ini)​

Check the user's cron file:

cat /home/USERNAME/crons.ini

A correct job looks like this:

[job-exec "example-job"]
schedule = @every 1m
container = openlitespeed
command = php -q /var/www/html/example.com/apps/console/console.php example-task

Common mistakes​

❌ Using host PHP path:

/usr/local/lsws/lsphp84/bin/php

✅ Use container PHP instead:

php

❌ Wrong container:

container = web

✅ Must match the actual container:

container = openlitespeed

5) Check cron execution logs (very important)​

OpenPanel provides per-job execution logs.

Cron job logs: https://openpanel.com/docs/panel/advanced/cronjobs/#logs

Look for: - Job started - Job failed - PHP errors - Permission denied - "Container not found"

6) Verify paths inside the container​

Paths inside Docker may differ from host paths.

Check inside the container:

docker --context USERNAME exec -it CONTAINER bash
ls /var/www/html

Confirm that:

/var/www/html/example.com/

actually exists inside the container.

7) Inspect the cron container logs​

If jobs still don't run, inspect the cron container itself:

docker --context USERNAME logs cron

Look for:

• Scheduler errors
• Container startup issues
• Permission problems

8) Validate correct container selection​

Make sure the job uses the correct container:

App type Likely container

OpenLiteSpeed + PHP openlitespeed or php Nginx + PHP nginx or php Standalone container CONTAINER_NAME

If you pick the wrong one → job fails.

9) Generic working cron template​

For an app hosted at example.com:

[job-exec "task-1"]
schedule = @every 1m
container = openlitespeed
command = php -q /var/www/html/example.com/apps/console/console.php task-1

[job-exec "task-2"]
schedule = @every 5m
container = openlitespeed
command = php -q /var/www/html/example.com/apps/console/console.php task-2

[job-exec "task-hourly"]
schedule = @hourly
container = openlitespeed
command = php -q /var/www/html/example.com/apps/console/console.php hourly

[job-exec "task-daily"]
schedule = @daily
container = openlitespeed
command = php -q /var/www/html/example.com/apps/console/console.php daily

10) Quick troubleshooting decision tree​

❓ "Cron doesn't run at all"​

Check: - Is cron service running? → Services page\

• Is there a cron container? → docker --context USERNAME ps | grep cron\
• Does /home/USERNAME/crons.ini exist?

❓ "Cron runs but command fails"​

Check: - Run manually inside container first\

• Check cron logs in OpenPanel\
• Check container logs

❓ "Cron runs but the app still complains"​

Check: - App logs inside /var/www/html/example.com/.../logs/\

• File permissions inside the container
