Background work on cPanel.
WHAT THE SCHEDULER NEEDS
A single cron entry, running every minute, invoking the scheduler command.
WHAT TO SPECIFY IN THE CRON ENTRY
The full path to the correct PHP version The full path to the application Output redirected somewhere
WHY FULL PATHS
Cron runs with a minimal environment and inherits nothing.
WHAT TO CHECK
That the entry runs, by scheduling something that writes to a log.
WHAT QUEUES NEED
A worker consuming jobs.
WHAT SUITS SHARED HOSTING
Running the worker for a limited time, started by the scheduler, rather than a persistent process.
WHY
Persistent processes are frequently restricted and consume resources continuously.
WHAT TO CONFIGURE
A limit on how long a worker runs A limit on attempts per job Failed job recording
WHAT TO MONITOR
Queue length Failed jobs Whether the scheduler is running at all
WHAT TO AVOID
A worker holding stale code after deployment.
WHAT TO DO ABOUT THAT
Restart workers as part of deployment.
