You setup every job in the cronjob module, then schedule a task (plesk) to run those cron jobs. I'm not sure what its called in cPanel.
Do you use Plesk or cPanel on your server?
You setup your server to run a scheduled task, like this in plesk. Im not sure how to do it in cPanel as I dont use it, but I'm sure it called something different, but works basically the same.
Changing the Script path and token to whatever the cron job module says to use.
Also, I put in 0,5,10,15 0 * * *, because I have my cron jobs running at midnight, and 0 mins, 5 mins, 10 mins, and15 mins, four jobs. You can set yours to just run at * * * * *, to run at all times if you want.
Then in the cron jobs module you simply setup like this...
See how I have each job running at midnight, and 0, 5, 10, and 15 mins? Again you can run them at anytime you see fit, if you use * * * * * in your servers task setup.
