I have installed the elysia cron module and setup the cron job. So far I'm running cron jobs mannually. And it is quite time consuming because I have other things to do than run cron every 2 hours. I read the handbooks on cron configurations, but didn't get much, since I'm not a PHP literate person.
How can I make my drupal run cron automatically??? So that I don't have to come back to my site every 2 hours.
You can use the crontab. Usually this can be accessed on your server by running crontab -e in the shell and then adding an entry to specify how frequently to update your site. For example,
0 * * * * wget -O - -q -t 1 http://{your_drupal_server}/cron.php
would run every hour. Replace {your_drupal_server} with the url of your server. The command assumes you have wget installed as well.
