From: Dries Buytaert Whenever ". path_uri() ."cron.php is accessed, cron will run: it checks for the jobs cron controls, and their periods in seconds. If a certain task wasn't executed in the last n seconds, where n is the period of that job, it will be executed. When all the executed commands terminate, cron is done. The recommended way to setup your cron system is to setup a Unix/Linux crontab that frequently visits ". path_uri() ."cron.php. Note that cron does not guarantee the commands will be executed at the specified interval. However, Drupal will try his best and run the crons as close to the specified intervals as possible. The more you visit cron.php, the more accurate cron will be. If your hosting company does not allow you to setup crontabs, you can always ask someone else to setup a crontab for you. After all, virtually any Unix/Linux machine with access to the internet can setup a crontab to frequently visit ". path_uri() ."cron.php. For the Unix/Linux crontab itself, use a browser like lynx or wget but make sure the process terminates: either use /usr/bin/lynx -source cron.php
or /usr/bin/wget -O /dev/null cron.php
. Take a look at the example scripts in the scripts
-directory and make sure to adjust them to your needs. A good crontab-line to run the cron-script once every hour would be: 00 * * * * /home/www/drupal/scripts/cron-lynx

using a browser; don't run it using command line PHP and avoid using localhost
or 127.0.0.1
, or some features won't work as expected. For all the environment variables to be correct; use a browser to access cron.php
