Cron job, the first thing must be done for your Drupal site
Why? Might you ask?
Running Cron will keep your site operating optimally.
Cron a scheduler that automates system tasks.
. Rotate your log and statistical data.
. Do a number of behind-the-scenes cleanup functions like clearing the sessions table.
. Many modules (like RSS feed) also schedule tasks via Cron, some modules may not behave as designed if Cron does not run.
On a small site, you can execute Drupal cron.php manually via http://yoursite.com/cron.php but it is better to do it via Cron.
Set it up once and out of your mind and out of your sight!
How to setup Cron? Very easy!
Use these steps:
Note: My host have some kind of security that block the command so I have to add space to get around it.
COMMAND is "w g e t"
. Login to your site via ssh
. At the command prompt, type "crontab -e"
. In the editor buffer type (no quote): "*/15 * * * * COMMAND -q -t 1 http://yoursite.com/cron.php"
. Hit control-X to exit and "Y" to save and "enter" to confirm
What does that line do?
It means run this task once a day, in every 15 minutes using "w g e t" command with "quiet mode" and "try 1 time" with the URL of "http://yoursite.com/cron.php"
