Magento – Can’t get cron to work

cronsitemaps

I try to set up cron to generate my site map.

I defined the google sitemap in catalog > google sitemap.
I also defined the system > configuration > catalog > google sitemap generation to every day

I then configured cron in system > configuration > system > cron as follow :

enter image description here

As no update are made on my sitemap files, I implemented the following php
php cron job monitor

But no tasks are displayed….

Furthermore, when I do a crontab -l I have i got an error saying "No crontab for user"

Could you help me on that please?

It looks like you need to setup the crontab for the user on your server.

Magento provides some generic instructions on how to do this.

Basically you should add the following lines to your crontab file.

MAILTO=your.user@your.server.com

*/5 * * * *  /bin/sh /path/to/your/magento/cron.sh

Magento – How are dynamic cronjobs inserted into cron_schedule

These kind of cronjobs have a backend model that is called when the cron settings are called. This model inserts the cron job run time in core_config_data and the cron schedule reads it from there.
Let's take as example the sitemap cron. The field 'frequency' has this backend model (see app/code/code/Mage/Sitemap/etc/system.xml):

<backend_model>adminhtml/system_config_backend_sitemap_cron</backend_model>

When the frequency is saved (and the rest of the fields with it) this method is called: Mage_Adminhtml_Model_System_Config_Backend_Sitemap_Cron::_afterSave().
This inserts in the table core_config_data the cron expression with this path crontab/jobs/sitemap_generate/schedule/cron_expr.
This value is read in Mage_Cron_Model_Observer::_generateJobs and added to the cron_schedule

Cron Job Runs Twice – How to Fix Daily Cron Job Issue

You should actually be using the cron.sh script found packaged with magento. This does a ps | grep call to make sure the Magento cron isn't already running. If it is then it doesn't run. If you do this then you will never have worry about cron tasks overlapping.

Your cron setup would look something like this.

*/5 * * * * /yoursite/cron.sh

If you package this up with the AOE_Scheduler extension you'll be onto a winner.
