setting up cron to run php files

[mmarif4u]

Hi to all.
I want to run a php file through crontab.
I know some basic things about cron.but need some more details.
I have a dedicated server for one of my client running Debian on it.
I want to run a php script where it will update some database tables in a 10 or 5 min interval of time. the best bet here is to run that script through crontab.
i know it will be something like this:

10 * * * * /usr/local/bin/php /var/www/html/cron.php

but now how could i setup this cron file to run properly.
And is the above command is right and will work.
how to run cron under a normal user,mean to create a file like cron.allow OR cron.deny

Any details will be appreciated.

Thanks

The cron file is the crontab. You edit the file with the command:

crontab -e

It'll put you in your default editor. The command you gave:

10 * * * * /usr/local/bin/php /var/www/html/cron.php

is wrong. It'll run at 10 minutes after the top of each hour (ex 2:10, 3:10, 4:10, etc). What you want is:

0-59/10 * * * * /usr/local/bin/php /var/www/html/cron.php

This says to run at minute 0 and step in 10 minute intervals. Look at the manpage for crontab for details:

man 5 crontab

You shouldn't have to do anything with cron.allow or cron.deny. I believe the default is to allow all users to set up crontabs.

Thanks vsemaska.
I was aware of that to setup mins.
Also i think we can put like */10.It will run after 10 min every hour.
i will try your solution as you mention.
I tried it also from some sources of google.but i think the problem was coming from PHP execution directory.
I am going to try on other linux distro.
Hope it will work.

Thanks buddy for your time.
