How to make a minutely cronjob on debian?

Can someone help me?

The "action" should be "php /var/www/cronjob/index.php"

i have no idea!

  • Cron works well down to one minute resolutions, but it fuzzes a bit around that mark. If it's important that it runs at the top of the minute very precisely, you may need to daemonize the PHP app in question.

*/N * * * * /path_to_php/php /var/www/cronjob/index.php

N - number of minutes. and you may need to specify full path to php (/usr/local/bin/php or whatewer)

    In my experience you always need to specify the full path, especially if you're running as a user such as www-data. The path to PHP is /usr/bin/php by default on Debian.

  • To make dealing with cronjob configuration easier, create a command on the shell which executes your PHP. This allows to change the details over time w/o changing the crontab, like a changed path to PHP or if you'd like to modify the php configuration of that task in specific. It will make the crontab easier to read as well.

1: * = every minute

2: * = every hour

3: * = every day of month

4: * = every month

5: * = every day of week
