Trying to learn how to implement a cron job using php.
cron is formatted like so
* 13 * * * /usr/bin/php /var/www/path/to/file/database-bkup-test.php &>/tmp/mycroncommand.log
So this should run at 13 hour daily (1 pm)
I reviewed the status of the service with
sudo systemctl status crond.service -l
Found the following error:
(/usr/bin/php) ERROR (getpwnam() failed)
I have this set up using PHP, the script is basically this:
$today = date('Y-m-d'); $user = 'db_user'; $password = 'db_password'; $host = '127.0.0.1'; //this is actually replaced with an address to another remote server $port='3306'; $database='database_name'; exec('mysqldump --user='.$user.' --password='.$password.' --host='.$host.' --port='.$port.' '.$database.' > /db-bkup/db-'.$today.'.sql');
the end result would be a database dump into a file:
Could anyone please assist me?
I have spent time reading and trying to implement this. I found this post to be very helpful
Since the job is failing, the whole thing is not even generating the log in the
Added a simple cron to echo 'Hello World';
*/2 * * * * root /scripts/test.php &>/tmp/mycrontest.log
This time I have a log generated with Permission Denied. I presume that is because I never applied /usr/bin/php
This is a step forwards from original error.
