scenarios with cron job not executing PHP script on Debian 11: logs show 'Permission denied'
Could someone explain I'm confused about I've set up a cron job on my Debian 11 server to run a PHP script every hour, but it's failing to execute with a 'Permission denied' behavior in the logs..... The cron job is defined like this: ```bash 0 * * * * /usr/bin/php /var/www/html/myscript.php ``` I checked the ownership and permissions of the script, and it looks like this: ```bash ls -l /var/www/html/myscript.php ``` Output: ``` -rw-r--r-- 1 www-data www-data 2048 Oct 1 12:00 myscript.php ``` The script is owned by the `www-data` user, which is the same user that the web server runs as. I also confirmed that the PHP binary has the correct permissions: ```bash ls -l /usr/bin/php ``` Output: ``` -rwxr-xr-x 1 root root 123456 Jul 15 10:00 /usr/bin/php ``` I've tried running the script manually as the `www-data` user using `sudo -u www-data /usr/bin/php /var/www/html/myscript.php`, and it works just fine without any errors. However, when the cron job runs, the logs show: ``` /bin/sh: 1: /usr/bin/php: Permission denied ``` I've verified that there's no SELinux or AppArmor policy interfering with the execution, as both are either disabled or set to permissive mode. The cron service is running as expected, and I checked the cron logs with `grep CRON /var/log/syslog` to confirm that the job is indeed being triggered. Is there something I'm missing with the environment that cron runs in? Any ideas on how to troubleshoot or resolve this permission scenario? Has anyone else encountered this? This is for a application running on CentOS. Is there a simpler solution I'm overlooking? Any ideas what could be causing this? This is for a mobile app running on CentOS. Is there a simpler solution I'm overlooking?
