Run sh file from php with cron

Question

I have an sh file with file-removing commands.

I run it from php like this:

shell_exec("sudo -n ./truncatefiles.sh  2>&1");

Thats works fine if I open the PHP file from browser, but doesnt work from scheduled cron tab.

PHP user: www-data

If i run whoiami from cron, returns same: www-data

I added this to my visudo:

www-data ALL=(ALL) NOPASSWD: /www/sites/..../importscript/truncatefiles.sh

Shell exec for this sh file returns (from cron):

sudo: sorry, a password is required to run sudo

Why works it dirrefent way in cron?

What should I do for get it work?

it's an apache webserver, right? – mirko911 Nov 29 '16 at 08:44 — mirko911, Nov 29 '16 at 08:44

PLease try to do the following, Try to log your output from crotab to a file, * * myscript.php >> /var/log/myjob.log 2>&1 This way you can debug your script. 1. Also the check the user and permissions for your shell script, php file. 2. try with sudo crotab -e

I know the response: sudo: sorry, a password is required to run sudo – bbenhu Nov 29 '16 at 09:31
PHP file 777, sh file 777 – bbenhu Nov 29 '16 at 09:31
shell exec this way: ./truncatefiles.sh 2>&1 ask password, beginning with sudo -n returns password is required. No more response :( – bbenhu Nov 29 '16 at 09:32
I would avoid having internet accessible PHP scripts having 777 permissions, it is a security problem. – jeremiah Nov 30 '16 at 14:06
Have you tried adding your shell script directly into your crontab and running it that way? – jeremiah Nov 30 '16 at 14:08
