I am trying to shutdown my RaspberryPi running Raspbian from a php script running on lighttpd webserver. shell_exec("sudo /sbin/shutdown -h now 2>&1");

I added lighttpd ALL=(ALL) NOPASSWD: /sbin/shutdown to my /etc/sudoers file and checked that Defaults !requiretty is set.

I still get "sudo: no tty present and no askpass program specified" when running the script.

Can somebody please help me? Thanks!

Lighttpd might not be running as user lighttpd.

In a PHP script, write the following to find out what https://forum.tuteehub.com/tag/user">user it runs with:

echo shell_exec('whoami');

It might be www-data or http instead.
