Execute Python script from Php
You can't use sudo from a PHP script. Apache is running from an user (www-data generaly), so edit this file : /etc/sudoers
Then add this line :
www-data ALL=(ALL) NOPASSWD:ALL
Care ! this will authorize all functions to be called by a PHP script, you can adapt changing "ALL" by your script or Python command.
Then precise your user in your exec command :
<?phpexec('sudo -u www-data python /usr/lib/cgi-bin/script.py')
Try this out, it should be working:
<?php system("cd /usr/lib/cgi-bin");system("sudo python script.py");?>
Or even this:
<?php system("cd /usr/lib/cgi-bin && sudo python script.py");?>
On an older Raspbian distribution you need to place your file in /var/www/file.py
. So in your file.php you add:
{ exec("sudo python /var/www/file.py");}
On a newer Raspbian Jessie you need to place your file in /var/www/html/file.py
, so in your file.php you need to add:
{ exec("sudo python /var/www/html/file.py");}
Or just any file.py
<?php{ exec("sudo python test.py");}
?>
Note: For this to work you need to edit a file first to add these lines to allow passwordless sudo
sudo nano /etc/sudoers
then go to the bottom and add this
pi ALL=(ALL) NOPASSWD: ALL<br>www-data ALL=(ALL) NOPASSWD: ALL
