Question

I’m trying to make a open source kiosk like system. When the web browser starts all programs, it will run in the browser using PHP. I’ve found this link: Program execution Functions. It’s using:

<?php
  $WshShell = new COM("WScript.Shell");
  $oExec = $WshShell->Run("WINWORD.exe", 7, false);
?>

I was able to start Microsoft Word on Windows, but I need to be able to do this on Linux.
This is what I’ve tried on my Linux server:

<?php
  exec("/var/www/test.sh");
?>

But nothing happens. I know that test.sh works because I ran if from the terminal. I use test.sh to start a Python script. The Python script starts a text editor. I’ve tested the Python script and it works. All I need know is how to start the script from PHP on Linux.

Answer 1

I had to change the test.sh owner permission to www-data
then add

Cmnd_Alias  RUN = /var/www/test.sh
www-data      ALL = (root) NOPASSWD: RUN

To /etc/sudoers then the php code

<?php
shell_exec("sudo /var/www/test.sh");
?>
