Executing PHP shell command requires sudo access

I have written PHP code to execute shell command

<?php exec("phing"); ?>

This is not working at all from browser.

But what I analysed is, it running same command requires "sudo" permission. I am not sure how could I allow my PHP file to execute this commnand as sudo?

Please guide

Solution

  • When executing php, you might not (probably won't be) in any particular directory. Try specifying the absolute path <?php exec("/usr/bin/phing"); ?> Also, did you mean ping instead of phing?

    If the webserver has sudo access (a REALLY BAD IDEA) without a password (a REALLY BAD IDEA!!!) to run this command, then you need to change your code to <?php exec("/usr/bin/sudo phing"); ?>

    To be able to run sudo, you will need help from the administrator of your computer. I doubt your administrator will allow this, because it's risky to give the webserver sudo access - a lot of work goes into making sure the web server does NOT have any sort of administrator privileges.
