ubuntu

Hi,

I am using Ubuntu Dapper and I want to run a command as root from a php script.

I try:

<?php
$output = shell_exec('sudo -u root -S ls < /home/mitilma/passfile');
echo "<pre>".$output."</pre>";
?>

However, ls command does not work in that case. It works without sudo in php, but with sudo, I cannot see any files listed. What is the problem? How can I solve it?

Thanks a lot..

Have you setup sudo for the Apache user and to not require a password from that user for that command?

You said
"Have you setup sudo for the Apache user and to not require a password from that user for that command?"

How can I achieve it? I am new for Linux, and I really need help..

Thanks a lot..

As root, run 'visudo' and add something similar to these lines:

Code:

Cmnd_Alias      APACHECMDS =    /path/to/command/for/apache/user/to/run

apacheusername   ALL = APACHECMDS   NOPASSWD

If you need to allow it to run multiple commands, add a backslash to the Cmnd_Alias line like this:

Code:

Cmnd_Alias      APACHECMDS =    /path/to/command/for/apache/user/to/run \
                                  /path/to/second/command/for/apache/to/run

You can keep adding back slashes and more commands for as long as you like
