following php code is part of my script and owned by user "X"

(X is created by WHM)

exec ("./my_shell_script.sh> /dev/null &");

and my_shell_script.sh is a shell script and diven right permission to be executed;

contents of my shell script is


#!/bin/sh

while true
do
./my_program
sleep 1
done



I can run the php script on a redhat - works fine, "my_program" is listed in the current processos and its owned by the user "X"

so the same php script can terminate the program (" my_program") since its owned by the same user /owner

but when I run the same script in Fedora "my program" is not stable (I could see multiple instances and not stable) and its owned by user "nobody" - I am unable to reminate the program becasue the programm is runnng as nobody

note: shell is enabled on both redhat and fedora accounts

is it because i am using two different operating systems or I have configured the OS differently?

please help me

Are you sure suexec is not coming into play here?

suexec is enabled in both systems

This has nothing to do with Redhat/Fedora and everything to do with your Apache setup.

Apache by default, runs modules all under the same user (i.e. "nobody", "www", "www-data") If you happen to be using mod_php, then this is what's going to happen.

To have PHP scripts run under a particular user identification, you have a couple of courses of actions:

1. Use su-exec (it's quite possible, it's simply not setup correctly on your system)
2. Use the MPM module with Apache2 (This still doesn't work correctly as far as I know)
3. Use mod_suphp http://www.suphp.org/

Apache is configured differently on both machines. A list of LoadModule lines might give a clue, but realisitically, you're going to need to go through.

If you can get the output of httpd -L (or apache -L ... it depends what your apache binary is called) on both machines, a reasonably accurate comparison could be made. Although normally it's painstaking as both are typically quite large.

thanks for the reply phil...

its working fine after recompiling the apache with phpsuexec

thanks a lot :)
