exec(); works on nginx but not on apache2
Hello,
I have to VPS running with debian 6.0.7 64 bit. On one runs apache2 with php5 and on the other nginx with php-fpm. I created an exec.php file which contains that:
<?php echo "successfully!"; exec("mkdir test"); ?>
On nginx it works perfectly right out of the box. But I can't make it run on apache2 webserver. I checked my php.ini (under /etc/php5/apache2/php.ini) and safe mode is off and exec isn't listed unter disable_functions.
Why doesn't exec work on apache2?:(
Thanks!

most likely they both use different php.ini's one most likely dissalows exec. You say you have checked, do a diff and compare.
e.g
/etc/php5/php5-fpm/php.ini
and
/etc/php5/apache2/php.ini
change the file/folder ownership and check chmod ?
any panel installed?
Pipe stderr to stdout and echo the results of the command.
This should assist you in identifying the issue.

My control panel uses three different php.ini
Maybe do a
find /etc -iname php\.ini -exec grep --color -in 'disable_function' {} \;turn on verbose error messages? http://www.php.net/manual/en/function.error-reporting.php
I checked both and I don't find an option which is different and affects exec
It tried it with root and www-data as owner, I also gave the php file 777 rights.
No
It always says: "mkdir: cannot create directory `test': Permission denied"
No matter who is the owner or if it has 777 rights.
As I don't use a panel, I think that won't help. But thanks!
I did this with the comman from Adduc, didn't I?
Thanks for your answers!
It may be an SELinux permissions issue, if you're running RHEL or a derivative.
What's the output of
sestatus?You mean just sestatus in putty?
Yes
root@nyc:~# sestatus
-bash: sestatus: command not found
I use debian 6.0.7 btw. Maybe this command isn't available with debian.
Why not nginx on both?
Sure, I could install nginx on the other too. But altough I would like to know what I did wrong
I'm new with linux and I think it's important to get it work 
I'm not into PHP so I don't know if
exec()uses the relative directory, but try creating the full path, eg. withexec("mkdir /var/www/test");or whatever.Doesn't change anything but thanks
Think it has something to do with apache2 running under www-data and executing it as www-data and nginx runs as root.
Since it's exec alone that's affected, did you check phpinfo() to see if exec is enabled?
Is
/var/www/itself owned bywww-dataor with 777 permission?Since you are modifying the parent directory.

This was it! I don't know why it works under nginx, but under apache2 you have to set the owner of /var/www/ as www-data (makes sense, the script has to have the right to create a folder. So I have set 777 and chown www-data:www-data to all files in /var/www/, but not to the folder www itself.
Thanks for all your answers!
