Run BASH script from .PHP file

Question

Bash file:

#!/bin/bash
mkdir /var/www/html/bash

PHP file:

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

After I enter localhost/phpfile.php /var/www/html/bash directory Is not created. I tried shell_exec command no results as well. What I'm doing wrong?

-rw-r--r-- 1 root root 40 Nov 7 18:47 phpfile.php -rwxrwxrwx 1 root root 39 Nov 7 18:46 bashfile.sh files are in root group so they should have it. Am I wrong? — demboz11

First find the user for Apache sudo ps aux |grep apache or sudo ps aux |grep httpd On my server I get www-data So, to allow it to create directories, I chmod the parent folder 775, then chgrp www-data /parentdir ps chmod and chgrp will also need to be done via sudo — Duane Lortie

@JayBlanchard can you tell me how to do it? Or maybe you could give me a link, where I can read more about it. — demboz11

It's likely failing because Apache does not have write permissions within your ./var/www/html directory. To give Apache the necessary permissions, try this...

First find the user for Apache sudo ps aux |grep apache or sudo ps aux |grep httpd

On my server I get www-data So, to allow it to create directories, I chmod the parent folder 775, sudo chmod 775 /var/www/html

Then, change the group owner to the user that runs apache (www-data in my case)

sudo chgrp www-data /var/www/html
