env_path=/bin:/usr/bin
;Umask to set, specify in octal notation
umask=0077
; Minimum UID
min_uid=100
; Minimum GID
min_gid=100

 DocumentRoot /var/www/html/example.com
 ServerName example.com
 ServerAlias www.example.com
 ServerAdmin webmaster@example.com

 <FilesMatch ".+\.ph(p[345]?|t|tml)$">
 SetHandler None
 </FilesMatch>

 <IfModule mod_suphp.c>
 suPHP_Engine on
 <FilesMatch "\.php[345]?$">
 SetHandler x-httpd-suphp
 </FilesMatch>
 suPHP_AddHandler x-httpd-suphp
 </IfModule>
</VirtualHost>

-- Save & Quit (:wq)

# service httpd restart

Step: 12. Test the SuPHP Setup :

http://example.com/info.php

Note: Important is the ServerAPI line which shows CGI/FastCGI. which shows that PHP is run through SuPHP & not mod_php.

# vi /var/www/html/example.com/testuser.php

<?php
echo get_current_user();
?>

-- Save & Quit (:wq)

# chown -Rf web1:web1 /var/www/html/example.com/testuser.php
