How to check the server is Suexec

Login into you server with the root login details and run following command

[root@server]# /usr/local/cpanel/bin/rebuild_phpconf --current

If server is Suexec then result would look like

DEFAULT PHP: 5
PHP4 SAPI: suphp
PHP5 SAPI: suphp
SUEXEC: enabled

If you are not sure about Shell then you can also check the SuExec is enabled or not? from your WHM.Lgin into your WHM and in the menu find Configure PHP and SuExec

Check the drop down box for "PHP 4/5 Handler" - and if beside that it says "suPHP" - Then your sever is SuExec enabled

If you are not having server root login details or WHM access.Then you can create a php file udner your account from cPanel >> File Manager and change the permissions on that file to 777 and open it in a browser. If it gives 500 Internal Server Error, your most probably running suPHP.


As well as you can also create the phpinfo page under your account from your cPanel >> File manager For ex. phpinfo.php with the following code



After creating phpinfo.php page browse it http://yourdomainname.com/phpinfo.php and if it shows

Server API = Apache then server is not running PHP in Suexec mode

And if

Server API = CGI the server is running PHP in Suexec mode
