PHP exec to restart mysqld

I want to do something very very bad. I want to create a button that restarts mysqld. Why is irrelevant for my issue.

Here is my php script ...
       	exec("sudo /etc/init.d/mysqld restart");        
<form method="POST">
<input type="submit" name="restart" value="restart">

On any old server this usually can work. But on my locked down amazon ec2 server it doesn't. I tried putting this in the sudoers file but the button still doesn't restart mysqld.

Cmnd_Alias RESTART_APACHE = /etc/init.d/httpd restart

Cmnd_Alias RESTART_MYSQL = /etc/init.d/mysqld restart

I'm stumped, at wits end, maybe someone here knows the solution ?

Check the apache error log for messages.
Is it working on the command line?

I don't really see anything in the log file...
It does work on command line.

check auth log for error. are you sure it'd exec as apache user (maybe 'nobody')?
