After opening and reading every result on Google, I figured it's time to make my own thread somewhere. I am sorry that I need to ask a question that's already been asked before, I cannot stress this enough, but I have no other option as no other question asked has helped me achieve what my goal is.
I'm trying to setup a means of rebooting/doing other system functions through a web interface powered by HTML (for the buttons/text) and PHP (for the execution of the aforementioned functions).
I'm unable to get this to work. I've read that I need to add the web user to the sudoers file, and I've tried. I'm running Nginx on my server, how do I add the user to the sudoers in my case?
Also, I'm aware of the security risks.
The following is what I have so far:
HTML (index.html):
<body>
<h3>Restart</h3>
<p>
<form action="restart.php" method="get">
<input type="submit" value="Press me.">
</form>
</p>
</body>
PHP (restart.php):
<?php
echo "This is a test";
echo "<br>";
echo "<br>";
echo shell_exec('ifconfig');
echo "<br>";
echo "<br>";
echo "Restarting server...";
exec ('/usr/bin/sudo /etc/init.d/portmap restart');
shell_exec("/sbin/reboot");
exec("/sbin/reboot");
system("/sbin/reboot");
?>
Mind you that here, I only have so many things attempting to execute, so that I make sure I hit the target when one of them works, if that makes sense. The IFConfig is just a test to make sure that it's actually able to execute.
Sudoers:
# User privilege specification
root ALL=(ALL:ALL) ALL
www-data reboot = NOPASSWD: /sbin/reboot
This is all on Ubuntu 14.04 LEMP.

To start the server, run the start-ds command on UNIX or Linux systems or the start-ds. bat command on Windows systems. By default, the start-ds command starts the server as a background process when no options are specified.
You can do this either by editing your sudoers file :
Sudoers:
www-data ALL=(root) NOPASSWD: /sbin/reboot
The first ALL is for the hostname if you're hostname is not 'reboot' I advise you to keep ALL as it will work in any hostname. That's why it doesn't seem to work on your server
restart.php
exec('sudo /sbin/reboot');
Or without editing your sudoers file.
~/password :
myrootpassword
phpfile.php :
exec('sudo -u root -S /sbin/reboot < ~/password');
