su to root
ps auxwww | grep socketxxx.php
If 'xxx' changes, you could just maybe do:
ps auxwwww | grep socket | grep php
Once you're sure you know what you want to kill, you could use 'kill'
to kill it.
You'll need the process ID number, which is the first number you see
in the row, right after the username.
Now that I've answered your question...
Almost for sure, whatever it is you THINK you should be doing, you've
done something else horribly wrong that is making you THINK you should
be searching for and killing these processes, but you shouldn't. :-)
Since they already ARE php, it would probably be MUCH simpler to alter
the PHP in your socketxxx.php script, and add a couple lines like
this:
<?php
$start = date('Y-m-d');
//more code here
while (1){
if (date('Y-m-d') != $start) exit;
//socket reading/handling code here
}
?>
This presumes you actually need the process to die in the first place,
which sounds kinda hinky in and of itself, to tell you the truth...
Most Un*x socket-based processes start at boot and run forever until
the machine is shutdown, or somebody trips over the power-cord.
