PHP Question

using cron to make php-script starting continuous processes

I created a cronjob which call a php-script every 5mins.

This PHP script needs to start several other PHP CLI scripts and keep them running in background even when the cron-script terminates.

I'm currently creating these sub-processes by the following line of code:

if (!$pid = shell_exec("nohup /var/[..]/cake.php test doSomething > /dev/null 2>&1 & echo $!")) return false;

When I call the "motherscript" via command-line everything's working great. But it seems like the sub-processes startet by the above line of code are terminated when the cron-job stops.

So how to spawn these
cake.php test doSomething
script and keep the child-process running under the predefined user in crontab?

That makes sense, you need to tell the children PHP scripts to NOT terminate when it's parent stops.


Add the above line to the children PHP scripts. Should do it
