PORun a php script in background on debian (Apache)
text
Body
copied!<p>I'm trying to make a push notification work on my debian vps (apace2, mysql). </p> <p>I use a php script from this tutorial (http://www.raywenderlich.com/3525/apple-push-notification-services-tutorial-part-2).</p> <p>Basically, the script is put in an infintive loop, that check a mysql table for new records every couple of seconds. The tutorial says it should be run as a background process. </p> <pre><code>// This script should be run as a background process on the server. It checks // every few seconds for new messages in the database table push_queue and // sends them to the Apple Push Notification Service. // // Usage: php push.php development & </code></pre> <p>So I have four questions. </p> <ol> <li><p>How do I start the script from the terminal? What should I type? The script location on the server is:</p> <p>/var/www/development_folder/scripts/push2/push.php </p></li> <li><p>How can I kill it if I need to (without having to restart apace)?</p></li> <li><p>Since the push notification is essential, I need a way to check if the script is running. The code (from the tutorial) calls a function is something goes wrong: </p> <pre><code>function fatalError($message) { writeToLog('Exiting with fatal error: ' . $message); exit; } </code></pre></li> </ol> <p>Maybe I can put something in there to restart the script? But It would also be nice to have a cron job or something that check every 5 minute or so if the script is running, and start it if it doens't. </p> <p>4 - Can I make the script automatically start after a apace or mysql restart? If the server crash or something else happens that need a apace restart? </p> <p>Thanks a lot in advance</p>
