#CodeMemeDaemonBundle 
This will enable you to install the symfony bundle and easily convert your Symfony2 console scripts into system daemons.
pcntl is required to be configured in your PHP binary to use this. On my Ubuntu server I was able to install pcntl easily with the following command:
sudo apt-get install php-5.3-pcntl-zend-server
##System_Daemon PEAR package## System_Daemon is a PHP class that allows developers to create their own daemon applications on Linux systems. The class is focussed entirely on creating & spawning standalone daemons
More info at:
##DaemonBundle Config## Place CodeMeme\Daemonbundle in your src directory and do the following:
add the bundle to your deps configuration
[CodeMemeDaemonBundle]
git=http://github.com/CodeMeme/CodeMemeDaemonBundle.git
target=/bundles/CodeMeme/Bundle/CodeMemeDaemonBundle
Add the following to your autoload.php file:
$loader->registerNamespaces(array(
//...
'CodeMeme' => __DIR__.'/../vendor/bundles',
));
Add The CodeMemeDaemonBundle to your kernel bootstrap sequence
public function registerBundles()
{
$bundles = array(
//...
new CodeMeme\Bundle\CodeMemeDaemonBundle\CodeMemeDaemonBundle(),
);
//...
return $bundles;
}
By Default, system daemons have a sensible configuration. If you need to change any configuration setting , you could do it by adding this configuration to your project config. Only the values that need to be changed should be added, the bundle extension will merge your daemon configs into its defaults.

You can run the daemon as a different user or group depending on what is best for your application. By default it will resolve the user and group of the user who is running the daemon from the command console, but if you want to run as a different user you can use the appUser, appGroup or appRunAsGID, appRunAsUID options. Remember if you need to run as a different user you must start the daemon as sudo or a superuser.
To find out the group and user id of a specific user you can use the following commands.
jesse@picard:~/ninethousand.org$ id -u www-data
jesse@picard:~/ninethousand.org$ id -g www-data
##Creating a Daemon## The Following links are examples of how to use a system daemon in an example project
##Usage## Once you have Daemonized your symfony Console Commands, you can simply run them from the command line like so:
jesse@picard:~/codememe$ php app/console jobqueue:start
jesse@picard:~/codememe$ php app/console jobqueue:stop
jesse@picard:~/codememe$ php app/console jobqueue:restart
