#Uecode DaemonBundle #
DEPRECATED / NO LONGER SUPPORTING
Its now pretty easy to daemonize php commands using upstart, or init.d. Please use those instead of this, as you will get a lot more support.
##Overview## DaemonBundle is a wrapper for the PEAR library System_Daemon which was created by Kevin Vanzonneveld.
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##
THIS BUNDLE REQUIRES THE Uecode\Bundle\UecodeBundle (https://github.com/uecode/uecode-bundle)
Place Uecode\Bundle\Daemonbundle in your src directory and do the following:
composer.json
"uecode/daemon-bundle": "dev-master",
appKernel.php
Add The DaemonBundle to your kernel bootstrap sequence
public function registerBundles()
{
$bundles = array(
//...
new Uecode\Bundle\DaemonBundle\DaemonBundle(),
);
//...
return $bundles;
}
config.yml
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 MUST HAVE AT LEAST THIS PIECE TO WORK

##Creating a Daemon##
##Code## Make sure you extend \Uecode\Bundle\DaemonBundle\Command\ExtendCommand
<?php
namespace Uecode\Bundle\DaemonBundle\Command;
use \Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use \Symfony\Component\Console\Input\InputInterface;
use \Symfony\Component\Console\Input\ArrayInput;
use \Symfony\Component\Console\Output\OutputInterface;
use \Symfony\Component\DependencyInjection\Container;
use \Uecode\Bundle\DaemonBundle\System\Daemon\Exception;
use \Uecode\Bundle\DaemonBundle\Service\DaemonService;
/**
* Example Command class
*/
class ExampleCommand extends ExtendCommand
{
/**
* Configures the Command
*/
protected function configure()
{
$this
->setName( 'example' )
->setDescription( 'Starts an example Daemon' )
->setHelp( 'Usage: <info>php app/console example start|stop|restart</info>' )
->addArgument( 'method', InputArgument::REQUIRED, 'start|stop|restart' );
}
/**
* Sample Daemon Logic. Logs `Daemon is running!` every 5 seconds
* @param \Symfony\Component\Console\Input\InputInterface $input
* @param \Symfony\Component\Console\Output\OutputInterface $output
*/
protected function daemonLogic( InputInterface $input, OutputInterface $output )
{
// Do a little logging
$this->container->get( 'logger' )->info( 'Daemon is running!' );
// And then sleep for 5 seconds
$this->daemon->iterate( 5 );
}
}
##Usage## Once you have Daemonized your symfony Console Commands, you can simply run them from the command line like so:
aequasi@ue:~/example$ php app/console queue:start
aequasi@ue:~/example$ php app/console queue:stop
aequasi@ue:~/example$ php app/console queue:restart
