This modules wraps php-resque to be able to make scheduled background jobs in sweet harmony with redis.


  • SilverStripe with requirements
  • Redis server
  • (optional) a worker monitor, eg god or monit, to start and monitor the worker(s).
  • This module requires that the PHP pcntl module is installed

Still in development

The principle is that a 'front-end' adds a job via Resque class, this is a very fast operation.

$args = array(
    'message' => 'from '.$_SERVER['HTTP_HOST'],
    'time' => date('Y-m-d H:i:s')
$token = Resque::enqueue("dev:ping", "SSResquePingJob", $args);

This will be sent over tcp to a redis server that will hold this information until a worker fetches it.

By starting one or many worker via the cli, they will pull jobs from a 'queue' on redis, ie: dev:ping. Then it will find a PHP class to run the job, SSResquePingJob populate it with the $args and then run SSResquePingJob->perform().

public function perform() {
    echo 'Ping: '.$this->args['time'].' '.$this->args['message'].PHP_EOL;

Any exception or errors will mark the job as failed, and it's possible to requeue it.


Install redis

Via homebrew:

$ brew install redis

Or by compiling it, see Redis Quick Start for more information.

$ sudo mkdir -p /usr/local/src
$ cd /usr/local/src
$ sudo wget
$ sudo tar xvzf redis-stable.tar.gz
$ cd redis-stable
$ sudo make
$ sudo make install

There are most likely a suitable packages in your prefered linux distribution (untested).

Silverstripe Resque

$ git clone resque
$ cd resque
$ composer update


Start the redis server:

$ redis-server

Start the one worker for all queues in another terminal window

$ ./framework/sake dev/resque/run queue=*

In another terminal window, try creating a ping job

$ ./framework/sake dev/resque/ping

In the worker terminal you should now see something similar to

Ping: 2012-11-15 10:51:29 from hostname

Web interface

sudo gem install resque --no-ri -no-rdoc

Process monitor

How to install god on ubuntu / debian: How to monitor Resque with God and do it all with Capistrano on Ubuntu

Example configuration:

num_workers = 2

num_workers.times do |num| do |w| w.dir = "/var/www/site" = "site-worker-#{num}" = 'site-worker' w.interval = 30.seconds w.uid = 'www-data' w.gid = 'www-data' w.start = "/usr/bin/php ./framework/cli-script.php dev/resque/run queue=ping"

  # restart if memory gets too high
  w.transition(:up, :restart) do |on|
    on.condition(:memory_usage) do |c|
      c.above = 64.megabytes
      c.times = 2

  # determine the state on startup
  w.transition(:init, { true => :up, false => :start }) do |on|
    on.condition(:process_running) do |c|
      c.running = true

  # determine when process has finished starting
  w.transition([:start, :restart], :up) do |on|
    on.condition(:process_running) do |c|
      c.running = true
      c.interval = 5.seconds

    # failsafe
    on.condition(:tries) do |c|
      c.times = 5
      c.transition = :start
      c.interval = 5.seconds

  # start if process is not running
  w.transition(:up, :start) do |on|
    on.condition(:process_running) do |c|
      c.running = false



Here are the giants which shoulders I'm standing standing on:

  • Chris Boulton for PHP resque
  • defunkt the original resque for ruby
  • redis for providing an awesome, stable and fast key value store
  • SilverStripe The place where I get paid to do stuff like this.
