Rails 3 and Capistrano

delayed_job comes with Capistrano recipes to start the script/delayed_job worker but you have to update your config/deploy.rb file to use them. There are 3 changes that need to be made:

Include the recipes

```ruby
require "delayed/recipes"  
```

The recipes use the :rails_env variable to pass the environment to script/delayed_job.

```ruby
 set :rails_env, "production" #added for delayed job  
```

Hook into Capistrano to start, stop and restart

```ruby 
# Delayed Job  
after "deploy:stop",    "delayed_job:stop"  
after "deploy:start",   "delayed_job:start"  
after "deploy:restart", "delayed_job:restart"  
```
