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

require "delayed/recipes"  

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

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

Hook into Capistrano to start, stop and restart

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