如何在Amazon EC2 ubuntu服务器上激活延迟的作业？

Question

On Heroku, I just install an addon and it's all. On localhost, I have installed a deamon gem, delayed jobs gems and that was done. I ran an action as

Notifier.delay.signup(@user)

and the record was added to delayed_jobs table. Then I ran rake:jobs:work and all records in delayed_jobs table were processed.

But on EC2, the records are added to database, but there are not processed -- how to automatically process them?

EDIT: I've installed these gems:

gem 'delayed_job_active_record'
gem "daemons", "~> 1.1.9"

Answer 1

See https://github.com/collectiveidea/delayed_job#running-jobs

RAILS_ENV=production script/delayed_job start

Or 'bin/delayed_job' in rails 4

This will fire up 1 delayed job process, note that you can and may want to run this on another EC2 box if running rails and delayed job on the same box is too resource intensive
