Delayed Job in Rails 4 with Capistrano

Question

I cant figure how to start Delayed Jobs on a dedicated Ubuntu server.

It works fine on my localhost but when I run on my server

sudo RAILS_ENV=production bin/delayed_job restart

I get

sudo: bin/delayed_job: command not found

On top of that, if I run the "rake jobs:work RAILS_ENV=production" command Im getting the following error:

 PG::FeatureNotSupported: ERROR:  SELECT FOR UPDATE/SHARE is not allowed in subqueries

Apparently theres an issue with my psql version.

Is there any way I can get the script to work? Any effective Capistrano recipes available? All ive found on the web are old recipes for Rails 3 and older versions of capistrano.

Thanks in advance.

EDIT:

I have already bundled install the daemons gem and generated "delayed_job:active_record" on my local machine, then proceded to cap deploy which bundle installed and migrated in the production server.

The bin/delayed_job file exists in the server yet it fails with command not found.

Are you sure you installed the gems at your server? bundle install ? — Eki Eqbal
Plz make sure to add gem "daemons" to your Gemfile, then bundle install. You have to run rails generate delayed_job:active_record && rake db:migrate. — Eki Eqbal
@EkiEqbal Yes I have already bundled install the daemons gem and generated "delayed_job:active_record" on my local machine. Do I have to run it on the production server also? — user3455909
Ya please run it at your production server, or if you want create a Capistrano recipe to automate that at the production server. — Eki Eqbal
Keep me updated so I can post it as an answer if your problem has been solved. — Eki Eqbal

And add this to config/environment.rb:

ENV['RAILS_ENV'] ||= 'production'

Then at your production server:

RAILS_ENV=production rake db:migrate 

RAILS_ENV=test production generate delayed_job:active_record && RAILS_ENV=production rake db:migrate

Now after you do that:

RAILS_ENV=production script/delayed_job start

As for Capistrano error you are facing, please try to add the command like:

run "cd #{current_path}; #{sudo} RACK_ENV=production bundle exec #{current_path}/bin/delayed_job start"
