Question

I’m following the configuration guidelines for installing resque. I’m met with a (OpenURI::HTTPError). I’m using RVM 1.9.2-p180, rails 3.0.6, and POW.’resque-web’ fails to start with a 500 Server Error. What the heck is going on here?

To replicate problem:

1. Start redis with $ redis-server
2. Start a worker with $ VVERBOSE=1 QUEUE=file_serve rake environment resque:work
3. Try to start Resque-Web with: RAILS_ENV=development resque-web config/initializers/resque.rb

config/resque.yml

development: localhost:6379
test: localhost:6379
staging: localhost:6379
fi: localhost:6379

initializers/resque.rb:

rails_root = ENV['RAILS_ROOT'] || File.dirname(__FILE__) + '/../..'
rails_env = ENV['RAILS_ENV'] || 'development'

require 'resque'
# require 'yaml'

unless defined?($redis)
  $redis = Redis.new($redis = Redis.new(:host => 'localhost', :port => 6379))
end

Resque.redis = $redis

Terminal:

     master ~/projects/MyApp $ RAILS_ENV=development resque-web config/initializers/resque.rb

Initializers/redis.rb

$redis = Redis.new(:host => 'localhost', :port => 6379)

Terminal: (proof of $redis)

> $redis

Answer 1

You have:

$redis = Redis.new($redis = Redis.new(:host => 'localhost', :port => 6379))

Try just doing:

$redis = Redis.new(:host => 'localhost', :port => 6379)
