使用Heroku在RedisToGo上使用Resque，Resque Server

I've been trying to get Resque (with Resque server) & RedisToGo working on heroku (cedar) for awhile now, but I keep running into this error:

我一直试图让Resque(使用Resque服务器)和RedisToGo在heroku(雪松)上工作一段时间,但我一直遇到这个错误:

Redis::CannotConnectError (Error connecting to Redis on 127.0.0.1:6379 (ECONNREFUSED)):

Its working locally, and I can access redis just fine in Heroku's console for my app.

它在本地工作,我可以在我的应用程序的Heroku控制台中访问redis。

My Procfile has:

我的Procfile有:

web: bundle exec thin start -p $PORT -e $RACK_ENV
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
resque: env TERM_CHILD=1 RESQUE_TERM_TIMEOUT=10 bundle exec rake resque:work

My Gemfile has:

我的Gemfile有:

gem 'redis'

#Background queue
gem 'resque', '~> 1.22.0', :require => "resque/server"

lib/tasks/resque.rake:

require 'resque/tasks'

task "resque:setup" => :environment do
  ENV['QUEUE'] = '*'
end

desc "Alias for resque:work (To run workers on Heroku)"
task "jobs:work" => "resque:work"

routes.rb:

  mount Resque::Server.new, :at => "/resque"

initializers: redis.rb:

uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)
Resque.redis = REDIS

resque.rb:

Dir["#{Rails.root}/app/workers/*.rb"].each { |file| require file }
Resque.after_fork = Proc.new { ActiveRecord::Base.establish_connection }

then in my app/workers directory I have something like myjob.rb

然后在我的app / workers目录中,我有类似myjob.rb的东西

I feel like I'm going in circles here, any ideas?

我觉得我在这里转圈,有什么想法吗?

I think your Procfile has a typo. Why do you have two web processes? I'd stick with one and use unicorn.

我认为您的Procfile有拼写错误。为什么你有两个网络流程?我坚持使用一个并使用独角兽。

web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

web:bundle exec unicorn -p $ PORT -c ./config/unicorn.rb

When using unicorn with resque, you have to define the resque redis connection each time unicorn forks. Here are the relevant files.

当使用具有resque的独角兽时,您必须在每次独角兽分叉时定义resque redis连接。这是相关文件。

config/initializers/redis.rb

uri = URI.parse(ENV["REDIS_WORKER"])
REDIS_WORKER = Redis.new(host: uri.host, port: uri.port, password: uri.password)

config/initializers/resque.rb

Resque.redis = REDIS_WORKER

config/unicorn.rb

before_fork do |server, worker|
  if defined?(Resque)
    Resque.redis.quit
    Rails.logger.info("Disconnected from Redis")
  end
end

after_fork do |server, worker|
  if defined?(Resque)
    Resque.redis = REDIS_WORKER
    Rails.logger.info("Connected to Redis")
  end
end
