Redis / Resque [在本地主機上連接到Redis時出錯：6379（ECONNREFUSED）]

Question

我正在嘗試使用Resque將Rails應用程序連接到Redis-to-go服務器，但出現錯誤：

Error connecting to Redis on localhost:6379 (ECONNREFUSED)

我嘗試了很多可能的解決方案，但是其中任何一個都有效。 我在這里遵循所有指示，但什么也沒有。

我有2個初始化器：

redis.rb

ENV["REDISTOGO_URL"] ||= "redis://redistogo:7d3dd2a11d0018445472de9d676360c3@albacore.redistogo.com:9408/"
uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)

resque.rb

Resque.redis = REDIS
Dir["#{Rails.root}/app/workers/*.rb"].each { |file| require file }


Resque.before_fork do
  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.connection.disconnect!
end

Resque.after_fork do
  defined?(ActiveRecord::Base) and
    ActiveRecord::Base.establish_connection
end

和rake文件：

require 'rake/dsl_definition'
require 'resque/tasks'


task "resque:setup" => :environment do
  ENV['QUEUE'] ||= '*'
    Resque.before_fork do
        defined?(ActiveRecord::Base) and
         ActiveRecord::Base.connection.disconnect!
    end

    Resque.after_fork do
      defined?(ActiveRecord::Base) and
        ActiveRecord::Base.establish_connection
    end
end

namespace :resque do
  desc "let resque workers always load the rails environment"
  task :setup => :environment do
    ENV['QUEUE'] ||= '*'
    Resque.before_fork = Proc.new { ActiveRecord::Base.establish_connection }
  end

  desc "kill all workers (using -QUIT), god will take care of them"
  task :stop_workers => :environment do
    pids = Array.new

    Resque.workers.each do |worker|
      pids << worker.to_s.split(/:/).second
    end

    if pids.size > 0
      system("kill -QUIT #{pids.join(' ')}")
    end

    # god should handle the restart
  end
end

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

我添加了很多部分的代碼，所以現在有點丑陋，但是在我嘗試使用redis-to-go之前，我在本地將其與其他配置一起使用，並且可以正常工作，但是現在我想在heroku中進行部署並且存在問題開始：c。

PS

如果我嘗試手動插入/獲取Redis，它會起作用！ （導軌控制台）

irb(main):001:0> REDIS.set("foo", "bar")
=> "OK"
irb(main):002:0> REDIS.get("foo")
=> "bar"

嘗試使用Redis.new（url：REDIS_URL）語法而不是URI.parse

if Rails.env == 'production'
  $redis = Redis.new(url: ENV["REDISCLOUD_URL"])
else
  $redis = Redis.new
end
