Question

我一直在使用sidekiq / redis很长一段时间没有问题。

出于某种原因，今天我收到了这个错误：

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

因此，Redis正在尝试连接到我的localhost连接而不是heroku中的redis_to_go url。

我的redis.rb文件如下所示：

uri = URI.parse(ENV["REDISTOGO_URL"] || "redis://localhost:6379/")
REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)

当我输入heroku config时，我得到了这个：

REDISTOGO_URL: redis://redistogo:b9f872ce1dd16cd989@albacore.redistogo.com:10280/

完全映射到我在Heroku的Redis To Go插件中看到的网址。

我知道昨天工作时和今天工作时没有任何改变，但我确实使用Mongo HQ启动了一个Mongo数据库。也许某处有冲突？

感谢任何帮助。

修改

我没有mongo init文件，我创建的唯一mongo特定文件是我的config/mongoid.yml文件。它看起来像这样：

development:
   sessions:
     default:
       database: mongoid_dev
       hosts:
        - localhost:27017
   options: #strictly 2 spaces before
     raise_not_found_error: false #strictly 4 spaces before not 6

 production:
   sessions:
     default:
       uri: <%= ENV['MONGOHQ_URL'] %>
   options: #strictly 2 spaces before
     raise_not_found_error: false #strictly 4 spaces before not 6

我从Master安装了Mongo并运行了rails 4.1.0。

Answer 1

我遇到了同样的问题。 Sidekiq 3+不会自动识别REDISTOGO_URL环境变量，而是使用REDIS_PROVIDER。我通过以下方式进行了配置参考：

heroku config:set REDIS_PROVIDER=REDISTOGO_URL

然后问题解决了

我在blog post

中提供详细说明

Answer 2

设置你的redis.rb文件：

 module MyApp
   class << self
     def redis
       @redis ||= Redis.new(url: (ENV['REDISTOGO_URL'] || 'redis://127.0.0.1:6379'))
     end
   end
 end

在您的sidekiq.rb中

执行：

 Sidekiq.configure_server do |config|

   Rails.logger = Sidekiq::Logging.logger

   config.redis = { :url => MyApp.redis[:url], :namespace => 'sidekiq', :size => 5 }
 end

 Sidekiq.configure_client do |config|
   config.redis = { :url => MyApp.redis[:url], :namespace => 'sidekiq', :size => 1 }
 end

这将确保Sidekiq从redis.rb init文件中获取Redis连接。

Answer 3

问题在于ENV变量：

Per sidekiq的文档：

RedisToGo可以与默认的REDISTOGO_URL env var一起使用 Sidekiq 2.x及更早版本（REDISTOGO_URL支持遗留原因，建议使用REDIS_PROVIDER和REDIS_URL变量。

对于sidekiq 3及以上，您必须使用REDIS_PROVIDER或REDIS_URL ENV varibles而不是REDISTOGO_URL。你不需要sidekiq初始化器，这段代码可以解决这个问题：

从终端

运行以下命令

heroku config:set REDIS_PROVIDER=redis://...........

redis试图连接到Heroku的本地主机 - 为什么？
