redis 尝试连接到 Heroku 中的本地主机 - 为啥？

【中文标题】redis 尝试连接到 Heroku 中的本地主机 - 为啥？【英文标题】：redis attempting to connect to local host in Heroku - WHY?redis 尝试连接到 Heroku 中的本地主机 - 为什么？ 【发布时间】：2014-05-30 03:36:51 【问题描述】：

我使用 sidekiq/redis 已经有一段时间了，到目前为止没有任何问题。

由于某种原因，今天我收到此错误：

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

所以，Redis 正在尝试连接到我的 localhost 连接，而不是我在 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/

它完全映射到我在 Heroku 的 Redis To Go 插件中看到的网址。

据我所知，从昨天的 Redis 工作到今天的不工作，Redis 没有发生任何变化，但我确实使用 Mongo HQ 启动了一个 Mongo DB。也许某处有冲突？

感谢任何帮助。

我没有 mongo 初始化文件，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，并且正在运行 rails 4.1.0。

【问题讨论】：

你能试着用Redis.new(url: (ENV['REDISTOGO_URL'] || 'redis://127.0.0.1:6379')) 来简化你的初始化程序吗？这就是我文件中的全部内容。 @blootto 没有骰子。我什至取出了or localhost 部分，但它仍然不起作用。它必须从其他地方获取本地主机 URL。我的猜测是您项目中的其他代码没有抓取 inits Redis 对象。转到 heroku 控制台并进行一些快速测试.. 1) p ENV['REDISTOGO_URL'] 2) Redis.new(url: (ENV['REDISTOGO_URL'])) ;如果这确实指向 albacore 而不是 localhost，则您的项目代码根本不会访问您的初始化对象。接下来我会在提议的答案中推荐一些配置他们确实都指向长鳍金枪鱼 - 我猜是时候回溯并找出问题所在了。 【参考方案1】：

我遇到了同样的问题。 Sidekiq 3+ 不会自动重新识别 REDISTOGO_URL 环境变量，而是使用 REDIS_PROVIDER。我做了一个配置参考：

heroku config:set REDIS_PROVIDER=REDISTOGO_URL

问题就解决了

我在blog post中给出详细解释

【讨论】：

这是最好的答案 @DipakPanchal，我很高兴它有帮助！【参考方案2】：

这样设置你的 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

在你的 sidekiq.rb 中做：

 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 从您的 redis.rb 初始化文件中获取 Redis 连接。

【讨论】：

bahh 完全没有运气地复制了它。我将我的应用程序回滚到设置 MongoHQ 之前，它工作正常。我必须在 Mongo 的设置中做一些事情来搞砸。是的..我想知道 Mongo 是否覆盖了你的一些 Redis 配置。也许也可以为 Mongo 发布您的初始化。【参考方案3】：

问题在于 ENV 变量：

根据 sidekiq 的文档：

RedisToGo 可以与默认的 REDISTOGO_URL 环境变量一起使用 Sidekiq 2.x 及更早版本（旧版支持 REDISTOGO_URL 原因，推荐使用 REDIS_PROVIDER 和 REDIS_URL 变量）。

对于 sidekiq 3 及更高版本，您必须使用 REDIS_PROVIDER 或 REDIS_URL ENV 变量而不是 REDISTOGO_URL。您不需要 sidekiq 初始化程序，这段代码可以解决问题：

从终端运行以下命令

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

【讨论】：

REDIS_PROVIDER 并不是用来保存实际的 URL - 它是用来保存包含 URL 的 ENV var 的名称。所以字面上应该是REDIS_PROVIDER=REDISTOGO_URL。
