ruby-on-rails - redis 尝试连接到 Heroku 中的本地主机 - 为什么？

Question

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 - 连接到 127.0.0.1:6379 上的 Redis 时出错(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 我得到这个:

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。

编辑

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。

Answer 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。我做了一个配置引用:

heroku config:set REDIS_PROVIDER=REDISTOGO_URL

问题就解决了

我在我的blog post中给出了详细的解释。
