我在 Windows 10上的rails应用程序中连接到redis时遇到问题,我将redis添加到我的gem文件并设置了我的cable.yml文件.当我启动我的rails服务器时我得到的错误是在establish_connection中进行救援’：超时连接到localhost上的Redis：6379如何解决此问题.

cable.yml

development:
  adapter: redis
  url: redis://localhost:6379/1

test:
  adapter: async

production:
  adapter: redis
  url: redis://localhost:6379/1

解决方法

好吧,我遇到了同样的问题,这对我来说是有用的.linelymlconfig：

development:
  adapter: async

疯狂的是,它实际上连接到我的本地redis服务器！我想它不应该在配置中使用redis,但它正在使用它并且它工作得很好.

相反,如果我设置我认为正确的配置,它会失败：

development:
  :adapter: redis
  :url: redis://localhost:6379/

这是错误：

C:/RailsInstaller/Ruby2.3.0/lib/ruby/gems/2.3.0/gems/redis-3.3.3/lib/redis/client.rb:345:in `rescue in establish_connection’: Error connecting to Redis on localhost:6379 (Redis::TimeoutError) (Redis::CannotConnectError)

所以,我不知道为什么,如果有人可以解释它会很棒,但是使用适配器：async它为我解决了(Rails 5.0.7,Windows 10,redis gem 3.3.3).
