我一直在使用sidekiq / redis一段时间没有问题.
由于某些原因,今天我得到这个错误：
Redis :: CannotConnectError – 连接到Redis on 127.0.0.1:6379(ECONNREFUSED)时出错：
所以,Redis试图连接到我的本地连接,而不是我的redis_to_go url在heroku.
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配置时,我给了这个：
REDISTOGO_URL: redis://redistogo:b9f872ce1dd16cd989@albacore.redistogo.com:10280/
它映射到我的URL,我在我的Redis To Go插件在Heroku中看到.
没有什么改变与Redis,我知道在昨天的工作和今天之间,当它没有,但我确实使用Mongo总部提出了一个Mongo数据库.也许这里有冲突吗？
任何帮助是赞赏.
编辑
我没有mongo init文件,我创建的唯一的mongo特定文件是我的config / mongoid.yml文件.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
我从主人安装了Mongo,并且正在运行导轨4.1.0.

完全跟踪错误如下：
