Can't connect to redis on heroku

Question

I'm using sidekiq with active_job in my rails application. The job currently works but I am unable to get connect to the Redis when deploying to heroku. In heroku I have the RedisToGo addon. When pushing to heroku I get the following error.

error

/app/vendor/bundle/ruby/2.2.0/gems/redis-3.2.1/lib/redis/client.rb:331:in `rescue in establish_connection': Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED) (Redis::CannotConnectError)

config/application.rb

config.after_initialize do
  PasswordAgingJob.perform_later
  SetOffCallJob.perform_later
end

config/initializers/redis.rb

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

config/initializers/active_job.rb

ActiveJob::Base.queue_adapter = :sidekiq

Answer 1

Set REDIS_PROVIDER to the name of the env var with your Redis URL.

Type this: heroku config:set REDIS_PROVIDER=REDISTOGO_URL . Restart.

Answer 2

在heroku配置中设置REDIS_URL帮助我解决：

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

Answer 3

You must set the REDISTOGO_URL on Heroku.

Click on Settings , and then Reveal Config Vars .

Answer 4

将 REDIS_URL 设置为 redis://@pike.redistogo.com:10731/ 似乎对我有用。
