Sidekiq失去了redis连接...... 我的Sidekiq.rb

require 'sidekiq'
require 'sidekiq/web'
require 'sidekiq-cron'
require 'sidekiq-status'

Sidekiq.default_worker_options = { backtrace: true, retry: false }

Sidekiq.configure_server do |config|

  config.redis = { url: App.redis, size: 20 }

  if ENV['DATABASE_URL'].present?
    database_url = "#{ENV['DATABASE_URL']}?pool=25"
    ActiveRecord::Base.establish_connection(database_url)
  else
    ActiveRecord::Base.establish_connection
  end

  config.server_middleware do |chain|
    chain.add Sidekiq::Status::ServerMiddleware, expiration: 30.minutes # default
  end

  config.client_middleware do |chain|
    chain.add Sidekiq::Status::ClientMiddleware
  end
  Sidekiq::Cron::Job.load_from_hash YAML.load_file(Rails.root.join('config', 'sidekiq_cron.yml'))

end

Sidekiq.configure_client do |config|
  config.redis = { url: App.redis, size: 2 }
  config.client_middleware do |chain|
    chain.add Sidekiq::Status::ClientMiddleware
  end
end

我的puma.rb

workers Integer(ENV['PUMA_WORKERS'] || 2)
threads Integer(ENV['MIN_THREADS']  || 1), Integer(ENV['MAX_THREADS'] || 32)

preload_app!

rackup DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'

prune_bundler

on_worker_boot do
  if defined?(ActiveRecord::Base)
    ActiveSupport.on_load(:active_record) do
      ActiveRecord::Base.establish_connection
    end
    Rails.logger.info('Connected to ActiveRecord')
  end

  if defined?(REDIS)
    uri = URI.parse(App.redis)
    REDIS = Redis.new(host: uri.host, port: uri.port, password: uri.password)
    Rails.logger.info('Connected to Redis')
  end

  sidekiq_redis = { :url => ENV["REDIS_URL"] }
  Sidekiq.configure_server do |config|
    config.redis = sidekiq_redis
  end
  Sidekiq.configure_client do |config|
     config.redis = sidekiq_redis
  end
end

我该如何解决这个问题？

未定义的方法`multi＆＃39;为零：NilClass
