Ruby on rails 轨道&x2B；美洲狮+；sidekiq+；rabbitMQ（bunny gem），在heroku上运行时遇到连接问题,ruby-on-rails,postgresql,heroku,rabbitmq,sidekiq,Ruby On Rails,Postgresql,Heroku,Rabbitmq,Sidekiq,我正在用Rails+Puma+sidekiq+rabbitMQ（兔子宝石）做一个原型初始化者/sidekiq.rb require 'sidekiq' Sidekiq.configure_client do |config| config.redis = { :size => 1 } end Sidekiq.configure_server do |config| end 美洲狮 threads_count = ENV.fetch("RAILS_MAX_THREADS") {

我正在用Rails+Puma+sidekiq+rabbitMQ（兔子宝石）做一个原型

初始化者/sidekiq.rb

require 'sidekiq'

Sidekiq.configure_client do |config|
  config.redis = { :size => 1 }
end

Sidekiq.configure_server do |config|

end

美洲狮

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
threads threads_count, threads_count

port ENV.fetch("PORT") { 3000 }

environment ENV.fetch("RAILS_ENV") { "development" }

workers ENV.fetch("WEB_CONCURRENCY") { 2 }

plugin :tmp_restart

Procfile.rb

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -c 2 -v

这是从队列中获取消息的使用者部分

初始化器/subscriber.rb

connection = Bunny.new(ENV['CLOUDAMQP_URL'])

connection.start # start a communication session with the amqp server

channel = connection.channel()

queue = channel.queue('order-queue', durable: true)

puts ' [*] Waiting for messages. To exit press CTRL+C'

queue.subscribe(manual_ack: true, block: true) do |delivery_info, 
properties, payload|
  puts " [x] Received #{payload}"
  puts " [x] Done"

  channel.ack(delivery_info.delivery_tag, false)
  # Call sidekiq worker to do task
  callSidekiqWorker.perform_async(payload)
end

在callSidekiqWorker中，我有一个函数可以从其他数据库获取连接

sidekiqWorker.rb

def perform(params)
        # Get Database Connection
        connection = get_db_connection
        params.each do |param|
            query1 = "..."
            connection.execute(query1)
            query2 = "..."
            connection.execute(query2)
            ............
        end
        ActiveRecord::Base.remove_connection(connection)
end

def get_db_connection
    ActiveRecord::Base.establish_connection(
        :adapter => 'postgresql',
        :database => ENV["DB_NAME"],
        :username => ENV["USERNAME"],
        :password => ENV["PASSWORD"],
        :host => ENV["HOST"]
    ).connection
end

所以当我在heroku运行这个时，我得到了这个错误

但当重试时，这将起作用。我的配置是否正确？连接池是否存在任何问题？

您是否能够解决这个问题？运行到同一个issueYeah，而不是这个活动连接，我将DB附加到这个应用程序中，并创建了所有的伪类
