配置Puma和Sidekiq

ruby-on-railssidekiqpuma
4

可能更多的是试图克服学习曲线和实际代码问题。如果它看起来很新手，我感到抱歉，目前我在生产环境中遇到了这个错误。

基本上，我一直收到"redis池太小"的错误提示，但我不知道从哪里开始。我甚至对如何准确配置Puma与Sidekiq或任何关于配置后的扩展等方面都感到困惑。

下面是我的配置和错误信息：

ProcFile web: bundle exec puma -C config/puma.rb worker: bundle exec sidekiq -e production -C config/sidekiq.yml

Sidekiq init

if Rails.env.production?

  Sidekiq.configure_client do |config|
    config.redis = { url: ENV['REDIS_URL'], size: 2 }
  end

  Sidekiq.configure_server do |config|
    config.redis = { url: ENV['REDIS_URL'], size: 20 }

    Rails.application.config.after_initialize do
      Rails.logger.info("DB Connection Pool size for Sidekiq Server before disconnect is: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      ActiveRecord::Base.connection_pool.disconnect!

      ActiveSupport.on_load(:active_record) do
        config = Rails.application.config.database_configuration[Rails.env]
        config['reaping_frequency'] = ENV['DATABASE_REAP_FREQ'] || 10 # seconds
        # config['pool'] = ENV['WORKER_DB_POOL_SIZE'] || Sidekiq.options[:concurrency]
        config['pool'] = 16
        ActiveRecord::Base.establish_connection(config)

        Rails.logger.info("DB Connection Pool size for Sidekiq Server is now: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      end
    end
  end

end

Redis初始化

   if ENV["REDISTOGO_URL"]
    $redis = Redis.new(:url => ENV["REDISTOGO_URL"])
    end

puma.rb

   workers Integer(ENV['WEB_CONCURRENCY'] || 2)  
    threads_count = Integer(ENV['MAX_THREADS'] || 1)  
    threads threads_count, threads_count

    preload_app!

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

    # Because we are using preload_app, an instance of our app is created by master process (calling our initializers) and then memory space
    # is forked. So we should close DB connection in the master process to avoid connection leaks.
    # https://github.com/puma/puma/issues/303
    # https://dev59.com/X2Mm5IYBdhLWcg3wDrtR
    # http://www.rubydoc.info/gems/puma/2.14.0/Puma%2FDSL%3Abefore_fork
    # Dont have to worry about Sidekiq's connection to Redis because connections are only created when needed. As long as we are not
    # queuing workers when rails is booting, there will be no redis connections to disconnect, so it should be fine.
    before_fork do  
      puts "Puma master process about to fork. Closing existing Active record connections."
      ActiveRecord::Base.connection.disconnect!
    end

    on_worker_boot do  
      # Worker specific setup for Rails 4.1+
      # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
      ActiveRecord::Base.establish_connection
    end

             Your Redis connection pool is too small for Sidekiq to work. Your pool has 20 connections but really needs to have at least 22

在你的configure_*代码块中删除size:属性。让Sidekiq为您管理大小。

自从我禁用了大小属性以后，我一直在收到一个错误，我已经更新了我的代码，并附上了我收到的错误信息。当我把大小属性加回去后，似乎Redis工作得很好，但是后台处理的操作，例如邮件程序，没有移动出队列。我已经按照示例配置了Active Job和Mailer与Sidekiq，并尝试着让队列执行，包括创建不同类型的队列，以便不使用默认队列运行。 - leafshinobi25

移除大小限制，将并发数从20降低到15，或者升级您的Redis计划。 - Mike Perham
感谢您迄今为止的帮助，Perham先生，请问您能否分享一个关于如何在Heroku配置时确定并发性的文档链接。将并发性从20更改为15并没有帮助，我仍然收到“ERROR: heartbeat: ERR max number of clients reached 3 TID-ovd1lea0g ERROR: ERR max number of clients reached”错误提示。 - leafshinobi25
