如果空闲，Rails将停止响应

我一直有这个问题一段时间，并search了很多关于这一点，但似乎没有解决我的问题。

我有一个应用程序运行在Ruby on Rails的NGINX和UNICORN所有与Docker。

如果我运行应用程序（docker-compose），网站运行几分钟。 如果网站闲置了大约5到10分钟，并且我发送另一个请求，rails应用程序停止响应，从Unicorn处理超时。

奇怪的是，我开发的每一个应用程序都有相同的问题，这些应用程序唯一共同的就是Gemfile。

• 独angular兽nginx上游服务器无法启动
• 独angular兽请求排队
• 通过Web界面导航login
• 如何在linux虚拟机中运行节点项目？
• 全新安装后，gitlab无法运行

到目前为止我发现的是，当请求被发送时，NGINX收到这个请求，把它传递给Unicorn，Unicorn收到它并传递给ruby，这个没有回答，然后Unicorn给了我这个502坏请求。

我真的迷失在这一个。

这是我的NGINXconfiguration文件：

upstream applicationName { # Path to Puma SOCK file, as defined previously server unix:/tmp/applicationName.sock fail_timeout=0; } server { listen 80; server_name dev.applicationName.com.br; location / { autoindex on; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; # time out settings proxy_connect_timeout 159s; proxy_send_timeout 600; proxy_read_timeout 600; proxy_buffer_size 64k; proxy_buffers 16 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_pass_header Set-Cookie; proxy_redirect off; proxy_hide_header Vary; proxy_set_header Accept-Encoding ''; proxy_ignore_headers Cache-Control Expires; proxy_set_header Referer $http_referer; proxy_set_header Host $host; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://applicationName; } } 

这是我的独angular兽configuration

 @dir = File.expand_path(File.dirname(__FILE__)) + "/.." worker_processes 2 working_directory @dir timeout 10 listen File.join('/tmp/applicationName.sock') preload_app true# if ENV['RAILS_ENV'] != 'development' GC.respond_to?(:copy_on_write_friendly=) and GC.copy_on_write_friendly = true check_client_connection false before_fork do |server, worker| Signal.trap 'TERM' do puts 'Unicorn master intercepting TERM and sending myself QUIT instead' Process.kill 'QUIT', Process.pid end defined?(ActiveRecord::Base) and ActiveRecord::Base.connection.disconnect! end after_fork do |server, worker| Signal.trap 'TERM' do puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT' end defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection end 

这是Gemfile（没有错）

 source 'https://rubygems.org' gem 'rails', '4.2.4' gem 'unicorn-rails', '~> 2.2' gem 'pg' gem 'mysql2', '~> 0.3.18' gem 'sass-rails', '~> 5.0' gem 'uglifier', '>= 1.3.0' gem 'coffee-rails', '~> 4.1.0' gem 'duktape' gem 'jquery-rails' gem 'turbolinks' gem 'jbuilder', '~> 2.0' gem 'bootstrap-sass' gem 'devise' gem 'simple_form' gem 'minitest' gem "paperclip", "~> 4.3" gem 'aws-sdk', '< 2.0' gem 'mail_form', '~> 1.5.0.rc' gem 'sendgrid-ruby' gem 'zopim_rails' gem 'meta-tags' gem 'ckeditor' gem 'slick_rails' group :development do gem 'better_errors' gem 'binding_of_caller', :platforms=>[:mri_20] gem 'quiet_assets' gem 'rails_layout' gem 'spring-commands-rspec' gem 'web-console', '~> 2.0' gem 'spring' end group :production do gem 'therubyracer' end group :development, :test do gem 'factory_girl_rails' gem 'faker' gem 'pry-rails' gem 'pry-rescue' gem 'rspec-rails' gem 'rubocop' gem 'byebug' end group :test do gem 'capybara' gem 'database_cleaner' gem 'launchy' gem 'selenium-webdriver' end 

发生错误时，服务器上的日志显示了这一点：

并在开发日志上：
