我的服务器 Rails 工作正常，但 10 分钟后没有请求，它的响应是一个坏网关.我真的认为我的配置是有序的，但它不起作用.我没有更多的想法会发生什么.

My server Rails worker normally, but after 10 minutes without a request its response is a bad gateway. I really think my configurations are in order, but it don't work. I don't have more ideas what to is happening.

我的配置:

unicorn.rb:

unicorn.rb:

@dir = File.expand_path(File.dirname(__FILE__)) + "/.." worker_processes 2 working_directory @dir timeout 10 listen File.join('/tmp/nutrimais.sock') listen File.join('/tmp/nutrimais_2.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

nginx 配置:

upstream nutrimais { # Path to Puma SOCK file, as defined previously server unix:/tmp/nutrimais.sock max_fails=2 fail_timeout=10s; server unix:/tmp/nutrimais_2.sock; } server { listen 80; server_name dev.nutrimais.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_next_upstream http_502 timeout; proxy_next_upstream_timeout 0; proxy_next_upstream_tries 0; 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 nutrimais; } }

宝石文件:

登录时给出坏网关:

Started GET "/menus" for 127.0.0.1 at 2016-01-20 17:25:17 +0000 I, [2016-01-20T17:25:17.580380 #9] INFO -- : Processing by MenusController#index as HTML D, [2016-01-20T17:25:17.904933 #9] DEBUG -- : [1m[36mMenu Load (322.3ms)[0m [1mSELECT `menus`.* FROM `menus` ORDER BY created_at DESC[0m I, [2016-01-20T17:25:20.006674 #9] INFO -- : Started GET "/menus" for 127.0.0.1 at 2016-01-20 17:25:20 +0000

它停留在 Started GET 而不是什么都不做

It stays in Started GET and not does nothing

推荐答案

我发现发生了什么，linux 防火墙终止了连接.当我将数据库放在同一台机器上时，它可以正常工作.

I discovery what was happening, the linux firewall killed the connection. When I put the database in the same machine it is worked without trumbles.
