使用Puma部署在Elastic Beanstalk上的Rails應用程序失敗 - 每次請求都會出現502錯誤

我剛剛部署了一個Rails應用程序到Elastic Beanstalk，並且每個請求都給我一個502錯誤。使用Puma部署在Elastic Beanstalk上的Rails應用程序失敗 - 每次請求都會出現502錯誤

這裏的/var/logs/nginx/error.log的內容

我認爲彪馬運行 -

pumaconf.rb

bind 'unix:///var/run/puma/my_app.sock' 
stdout_redirect '/var/log/puma/puma.log', '/var/log/puma/puma.log', true 
daemonize false

任何人都知道這是怎麼回事？

請提供您的pumaconf.rb 看來，nginx尋找有代表性的彪馬套接字文件 –

@StanislavMekhonoshin添加！ – chintanparikh

我遇到類似的問題。你找到解決辦法嗎？ – Disha

你的日誌文件中的這一行意味着你錯誤地配置了你的nginx。

upstream: "http://unix:///var/run/puma/my_app.sock:/get"

其實nginx嘗試使用unix域套接字作爲HTTP url。

不能說什麼是錯的，沒有它你的nginx的配置，但你應該有這樣的事情：

upstream backend { 
    server backend1.example.com weight=5; 
    server 127.0.0.1:8080  max_fails=3 fail_timeout=30s; 
    server unix:/tmp/backend3; 

    server backup1.example.com backup; 
}

你也應該看看這個nginx的文檔http://nginx.org/en/docs/http/ngx_http_upstream_module.html

nginx配置所在的任何想法？ – chintanparikh

我沒有EBS的經驗，但通常nginx配置位於/ etc/nginx/sites-enabled/* 但是我試着改變'bind'unix：/// var/run/puma /例如，my_app.sock'到'bind'tcp：//0.0.0.0:8080''。這將是更容易 –

的AWS文檔要求將美洲獅寶石安裝爲應用程序的一部分。

以下添加到您的Gemfile酌情：

group :production do 
    gem 'puma' 
end

我仍然得到[錯誤]（http://stackoverflow.com/questions/37472304/rails-elastic-beanstalk-connection-time-out-puma-server）。似乎請求首先在時間戳之前前往nginx。不知道如何解決這個問題 –

我面臨同樣的錯誤，並添加以下兩行config/puma.rb解決了這一問題：

bind "unix:///var/run/puma/my_app.sock" 
pidfile "/var/run/puma/my_app.sock"

這一步我面臨的另一個錯誤後添加ENV值，這是非常簡單的。

希望這會有所幫助。
