使用Puma部署在Elastic Beanstalk上的Rails应用程序失败-每个请求502错误 [英] Rails application deployed on Elastic Beanstalk with Puma fails - 502 errors on every request

问题描述

我刚刚将Rails应用程序部署到Elastic Beanstalk，并且每个请求都给我一个502错误.

I just deployed a Rails app to Elastic Beanstalk, and every request is giving me a 502 error.

这是/var/logs/nginx/error.log的内容

Here's the contents of /var/logs/nginx/error.log

我认为彪马正在跑步-

[ec2-user@ip-172-31-44-135 nginx]$ ps aux | grep puma

pumaconf.rb

pumaconf.rb

directory '/var/app/current'
threads 8, 32
workers %x(grep -c processor /proc/cpuinfo)
bind 'unix:///var/run/puma/my_app.sock'
stdout_redirect '/var/log/puma/puma.log', '/var/log/puma/puma.log', true
daemonize false

有人知道发生了什么事吗?

Anyone know what's going on?

推荐答案

我遇到了相同的错误，并将这两行添加到config/puma.rb中解决了该问题:

I faced the same error and adding these two lines to config/puma.rb fixed the problem:

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

在执行此步骤后，我遇到了另一个错误，即添加ENV值非常简单.

After this step I faced another error to add ENV values, which is very straight forward.

希望这会有所帮助.
