向Heroku部署Rails + React + Puma + Nginx失败

Question

我想将RoR + React SPA作为一个项目部署到heroku。作为典型的生产环境，请使用Nginx作为Web服务器，使用用户Puma作为应用程序服务器。

我试图遵循readme的https://github.com/heroku/heroku-buildpack-nginx。

但是部署后，heroku会弹出一个错误

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

下面是我的配置

heroku buildpacks

heroku/nodejs # index 1
heroku/ruby   # index 2
https://github.com/heroku/heroku-buildpack-nginx.git # index 3

Procfile

release: bundle exec rails db:migrate
web: bin/start-nginx bundle exec puma -C config/puma.rb

config / puma.rb

max_threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
min_threads_count = ENV.fetch("RAILS_MIN_THREADS") { max_threads_count }
threads min_threads_count, max_threads_count

environment ENV.fetch("RAILS_ENV") { "development" }
plugin :tmp_restart

bind ENV.fetch('PUMA_SOCK') { 'unix:///tmp/nginx.socket' }

on_worker_fork do
  FileUtils.touch('/tmp/app-initialized')
end

config / nignx.conf.erb =>我删除了此文件的不重要配置，因为它太长了

http {
    upstream app_server {
        server unix:/tmp/nginx.socket fail_timeout=0;
    }

    server {
        listen <%= ENV["PORT"] %>;
        server_name _;
        keepalive_timeout 5;

        location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;
            proxy_pass http://app_server;
        }
    }
}
