为什么SSL只能在Puma开发应用程序上运行而不能在生产环境中运行时使用？

Question

我有一个在开发模式下运行的Puma应用程序，我可以使用SSL在Nginx服务器后面进行配置，但是当我尝试对在生产模式下运行的Puma应用程序执行相同操作时，就会遇到麻烦。

相关代码：

nginx.conf：

upstream puma_lbm_app {
  server lbm:40000;
}

server {
  listen 40000 ssl default_server;

  server_name         www.*.com;
  ssl_certificate     /etc/ssl/LBM/certs/server.crt;
  ssl_certificate_key /etc/ssl/LBM/private/server.key;
  ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers         HIGH:!aNULL:!MD5;

  client_max_body_size 4G;
  keepalive_timeout 10;

  error_page 500 502 504 /500.html;
  error_page 503 @503;

  server_name localhost puma_lbm_app;
  root /usr/src/app/public;
  try_files $uri/index.html $uri @puma_lbm_app;

  location @puma_lbm_app {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    fastcgi_param   HTTPS               on;
    fastcgi_param   HTTP_SCHEME         https;

    proxy_pass https://puma_lbm_app;
    # limit_req zone=one;
    access_log /usr/src/app/log/nginx.access.log;
    error_log /usr/src/app/log/nginx.error.log;
  }
}

puma.rb：

# Puma can serve each request in a thread from an internal thread pool.
# The `threads` method setting takes two numbers a minimum and maximum.
# Any libraries that use thread pools should be configured to match
# the maximum value specified for Puma. Default is set to 5 threads for minimum
# and maximum, this matches the default thread size of Active Record.
#
threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }.to_i
threads threads_count, threads_count

# Specifies the `port` that Puma will listen on to receive requests, default is 3000.
#
port ENV.fetch("PORT") { 40000 }

# Specifies the `environment` that Puma will run in.
#
environment ENV.fetch("RAILS_ENV") { "production" } # this is development when running our dev Puma app
bind 'tcp://0.0.0.0'

# Specifies the number of `workers` to boot in clustered mode.
# Workers are forked webserver processes. If using threads and workers together
# the concurrency of the application would be max `threads` * `workers`.
# Workers do not work on JRuby or Windows (both of which do not support
# processes).
#
# workers ENV.fetch("WEB_CONCURRENCY") { 2 }

# Use the `preload_app!` method when specifying a `workers` number.
# This directive tells Puma to first boot the application and load code
# before forking the application. This takes advantage of Copy On Write
# process behavior so workers use less memory. If you use this option
# you need to make sure to reconnect any threads in the `on_worker_boot`
# block.
#
# preload_app!

# The code in the `on_worker_boot` will be called if you are using
# clustered mode by specifying a number of `workers`. After each worker
# process is booted this block will be run, if you are using `preload_app!`
# option you will want to use this block to reconnect to any threads
# or connections that may have been created at application boot, Ruby
# cannot share connections between processes.
#
# on_worker_boot do
#   ActiveRecord::Base.establish_connection if defined?(ActiveRecord)
# end

# Allow puma to be restarted by `rails restart` command.
plugin :tmp_restart

用于生产的dockerfile：

FROM ruby:2.3-alpine

RUN apk --update add --virtual build-dependencies build-base ruby-dev \
    openssl-dev libxml2-dev libxslt-dev sqlite libc-dev linux-headers nodejs \
    tzdata sqlite-dev bind-tools curl postgresql-client \
    postgresql-dev

RUN gem install bundler

ENV RAILS_ENV production

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app
ADD http://browserconfig.*.com/*-certs/*-ca-bundle.crt /etc/ssl/certs/ca-bundle.crt
RUN bundle install

EXPOSE 40000

CMD bundle exec puma -C config/puma.rb

用于开发的dockerfile：

FROM ruby:2.3-alpine

RUN apk --update add --virtual build-dependencies build-base ruby-dev \
    openssl-dev libxml2-dev libxslt-dev sqlite libc-dev linux-headers nodejs \
    tzdata sqlite-dev bind-tools curl postgresql-client \
    postgresql-dev

RUN gem install bundler

ENV RAILS_ENV development

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app
ADD http://browserconfig.*.com/*-certs/*-ca-bundle.crt /etc/ssl/certs/ca-bundle.crt
RUN bundle install
RUN rake db:migrate

EXPOSE 40000

CMD bundle exec puma -C config/puma.rb

通过对nginx.conf和puma.conf的细微调整，我可以得到307s，502s ...但是它永远不会像应用程序在开发中运行时那样显示得很好。

所以它一直在工作。 问题出在生产中而不是主持“ Yay！ 您正在开发显示的Rails页面上。 我们也在与Postman进行测试，并且在处理标头方面看到了一些单独的问题。
