ruby - 在 Heroku 中的 Puma 上部署 Rails 应用程序时出错

我正在尝试部署在 Puma 和 jruby 上运行的 Rails 应用程序。 Procfile如下

web: bundle exec puma -C config/puma.rb -p $PORT -e $RACK_ENV

Puma 的配置放在

config/puma.rb

if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
  workers Integer(ENV['PUMA_WORKERS'] || 4)
end

threads Integer(ENV['MIN_THREADS']  || 1), Integer(ENV['MAX_THREADS'] || 4)

rackup      DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
preload_app!

on_worker_boot do
  # worker specific setup
  ActiveSupport.on_load(:active_record) do
    config = ActiveRecord::Base.configurations[Rails.env] ||
                Rails.application.config.database_configuration[Rails.env]
    config['pool'] = ENV['MAX_THREADS'] || 16
    ActiveRecord::Base.establish_connection(config)
  end
end

我对 worker 进行条件初始化的原因是因为 Heroku 提示(或者可能是 Puma) worker 模式不适用于 JRuby 和 Windows；总之，

我在 heroku 上注意到的奇怪行为是(不同于)我的本地环境，集群 Puma 实例启动时没有任何问题，并选择两个不同的端口进行绑定(bind)，即 3000 和 5000。

但是，在生产环境中，即 Heroku，这会导致崩溃

当我在我的笔记本电脑上运行时，没有看到这种奇怪的启动行为。

我让 puma 在 Heroku 中处理 jruby 的唯一方法是通过这个设置

if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
  workers Integer(ENV['PUMA_WORKERS'] || 4)
  port ENV['PORT'] || 3000
  environment ENV['RACK_ENV'] || 'development'
end

threads Integer(ENV['MIN_THREADS']  || 1), Integer(ENV['MAX_THREADS'] || 4)

rackup      DefaultRackup
preload_app!

on_worker_boot do
  # worker specific setup
  ActiveSupport.on_load(:active_record) do
    config = ActiveRecord::Base.configurations[Rails.env] ||
                Rails.application.config.database_configuration[Rails.env]
    config['pool'] = ENV['MAX_THREADS'] || 16
    ActiveRecord::Base.establish_connection(config)
  end
end

即如果端口和环境指令在 if block 之外，Heroku 以某种方式试图在同一端口上运行两个实例，这显然会导致崩溃。

我是否遗漏了这里的任何配置或者基本上以集群模式运行(我什至尝试在 Ruby 2.0.0 而不是 JRuby 上运行)在 Heroku 中是不可能的

* 更新 *

配置文件

web: bundle exec puma -C config/puma.rb

config/puma.rb

if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
  workers Integer(ENV['PUMA_WORKERS'] || 4)
end

threads Integer(ENV['MIN_THREADS']  || 1), Integer(ENV['MAX_THREADS'] || 16)

rackup      DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
preload_app!

on_worker_boot do
  # worker specific setup
  ActiveSupport.on_load(:active_record) do
    config = ActiveRecord::Base.configurations[Rails.env] ||
                Rails.application.config.database_configuration[Rails.env]
    config['pool'] = ENV['MAX_THREADS'] || 16
    ActiveRecord::Base.establish_connection(config)
  end
end

条件 block 的原因(引自最初的问题描述

the reason I have a conditional initialisation for workers is because Heroku complains (or may be Puma) worker mode is not available for JRuby and Windows;

和错误日志(即使我删除了 JRUBY，条件工作 block )并尝试在集群模式下运行

最佳答案

我刚刚和你遇到了同样的问题。

好像和端口的重复定义有关

首先在 Procfile 中，然后在 config/puma.rb 文件中

我从 Procfile(以及环境)中删除了端口，因为它已经在 config/puma.rb 中定义。

web: bundle exec puma -C config/puma.rb
