在heroku上部署简单的机架应用程序时出现应用程序错误

标签： ruby-on-rails heroku rack heroku-toolbelt heroku-san

我正在尝试在heroku上部署我的应用程序 它包含5个文件 1.config.ru 代码

require 'rack'
require './myapp'

run MyApp.new

2.Gemfile 代码

source "http://rubygems.org"
gem 'grape'
gem 'sequel'
gem 'heroku'
gem 'rake'
gem 'pg'
gem 'rack'
group :test do
  gem "rspec", "~> 2.12.0"
  gem "rack-test", "~> 0.6.2"
  gem "rspec-core", "~> 2.12.2"
  gem "rspec-expectations", "~> 2.12.1"
  gem "rspec-mocks", "~> 2.12.1"
  gem "capybara", "~> 2.0.2"
  gem "nokogiri", "~> 1.5.6"
end

3.Gemfile.lock自动创建 4.myapp.rb代码

# my_app.rb
class MyApp
  def call env
    [200, {"Content-Type" => "text/html"}, ["Hello Rack Participants"]] 
  end
end

5.Procfile with code 

web: bundle exec rackup config.ru

然后我调用bundle install

之后的机架配置 它按预期完美地工作 但之后我尝试在heroku上部署它并获得应用程序错误 我执行了以下命令

git init
git add .
git commit -m "initial commit"
heroku create
git push heroku master
heroku open

打开网页浏览器时出现应用程序错误 当我运行命令heroku日志 然后它给我记录日志

2013-02-04T05:34:17+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=quiet-caverns-8170.herokuapp.com fwd=121.245.34.235 dyno= queue= wait= connect= service= status=503 bytes=

任何人都可以帮助我为什么我在heroku上得到这个错误并跳到它来纠正它？

这是heroku的完整日志

看起来您没有为要运行的应用指定正确的端口。尝试将Procfile切换为以下

web: bundle exec rackup config.ru -p $PORT -E $RACK_ENV

有关类似问题，请参阅Deploy Sinatra app on Heroku和Deploying sinatra app (with config.ru) on heroku cedar stack。

您没有绑定$PORT中的端口，因此我们会终止您的进程。您必须将Procfile更改为包含-p $PORT。
