我试图在 Windows 中连接 localhost:3000

rails 服务器在 vagrant 中运行（ubuntu 14.10）

端口转发完成

什么时候，我 lynx 127.0.0.1:3000在 ubunutu 中尝试过，它有效

但是，在 Windows 中，我也无法连接 localhost:3000, 127.0.0.1:3000

刚刚显示 ERR_CONNECTION_REFUSED

在cmd中，我运行netstat -t的结果是：3000 TIME_WAIT

我怎么解决这个问题？

这是我的“流浪文件”

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  # config.vm.network "private_network", ip: "192.168.33.10"

  # Create a forwarded port mapping which allows access to a specific port

  # accessing "localhost:8080" will access port 80 on the guest machine.
  config.vm.network "forwarded_port", guest: "3000", host: "3000"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on

  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.

  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
  # such as FTP and Heroku are also available. See the documentation at
  # https://docs.vagrantup.com/v2/push/atlas.html for more information.
  # config.push.define "atlas" do |push|

编辑：我尝试了 Host-only 网络适配器，我尝试在主机中连接 192.168.33.10:3000 仍然无法连接。一件奇怪的事情，我可以在主机中发送 Ping 到 192.168.33.10 并得到回复。我不知道问题是什么。我很困惑。有人帮助我，请:(

该解决方案正在运行以下代码来启动您的服务器：

rails s -b 0.0.0.0

我从另一篇关于同样问题的帖子中找到了这个解决方案。回答者说'你需要确保服务器绑定到 0.0.0.0 以便所有接口都可以访问它。

我希望这篇文章能帮助遇到同样问题的人:)

你可以在这里找到原因：http: //edgeguides.rubyonrails.org/4_2_release_notes.html

由于 Rack 的变化，rails 服务器现在默认监听 localhost 而不是 0.0.0.0

如果你想使用rails s而不是rails s -b 0.0.0.0，你可以编辑/config/boot.rb：

ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)

require 'bundler/setup' if File.exist?(ENV['BUNDLE_GEMFILE'])

require 'rails/commands/server'

module Rails
  class Server
    alias :default_options_alias :default_options
    def default_options
      default_options_alias.merge!(:Host => '0.0.0.0')
    end
  end
end

我也做了这样的事情，所以 Guard 以这种方式开始： guard 'rails', force_run: true, host: '0.0.0.0' do watch('Gemfile.lock') watch(%r{^(config|lib)/.*}) end
