在vagrant中无法连接localhost：3000 ruby​​ on rails

Question

我尝试在windows

中连接localhost：3000

rails server在vagrant（ubuntu 14.10）

中运行

portforwarding已完成

什么时候，我试过了 在ubunutu lynx 127.0.0.1:3000，它有效

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

刚刚显示ERR_CONNECTION_REFUSED

在cmd中，我运行netstat -t结果为：3000 TIME_WAIT

我该如何解决这个问题？

这是我的'Vagrantfile'

Vagrant.configure(2) do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at

  # Every Vagrant development environment requires a box. You can search for

  config.vm.box = "ubuntu 14.10"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # 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
  # within the machine from a port on the host machine. In the example below,
  # 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
  # your network.
  # 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.
  # config.vm.synced_folder "../data", "/vagrant_data"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   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|
  #   push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"
  # end

  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the

编辑： 我尝试了仅限主机的网络适配器，并尝试在主机中连接192.168.33.10:3000 仍然无法连接。一个奇怪的事情，我可以在主机上发送Ping到192.168.33.10并且回复了。我不知道问题是什么。我很困惑。请有人帮助我:(

Answer 1

解决方案正在运行以下代码来启动服务器：

rails s -b 0.0.0.0

我从另一篇文章中找到了关于同一问题的解决方案。 回答者说'你想确保服务器绑定到0.0.0.0，以便所有接口都可以访问它。＆＃34;

我希望这篇文章可以帮助遇到同样问题的人：）

Answer 2

您可以在此处找到原因：http://edgeguides.rubyonrails.org/4_2_release_notes.html

  

由于Rack的更改，rails服务器现在侦听localhost而不是默认情况下的0.0.0.0

如果您想使用rails s代替rails s -b 0.0.0.0，可以修改/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

此外，我做了类似的事情，以便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
