Question

我正在尝试学习Ruby on Rails，我已按照此页面的说明在我的MAC上安装了rails。到目前为止一切正常，但localhost：3000无法正常工作。我也尝试SSH地址：127.0.0.1:2222但不能正常工作。

我试图找出问题是什么并让它发挥作用。有人知道如何修理它吗？

Rails 4.2.0 Ruby 2.0.0p598（2014-11-13修订版48408）[x86_64-darwin13.4.0]

$ vagrant up
enter code here

    default: Adapter 1: nat

GuestAdditions 4.3.20 running --- OK.

    default: /vagrant => /Users/Arturo/Desktop/Vagrant/myVM

==> default: Machine already provisioned. Run `vagrant provision` or use the `--provision`
==> default: to force provisioning. Provisioners marked to run always will still run.

它像这样出现

   $ rails server

=> Booting WEBrick
=> Rails 4.2.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[2015-01-12 07:41:04] INFO  WEBrick 1.3.1
[2015-01-12 07:41:04] INFO  ruby 2.0.0 (2013-06-27) [x86_64-linux]
[2015-01-12 07:41:04] INFO  WEBrick::HTTPServer#start: pid=3021 port=3000

我找不到任何错误修复。有人可以告诉我从哪里开始修复。

Vagrantfile

# -*- mode: ruby -*-

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.

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
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.
  config.vm.box = "centos64box"

  # 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  # `vagrant box outdated`.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 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: 80, host: 8080
  config.vm.network :"forwarded_port", guest: 3000, host: 3000

  # 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 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
  # documentation for more information about their specific syntax and use.
  # config.vm.provision "shell", inline: <<-SHELL
  #   sudo apt-get update
  #   sudo apt-get install -y apache2
  # SHELL
end

SSH进入你的流浪汉并运行这个命令：

ipaddr

从那里拿走流浪汉的ip地址。运行rails server并在浏览器中

vagrant-ip-address:3000

Ruby on rails无法访问MAC上的http：/ localhost：3000
