window 使用vagrant搭建开发开发环境

1.下载安装vagrant

2.下载安装 virtualbox

3.下载.box

4.初始化 vagrant box add {box-name} {box-url}

使用语句 vagrtant box list 查看创建的  name

5. 启动 vagrant up

6.修改Vagrantfile文件 如下

# -*- mode: ruby -*-
# vi: set ft=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.ssh.forward_agent = true

  config.vm.box = "keno_ubuntu"

  # 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  # `vagrant box outdated`.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: 3000, host: 8080

  # 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 "E:/rails", "/home/vagrant"

  # 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 = "2048"
  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

7.使用 vagrant reload 重新加载设置启动时会加载文件配置 常见的错误如下

 default: Error: Authentication failure. Retrying...

 default: Error: Authentication failure. Retrying...

 default: Error: Authentication failure. Retrying...

 default: Error: Authentication failure. Retrying...

解决办法:

Vagrant.configure("2") do |config|
  config.ssh.private_key_path = "~/.ssh/id_rsa"
  config.ssh.forward_agent = true
end

1. config.ssh.private_key_path is your local private key
2. Your private key must be available to the local ssh-agent. You can check with ssh-add -L, if it‘s not listed add it with ssh-add ~/.ssh/id_rsa
3. Don‘t forget to add you public key to ~/.ssh/authorized_keys on the Vagrant VM. You can do it copy-and-pasting or using a tool like ssh-copy-id

If still does not work try this:

1. Remove insecure_private_key file from c:\Users\USERNAME\.vagrant.d\insecure_private_key
2. Run vagrant up (vagrant will be generate a new insecure_private_key file)

In other cases, help is just a setting forward_agent in Vagrantfile:

Vagrant::Config.run do |config|
   config.ssh.forward_agent = true
end

二. 安装rails
