/ vagrant未填充文件

Question

我已vagrant init使用在OS X（10.11.4）上使用最新版本的VirtualBox（5.0.16 r105871）和最新ubuntu/trusty64盒装版本（v20160323.0.0）的默认配置配置了Vagrant（1.7.4 ）。

我的VM具有来宾添加项的匹配版本，但是我似乎无法使共享/vagrant目录正常工作。该/vagrant/目录存在于VM上，但如果ls在其上运行，则该目录完全为空。如果我touch有文件，它将显示在来宾中，/vagrant但不会同步回我计算机上的项目文件夹，并且在重新启动后消失。VirtualBox GUI显示共享文件夹：

  # 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
  # boxes at https://atlas.hashicorp.com/search.
  config.vm.box = "ubuntu/trusty64"

  # 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  # `vagrant box outdated`.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

  # 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

Answer 1

我已经弄清了问题所在-尽管/vagrant计算机上存在目录，但VirtualBox并未自动安装共享文件夹，尽管在GUI中将自动安装功能设置为“开”，并且调试输出指出确实安装了。

sudo mount -t vboxsf vagrant /vagrant手动运行可以解决此问题。我将此行放入用于启动工作的启动前脚本中，以启动服务器。

Answer 2

如果 VM 已关闭或从 VM 内部重新启动，则更有可能发生这种情况。

使用“vagranthalt”停止虚拟机，并使用“vagrantup”再次启动虚拟机。这应该会自动将其安装在 /vagrant 下
