vagrant 中的同步文件夹未实时同步 [英] Synced folder in vagrant is not syncing in realtime

问题描述

我正在一个 vagrant 机器中设置一个同步文件夹，如下面的 cmd dump 所示，并期望每当我在主机上更新此文件夹中的文件时，更新也将反映在来宾机器中，但是这不会发生.

这是转储和它没有发生的证据(我创建了一个示例文件并通过将其中的文本从 test1 更改为 test2 来修改它):

它甚至应该实时同步吗?如果是，为什么不同步?

OS X 10.8.5、VirtualBox、coreos 框.

解决方案

在你的 Vagrantfile 中，同步的文件夹类型是默认的 vboxsf，但是，在 vagrant up stdout 中，它显示 rsync 类型，我认为您需要在配置文件中修复它.

假设您使用的是 rsync 类型，您的 Vagrantfile

中应该包含以下内容

Vagrant.configure("2") do |config|config.vm.synced_folder ".", "/vagrant", type: "rsync",rsync__exclude: ".git/"结尾

<块引用>

注意:默认情况下，rsync__auto 设置为 true，这意味着 rsync-auto 将监视并自动同步此文件夹.

运行 vagrant rsync-auto 并且目录应该在主机和来宾之间同步.

有关详细信息，请参阅 vagrant 文档.

I am setting up a synced folder in a vagrant machine like shown in cmd dump below and expect that whenever I update the files in this folder on the host machine the updates will be reflected inside guest machine too, however this is not happening.

Here is the dump and evidence of it not happening (I create a sample file and modify it by changing text in in it from test1 to test2):

mypc:~ user$ cd Projects/synctest/
mypc:synctest user$ ls
Vagrantfile
mypc:synctest user$ cat Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  # always use Vagrants insecure key
  config.ssh.insert_key = false

  # Setup box
  config.vm.box = "coreos-stable"

  # Setup shared folder
  config.vm.synced_folder ".", "/vagrant"

  # Setup memory usage
  config.vm.provider "virtualbox" do |v|
    v.memory = 2048
  end

  # Define `dev` vm
  config.vm.define :dev do |dev|
  end

  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
  end

end

Is it even supposed to sync realtime? If yes, why is not syncing?

Edit: OS X 10.8.5, VirtualBox, coreos box.

解决方案

In your Vagrantfile the synced folder type is default vboxsf, however, in the vagrant up stdout, it is showing rsync type, I think you need to fix it in the config file.

Assume that you are using rsync type, you should have the following in your Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.synced_folder ".", "/vagrant", type: "rsync",
    rsync__exclude: ".git/"
end

NOTE: By default, rsync__auto is set to true, which means rsync-auto will watch and automatically sync this folder.

Run vagrant rsync-auto and the directory should be in sync between host and guest.

Refer to vagrant docs for more information.
