让Vagrant在Windwos下支持使用NFS/SMB共享文件夹从而解决目录共享IO缓慢的问题

此问题是在拥有相同配置的环境中，项目在win10跑的慢而在win7就正常的情况下发现的，一步步调试之后发现是文件操作的相关行为变的很慢，于是考虑到可能是系统问题，后来在如下链接找到了解决办法：http://www.iamle.com/archives/2011.html

1。nfs方式

安装vagrant 插件 vagrant-winnfsd

$ vagrant plugin install vagrant-winnfsd

但是这样安装会出现以下错误

Installing the 'vagrant-winnfsd' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:
 
An error occurred while installing childprocess (0.5.), and Bundler cannot continue.
Make sure that `gem install childprocess -v '0.5.8'` succeeds before bundling.
 
Warning: this Gemfile contains multiple primary sources. Using `source` more than once without a block is a security risk, and may result in installing unexpected gems. To resolve this warning, use a block to indicate which gems should come from the secondary source. To upgrade this warning to an error, run `bundle config disable_multisource true`.Gem::RemoteFetcher::FetchError: Errno::ECONNABORTED: An established connection was aborted by the software in your host machine. - SSL_connect (https://rubygems.org/gems/childprocess-0.5.8.gem)

看来是缺少childprocess-0.5.8.gem这个东西
索性把需要的包都下载到本地,然后本地安装
https://rubygems.org/gems/childprocess-0.5.8.gem
https://rubygems.org/gems/vagrant-winnfsd-1.1.0.gem
然后

vagrant plugin install childprocess-0.5..gem
vagrant plugin install vagrant-winnfsd-1.1..gem

看一看安装好的插件

$ vagrant plugin list
childprocess (0.5.)
  - Version Constraint: 0.5.
vagrant-share (1.1., system)
vagrant-winnfsd (1.1.)
  - Version Constraint: 1.1.

编辑项目下的Vagrantfile文件

Vagrant.configure('') do |config|
  # other config here
  config.vm.network "private_network", ip: "192.168.33.10"
 
  #winfsd
  config.winnfsd.logging = "on"
  config.winnfsd.uid =
  config.winnfsd.gid =
  config.vm.synced_folder "./", "/vagrant", type: "nfs"
end

2.SMB方式

Vagrant.configure('') do |config|
  # other config here
  config.vm.network "private_network", ip: "192.168.33.10"
 
  #SMB
  config.vm.synced_folder "./", "/vagrant", type: "smb",
      smb_username: "母鸡Windows帐号",
      smb_password: "母鸡Windows密码",
      owner: "www",
      group: "www"
      #mount_options: ["dmode=775,fmode=664"]
end

启动vagrant虚拟机, 注意启动过程当中需要输入windwos系统的帐号和密码

d:\projects>

发现vagrant开启了一个名称为c30268623ba3dedeaa9f098b570dca21的共享
这个地方有个安全大坑,共享权限居然是Everyone!所以注意母鸡Windows上是否有其他帐号能访问!
我把c30268623ba3dedeaa9f098b570dca21本共享的权限改了,发现vagrant还是会把权限设置为Everyone
如果有开启其他普通帐号,guest什么的这里有安全隐患

C:\Users\Administrator>net share
 
共享名       资源                            注解
 
-------------------------------------------------------------------------------
IPC$                                         远程 IPC
c30268623ba3dedeaa9f098b570dca21
             D:\projects
命令成功完成。

为了防止smb共享剔除不活动的连接需要执行以下命令让系统不要自动踢掉不活动的连接
net config server /autodisconnect:-1

vagrant不会自动删除共享,要删除共享使用命令
net share c30268623ba3dedeaa9f098b570dca21 /delete
