在windows10的WSL里使用vagrant+Hyper-V

在上一篇文章里Win10 Hyper-V和VirtualBox冲突的问题，提到了Win10的Hyper-V和VirtualBox冲突的问题，对于比较习惯于使用VirtualBox，或者Vagrant+VirtualBox的同学来说，最简单的就是关掉Hyper-V，但是关掉以后估计将来使用WSL2会是个问题。

今天在公司折腾了一下午，在win10的WSL里安装了Vagrant，并且启动Hyper-V作为Vagrant的provider来创建虚拟机，再加上VScode的远程开发（VScode remote WSL），真的是非常方便。如果将来升级到WSL2，原生能在WSL里安装docker就更好了。下面我就把安装配置的过程记录一下。

1. 安装WSL

没什么好说的，按照微软的官方文档即可，我选择的是Ubuntu 18.04。

https://docs.microsoft.com/en-us/windows/wsl/install-win10

2. 打开 Hyper-V

以管理员身份打开PowerShell，并且执行下面的命令把当前用户添加到Hyper-V的管理员组。

([adsi]”WinNT://./Hyper-V Administrators,group”).Add(“WinNT://$env:UserDomain/$env:Username,user”)

然后打开 Hyper-V:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

按照系统提示，需要重启电脑

3. 安装 vagrant

进入WSL，从Vagrant的下载页面下载最新的Debian 64-bit版: https://www.vagrantup.com/downloads.html

CD到deb文件（比如vagrant_2.2.4_x86_64.deb）所在的目录，然后执行：

sudo dpkg -i vagrant_2.2.4_x86_64.deb

默认情况下，Vagrant是无法访问Windows主机里的Hyper-V特性的，首先通过的下面的命令让Vagrant能够access windows。

echo 'export VAGRANT_WSL_ENABLE_WINDOWS_ACCESS="1"' >> ~/.bashrc

然后设置Hyper-V为vagrant默认的provider。

echo 'export VAGRANT_DEFAULT_PROVIDER="hyperv"' >> ~/.bashrc

4. 测试 Vagrant

首先初始化一个Centos7的Vagrantfile

penxiao@WPU8L0042502:~$ mkdir centos
penxiao@WPU8L0042502:~$ cd centos/
penxiao@WPU8L0042502:~/centos$ ls
penxiao@WPU8L0042502:~/centos$ vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
penxiao@WPU8L0042502:~/centos$ ls
Vagrantfile
penxiao@WPU8L0042502:~/centos$ vagrant status
Current machine states:

default                   not_created (hyperv)

修改Vagrantfile

增加一行 config.vm.box_download_insecure = true 保存退出

config.vim.box = "centos/7"
config.vim.box_download_insecure = true

启动，SSH进入，测试。
