配置環境

While the setup is described well over at the WSL Distribution Switcher README file, we’ve made a quick 4-minute video to walk you through the setup and installation process. For an easier copy / paste operation, these are the basic steps taken:

1. Update your Windows 10 machine. Open an administrative PowerShell window and install the Windows Subsystem with this one-liner. A reboot will be required once finished.

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

1. Once rebooted, open a command line shell and run the following commands to install the default Ubuntu environment. This will lay down the foundations for our Kali install.

lxrun /install

1. Download “Git for Windows Setup” and install it on your Windows 10. And ensure git.exe

   in the cmd PATH.

2. Download and install Python on your Windows 10.And ensure python.exe in the cmd PATH.

3. Setup and install the WSL Switcher with Git for Windows in cmd on your Windows 10, download a Kali base, and extract it to disk:

git clone https://github.com/RoliSoft/WSL-Distribution-Switcher.git

cd WSL-Distribution
 
-Switcher

python get-prebuilt.py kalilinux/kali-linux-docker

python install.py rootfs_kalilinux_kali-linux-docker_latest.tar.gz

lxrun /setdefaultuser root

1. Now that Kali is set up on your Windows 10 machine, you can interact with it by running the “bash” command:

bash

1. At this point, you’re inside Kali and you can use it as you normally do–install packages, use tools, etc. We strongly recommend first running an update and upgrade:

export LANG=C
apt-get update
apt-get dist-upgrade

解決國內docker源速率慢或連線頻繁斷開問題

在安裝配置步驟的第5步中，我們要使用WSL-Distribution-Switcher中的python指令碼get-prebuilt.py下載後續所需的kalilinux/kali-linux-docker，但由於某些眾所周知的原因，指令碼中使用的國外docker庫連線較慢，且容易斷線，如下所示：

During handling of the above exception, another exception occurred:

所以我們將指令碼中的連線替換為國內docker映象源。

將指令碼中第56行和第92行中的urlhttps://registry.hub.docker.com替換為國內源https://registry.docker-cn.com：

# r = urllib.request.Request('https://registry.hub.docker.com/v2/%s/blobs/%s' % (fimage, layer['blobSum']))
# 替換為國內源https://registry.docker-cn.com
r = urllib.request.Request('https://registry.docker-cn.com/v2/%s/blobs/%s' % (fimage, layer['blobSum']))

# r = urllib.request.Request('https://registry.hub.docker.com/v2/%s/blobs/%s' % (fimage, layer['blobSum']))
# 替換為國內源https://registry.docker-cn.com
r = urllib.request.Request('https://registry.docker-cn.com/v2/%s/blobs/%s' % (fimage, layer['blobSum']))

修改之後再執行第5步中的python get-prebuilt.py kalilinux/kali-linux-docker命令，就可以順利下載了，如下所示：
