## 下载脚本
wget --no-check-certificate -qO InstallNET.sh 'https://unixetc.com/res/InstallNET.sh'
## 添加执行权限
chmod a+x InstallNET.sh
## 通过脚本安装网络镜像，这个过程时间可能较长，因为要下载fnos.vhd.gz镜像文件。
./InstallNET.sh --image 'https://r2.yx.lu/fnos.vhd.gz'

     Add DNS Record for Public IP
---------------------------------------

  From your DNS provider's control panel, create the required
  DNS record with the value of your server's public IP address.

  + Any DNS name that can be resolved on the public internet will work.
  + Replace example.com below with any valid domain name you control.
  + A TTL of 600 seconds (10 minutes) is recommended.

  Example DNS record:

    NAME                TYPE   VALUE
    ----                ----   -----
    example.com         A      195.192.118.6
    *.example.com       A      195.192.118.6

  **IMPORTANT**
  It's recommended to wait 3-5 minutes after creating a new DNS record
  before attempting to use it. This will allow time for the DNS record
  to be fully updated.

## 输入域名和管理员邮箱
Enter your public DNS address (e.g. example.com): pds.p9.pub
Enter an admin email address (e.g. [email protected]): [email protected]

$ hugo new site test
Congratulations! Your new Hugo site is created in D:\test.

Just a few more steps and you're ready to go:

1. Download a theme into the same-named folder.
   Choose a theme from https://themes.gohugo.io/ or
   create your own with the "hugo new theme <THEMENAME>" command.
2. Perhaps you want to add some content. You can add single files
   with "hugo new <SECTIONNAME>\<FILENAME>.<FORMAT>".
3. Start the built-in live server via "hugo server".

Visit https://gohugo.io/ for quickstart guide and full documentation.
