Debian(Ubuntu)系列重装系统一键脚本

我们使用VPS或服务器的时候有些商家提供的系统模板比较老旧或者自带了一些监控工具,如果你想重装为原版的纯净系统可以考虑萌咖博主提供的一键重装脚本。支持由GRUB引导的CentOS,Ubuntu,Debian一系列系统,本人测试了非常好用,重装系统只需几分钟。

    • 背景:

适用于由GRUB引导的CentOS,Ubuntu,Debian系统.
使用官方发行版去掉模板预装的软件.
同时也可以解决内核版本与软件不兼容的问题。
只要有root权限,还您一个纯净的系统。


    • 注意:

全自动安装默认root密码:Vicer,安装完成后请立即更改密码.
请使用 passwd root 命令更改密码.
特别注意:OpenVZ构架不适用.


    • 更新:
      • [2017.08.06]

增加支持重装为Ubuntu系统
支持列表:

本号  版本代号  VNC模式 自动模式
12.04  precise  yes     yes
14.04  trusty   yes     yes
15.10  wily     yes     yes
16.04  xenial   yes     yes
16.10  yakkety  yes     yes
17.04  zesty    yes     yes

安装Ubuntu时,必须使用版本代号.
如有必要,请使用--mirror自行更换软件源.
使用方法示例:

      • 以自动模式安装Ubuntu 16.04 64位为例:

bash DebianNET.sh -d xenial -v 64 -a


    • 需要:

1.Debian/Ubuntu/CentOS 系统(由GRUB引导);
2.wget 用来下载文件,获取公网IP;
3.ip 获取网关,掩码等;
4.sed awk grep 处理文本流;
5.VNC 安装系统(此项为可选)。


  • 确保安装了所需软件:
#Debian/Ubuntu:
apt-get install -y gawk sed grep
 
#RedHat/CentOS:
yum install -y gawk sed grep
  • 如果出现了错误,请运行:
#Debian/Ubuntu:
apt-get update
 
#RedHat/CentOS:
yum update

  • 一键下载及使用:
wget --no-check-certificate -qO DebianNET.sh 'https://moeclub.org/attachment/LinuxShell/DebianNET.sh' && chmod -x DebianNET.sh
Usage:
        bash DebianNET.sh       -d/--debian [7/wheezy|8/jessie|9/stretch]
                                -v/--ver [32/i386|64/amd64]

  • 安装示例:
    • 全自动安装:
bash DebianNET.sh -d wheezy -v i386 -a
  • VNC手动安装:
bash DebianNET.sh -d wheezy -v i386 -m

  • 使用:
    • 【默认】安装Debian 7 x32:
bash DebianNET.sh -d wheezy -v i386

-或者

bash DebianNET.sh -d 7 -v 32

  • 安装Debian 7 x64:
bash DebianNET.sh -d wheezy -v amd64

-或者

bash DebianNET.sh -d 7 -v 64

  • 安装Debian 8 x32:
bash DebianNET.sh -d jessie -v i386

-或者

bash DebianNET.sh -d 8 -v 32

  • 安装Debian 8 x64:
bash DebianNET.sh -d jessie -v amd64

-或者

bash DebianNET.sh -d 8 -v 64

  • 安装Debian 9 x32:
bash DebianNET.sh -d stretch -v i386

-或者

bash DebianNET.sh -d 9 -v 64

  • 安装Ubuntu 14.04 x32:
bash DebianNET.sh -d trusty -v 32
  • 安装Ubuntu 14.04 x64:
bash DebianNET.sh -d trusty -v 64

  • 安装Ubuntu 16.04 x32:
bash DebianNET.sh -d xenial -v 32
  • 安装Ubuntu 16.04 x64:
bash DebianNET.sh -d xenial -v 64

  • 安装Ubuntu 17.04 x32:
bash DebianNET.sh -d zesty -v 32
  • 安装Ubuntu 17.04 x64:
bash DebianNET.sh -d zesty -v 64
