一键脚本: Debian(Ubuntu)网络安装/重装

全文转载自Vicer的博客:萌咖
用途:无法通过后台面板重装系统的时候,人工在SSH或VNC界面重装。

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.

准备

  • Debian/Ubuntu/CentOS 系统(由GRUB引导);
  • wget 用来下载文件,获取公网IP;
  • ip 获取网关,掩码等;
  • sed awk grep 处理文本流;
  • 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

一键安装

使用方法

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]

安装实例

  • 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

具体案例

  • 【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 32
  • 安装Debian 9 x64:
bash DebianNET.sh -d stretch -v amd64

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

注意事项

  • 在安装Ubuntu时,可能会遇到:
    Getting the time form a network time server...
    界面进度条很长时间不会动,可以等待它超时或者更换别的版本.
    该问题是Ubuntu系统的问题.
