文章转载自 如有乐享 & 萌咖 & 狗仔小分队的博客。

特别注意: OpenVZ构架不适用，安装之前备份重要数据。

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。

运行要求

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)。
   

   
   

安装脚本

全自动安装默认 root 密码: Vicer,安装完成后请立即更改密码。

安装时间（Vultr 2.5刀机器 重装大概15分钟） root用户密码为 xiaofd.win

注意事项

确保安装了所需软件:

1 2 3 4 5 #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: 1 2 3 4 5 #Debian/Ubuntu: apt–get update #RedHat/CentOS: yum update

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.
