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
- 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)。
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。
