该脚本在 MoeClub 与 hiCasper 的脚本基础上优化，实现了一键网络重装 CentOS / Debian / Ubuntu 系统及DD方式安装系统。解决了云服务商提供模板镜像体积过大、预装软件过多、不够纯净等问题。
使用方法
#下载 wget http://mirror.apad.pro/autoreinstall/AutoReinstall.sh #执行 bash AutoReinstall.sh #重装后 #CentOS7密码为Pwd@CentOS #其它系统密码为Pwd@Linux #请修改密码 sudo passwd
支持重装的系统
CentOS 7.7 (DD Image) CentOS 7.6 (ServerSpeeder Avaliable) CentOS 6 Debian 9 Debian 10 Ubuntu 16.04 Ubuntu 18.04 Custom image (自定义DD镜像)
系统说明
·自动获取IP地址、网关、子网掩码 ·自动判断网络环境，选择国内/外镜像，解决速度慢的问题 ·脚本代码开源，无安全隐患 ·CentOS 7 镜像抛弃LVM，回归ext4，减少不稳定因素 ·OpenVZ / LXC 架构系统不适用
