因公司centos服务器重装需求较多,且服务器没有远控卡,每次重装系统需要到机房操作,费时费力.特作此脚本.
此脚本适用于Centos6.1-Centos7.3 64系统的远程安装.如需其他版本请自行添加!
运行脚本如下:
使用VNC进行远程重装操作!
脚本如下:
#!/bin/bash
# Centos AutoInstall
# VER. 1.1.0 - http://www.fenei.net
# 此脚本主要为方便远程重装centos系统使用，目前因空间问题只做到6.1-7.0的64位版本
# 此脚本需要搭建一套http服务器并启用目录浏览，将需要远程安装的镜像解压到http服务器
# 脚本运行完成以后需要使用vnc客户端连接服务器进行安装.重装系统的服务器需和VNC客户端互通
#
# 2016年5月20日3
# VER. 2.1.0 - http://www.fenei.net
# 更改自动获取服务器IP地址.
# 新增镜像站点网络连接判断
# 新增centos7系列grub2的安装
#
# 2017年4月24日
