Centos系统远程重装脚本

CentOS 前端之家
前端之家收集整理的这篇文章主要介绍了Centos系统远程重装脚本，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

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

#CentosAutoInstall
#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
