Centos 远程重装系统脚本

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Centos 远程重装系统脚本相关的知识，希望对你有一定的参考价值。

因公司有些服务器需要经常重装系统，每次跑机房比较麻烦，特做此脚本进行远程安装

目前因Http服务器空间有限，只左右Centos6.1-7.0 64位系统的远程安装

如需增加  只需按照以前的步骤和方法添加即可。

1、http服务器的搭建

我这里使用IIS作为http服务器（linux下最好）

启用IIS目录浏览功能，并在http头标签页的MIME类型 中添加相应的MIME类型，方便下载此目录下所有文件。

新建MIME类型，在拓展名和MIME类型中都填*

确定保存。

2、解压镜像文件到http服务器

3、在需要重装系统的服务器上运行一下脚本

   使用您自己的http服务器地址替换脚本中的IP地址

#!/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
