Centos 远程重装系统脚本
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 # http://babyfenei.blog.51cto.com/443861/1775441 # 2016年5月20日 # # # Fenei QQ:407603129 Mail：[email protected] # VER. 1.1.0 - http://www.fenei.net # #===================================================================== stty erase ^h stty erase ^H while true do printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + +\n" printf " + 请输入服务器IP地址 +\n" printf " + ※注意：此IP地址用作VNC远程连接使用※ +\n" printf " + ※ 同时,此IP为重装后系统默认IP※ +\n" printf " + ※ 建议输入您将要配置的IP地址 ※ +\n" printf " + eg：192.168.1.10 124.115.146.254 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read IPADDRESS clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + +\n" printf " + 请输入服务器子网掩码 +\n" printf " + eg：255.255.255.0 255.255.255.248 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read NETMASK clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + +\n" printf " + 请输入服务器网关地址 +\n" printf " + eg：192.168.1.1 255.255.255.248 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read GATEWAY clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + +\n" printf " + 请输入服务器DNS地址 +\n" printf " + eg：180.76.76.76 114.114.114.114 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read DNS clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + +\n" printf " + 请输入VNC远程密码 +\n" printf " + eg：admin Admin#@!1234567 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read PASSWD clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " + 您的服务器IP配置信息为 +\n" printf " + IP地址: $IPADDRESS 子网掩码：$NETMASK +\n" printf " + 网关 ：$GATEWAY DNS : $DNS +\n" printf " + 请确保配置信息正确，否则将无法远程登录 +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read anykey clear printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " ++++++++++++请选择需要安装的Centos系统版本++++++++++++++++\n" printf " + +\n" printf " + 1.CentOS 6.1-X86_64 +\n" printf " + 2.CentOS 6.2-X86_64 +\n" printf " + 3.CentOS 6.3-X86_64 +\n" printf " + 4.CentOS 6.4-X86_64 +\n" printf " + 5.CentOS 6.5-X86_64 +\n" printf " + 6.CentOS 6.6-X86_64 +\n" printf " + 7.CentOS 6.7-X86_64 +\n" printf " + 8.CentOS 7.0-X86_64 +\n" printf " + +\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" printf " ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\n" read selec case "$selec" in "1") ##### CentOS 6.1-X86_64 ##### mkdir /centos_install cd /centos_install wget http://服务器IP地址/XP/linux/centos/x86_64/6.1/images/pxeboot/initrd.img wget http://服务器IP地址/XP/linux/centos/x86_64/6.1/images/pxeboot/vmlinuz cp vmlinuz /boot/vmlinuz.cent.pxe cp initrd.img /boot/initrd.img.cent.pxe #在"hiddenmenu" 和 "title CentOS..." 增加一项: #method中的url为安装centos的源 sed -i -e "/hiddenmenu/a\title CentOS 6.1-X86_64 Install (PXE)\nroot (hd0,0) \nkernel \/vmlinuz.cent.pxe vnc vncpassword=${PASSWD} headless ip=${IPADDRESS} IP netmask=${NETMASK} gateway=${GATEWAY} dns=${DNS} ksdevice=eth0 method=http:\/\/服务器IP地址\/XP\/linux\/centos\/x86_64\/6.1\/ lang=en_US keymap=us\ninitrd \/initrd.img.cent.pxe" /boot/grub/grub.conf ;;

4、运行结束后检查运行结果
less /boot/grub/grub.conf
ll /boot/
验证成功后重启服务器进行安装
至此安装完成
