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系统远程重装脚本相关的知识，希望对你有一定的参考价值。
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 # # # [email protected] Sinpul Network # http://www.fenei.net # #===================================================================== # 获取本机IP及版本信息 IPADDRESS=$(ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk ‘{print $2}‘|tr -d "addr:") NETMASK=$(ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk ‘{print $4}‘|tr -d "Mask:") GATEWAY=$(ip route |grep default|awk ‘{print $3}‘) DNS=$(cat /etc/resolv.conf | awk ‘NR>1‘ |awk ‘{print $2}‘ | head -n 1) RELEASE=$(rpm -q centos-release | cut -d ‘-‘ -f 3) stty erase ^h stty erase ^H stty erase ^? #将shell运行过程中读取退格键 替换为退格命令，否则会输出 ^H！^? host=192.168.1.11 ping -c2 $host >>/dev/null if [ $? -eq 0 ];then echo “Mirrors network is ok,wait to install ...” ping -c5 $host >>/dev/null if [ "$RELEASE" = "6" ];
