虚拟机克隆完后，通常我使用这两个脚本来帮助快速部署，一个是修改主机名，一个是修改IP地址(IP地址修改比较适合只用一块网卡的虚拟机，修改eth0的IP地址)。适合Redhat 6及CentOS 6的操作系统。修改主机名：#!/bin/bash# Ivan Liao - Version 0.1clear# ---- prompt for new hostname, current hostname is default ----oldName=`hostname -s`read -p "Enter new Hostname, do not enter DNS suffix [$oldName]: " newName# ---- confirm change ----read -p "Change hostname to $newName? [ y or n ]: " okcase $ok in[Yy]*) echo "Start to change hostname..." ;;[Nn]*) echo exiting without changes exit 1 ;;esac# ---- make changes to /etc/hosts ----# If it is a softlink, this will change it into a real file[ ! -h /etc/hosts ] && perl -i -p -e "s/$oldName/$newName/g" /etc/hosts# ---- make changes to /etc/sysconfig/network ----[ ! -h /etc/hosts ] && perl -i -p -e "s/$oldName/$newName/g" /etc/sysconfig/network[ ! -h /etc/hosts ] && perl -i -p -e "s/.localdomain//g" /etc/sysconfig/network# ---- make changes to /etc/sysconfig/network-scripts files ----for hostsFile in `find /etc/sysconfig/network-scripts -type f -print`do perl -i -p -e "s/$oldName/$newName/g" $hostsFiledone# ---- move or create /var/crash directory ----if [ -d /var/crash/$oldName ]; then mv /var/crash/$oldName /var/crash/$newNameelse mkdir /var/crash/$newName chmod 700 /var/crash/$newNamefi# ---- finally, change hostname ----hostname $newName# ---- confirm changes ----echo -n "Hostname has been changed to: "hostnameecho ""#echo -n "Now FQDN is: "#hostname -f修改IP地址：#!/bin/bash# Ivan Liao - Version 0.1clearrm -f /etc/sysconfig/network-scripts/ifcfg-eth0rm -f /etc/sysconfig/networking/devices/ifcfg-eth0 rm -f /etc/sysconfig/networking/profiles/default/ifcfg-eth0 macaddress=`ifconfig -a|grep eth1|awk '{print $NF}'`[ ! -h /etc/udev/rules.d/70-persistent-net.rules ] && perl -i -p -e "s/SUBSYSTEM.*eth0"//g" /etc/udev/rules.d/70-persistent-net.rules[ ! -h /etc/udev/rules.d/70-persistent-net.rules ] && perl -i -p -e "s/eth1/eth0/g" /etc/udev/rules.d/70-persistent-net.rulesread -p "Enter new IP address: " ipaddress# ---- confirm change ----read -p "Change IP address to $ipaddress?
