1、概述本文以Redhat6.5为基础，通过配置网络安装服务器，实现Redhat Linux的网络安装。主要用到的软件（服务）有DHCP,TFTP,NFS,Kickstart等。本文只列出具体步骤，不含原理说明。1. 基础配置1.1 更改IP地址rootlocalhost # vi /etc/sysconfig/network-scripts/ifcfg-eth0rootlocalhost # cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0HWADDR=08:00:27:53:44:fbTYPE=EthernetUUID=82af
