1、试验环境1. 装有 RHEL5 系统计算机一台； server:192.168.1.102 2. 客户机一台； pc:192.168.1.252 3. 两主机课通信；实验目的1.dns 服务器包的安装；2. 正向区域和反向区域的建立；3. 正向和反向的测试；实验步骤：第一步：安装 dns 服务器包；roothuyb #mount /dev/cdrom /mnt/mount roothuyb #cd /mnt/Server roothuyb Server# rpm -ivh bind-9.3.3-7.el5.i386.rpm roothuyb Server# rpm -ivh bind-chro

2、ot-9.3.3-7.el5.i386.rpm roothuyb Server# rpm -ivh caching-nameserver-9.3.3-7.el5.i386.rpm 第二步：建立主配置文件，并修改相关选项；roothuyb #cd /var/named/chroot/etc roothuyb etc#cp -p named.caching-nameserver.conf named.conf roothuyb etc#vi named.conf . . options listen-on port 53 any; ; /侦听接口； listen-on-v6 port 53 :1;
