Linux安装DNS主要要安装2个程序：
[root@tiejiang ~]# yum install bind* //linux下 用于解析DNS的程序 [root@tiejiang ~]# yum install caching-nameserver //这是另外一个软件
安装完成后，会发现/VAR/NAMED/下多出了几个文件。证明安装好了。
[root@tiejiang ~]# vim /etc/named.caching-nameserver.conf //以下为完整配置后的配置文件内容
// Provided by Red Hat caching-nameserver package to configure the
// ISC BIND named(8) DNS server as a caching only nameserver
// (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
// DO NOT EDIT THIS FILE - use system-config-bind or an editor
// to create named.conf - edits to this file will be lost on
// caching-nameserver package upgrade.
//
