这是一篇实践性的文章，如果你还不知道DNS是个什么东西和bind的一些简单知识建议还是了解一下先
首先，确认系统是否装有bind
# rpm -qa|grep bind
我用的就是redhatas4u3自带的bind：bind-9.2.4-2这个版本（如果没有bind的话 就去下载一个源码包吧，具体怎么安装就不在说了 这样的文档google一下，一大把）
如果是系统自带的bind是安装在/var/named/chroot下的（chroot如果不知道的话 也去google一下吧）
下面是具体操作:
# cd /var/named/chroot/etc/ //进入chroot环境下的etc目录
(建议在编辑配置文件之前先备份一下已有的配置文件！！！)
# vi named.conf //编辑bind的主配置文件
//
// named.conf for Red Hat caching-nameserver
//
options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
