操作系统版本centos 5.5需要安装一些软件，使用以下命令既可
#yum -y install bind*
#yum -y install caching-nameserver
这个是做备份文件，（连权限一起复制-p）
#cd /var/named/chroot/etc
#cp -p named.caching-nameserver.conf named.conf
下面开始进行配置，把所有代表本地的：127.0.0.1,localhost，都改成any，表示监听所有主机的请求
#vi named.caching-nameserver.conf
示例：

启动服务
#/etc/init.d/named start
设置服务自动启动
#chkconfig --level 35 named on
如果要开启防火墙，请输入以下指令
#iptables -A INPUT -p udp --dport 53 -j ACCEPT
#iptables -A INPUT -p tcp --dport 53 -j ACCEPT
这样就可以用该主机做DNS服务器了。
match-clients { any; };
match-destinations { any; };
说是这两个可以不改，不过我没试，以后再试吧
----------------------------------------------------------------------------------------------------------------------------------------------------
要设置本地的DNS解析
cd /var/named/chroot/etc
vi named.caching-nameserver.conf
在最后加上
zone "test.com" IN { //这里就是你要的服务器名的域名，主机名在后面的一个文件里设置
type master;
file "test.com.zone";
allow-update { none; };
};
// 反向解释，这个我没做，非必需，以后试
zone "1.168.192.in-addr.arpa" IN {
type master;
file "1.168.192.in-addr.arpa.zone";
};
还有要做的是
/*view localhost_resolver {
match-clients { localhost; };
match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};*/
此处要将view字段注释掉，否则在文件末尾添加zone字段后，启动named服务时，会报如下错误：“/etc/named.conf:47: when using 'view' statements, all zones must be in views”，但view还是很有用的，网上查资料所得，它可以是的bind将一个域名对应几个不同的IP地址。
# cd /var/named/chroot/var/named/
# cp –p localdomain.zone xxt401.com.zone(cp -p localhost.zone it.com.zone)
# cp –p named.local 1.168.192.in-addr.arpa.zone
# vi xxt401.com.zone(vi it.com.zone)
最后一行增加
bbs IN A 10.8.12.112
然后重起一下named ,然后bbs.it.com就可以被解析了
