在这里,服务器主机(FC4)IP为192.168.23.1,局域网内有若干XP主机.配置要求为XP主机192.168.23.2分配 kvew.secodernet.com ,然后www.secodernet.com访问主机
首先修改/etc/named.conf配置文件,添加如下信息,特别注意格式.相关配置项的具体含义就不讲了,可参考HOWTO文档
//======================================
// named.conf中的添加信息
//======================================
zone "secodernet.com" IN {
type master;
file "zone.test";
allow-update { none; };
};
zone "23.168.192.in-addr.arpa" IN {
type master;
file "zone.test.rev";
allow-update { none; };
};
//======================================
从上面的配置中我们可以看出,每个配置都有一个相应的配置文件.这里我们将在/var/named目录下创建zone.test 和 zone.test.rev两个配置文件. 内容如下
//=====================================
// zone.test
//=====================================
$TTL 86400
@ IN SOA kvew.secodernet.com. root.secodernet.com. (
2006052000;
3600 ;
900 ;
3600000 ;
3600 ) ;
IN NS kvew.secodernet.com.
;
kvew IN A 192.168.23.2
www IN A 192.168.23.1
//======================================
下面是zone.test.rev配置文件,特别注意格式
//====================================
// zone.test.rev
//====================================
$TTL 86400
@ IN SOA kvew.secodernet.com. root.secodernet.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
;
IN NS kvew.secodernet.com.
2 IN PTR kvew.secodernet.com.
1 IN PTR www.secodernet.com.
//=====================================
下面开启named服务进程
[root@localhost ~]# service named start
启动 named： [ 确定 ]
如果看到以上信息,那么就成功了,要是无法开启,那么查看/var/log/message文件,并作相应的修改
然后用nslookup来测试下
[root@localhost ~]# nslookup

一切正常了,OK,到此结束,就这么简单. :)
如果启动的时候出现错误,那么多半是配置格式出了错,比如掉了'.' 或者是IN前面的空格,一般IN前空出一个TAB, 然后IN前面的www和kvew要顶格
最后如果出现本地可以正常解析而其他机器上无法解析,那么检查下其他机器是否将首DNS服务器(这里是192.168.23.1)设置为了你的服务器主机.再不行的话,就看看自己的主机防火墙设置,是否禁止访问53端口.同样其他的服务配置的时候也要注意这个问题,比如Apache的配置,看看是否禁止了80端口,然后可运用IPtables进行相应修改. ]]>
