BIND 9 例子
目前我不打算介绍如何配置Bind,Windows DNS Server,主要是没有时间去写,以后我会加上.
我做过Bind 9做主DNS,windows DNS Server 做辅助DNS,让他们同步数据. 这样可以在WIN DNS看到域名信息，比较直观，也很方便。如果你有兴趣可以自己做试验
这里我只给出一个例子。首先配置/etc/resolv.conf文件
[root@linux src]# cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 202.96.128.68
nameserver 218.30.103.50
nameserver 202.106.169.100
[root@linux src]#
               
配置/etc/named.conf文件
[root@linux src]# cat /etc/named.conf
// generated by named-bootconf.pl
options {
        directory "/var/named";
        /*
         * 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; };
};
zone "." IN {
        type hint;
        file "named.ca";
};
zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
};
zone "example.net" IN {
        type master;
        file "example.net";
        allow-update { none; };
};
include "/etc/rndc.key";
               
创建文件/var/named/example.net
[root@linux src]# cat /var/named/example.net
@ IN SOA        example.net. root.example.net. (
                          200211131 ; serial, todays date + todays serial #
                          28800 ; refresh, seconds
                          7200 ; retry, seconds
                          3600000 ; expire, seconds
                          86400 ) ; minimum, seconds
        NS ns.example.net.
@       IN A         192.168.0.1
www     IN A         192.168.0.1
mail    IN A         192.168.0.1
@       MX 10 mail.example.net.
[root@linux src]#
               
重新启动BIND(DNS 服务器)
[root@linux src]# service named restart
Stopping named:
[root@linux src]#                                          [  OK  ]
