15、DNS视图 学习笔记

view 视图,逻辑的DNS服务器,不一样的请求有意返回不一样的值


目标:120段解析返回120段的IP,其他解析返回130段IP


1、安装bind

[root@localhost ~]# yum -y install bind


2、配置主配置文件

[root@localhost ~]# sed "/^\//d" /etc/named.conf


options {

        directory       "/var/named";

        dump-file       "/var/named/data/cache_dump.db";

        statistics-file "/var/named/data/named_stats.txt";

        memstatistics-file "/var/named/data/named_mem_stats.txt";

        allow-query     { 192.168.0.0/16; };

        recursion yes;



        /* Path to ISC DLV key */


};


logging {

        channel default_debug {

                file "data/named.run";

                severity dynamic;

        };

};



include "/etc/named.rfc1912.zones";


3、配置区域数据文件

[root@localhost ~]# sed "/^\//d" /etc/named.rfc1912.zones


view net120 {

        match-clients { 192.168.120.0/24; };


        zone "." IN {

                type hint;

                file "named.ca";

        };


        zone "localhost.localdomain" IN {

                type master;

                file "named.localhost";

                allow-update { none; };

        };


        zone "localhost" IN {

                type master;

                file "named.localhost";

                allow-update { none; };

        };


        zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {

                type master;

                file "named.loopback";

                allow-update { none; };

        };


        zone "1.0.0.127.in-addr.arpa" IN {

                type master;

                file "named.loopback";

                allow-update { none; };

        };


        zone "0.in-addr.arpa" IN {

                type master;

                file "named.empty";

                allow-update { none; };

        };


        zone "kaiyuandiantang.com" IN {

                type master;

                file "kaiyuandiantang.com.net120";

        };


};


view net130 {

        match-clients { any; };

        zone "kaiyuandiantang.com" IN {

                type master;

                file "kaiyuandiantang.com.net130";

        };

};


[root@localhost ~]# 


4、配置数据库文件

[root@localhost named]# cat kaiyuandiantang.com.net120 

$TTL 600

@       IN      SOA     ns1.kaiyuandiantang.com.        admin.kaiyuandiantang.com. (

                        2017090801

                        1H

                        5M

                        3D

                        12H

                        )

        IN      NS      ns1

        IN      MX  10  mail

ns1     IN      A       192.168.130.120

mail    IN      A       192.168.120.10

www     IN      A       192.168.120.20

[root@localhost named]# 

[root@localhost named]# cat kaiyuandiantang.com.net130  

$TTL 600

@       IN      SOA     ns1.kaiyuandiantang.com.        admin.kaiyuandiantang.com. (

                        2017090801

                        1H

                        5M

                        3D

                        12H

                        )

        IN      NS      ns1

        IN      MX  10  mail

ns1     IN      A       192.168.130.120

mail    IN      A       192.168.130.10

www     IN      A       192.168.130.20

[root@localhost named]# 


5、修改权限启动服务

[root@localhost named]# chown root:named kaiyuandiantang.com.net1*

[root@localhost named]# chmod 640 kaiyuandiantang.com.net1*

[root@localhost named]# named-checkconf 

[root@localhost named]# named-checkzone kaiyuandiantang.com kaiyuandiantang.com.net120 

zone kaiyuandiantang.com/IN: loaded serial 2017090801

OK

[root@localhost named]# named-checkzone kaiyuandiantang.com kaiyuandiantang.com.net130  

zone kaiyuandiantang.com/IN: loaded serial 2017090801

OK

[root@localhost named]# service named start

Generating /etc/rndc.key:                                  [  OK  ]

Starting named:                                            [  OK  ]

[root@localhost named]# tail /var/log/messages

Sep  8 16:41:44 localhost named[3202]: zone 0.in-addr.arpa/IN/net120: loaded serial 0

Sep  8 16:41:44 localhost named[3202]: managed-keys-zone ./IN/net120: loaded serial 0

[root@localhost named]#
