DNS（续）

view

    首先我们先定义配置文件：

#vi /etc/named.conf

acl "innet" { 192.168.0/24; };

acl "exnet" { 192.168.10/24; };

options {

          directory "/var/named";

        };

 

view "internal" {

match-clients { innet; };

recursion yes;

 

zone "." IN {

                type hint;

                file "named.ca";

            };

zone "localhost" IN {

                        type master;

                        file "localhost.zone";

                    };

zone "0.0.127.in-addr.arpa" IN {

                                   type master;

                                   file "named.local";

                                };

zone "example.com" IN {

                         type master;

                         file "example.com.in";

                      };

};

 

view "external" {

match-clients { any; };

recursion no;

 

 

zone "." IN {

                type hint;

                file "named.ca";

            };

zone "example.com" IN {

                        type master;

                        file "example.com.ex";

                      };

};

 

然后开始定义下面这几个区域文件： named.ca ， localhost.zone ， named.local ， example.com.in ， example.com.ex ；

这几个区域文件须在目录 /var/named 下做：

#cd /var/named

#dig -t NS . > named.ca

#vi localhost.zone

$TTL    1D

@       1D      IN      SOA     localhost.      root.localhost. (

                                                                2010080301

                                                                3M

                                                                1M

                                                                7D

                                                                1D )

@       IN      NS      localhost.

localhost.      IN      A       127.0.0.1

 

#vi named.local

$TTL    1D

@       1D      IN      SOA     localhost.      root.localhost. (

                                                                2010080301

                                                                3M

                                                                1M

                                                                7D

                                                                1D )

@       IN      NS      localhost.

1.0.0.127.in-addr.arpa.         IN      PTR     localhost.

 

#vi example.com.in

$TTL 1D

$ORIGIN  example.com.

@       86400   IN      SOA     ns.example.com.         root.example.com. (

                                                                           2010080301

                                                                           3M

                                                                           1M

                                                                           7D

                                                                           1D )

        IN      NS      ns

        IN      MX      10 mail1

ns      IN      A       192.168.0.54

mail1   IN      A       192.168.0.55

www     IN      A       192.168.0.57

 

#vi example.com.ex

$TTL 1D

$ORIGIN  example.com.

@       86400   IN      SOA     ns.example.com.         root.example.com. (

                                                                           2010080301

                                                                           3M

                                                                           1M

                                                                           7D

                                                                           1D )

        IN      NS      ns

        IN      MX      20 mail2

ns      IN      A       192.168.10.18

mail2   IN      A       192.168.10.56

ftp     IN      A       192.168.10.57

 

这样就把这几个区域文件配置完成了，但是我们还需把这几个区域文件改权限：

#chgrp named named.ca ， localhost.zone ， named.local ， example.com.in ， example.com.ex

下面来测试下语法是否正确：

#service named configtest

下面来启动 :

#service namde restart

下面我们就可以用 192.168.0/24 和 192.168.10/24 这两个网段来测试

用 host 和 dig 来测试。
