dns的主从服务器的简单配置

主服务器配置：

1.在/etc/named.rfc1912.zones里写入如下内容：

zone "neo.com" IN {

type master;

file "neo.zone";

allow-transfer { 10.3.156.134; }; --> slave从服务器的地址

};

zone "156.3.10.in-addr.arpa" IN {

type master;

file "10.3.156.zone";

allow-transfer { 10.3.156.134; };

};

2.在/var/named下新建neo.zone文件：并写入如下内容：

$TTL 86400

@ IN SOA dns.neo.com. root.neo.com. (

20130110801 ; serial

1D ; refresh

1H ; retry

1W ; expire

3H ) ; minimum

@ IN NS dns.neo.com.

IN NS ns2.neo.com.

dns.neo.com. IN A 10.3.156.130

www.neo.com. IN A 10.3.156.130

mail.neo.com. IN A 10.3.156.130

ns2 IN A 10.3.156.134

新建10.3.156.zone文件,写入如下内容：

$TTL 86400

@ IN SOA dns.neo.com. root.neo.com. (

2013110801

2H

10M

7D

6H )

@ IN NS dns.neo.com.

IN NS ns2.neo.com.

130 IN PTR dns.neo.com.

130 IN PTR www.neo.com.

130 IN PTR mail.neo.com.

134 IN PTR ns2.neo.com.

3.从服务器配置：在/etc/rfc1912,zones里写入如下内容：

zone "neo.com" IN {

type slave;

file "slaves/neo.zone";

masters { 10.3.156.130; };

};

zone "156.3.10.in-addr.arpa" IN {

type slave;

file "slaves/10.3.156.zone";

masters { 10.3.156.130; };

};
