DNS简配

一、安装包

         bind-9.3......rpm

         bind-chroot-9.3......rpm

         bind-devel-9.3.......rpm

         caching-nameserver-9.3.....rpm

 

二、配置<只显示修改后的内容>

1.#vi /etc/reslov.conf

添加nameserver 192.168.1.100<本机IP作DNS服务器>

 

2.#vi /etc/sysconfig/network

修改HOSTNAME=linux.example.com<根据实际情况修改>

 

3.#vi /etc/hosts<可不做>

添加192.168.1.100      linux.example.com       linux

 

4.#vi /etc/named.rfc1912.zones

最下面添加zone

zone "example.com" IN {
        type master;
        file "example.com";
        allow-update { none; };
};

zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "named.1.168.192";
        allow-update { none; };
};

 

5.#vi /etc/named.caching-nameserver.conf

把下列列出的改为

            listen-on port 53 { any; };
        listen-on-v6 port 53 { any; };                <支持ip V6用>

        allow-query     { any; };
        allow-query-cache { any; };

        match-clients      { any; };
        match-destinations { any; };

 

6.#cd /var/named/chroot/var/named/

   #cp named.local    named.1.168.192   

   #cp named.zero    example.com

<这两个文件名需与named.rfc1912.zones 中指定的相同>

 

7.#vi  named.1.168.192

修改为

$TTL    86400
@       IN      SOA     localhost. root.localhost.  (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
@        IN      NS       linux.example.com.
100      IN      PTR     linux.example.com.
@        IN      MX   5  mail.example.com.
100      IN      PTR     mail.example.com.
100      IN      PTR     www.example.com .

 

   #vi  example.com

修改为

$TTL    86400
@               IN SOA  localhost.      root.localhost. (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
@       IN      NS      linux.example.com.
linux.example.com.    IN      A       192.168.1.100
@       IN      MX   5  mail.example.com.
mail     IN      A        192.168.1.100
www     IN      A       192.168.1.100

 

注意一下几点：

①.上面两个配置文件出现的网址后面必须以“.”结尾

②.named.1.168.192与example.com所属组必须为named
