DNS服务器配置
导读 | DNS(Domain Name Server,域名服务器)是进行域名(domain name)和与之相对应的IP地址 (IP address)转换的服务器。DNS中保存了一张域名(domain name)和与之相对应的IP地址 (IP address)的表,以解析消息的域名。下面就由我给大家简单说一下DNS服务器的配置。 |
主文件配置
定义DNS主文件/etc/named.rfc1912.zones,在后面加入下面几行:
zone"supsun.com" IN{ type master; file "supsun.com.zone"; allow-update{none;}; }; zone "6.1.10.in-addr.arpa" IN{ type master; file "supsun.com.local"; allow-update{ none }; };
正向解析文件配置/strong>
[root@localhost named]# cat supsun.com.zone $ TTL 86400 @ IN SOA dns.supsun.com. root.supsun.com. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 84600) ; Minimum @ IN NS dns.supsun.com. dns IN A 10.1.6.250 @ IN MX 5 main.supsun.com. main IN A 10.1.6.250
反向解析文件配置
[root@localhost named]# cat supsun.com.local $ TTL 86400 @ IN SOA dns.supsun.com. root.supsun.com. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 84600) ; Minimum @ IN NS dns.supsun.com. 250 IN PTR dns.supsun.com. @ IN MX 5 main.supsun.com. 250 IN PTR main.supsun.com.
DNS/IP名称解析伺服器
[root@localhost ~]# cat /etc/resolv.conf nameserver 10.1.6.250 search supsun.com
