在查阅许多DNS配置手册后,无法是照办还是修改，我始终没有配置正确,总是正向解析无法解析.最后,在一次配置中,突然灵机一动,终于配置成功。
下面是我配置DNS的实例:
1 所需配置文件:
/etc/named.conf 系统自带，需要配置
/etc/resolv.conf 系统自带，需要配置
/var/named/myqmail.com.db 系统没有，自已创建
/var/named/db.192.168.0.198 系统没有，自已创建
/var/named/named.local 系统自带，不需要修改
/var/named/named.ca 系统自带，不需要修改
2 相关工具
nslookup
说明：检测DNS是否配置正确的工具，系统自带。
3 配置方案
3.1 /etc/named.conf
说明：DNS主配置文件，定义了域数据库信息的基本参数和源点，该文件可以存放在本地或远程的服务器上。源文件：
// generated by named-bootconf.pl
options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "myqmail.com" IN {
type master;
file "myqmail.com.db";
allow-update { none;};
};
zone "0.168.192.in-addr.arpa" IN{
type master;
file "db.192.168.0.198";
allow-update { none;};
};
include "/etc/rndc.key";
