DNS设定实例
环境:
redhat9 :默认集成bind-9.2.1-16
功能:
内部使用的DNS,也可以访问外网的域名.
需求:
实验就将192.168.0.111作为dns服务器,192.168.0.28作为客户端
配置文件如下
/etc/named.conf
// 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;
forwarders {
202.103.24.68;
};
pid-file "/var/run/named/named.pid";
};
//使得外部域名向外转发到202.103.24.68查询(武汉电信的DNS)
//
// 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 "domain1.com" IN {
type master;
file "domain1.com.zone";
allow-update { none; };
};
zone "domain2.com" IN {
type master;
file "domain2.com.zone";
allow-update { none; };
};
zone "0.168.192.in-addr.arpa" IN {
type master;
file "0.168.192.local";
allow-update { none; };
};
include "/etc/rndc.key";
/var/named/domain1.com.zone
$TTL 86400
$ORIGIN domain1.com.
@ 1D IN SOA localhost. root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS localhost.
s1 1D IN A 192.168.0.111
s2 1D IN A 192.168.0.111
/var/named/domain2.com.zone
$TTL 86400
$ORIGIN domain2.com.
@ 1D IN SOA localhost. root (
42 ; serial (d.
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS localhost.
s3 1D IN A 192.168.0.111
s4 1D IN A 192.168.0.28
/var/named/0.168.192.local
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
111 IN PTR s1.domain1.com.
111 IN PTR s2.domain1.com.
111 IN PTR s3.domain2.com.
28 IN PTR s4.domain2.com.
启动服务
/etc/rc.d/init.d/named start
port 观察：
[root@test root]# netstat -tuln | grep 53 查看日志
tail -n 15 /var/log/messages | grep named
在设定好之后,方便直接在dns服务器调试,需要改本机的DNS,可以这么改
[root@localhost named]# vi /etc/resolv.conf
nameserver 127.0.0.1
nameserver 202.103.24.68
search localdomain
客户端测试,在XP上将DNS指向192.168.0.111
ping如下地址
s1.domain1.com
s2.domain1.com
s3.domain2.com
s4.domain2.com
所有通过表示成功
