Red Hat Enterprise Linux AS3 中dns server的配置－－字符界面
Red Hat Enterprise Linux AS3 中dns server的配置－－字符界面
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/supermaster.com.zone---------系统没有，需要创建配置
/var/named/0.168.192.in-arpa.zone--------系统没有，需要创建配置
/var/named/named.local------------------------系统自带，不需修改
/var/named/named.ca--------------------------系统自带，不需修改
2.配置方案
2.1、/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。源文件如下：
## named.conf - configuration for bind
#
# Generated automatically by redhat-config-bind, alchemist et al.
# Any changes not supported by redhat-config-bind should be put
# in /etc/named.custom
#
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
include "/etc/named.custom";
include "/etc/rndc.key";
zone "0.0.127.in-addr.arpa" {
type master;
file "0.0.127.in-addr.arpa.zone";
};
zone "0.168.192.in-addr.arpa" {
type master;
file "0.168.192.in-addr.arpa.zone";
};
zone "localhost" {
type master;
file "localhost.zone";
};
zone "supermaster.com" {
type master;
file "supermaster.com.zone";
};
2.2、/var/named/supermaster.com.zone
说明：正向解析配置文件，即实现name2ip的对应，源文件如下：
$TTL 86400
@ IN SOA dns.supermaster.com. root.localhost (
2 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)
IN NS dns.
mail IN MX 1 mail
dns IN A 192.168.0.100
www IN A 192.168.0.100
ftp IN A 192.168.0.100
mail IN A 192.168.0.100
2.3、/var/named/0.168.192.in-arpa.zone
说明：DNS反向解析配置文件，即实现IP2name的对应，源文件如下：
$TTL 86400
@ IN SOA dns.supermaster.com. root.localhost (
7 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttk
)
@ IN NS dns.
@ IN NS ftp.
@ IN NS mail.
@ IN NS www.
100 IN PTR redhat.supermaster.com.
2.4、/etc/resolv.conf
说明：指定域名服务器的IP和搜索顺序，源文件如下：
search supermaster.com
nameserver 192.168.0.100
3.测试及管理办法
3.1、修改完DNS的配置文件，需要重新启动named，输入：named -u named
来使更改的配置生效
3.2、nslookup测试正向解析、反向解析是否正常。如下：
A：正向解析
[root@redhat root]# redhat-config-bind
[root@redhat root]# nslookup -sil www.supermaster.com
Server: 192.168.0.100
Address: 192.168.0.100#53
Name: www.supermaster.com
Address: 192.168.0.100
B：反向解析
[root@redhat root]# nslookup -sil 192.168.0.100
Server: 192.168.0.100
Address: 192.168.0.100#53
100.0.168.192.in-addr.arpa name = redhat.supermaster.com.
到此DNS服务器已经正确设置了，大家可以看到53端口已经在运行了
[root@redhat root]#netstat –nl
