RHEL5.0 搭建DNS服务器
实验环境： VM 6.0 ,RHEL5.0, 本地YUM源
次环境是把MAIL ，WWW等服务器与DNS 服务器放在一起
-、先检查系统是安装了bind.rpm 与caching-nameserver.rpm包
[root@ser ~]# rpm -qa bind* caching-*
bind-chroot-9.3.3-7.el5
bind-libs-9.3.3-7.el5
bind-9.3.3-7.el5
bind-libbind-devel-9.3.3-7.el5
bind-utils-9.3.3-7.el5
bind-devel-9.3.3-7.el5
caching-nameserver-9.3.3-7.el5
bind-sdb-9.3.3-7.el5
[root@ser ~]#
若没有,就安装这些包
二、配置dns的正向和反向解析文件
[root@ser ~]# cd /var/named/chroot/etc/
[root@ser etc]# ll
total 24
-rw-r–r– 1 root root 165 Apr 29 19:42 localtime
-rw-r—– 1 root named 1100 Jan 17 2007 named.caching-nameserver.conf
-rw-r—– 1 root named 614 Apr 30 13:04 named.rfc1912.zones
-rw-r–r– 1 root named 113 Apr 29 03:36 rndc.key
[root@ser etc]# cp -p named-caching-nameserver.conf naemed.conf
[root@ser etc]# vi named.rfc1912.zones
// named.rfc1912.zones:
//
// Provided by Red Hat caching-nameserver package
//
// ISC BIND named zone configuration for zones recommended by
// RFC 1912 section 4.1 : localhost TLDs and address zones
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
zone “.” IN {
type hint;
file “named.ca”;
};
zone “wgk.com” IN {
type master;
file “wgk.com.zone”;
allow-update { none; };
};
zone “1.168.192.in-addr.arpa” IN {
type master;
file “wgk.com.local”;
allow-update {none;};
};
[root@ser etc]# vi named.conf
//
// named.caching-nameserver.conf
//
// Provided by Red Hat caching-nameserver package to configure the
// ISC BIND named(8) DNS server as a caching only nameserver
// (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
// DO NOT EDIT THIS FILE – use system-config-bind or an editor
// to create named.conf – edits to this file will be lost on
// caching-nameserver package upgrade.
//
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { ::1; };
directory “/var/named”;
dump-file “/var/named/data/cache_dump.db”;
statistics-file “/var/named/data/named_stats.txt”;
memstatistics-file “/var/named/data/named_mem_stats.txt”;
query-source port 53;
query-source-v6 port 53;
allow-query { any; };
};
logging {
channel default_debug {
file “data/named.run”;
severity dynamic;
};
};
view localhost_resolver {
match-clients { any; };
match-destinations { any; };
recursion yes;
include “/etc/named.rfc1912.zones”;
};
# 黄色为修改部分
[root@ser etc]#
[root@ser etc]# cd /var/named/chroot/var/named/
查看ll 如下：
drwxrwx— 2 named named 4096 Apr 30 13:21 data
-rw-r—– 1 root named 198 Jan 17 2007 localdomain.zone
-rw-r—– 1 root named 195 Jan 17 2007 localhost.zone
-rw-r—– 1 root named 427 Jan 17 2007 named.broadcast
-rw-r—– 1 root named 2518 Jan 17 2007 named.ca
-rw-r—– 1 root named 424 Jan 17 2007 named.ip6.local
-rw-r—– 1 root named 426 Jan 17 2007 named.local
-rw-r—– 1 root named 427 Jan 17 2007 named.zero
drwxrwx— 2 named named 4096 Jul 27 2004 slaves
[root@ser named]# cp -p localdomain.zone wgk.com.zone(一定要加-p参数，否则后面出错。)
[root@ser named]# cp -p named.local wgk.com.local
[root@ser named]# vi wgk.com.local
$TTL 86400
@ IN SOA wgk.com. root.wgk.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS wgk.com.
108 IN PTR www.wgk.com.
108 IN PTR mail.wgk.com. （邮件反向可有可无。）
正向文件：
[root@ser named]#vi wgk.com.zone
$TTL 86400
@ IN SOA wgk.com. root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS wgk.com.
IN MX 10 mail.wgk.com.
www IN A 192.168.1.108
mail IN A 192.168.1.108
在/etc/resolv.conf里面添加自己的域名ip
nameserver 192.168.1.108
三、启动DNS服务
[root@ser named]# service named restart
Stopping named: [ OK ]
Starting named: [ OK ]
[root@ser named]#
四、测试
nslookup 即可！
