RHEL5.0 搭建DNS服务器

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

[root@ser ~]# yum -y install bind* caching-*

 

 

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]# vim 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 "yjw.com" IN {
        type master;
        file "yjw.com.zone";
        allow-update { none; };
};
 

 
zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.1.local";
       allow-update {none;};
 
};

[root@ser etc]# vim 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";
};

       # 红色为修改部分

[root@ser named]# cp -p localdomain.zone yjw.com.zone
[root@ser named]# cp -p named.local 192.168.1.local

[root@ser named]# vim  192.168.1.local
$TTL    86400
@       IN      SOA     yjw.com. root.yjw.com.  (

[root@ser named]#vim yjw.com.zone

                                    42              ; serial (d. adams)
                                    3H              ; refresh

www       IN  CNAME        ns.yjw.com.
mail      IN A            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

[root@ser named]# nslookup
>>
Server:         127.0.0.1
Address:        127.0.0.1#53
 
Non-authoritative answer:
     canonical name = .
Name:  
Address: 61.135.253.9
Name:  
Address: 61.135.253.10

> > 192.168.1.2
Server:         127.0.0.1
Address:        127.0.0.1#53
 
2.1.168.192.in-addr.arpa        name = .
2.1.168.192.in-addr.arpa        name = mail.yjw.com.
