RedHat CentOS搭建DNS服务器反向解析详细步骤

RedHat CentOS搭建DNS服务器反向解析详细步骤

以下是基于RedHat 5或CentOS系统的反向解析(IP192.168.1.2域名为www.linuxboy.net)为保证建设成功请不要错过任何一个步骤,以下所写是详细步骤挨个执行命令也能保证成功!如果已做好正向解析(详细参考上篇文章)并通过测试的情况下课直接从第三步开始

一.安装相关软件包:为保证顺利进行请按步骤先删除再重新安装所有软件包

[root@server ~]# rpm -qa | grep bind //查看bind相关软件包


[root@server ~]# rpm -e `rpm -qa | grep bind` --nodeps //删除相关软件包
[root@server ~]# mount /dev/cdrom /media/ //将系统光盘挂载到/media/
[root@server media]# cd /media/Server/ //进入/media/Server/目录(如果是CentOS系统则进入/media/CentOS/目录)
[root@server Server]# rpm -vih bind-* //再次安装相关软件包
[root@server Server]# rpm -vih caching-nameserver-9.3.3-7.el5.i386.rpm //在CentOS中软件包名称有所不一样所以要巧用Tab补全
[root@server Server]# service named start //重启named服务


二.修改主配置文件
[root@server Server]# cd /var/named/chroot/etc/ //进入/var/named/chroot/etc/目录
[root@server etc]# vim named.caching-nameserver.conf //修改主配置文件
----------------------------------------------------------------------
options {
listen-on port 53 { any; }; //修改为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; }; //修改为any
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { any; }; //修改为any
match-destinations { any; }; //修改为any
recursion yes;
include "/etc/named.rfc1912.zones";
};
----------------------------------------------------------------------

如果前面已经做好正向解析那么我们可以直接从这里开始
三.修改主机配置文件的扩展文件
[root@localhost ~]# cd /var/named/chroot/etc/ //进入/var/named/chroot/etc/目录
[root@server etc]# vim named.rfc1912.zones //修改主机配置文件的扩展名;在最后一行添加如下
----------------------------------------------------------------------
zone "1.168.192.in-addr.arpa" IN { //将你的主机IP地址前三位反写
type master;
file "192.168.1.rev";
};
---------------------------------------------------------------------

四.建立192.168.1.rev的域配置文件
[root@server etc]# cd /var/named/chroot/var/named/ //进入/var/named/chroot/var/named/目录
[root@localhost named]# cp named.local 192.168.1.rev //拷贝域配置文件192.168.1.rev
[root@localhost named]# vim 192.168.1.rev
--------------------------------------------------------------------
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
2 IN PTR www.linuxboy.net. //修改最后一行为(我的IP为192.168.1.2域名为www.linuxboy.net)

--------------------------------------------------------------------
[root@server named]# bind-chroot-admin -s //自动完成组和权限设置(在CentOS中可能会提示/usr/bin/find: /var/log/named.log: 没有那个文件或目录)
[root@server named]# service named restart //重启named服务

五.测试验证
为了验证成功最好修改本地DNS，将服务器改为自己的IP
vi /etc/resolv.conf
nameserver 192.168.1.2
:wq //保存退出
[root@localhost named]# host 192.168.1.2 //在本机验证解析成功

192.168.1.2.in-addr.arpa domain name pointer www.linuxboy.net.

C:Documents and SettingsAdministrator>nslookup //远端验证解析成功
*** Cant find server name for address 219.244.93.2: Non-existent domain
*** Default servers are not available
Default Server: UnKnown
Address: 219.244.93.2 //本来我的DNS为219.244.93.2

> server 192.168.1.2 //更改解析主机
Default Server: [192.168.1.2]
Address: 192.168.1.2

> www.linuxboy.net
Server: [192.168.1.2]
Address: 192.168.1.2

Name: www.linuxboy.net
Address: 192.168.1.2
