Linux搭建DNS服务器记录

##1、安装后named -v查看版本号，方便查找相应教程

##2、编辑/etc/named.conf

//
// named.conf
//
// Provided by Red Hat bind 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.
//
// See the BIND Administrator's Reference Manual (ARM) for details about the
// configuration located in /usr/share/doc/bind-{version}/Bv9ARM.html

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";
	allow-query     { any; };

	/* 
	 - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
	 - If you are building a RECURSIVE (caching) DNS server, you need to enable 
	   recursion. 
	 - If your recursive DNS server has a public IP address, you MUST enable access 
	   control to limit queries to your legitimate users. Failing to do so will
	   cause your server to become part of large scale DNS amplification 
	   attacks. Implementing BCP38 within your network would greatly
	   reduce such attack surface 
	*/
	recursion yes;

	dnssec-enable yes;
	dnssec-validation yes;
	dnssec-lookaside auto;

	/* Path to ISC DLV key */
	bindkeys-file "/etc/named.iscdlv.key";

	managed-keys-directory "/var/named/dynamic";

	pid-file "/run/named/named.pid";
	session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
	type hint;
	file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

##3、修改/etc/named.rfc1912.zones
增加一个正向和反向解析

// 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
// and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
// (c)2007 R W Franks
// 
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

zone "localhost.localdomain" IN {
	type master;
	file "named.localhost";
	allow-update { none; };
};

zone "localhost" IN {
	type master;
	file "named.localhost";
	allow-update { none; };
};

zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
	type master;
	file "named.loopback";
	allow-update { none; };
};

zone "1.0.0.127.in-addr.arpa" IN {
	type master;
	file "named.loopback";
	allow-update { none; };
};

zone "0.in-addr.arpa" IN {
	type master;
	file "named.empty";
	allow-update { none; };
};

zone "carlpc.comcn" IN {
	type master;
	file "named.carlpc.comcn";
	allow-update { none; };
};

zone "197.168.192.in-addr.arpa" IN {
	type master;
	file "named.197.168.192.zone";
	allow-update { none; };
};

##4、在/var/named下增加两个配置文件named.carlpc.comcn和named.197.168.192.zone
分别为

$TTL 1D
@	IN SOA	@ rname.invalid. (
					0	; serial
					1D	; refresh
					1H	; retry
					1W	; expire
					3H )	; minimum
	IN	NS	live.carlpc.comcn.
live.carlpc.comcn.	IN	A	10.8.227.122

$TTL 1D
@	IN SOA	@ rname.invalid. (
					0	; serial
					1D	; refresh
					1H	; retry
					1W	; expire
					3H )	; minimum
197.168.192.in-addr.arpa.	IN	NS	www.test.comcn
128	IN	PTR	www.test.comcn
129	IN	PTR	mail.test.comcn
130	IN	PTR	lib.test.comcn
