一、安装

yum install bind

 

二、配置

1. /etc/named.conf

1 // 2 // named.conf 3 // 4 // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS 5 // server as a caching only nameserver (as a localhost DNS resolver only). 6 // 7 // See /usr/share/doc/bind*/sample/ for example named configuration files. 8 // 9 // See the BIND Administrator's Reference Manual (ARM) for details about the10 // configuration located in /usr/share/doc/bind-{version}/Bv9ARM.html11 12 options {13 listen-on port 53 { any; };14 listen-on-v6 port 53 { ::1; };15 directory "/var/named";16 dump-file "/var/named/data/cache_dump.db";17 statistics-file "/var/named/data/named_stats.txt";18 memstatistics-file "/var/named/data/named_mem_stats.txt";19 allow-query { 0.0.0.0/0; };20 21 /* 22 - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.23 - If you are building a RECURSIVE (caching) DNS server, you need to enable 24 recursion. 25 - If your recursive DNS server has a public IP address, you MUST enable access 26 control to limit queries to your legitimate users.

IN {53 type hint;54 file "named.ca";55 };56 57 include "/etc/named.rfc1912.zones";58 include "/etc/named.root.key";

配置说明

a. 第13行：启动监听地址，默认启动在localhost上，需要修改为监听所有的地址。修改为{ any; }b. 第19行：允许查询的地址和端口，默认是本地查询，需要修改为允许任意地址。修改为 { 0.0.0.0/0; }c. 第57行，引出了另外一个配置/etc/named.rfc1912.zonesd. 第15行，引出了一个域名信息配置文件目录/var/named

 

2. /etc/named.rfc1912.zones

1 // named.rfc1912.zones: 2 // 3 // Provided by Red Hat caching-nameserver package  4 // 5 // ISC BIND named zone configuration for zones recommended by 6 // RFC 1912 section 4.1 : localhost TLDs and address zones 7 // and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt 8 // (c)2007 R W Franks 9 // 10 // See /usr/share/doc/bind*/sample/ for example named configuration files.11 //12 13 zone "localhost.localdomain" IN {14 type master;15 file "named.localhost";16 allow-update { none; };17 };18 19 zone "localhost" IN {20 type master;21 file "named.localhost";22 allow-update { none; };23 };24 25 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 {26 type master;27 file "named.loopback";28 allow-update { none; };29 };30 31 zone "1.0.0.127.in-addr.arpa" IN {32 type master;33 file "named.loopback";34 allow-update { none; };35 };36 37 zone "0.in-addr.arpa" IN {38 type master;39 file "named.empty";40 allow-update { none; };41 };42 43 //vvtest.com 正向配置44 zone "vvtest.com" IN {45 type master;46 file "named.vvtest.com";47 allow-update { none; };48 };49 //vvtest.com 逆向配置50 zone "25.168.192.in-addr.arpa" IN {51 type master;52 file "192.168.25.arpa";53 allow-update { none; };54 };

配置说明：

a. 第43~48行，添加域名的正向配置b. 第50~54行，添加域名的逆向配置c. 第46行，引出了配置文件named.vvtest.comd. 第52行，引出了配置文件192.168.25.arpae. c和d中的配置文件目录为/var/named（由named.conf配置的）

3. /var/named/named.vvtest.com

1 $TTL 1D 2 @    IN SOA    vvtest.com. rname.invalid. ( 3 0    ; serial 4 1D    ; refresh 5 1H    ; retry 6 1W    ; expire 7 3H )    ; minimum 8 NS    @ 9 A    127.0.0.110 AAAA    ::111 www IN A 192.168.25.12812 mail IN A 192.168.25.128

配置说明：

a. 第2行，是【vvtest.com.】，最后又一个【.】b. 第11行，配置的是域名www.vvtest.com，服务器地址是192.168.25.128c. 第12行，配置的是域名mail.vvtest.com，服务器地址是192.168.25.128

4. /var/named/192.168.25.arpa

1 $TTL 1D 2 @ IN SOA vvtest.com. rname.invalid. ( 3 0 ; serial 4 1D ; refresh 5 1H ; retry 6 1W ; expire 7 3H ) ; minimum 8 NS @ 9 AAAA ::110 128 PTR www.vvtest.com.

 

三、测试

1. 启动systemctl start named或者service named start2. 配置测试机的DNS1服务器地址为192.168.25.1283. 从测试机上执行ping www.vvtest.com，如果有收到ping包，恭喜你。

 

附、一个个人遇到的纠结无比的问题

1. 服务器启动，无法Ping通。2. 花了大量的时间在反复检查所有的配置文件及选项，确保每一个字符都是一样的。3. 看了日志才发现是读取配置文件的时候，permission denied。4. chown -R root.named 权限不对的文件（named.vvtest.com和192.168.25.arpa）5. 论日志的重要性！没有日志，就是抓虾~
