RedHat5搭建简单DNS服务器

服务安装

• yum install bind
• yum install bind-chroot
• yum install caching-nameserver-9.3.4-6.P1.el5.i386.rpm  //dns配置文件模版

搭建目标

• DNS服务主机IP：192.168.1.150
• DNS服务存储网站目录
• www.abc.test1 正向解释 192.168.1.151
• 192.168.1.151 反向解释 www.abc.test1

DNS全局配置文件

• 启动DNS服务
• service named start
• vi /var/named/chroot/etc/named.caching-nameserver.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; };  //anylisten-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; };   //any};logging {channel default_debug {file "data/named.run";severity dynamic;};};view localhost_resolver {match-clients     { localhost; };match-destinations { localhost; };recursion yes;include "/etc/named.rfc1912.zones";};

DNS区域配置文件

vi /var/named/chroot/etc/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 "localdomain" IN {type master;file "localdomain.zone";allow-update { none; };};zone "localhost" IN {type master;file "localhost.zone";allow-update { none; };};zone "0.0.127.in-addr.arpa" IN {type master;file "named.local";allow-update { none; };};zone "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.ip6.local";allow-update { none; };};zone "255.in-addr.arpa" IN {type master;file "named.broadcast";allow-update { none; };};zone "0.in-addr.arpa" IN {type master;file "named.zero";allow-update { none; };};zone "abc.test1" IN {type master;file "abc.test1.zone";allow-update {none;};};zone "1.168.192.in-addr.arpa" IN {type master;file "192.168.1.local";allow-update {none;};};

创建DNS域名文件

• cd /var/named/chroot/var/named
• cp -a localhost.zone abc.test1.zone  
• cp -a named.local 192.168.1.local  //cp命令的时候，谨记带上参数-a，因为文件有权限方面问题，如果不是-a可能无法启动DNS服务器

重启DNS服务
service named restart  //确认区域文件命名没错，一步步确认，不要走回头路,DNS配置很敏感的

修改区域配置文件

vi localhost.zone abc.test1.zone

$TTL 86400@     IN SOA www.abc.test1. root.abc.test1. (42; serial (d.adams)3H; refresh15M; retry1W; expiry1D); minimum@ IN NS www.abc.test1.www IN A 192.168.1.151

vi 192.168.1.local

$TTL 86400@     IN SOA www.abc.test1. root.abc.test1. (1997022700; serial (d.adams)28800; refresh14400; retry3600000; expiry86400); minimum@ IN NS www.abc.test1.111 IN A www.abc.test1.

重启DNS服务

service named restart

校验DNS情况

配置客户端DNS服务器

• vi /etc/resolve.conf 
• 输入nameserver 192.168.1.150

填写完毕后，终端输入nslookup www.chipcore.test1 ，有信息返回代表正确

主要，DNS对语法非常敏感，多备份，一步步测试，注意域名是www.abc.test1. 后面是带一个“.”号的

另外，测试客户机注意清空DNS缓存。
