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 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]# vi 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 "wgk.com" IN { type master; file "wgk.com.zone"; allow-update { none; }; }; zone "1.168.192.in-addr.arpa" IN { type master; file "wgk.com.local"; allow-update {none;}; }; [root@ser etc]# vi 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"; }; # 黄色为修改部分 [root@ser etc]# [root@ser etc]# cd /var/named/chroot/var/named/ 查看ll 如下： drwxrwx--- 2 named named 4096 Apr 30 13:21 data -rw-r----- 1 root named 198 Jan 17 2007 localdomain.zone -rw-r----- 1 root named 195 Jan 17 2007 localhost.zone -rw-r----- 1 root named 427 Jan 17 2007 named.broadcast -rw-r----- 1 root named 2518 Jan 17 2007 named.ca -rw-r----- 1 root named 424 Jan 17 2007 named.ip6.local -rw-r----- 1 root named 426 Jan 17 2007 named.local -rw-r----- 1 root named 427 Jan 17 2007 named.zero drwxrwx--- 2 named named 4096 Jul 27 2004 slaves [root@ser named]# cp -p localdomain.zone wgk.com.zone(一定要加-p参数，否则后面出错。) [root@ser named]# cp -p named.local wgk.com.local [root@ser named]# vi wgk.com.local $TTL 86400 @ IN SOA wgk.com. root.wgk.com. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS wgk.com. 108 IN PTR www.wgk.com. 108 IN PTR mail.wgk.com. （邮件反向可有可无。） 正向文件： [root@ser named]#vi wgk.com.zone $TTL 86400 @ IN SOA wgk.com. root ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum IN NS wgk.com. IN MX 10 mail.wgk.com. www IN A 192.168.1.108 mail IN A 192.168.1.108 在/etc/resolv.conf里面添加自己的域名ip nameserver 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 nslookup 即可！(以上测试完全通过，有什么问题谢谢提出！)
