linux下如何搭建简单的DNS Server

环境：lenovo PC, SUSE Linux 11.1 32bit,BIND 9.5.0-P2

安装步骤：

1. 采用yast自动安装。安装内容包括：bind，bind-chrootenv ，bind-devel，bind-libs，bind-utils

配置步骤：

1. whereis named,找到bind的配置文件所在目录。如下在/etc/named.conf
   

   pandora-test:~ # whereis named
   named: /usr/sbin/named /etc/named.conf /etc/named.d /usr/share/man/man8/named.8.gz

2. 修改named.conf
   2.1. 去掉注释并修改监听端口： listen-on port 53 { 172.16.39.86; };
   2.2. 添加域名解析和反向解析配置：
   

   zone "p.com" in {
   type master;
   file "p.com.zone";
   };

   zone "39.16.172.in-addr.arpa" in{
   type master;
   file "172.16.39.zone";
   };

   2.3 添加2.2中所指定的域名解析和反向解析的具体配置文件。如：p.com.zone,172.16.39.zone

   在文件夹/var/lib/named下进行添加

   p.com.zone文件内容如下：

   $TTL 1000
   @ IN SOA @ root (
       42 ; serial (d. adams)
       200S ; refresh
       4H ; retry
       1D ; expiry
       100S ) ; minimum
   @ IN NS 172.16.39.86;
   @ IN A 172.16.39.86;
   www A 172.16.39.86;
   pboss A 172.16.39.86;
   confluence A 172.16.39.86;
   redis A 172.16.39.86;
   mysql A 172.16.39.86;
   svn A 172.16.8.159;
   hudson A 172.16.8.159;
   mvnrepo A 172.16.8.159;
   jira A 172.16.8.159;

   172.16.39.zone文件内容如下：

   $TTL 1000
   @ IN SOA localhost. root.localhost. (
       42 ; serial (d. adams)
       200 ; refresh
       400 ; retry
       6000 ; expiry
       1000 ) ; minimum

   IN NS localhost.
   86 IN PTR www.p.com.

验证步骤：

    1. 启动dns server 服务：service named start

    2. 修改本地dns的配置，将首选dns的地址配置为运行dns server的服务器地址

    3. 运行命令：nslookup www.p.com

         返回结果如下：

               服务器: www.p.com
               Address: 172.16.39.86

               名称: www.p.com
               Address: 172.16.39.86

    如果返回内容为：** server can't find ww.p.com: NXDOMAIN

    则表示dns server配置有误，需检查相关配置
