linux下如何搭建简单的DNS Server

woodbird

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

安装步骤：

• 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：

• 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
  
• 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
