在这篇文章中我们来了解一下“如何用CentOS搭建自己的DNS服务器？”，一些朋友可能会遇到这方面的问题，对此在下文小编向大家来讲解，内容详细，易于理解，希望大家阅读完这篇能有收获哦，有需要的朋友就往下看吧！ 系统环境：CENTOS6.4 1、安装软件： yum install bind -y 2、配置，编辑完成以后的主配置文件内容如下： [root@centos64 yum.repos.d]# cat /etc/named.conf // // named.conf // // Provided by Red Hat bind 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. // options { listen-on port 53 { 193.168.120.91; }; //listen-on-v6 port 53 { ::1; }; #此处须注释掉，否则在IPV4的网络环境下，添加反向解析以后，DNS服务不能启动 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"; allow-query { any; }; recursion yes; dnssec-enable no; #此处将yes改为no,否则转发解析互联网的域名失败 dnssec-validation no; #此处将yes改为no,否则转发解析互联网的域名失败 /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "."
