RedHat CentOS搭建DNS服务器正向解析

以下是基于RedHat 5或CentOS系统的正向解析(IP192.168.1.2域名为)为保证建设成功请不要错过任何一个步骤,以下所写是详细步骤挨个执行命令也能保证成功!(反向解析步骤请参考下篇)

一.安装相关软件包:为保证顺利进行请按步骤先删除再重新安装所有软件包

[root@server ~]# rpm -qa | grep bind     //查看bind相关软件包
[root@server ~]# rpm -e `rpm -qa | grep bind` --nodeps   //删除相关软件包
[root@server ~]# mount /dev/cdrom /media/    //将系统光盘挂载到/media/
[root@server media]# cd /media/Server/     //进入/media/Server/目录
[root@server Server]# rpm -vih bind-*     //再次安装相关软件包
[root@server Server]# rpm -vih caching-nameserver-9.3.3-7.el5.i386.rpm
[root@server Server]# service named start     //重启named服务

二.修改主配置文件
[root@server Server]# cd /var/named/chroot/etc/    //进入/var/named/chroot/etc/目录
[root@server etc]# vim named.caching-nameserver.conf   //修改主配置文件
----------------------------------------------------------------------
options {
        listen-on port 53 { any; };      //修改为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; };      //修改为any
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
view localhost_resolver {
        match-clients      { any; };      //修改为any
        match-destinations { any; };     //修改为any
        recursion yes;
        include "/etc/named.rfc1912.zones";
};
----------------------------------------------------------------------

三.修改主机配置文件的扩展文件
[root@server etc]# vim named.rfc1912.zones    //修改主机配置文件的扩展名在最后一行添加
----------------------------------------------------------------------
zone "linuxidc.com" IN {       //IN可有可无
        type master;       //类型为主域
        file "linuxidc.com";       //域配置文件
};
---------------------------------------------------------------------
四.建立linuxidc.com的域配置文件

[root@server etc]# cd /var/named/chroot/var/named/   //进入/var/named/chroot/var/named/目录
[root@server named]# cp named.local linuxidc.com    //拷贝域配置文件
[root@server named]# vim linuxidc.com
