DNS主从建立:

环境:

主服务器:10.140.165.93

从服务器:10.140.165.169

关闭防火墙,关闭selinux.

主服务器建立:

[[email protected] ~]# yum -y install bind-util bind    #安装bind服务

[[email protected] ~]# vim /etc/named.conf    #编辑主配置文件

options {
        directory       "/var/named";
        allow-recursion { 10.140.165.0/24; };    #定义递归的网段;
        notify yes;  #开启通知功能;
};

zone "." IN {         #定义根域
        type hint;
        file "named.ca";
};
zone "localhost" IN {
        type master;
        file "named.localhost";
        allow-transfer { none; };    #定义不允许区域传送;
};
zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.loopback";
        allow-transfer { none; };   #定义不允许区域传送;
};
zone "izyno.com" IN {      #定义正向解析服务
        type master;
        file "izyno.com.zone";
        allow-transfer { 10.140.165.169; };   #只允许从DNS传送
};
zone "165.140.10.in-addr.arpa" IN {    #定义反向解析;
        type master;
        file "165.140.10.zone";
        allow-transfer { 10.140.165.169; };    #只允许从DNS传送;
};

定义正向,反向区域文件:

[[email protected] named]# cd /var/named/
[[email protected] named]# ls
data  dynamic  named.ca  named.empty  named.localhost  named.loopback  slaves
[[email protected] named]# vim izyno.com.zone    #编辑正向区域
