DNS主从服务,子域授权,view视图,日志系统,压力测试
DNS性能测试工具queryperfDNS查询过程:
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:
[root@cnhzdhcp16593 ~]# yum -y install bind-util bind #安装bind服务
[root@cnhzdhcp16593 ~]# 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
};

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:
