1、安装相关组件

yum -y install bind bind-chroot（bind-chroot为可选组件）

2、配置文件

①chroot环境：

vi /etc/named/chroot/etc/named.conf

options{

directory "/var/named/chroot/var/named/";

};

zone "user.test.com" IN {

type master;

file "user.test.com.zone";

allow-update { none; };

};

vi /var/named/chroot/var/named/user.test.com.zone

$ TTL 86400

@ IN SOA user.test.com root (

1H

10M

7D

1D

)

@ IN NS user.test.com.

user.test.com. IN A 192.168.1.110

②非chroot环境

vi /etc/named.conf

options{

directory "/var/named";

};

zone "user.test.com" IN {

type master;

file "user.test.com.zone";

allow-update { none; };

};

vi /var/named/user.test.com.zone

$ TTL 86400

@ IN SOA user.test.com root (
