debian 11搭建主从DNS

环境
NDS主服务器：192.168.1.4
DNS从服务器：192.168.1.5

安装包，主从都安装

apt install -y bind9 dnsutils

配置主服务器

#配置dns
echo "nameserver 192.168.1.4" > /etc/resolv.conf

#主配置文件
cd /etc/bind/
vim named.conf.default-zones
添加以下内容
zone "skills.com" {
	type master;
	allow-update { 192.168.1.5; };
	file "/etc/bind/db.zzz";
};

zone "1.168.192.in-addr.arpa" {
	type master;
	allow-update { 192.168.1.5; };
	file "/etc/bind/db.fff";
};

cp db.local db.zzz
cp db.127 db.fff
