Debian配置主从DNS服务器

知里

Bind是使用最广泛的DomainName Server

• DNS主服务器:192.168.5.8
• DNS辅服务器:192.168.4.9

主服务安装软件

apt-get install bind9

修改/etc/bind/named.conf.local
添加正向解析文件

zone "hlooc.cn" {
	type master;
	file "/etc/bind/hlooc.cn.hosts";
	masterfile-format text;
	allow-update {192.168.4.9;};//从服务器ip
	};

新增数据文件cp db.local hlooc.cn.hosts添加如下记录

;
; BIND data file for local loopback interface
;
$TTL	604800
@	IN	SOA	localhost. root.localhost. (
			      2		; Serial
			 604800		; Refresh
			  86400		; Retry
			2419200		; Expire
			 604800 )	; Negative Cache TTL
;
@	IN	NS	localhost.
@	IN	A	127.0.0.1
@	IN	AAAA	::1
omv	IN	A	192.168.4.10

修改/etc/bind/named.conf.options

	forwarders {
		222.246.129.80;//公共DNS
		114.114.114.114;//公共DNS
	};

重启服务

rndc reload

从服务安装软件与主服务一致

修改/etc/bind/named.conf.local

zone "hlooc.cn" {
	type slave;
	masters {192.168.5.8;};
	file "/etc/bind/slaves/hlooc.cn.hosts";
	masterfile-format text;
	};

修改/etc/bind/named.conf.options与主服务器一致

重启服务

rndc reload
