在Linux服務(wù)器上配置DNS服務(wù)器，主要有以下幾種方法：

1、使用bind服務(wù)

2、使用dnsmasq服務(wù)

3、使用unbound服務(wù)

下面分別詳細(xì)介紹這三種方法的配置步驟。

使用bind服務(wù)

bind是Linux下最常用的DNS服務(wù)器軟件，其配置文件位于/etc/bind目錄下。

1、安裝bind服務(wù)

sudo aptget update
sudo aptget install bind9 bind9utils bind9doc

2、配置bind服務(wù)

編輯/etc/bind/named.conf.options文件，添加如下內(nèi)容：

forwarders {
    8.8.8.8;
    8.8.4.4;
};

這里的8.8.8.8和8.8.4.4是Google的公共DNS服務(wù)器地址，你可以根據(jù)需要修改。

3、重啟bind服務(wù)

sudo service bind9 restart

使用dnsmasq服務(wù)

dnsmasq是一個(gè)輕量級的DNS服務(wù)器和DHCP服務(wù)器，其配置文件位于/etc/dnsmasq.conf。

1、安裝dnsmasq服務(wù)

sudo aptget update
sudo aptget install dnsmasq dnsmasqbase

2、配置dnsmasq服務(wù)

編輯/etc/dnsmasq.conf文件，添加如下內(nèi)容：

server=/yourdomain.com/127.0.0.1#53353
address=/yourdomain.com/127.0.0.1

這里的yourdomain.com需要替換為你自己的域名，127.0.0.1是你的服務(wù)器IP地址，53353是你想要使用的端口號。

3、重啟dnsmasq服務(wù)

sudo service dnsmasq restart

使用unbound服務(wù)

unbound是一個(gè)安全、高效、可配置的DNS解析庫，其配置文件位于/etc/unbound/unbound.conf。

1、安裝unbound服務(wù)

sudo aptget update
sudo aptget install unbound libunbounddev

2、配置unbound服務(wù)

編輯/etc/unbound/unbound.conf文件，添加如下內(nèi)容：

server yourdomain.com {
    forwardzone yourdomain.com 86400 IN SOA ns1.yourdomain.com admin.yourdomain.com (
        2019072401 ; serial number (yyyymmdd) for this zone file version, e.g. "2019072401" or "2016070101" or "2015062901" etc... ) ; refresh every 86400 seconds (1 day) minimum TTL of 1 minute (60) maximum NS ns1.yourdomain.com admin.yourdomain.com A 192.0.2.1 (replace with your actual IP address) AAAA 2001:db8::1 (replace with your actual IPv6 address) MX 10 mailstore1.yourdomain.com (replace with your actual mail server name and IP address) MX 20 mailstore2.yourdomain.com (replace with your actual mail server name and IP address) ... add more records as needed ... ; hardcoded host names in the local domain that should not be resolved by this server include: "localhost", "localdomain", "localhost." and "localdomain."
