简单的配置dnsmasq作为本地dns缓存层

一、安装

yum search dnsmasq

二、配置

vim /etc/dnsmasq.conf

listen-address=127.0.0.1

strict-order

cache-size=2048

# 其实dnsmasq的配置有很多项，这里选择这几项只保证了最基本的。listen-address监听地址；strict-order按照/etc /resolv.conf中nameserver的顺序依次使用，默认时dnsmasq会随机的调用/etc/resolv.conf中的 nameserver；cache-size缓存解析条数，默认是150

/bin/sed -i ’1i\nameserver 127.0.0.1′ /etc/resolv.conf

三、部署脚本

#!/bin/bash

init_dnsmasq(){

/bin/sed -i ’1i\nameserver 127.0.0.1′ /etc/resolv.conf

yum install -y dnsmasq

cat << shanks > /etc/dnsmasq.conf

listen-address=127.0.0.1

strict-order

cache-size=2048

shanks

chkconfig dnsmasq on

/etc/init.d/dnsmasq start

}

init_dnsmasq
