简单的配置dnsmasq作为本地dns缓存层

配置dnsmasq

一、安装

yum search dnsmasq

二、配置

vim /etc/dnsmasq.conf
listen-address=127.0.0.1strict-ordercache-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/bashinit_dnsmasq(){/bin/sed -i ’1i\nameserver 127.0.0.1′ /etc/resolv.confyum install -y dnsmasqcat << shanks > /etc/dnsmasq.conflisten-address=127.0.0.1strict-ordercache-size=2048shankschkconfig dnsmasq on/etc/init.d/dnsmasq start}init_dnsmasq
