Install DNSMASQ in CentOS 6.9

Dnsmasq is a lightweight, easy to configure DNS forwarder, designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. It can serve the names of local machines which are not in the global DNS.

Step 1 : Installing Dnsmasq

yum install dnsmasq

Step 2 : Configure Dnsmasq

vim /etc/dnsmasq.conf

#delete all & insert

cache-size=0
no-resolv
server=208.67.222.222 (we are using  Opendns as a dns resolver)
server=208.67.220.220
server=8.8.8.8 (dnsmasq can set multiple dns resolver,if other resolver fails,it  will ask for others resolver.)
server=8.8.4.4
domain-needed
log-queries
log-facility=/var/log/dnsmasq
no-dhcp-interface=eth0 (your network interface)
conf-dir=/etc/dnsmasq.d/

Cd to dnsmasq.d and create a config file, we will create a redirect.conf here.
To specify a domain, we need a server ip and your domain.

cd /etc/dnsmasq.d/

vim redirect.conf

address=/your-domain.com/1.2.3.4

save & quit

service dnsmasq start

Change your pc’s dns to your dns server ip address, nslookup your domain set just now.

Enjoy !
