Dnsmasq domain name resolution system installation and configuration

Dnsmasq is much easier to use than bind, it can do forward and reverse DNS resolution, and supports DHCP services. It can also be used as an internal dns server.

By default, dnsmasq uses the system's /etc/resolv.conf and reads the /etc/hosts file.

1. Install dnsmasq software

yum install dnsmasq

2. Edit the configuration file /etc/dnsmasq.conf

cache-size= 10000　　 #Number of cache entries 
resolv - file =/etc/dnsmasq- resolv.conf #Upgrade DNS
addn -hosts =/etc/ dnsmasq.hosts #Local domain name configuration file (pan-domain name is not supported)
log-queries
log-facility=/var/log/dnsmasq.log
local -ttl= 600　　#DHCP lease time 
conf -dir =/etc / dnsmasq.d

3. Modify the upstream DNS configuration file /etc/dnsmasq-resolv.conf

nameserver x.x.x.x

3.1 Edit the local domain name configuration file /etc/dnsmasq.hosts (add the internal addresses and domain names that need to be resolved) (reload will take effect)

127.0 . 0.1 www.qq.com #IP domain name

3.2 Edit the configuration file /etc/dnsmasq.d/address.conf that supports PAN domain name (you need to restart the service to take effect after editing)

address=/www.taobao.com/ 127.0 . 0.1　　 #Forward parsing
ptr -record= 127.0 . 0.1 . in - addr.arpa,www.taobao.com #Reverse parsing (optional)

address =/baidu.com/ 127.0 . 0.1 #Pan     domain name resolution

 4. Configure log rotation, edit /etc/logrotate.d/dnsmasq

/var/log/dnsmasq.log {
    daily
    copytruncate
    missingok
    rotate 30
    compress
    notifempty
    dateext
    size 200M
}
