Purpose: When a LAN User accesses a domain name, the user intercepts the access to the specified IP address and caches the IP address to save bandwidth.
Configuration:
1;> Yum install dnsmasq-y
2;> VI/etc/dnsmasq. conf
Resolve-file =/etc/dnsmasq. resolv. conf
Addn-hosts =/etc/dnsmasq. Hosts
Resolve-file specifies where dnsmasq obtains the upstream DNS server, which is obtained from/etc/resolv. conf by default.
Addn-hosts specifies the file from which dnsmasq reads the "address domain name" record. The default value is system file/etc/hosts;
By default, listen-address is monitored on all NICs.
