In this step, you need to make all queries to be sent to dnsmasq by adding the localhost addresses as the only nameservers in /etc/nf file. # dnsmasq -testĬheck dnsmasq Configuration Configuring dnsmasq with /etc/nf Fileġ0. Save the file and check the configuration file syntax for errors as shown. Then you can force your local domain to an IP address(es) using the address option as shown. Next, also define the upstream DNS server for non-local domains using the server option (in the form server=dns_server_ip) as shown. To set the domain for dnsmasq, which means DHCP clients will have fully qualified domain names as long as the set domain is matched, and sets the “ domain” DHCP option for all clients. If you want to have a domain (which you can set as shown next) automatically added to simple names in a hosts-file, uncomment the expand-hosts option. Related to the above, you can restrict the interface dnsmasq listens on using the interface option (add more lines for more than one interface). To use your CentOS/RHEL server to listen for DHCP and DNS requests on the LAN, set the listen-address option to its LAN IP addresses (remember to include 127.0.0.1) as shown. The listen-address the option is used to set the IP address, where dnsmasq will listen on. Now open the /etc/nf file using your favorite text-based editor and make the following suggested configuration settings. The dnsmasq server can be configured via the /etc/nf file (which contains well commented and explained options), and user-defined configuration files can also be added in the /etc/dnsmasq.d directory.ĭNS is enabled by default, so before making any changes, make sure to create a backup of /etc/nf file. Start and Verify dnsmasq Status Configuring dnsmasq Server in CentOS and RHEL Linuxģ. Besides, check its status to ensure that it is up and running using the following systemctl commands. Once the dnsmasq package installation is complete, you need to start the dnsmasq service for now and enable it to automatically start at system boot. The dnsmasq package is available in the default repositories and can be easily installed using the YUM package manager as shown. Installing dnsmasq in CentOS and RHEL Linuxġ.

A DNS caching server answers recursive requests from clients so that the DNS query can be resolved faster, thus improving DNS lookup speeds to previously visited sites.ĭnsmasq is a lightweight, easy to configure DNS forwarder, DHCP server software and router advertisement subsystem for small networks. A DNS forwarder on a LAN forwards DNS queries for non-local domain names to upstream DNS servers (outside that network).
