directory< Span style= "font-family: ' The song Body '; The items are usually left out, and other configuration items can be omitted. If you do not specify listen-on Span style= "FONT-FAMILY:CALIBRI;" >named default on all interfaces udp Span style= "font-family: ' The song Body '; > port monitoring service, do not specify allow-query configuration items, The default is to respond to query requests from all clients. dump-file statistics-file etc. configuration items are used to specify the location of the cache database files, status statistics files. Added " Zone ". " In ? {}; section of the root locale, although the cache server does not have autonomous zone data, it can iterate over the root server and feed the resulting parsing results back to the customer.

sometimes in order to improve the resolution efficiency, you can also not query the root partition, but the query request from the client to the domestic carrier's DNS server (such as the 202.106.0.20 in Beijing ,202.106.148.1), the cache server receives the returned query result and then passes it to the client. Just remove the " Zone ". " In ? {... }; settings and set correctly in the global configurationForwardersparameter to achieve this function. As shown below:

[[Email protected]lhost ~]# vim/var/named/chroot/etc/named.conf

Options {

...... // omit part of the content

forwarders {202.106.0.20;202.106.148.1};

};
