Most DNS cache servers exist in small enterprises. they are not responsible for domain name resolution and are only used to help users query domain name information from other DNS servers. The queried information is saved locally to facilitate the next use of the domain name. it is valid to shorten the domain name query time and save the local information.

The specific configuration is as follows:

# Wget ftp: // 192.168.1.31/bind-9.8.1.tar.gz download source package

# Tar zxvf bind-9.8.1.tar.gz extract source package

# Cd bind-9.8.1 go to the decompressed Directory

#./Configure -- prefix =/usr/local/named -- enable-threads -- with-openssl = no pre-compilation configuration

# Make & make install compile and install

#/Usr/local/named/sbin/rndc-confgen>/usr/local/named/etc/rndc. conf generate the key file of the rndc control command

# Tail-10/usr/local/named/etc/rndc. conf | head-9 | sed s/# \ // g>/usr/local/named/etc/named. conf from rndc. extract named. key used by conf

# Vi/usr/local/named/etc/named. conf edit named. conf

Add the following content to named. conf:

# Specify the resource file storage path and pid file name.

Options {

Directory "/usr/local/named/dns/zone ";

Pid-file "/usr/local/named/dns/named. pid ";

};

 

# Point to the resource file with the server

Zone "." IN {

Type hint;

File "named. root ";

};

 

# Resource files recorded by local authoritative DNS

Zone "localhost" IN {

Type master;

File "localhost. zone ";

Allow-update {none ;};

};

 

# Resource files recorded by the local authoritative reverse DNS

Zone "0.0.127.in-addr. arpa" IN {

Type master;

File "localhost. rev ";

Allow-update {none ;};

};

# Mkdir-p/usr/local/named/dns/zone

# Cd/usr/local/named/dns/zone/enter the resource file storage directory

#/Usr/local/named/bin/dig | grep-v "^;">/usr/local/named/dns/zone/named. root uses the dig command to generate named. root service resource file

If you cannot access the Internet, you can also download the latest online named. root file.

The content of the named. root file is as follows:
