An example of bind9 installation and configuration in linux

1. Install BIND
1. Download BIND http://www.isc.org can also go to this site to download bind9 dns software.
2. Compile and install

Copy codeCode: # tar zxvf bind-9.4.0.tar.gz
# Cd bind-9.4.0
#./Configure sysconfdir =/etc // more installation options./configure -- help
# Make
# Make install

2. Configure BIND
A. create the required file
1)./etc/named. conf
# Save vi/etc/named. conf or touch/etc/named. conf

2)./etc/rndc. conf
# Rndc-confgen>/etc/rndc. conf

B. Create a directory/var/named
# Mkdir/var/named

B. edit/etc/named. conf as follows:

Copy codeThe Code is as follows: options {
Directory "/var/named"; // indicates that the default database file is in/var/named.
// Pid-file "/var/run/named. pid"; // the path of the running PID file, which is used to start named by another user
};
Zone "." {// create the root domain

Type hint;
File "named. ca ";
};
Zone "localhost" {// create a localhost domain
Type master;
File "named. local ";
};
Zone "example.com" {// create example.com domain
Type master;
File "example.com. zone ";
};
Zone "0.0.127.in-addr. arpa" {// anti-resolution of localhost
Type master;
File "127.0.0.zone ";
};
Reverse resolution of zone "100.168.192.in-addr. arpa" {// example.com
Type master;
File "192.168.100.zone ";
};
// This file must be copied at the end of/etc/rndc. conf to use # tail + 13/etc/rndc. conf>/etc/named. conf
# Use with the following in named. conf, adjusting the allow list as needed:
Key "rndc-key "{
Algorithm hmac-md5;
Secret "HWM3L + e7LWDZJJ/dJEzQEw = ";
};

Controls {
Inet 127.0.0.1 port 953
Allow {127.0.0.1;} keys {"rndc-key ";};
};
# End of named. conf

D. Create a data file name in/var/named, which is determined by the file parameter in named. conf.
Named. conf shows named. ca, named. local, example.com. zone, 127.0.0.zone, and 192.168.100.zone.
1. named. ca
# Dig-t NS.>/var/named. ca
2. Add named. local # vi/var/named. local to the following content:
