Bind Named DNS - Setup DNSSEC on a BIND DNS server

Make the following configurations in the /etc/named.conf file.

dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;


Move to the directory where your forward and reverse zone files are located, which is /var/named in this example, and create .key and .private files. Replace with the name of the domain you want to secure. This should create the public and private key files, such as and

[root@server1 ~]# cd /var/named/
[root@server1 ~]# dnssec-keygen -a RSASHA1 -b 2048 -n ZONE


Append the public key to the forward zone file. Make sure you use >> and not >, so that you do not overwrite your zone file.

[root@server1 ~]# cat*.key >>


Sign the zone file.

[root@server1 ~]# dnssec-signzone -e +3024000 -´┐ŻN INCREMENT


Restart named.

[root@server1 ~]# service named restart
