Instruction for BIND to insteract with MySQL
mysqladmin -u root password agnello
mysqladmin -u root -p create binddlzdb
Change to the MySQL database administration and add the bind-dlz user
and password:
USE mysql;
INSERT INTO user (Host, User, Password) VALUES
('localhost','binddlzuser',password('binddlzpassword'));
INSERT INTO db (Host, Db, User, Select_priv) VALUES
('localhost','binddlzdb','binddlzuser','Y');
Setup the rights for the just created users:
FLUSH PRIVILEGES;
GRANT USAGE ON binddlzdb.* TO binddlzuser@localhost;
GRANT SELECT, INSERT, DELETE, UPDATE ON binddlzdb.* TO binddlzuser@localhost;
USE binddlzdb;
we create the record table . The table "records" holds all information
about your zones,
CREATE TABLE `records` ( `id` int(10) unsigned NOT NULL
auto_increment, `zone` varchar(255) NOT NULL, `ttl` int(11) NOT NULL
default '86400', `type` varchar(255) NOT NULL, `host` varchar(255) NOT
NULL default '@', `mx_priority` int(11) default NULL, `data` text,
`primary_ns` varchar(255) default NULL, `resp_contact` varchar(255)
default NULL, `serial` bigint(20) default NULL, `refresh` int(11)
default NULL, `retry` int(11) default NULL, `expire` int(11) default
NULL, `minimum` int(11) default NULL, PRIMARY KEY (`id`), KEY `type`
(`type`), KEY `host` (`host`), KEY `zone` (`zone`) );
then create xfr table . "xfr" can be used to allow AXFR/IXFR zone
transfers per zone and host
CREATE TABLE `xfr` ( `zone` varchar(255) NOT NULL, `client`
varchar(255) NOT NULL, KEY `zone` (`zone`), KEY `client` (`client`) );
Edit the named.conf
vi /etc/named.conf
dlz "Mysql zone" {
database "mysql
{host=127.0.0.1 dbname=binddlzdb user=binddlzuser pass=binddlzpassword}
{select zone from dns_records where zone = '%zone%'}
{select ttl, type, mx_priority, case when lower(type)='txt' then
concat('\"', data, '\"')
else data end from dns_records where zone = '%zone%' and host
= '%record%'
and not (type = 'SOA' or type = 'NS')}
{select ttl, type, mx_priority, data, resp_person, serial, refresh,
retry, expire, minimum
from dns_records where zone = '%zone%' and (type = 'SOA' or type='NS')}
{select ttl, type, host, mx_priority, data, resp_person, serial,
refresh, retry, expire,
minimum from dns_records where zone = '%zone%' and not (type =
'SOA' or type = 'NS')}
{select zone from xfr_table where zone = '%zone%' and client = '%client%'}
{update data_count set count = count + 1 where zone ='%zone%'}";
};
