MySQL


MySQL tables (and samples):



DROP TABLE IF EXISTS `domains`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `domains` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `master` varchar(128) DEFAULT NULL,
  `last_check` int(11) DEFAULT NULL,
  `type` varchar(6) NOT NULL,
  `notified_serial` int(11) DEFAULT NULL,
  `account` varchar(40) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `name_index` (`name`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;

INSERT INTO `domains` VALUES (1,'lunasys.fr',NULL,NULL,'NATIVE',NULL,NULL);


DROP TABLE IF EXISTS `records`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `records` (

) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;

INSERT INTO `records` VALUES (3,1,'as.www.lunasys.fr','A','3.1.1.1',600,NULL,NULL),(4,1,'us.www.lunasys.fr','A','2.1.1.1',600,NULL,NULL),(5,1,'eu.www.lunasys.fr','A','4.1.1.1',600,NULL,NULL);


DROP TABLE IF EXISTS `supermasters`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `supermasters` (
  `ip` varchar(25) NOT NULL,
  `nameserver` varchar(255) NOT NULL,
  `account` varchar(40) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;





In pdns.d/pdns.local, add:



gmysql-host=127.0.0.1
gmysql-user=root
gmysql-password=<pass>
gmysql-dbname=pdns








Geo


In pdns.d/pdns.local, add:



geo-zone=lunasys.fr
#geo-ns-records=ns0.lunasys.fr
geo-ip-map-zonefile=/etc/powerdns/zz.countries.nerd.dk.rbldnsd
geo-maps=/etc/powerdns/geo-maps



Write geo-maps/lunasys:



$RECORD www
$ORIGIN lunasys.fr.
56 eu.www
344 as.www
250 eu.www
840 us.www
124 us.www
0 eu.www



Finally retrieve countries zone file with the following rsync command:



rsync -avz rsync://countries-ns.mdc.dk/zone .



And copy the zz.countries.nerd.dk.rbldnsd in /etc/powerdns/
