Kutulutsidwa kwa seva yovomerezeka (yovomerezeka) ya DNS ya PowerDNS Authoritative Server 4.7, yokonzedwa kuti ikonzekere kubwerera kwa madera a DNS, yasindikizidwa. Malinga ndi omwe akupanga polojekitiyi, PowerDNS Authoritative Server imagwira pafupifupi 30% ya madera onse ku Europe (ngati tingoganizira madera omwe ali ndi siginecha ya DNSSEC, ndiye 90%). Khodi ya polojekitiyi imagawidwa pansi pa layisensi ya GPLv2.
PowerDNS Authoritative Server imapereka mwayi wosunga zidziwitso za domain m'malo osiyanasiyana, kuphatikiza MySQL, PostgreSQL, SQLite3, Oracle, ndi Microsoft SQL Server, komanso mu LDAP ndi mafayilo osavuta amtundu wa BIND. Kubweza kwa yankho kumatha kusefedwanso (mwachitsanzo, kusefa sipamu) kapena kutumizidwanso polumikiza othandizira anu ku Lua, Java, Perl, Python, Ruby, C ndi C ++. Zina mwazinthuzi, palinso zida zosonkhanitsira ziwerengero zakutali, kuphatikiza kudzera pa SNMP kapena pa Webusayiti API (seva ya http imapangidwira ziwerengero ndi kasamalidwe), kuyambitsanso pompopompo, injini yolumikizidwa yolumikizira othandizira muchilankhulo cha Lua. , kutha kulinganiza katundu malinga ndi malo omwe kasitomala ali .
Zatsopano zazikulu:
- Thandizo lowonjezera pamndandanda wamagawo ("Catalog Zones"), zomwe zimathandizira kukonzanso kwa ma seva achiwiri a DNS chifukwa m'malo mofotokozera ma rekodi osiyana pagawo lililonse lachiwiri pa seva yachiwiri, kabukhu kagawo kakang'ono kamakonzedwa pakati pa magawo achiwiri. ma seva oyambirira ndi apamwamba. Kusamutsa kwa chikwatu kukakhala kofanana ndi kusamutsidwa kwa madera, madera omwe amayambika pa pulayimale ndi kulembedwa kuti alembedwa amangopangidwa pa sekondale popanda kufunikira kosintha mafayilo. Katunduyu amathandizidwa ndi gmysql, gpgsql, gsqlite3, godbc ndi lmdb yosungirako backends.
- Pokhazikitsa catalog ya zone, kachidindoyo idakonzedwa kuti igwire ntchito ndi madera ambiri. Posungira madera mu DBMS, chiwerengero cha mafunso a SQL chachepetsedwa kwambiri - mmalo mwa funso lapadera la dera lirilonse, kusankha gulu tsopano kwapangidwa. Kusinthaku kumakhala ndi zotsatira zabwino pakugwira ntchito kwa ma seva omwe amagwiritsa ntchito madera ambiri, ngakhale pamakina omwe sagwiritsa ntchito kalozera wa zone.
- Kukonzanso ndikubwezeretsanso kuthandizira kwa makina osinthira makiyi a GSS-TSIG, omwe adachotsedwapo kale chifukwa cha chiwopsezo komanso zovuta zachitetezo zomwe zingachitike.
- Mukafunsa zolemba za Lua pogwiritsa ntchito TCP, boma la Lua limagwiritsidwanso ntchito, zomwe zimathandizira kwambiri magwiridwe antchito.
- Dongosolo lochokera pa lmdbbackend zida zomangirira ku UUID komanso kuthekera kopanga zozindikiritsa zinthu mwachisawawa.
- Zida zowonjezera ku pdnsutil ndi HTTP APIs kuyang'anira ma seva odziyimira pawokha omwe amagwiritsidwa ntchito kuti azitha kutumizira ndi kukonzanso madera pa ma seva achiwiri a DNS popanda kukonza madera achiwiri pamanja.
- Anawonjezera ntchito yatsopano ya Lua ifurlextup.
- Onjezani zoyeserera zakumbuyo zopangira ndi kutumiza makiyi (key roller).
