CentOS 6.3 x64 \u00dczerine PowerDNS Kurulumu: Kapsaml\u0131 Bir Rehber<\/h2>\n

Giri\u015f<\/h3>\n

Alan Ad\u0131 Sistemi (DNS), internetin temel yap\u0131 ta\u015flar\u0131ndan biridir. \u0130nsanlar\u0131n hat\u0131rlamas\u0131 kolay alan adlar\u0131n\u0131 (\u00f6rne\u011fin, google.com) makinelerin anlayabilece\u011fi IP adreslerine (\u00f6rne\u011fin, 172.217.160.142) d\u00f6n\u00fc\u015ft\u00fcrerek web sitelerine eri\u015fimi, e-posta g\u00f6nderimini ve di\u011fer internet tabanl\u0131 hizmetlerin \u00e7al\u0131\u015fmas\u0131n\u0131 m\u00fcmk\u00fcn k\u0131lar. G\u00fcvenilir ve y\u00fcksek performansl\u0131 bir DNS sunucusu, herhangi bir a\u011f altyap\u0131s\u0131n\u0131n kritik bir bile\u015fenidir. Bu ba\u011flamda PowerDNS, esnekli\u011fi, mod\u00fcler yap\u0131s\u0131 ve \u00e7e\u015fitli veritaban\u0131 arka u\u00e7lar\u0131n\u0131 desteklemesiyle \u00f6ne \u00e7\u0131kan pop\u00fcler bir a\u00e7\u0131k kaynak DNS sunucusudur.<\/p>\n

Bu makale, CentOS 6.3 x64 i\u015fletim sistemi y\u00fckl\u00fc bir sunucu \u00fczerine PowerDNS Authoritative Server’\u0131n ad\u0131m ad\u0131m nas\u0131l kurulaca\u011f\u0131n\u0131 ve yap\u0131land\u0131r\u0131laca\u011f\u0131n\u0131 ayr\u0131nt\u0131l\u0131 olarak a\u00e7\u0131klamaktad\u0131r. CentOS 6.3 her ne kadar eski bir i\u015fletim sistemi olsa da, bir\u00e7ok eski sistemde hala aktif olarak kullan\u0131lmakta veya belirli proje gereksinimleri nedeniyle tercih edilmektedir. Bu rehber, PowerDNS’i kaynak koddan derleyerek ve MySQL veritaban\u0131 arka ucunu kullanarak kurulumu ger\u00e7ekle\u015ftirecektir. Bu y\u00f6ntem, size en g\u00fcncel PowerDNS s\u00fcr\u00fcm\u00fcn\u00fc (CentOS 6.3 uyumlu olan\u0131) kurma ve yap\u0131land\u0131rma \u00fczerinde tam kontrol sa\u011flar.<\/p>\n

PowerDNS, geleneksel DNS sunucular\u0131ndan (BIND gibi) farkl\u0131 olarak, DNS kay\u0131tlar\u0131n\u0131 dosya tabanl\u0131 sistemler yerine veritabanlar\u0131nda (MySQL, PostgreSQL, SQLite, Oracle, LDAP vb.) saklayabilme yetene\u011fi sunar. Bu, \u00f6zellikle b\u00fcy\u00fck \u00f6l\u00e7ekli ve dinamik DNS ortamlar\u0131 i\u00e7in y\u00f6netim kolayl\u0131\u011f\u0131, otomasyon potansiyeli ve geli\u015fmi\u015f performans avantajlar\u0131 sa\u011flar. Ayr\u0131ca, PowerDNS’in mod\u00fcler mimarisi, DNSSEC deste\u011fi, geli\u015fmi\u015f g\u00fcvenlik \u00f6zellikleri ve geni\u015fletilebilirlik imkanlar\u0131, onu modern DNS ihtiya\u00e7lar\u0131 i\u00e7in cazip bir se\u00e7enek haline getirir.<\/p>\n

Bu kapsaml\u0131 rehberde, CentOS 6.3 sunucunuzu PowerDNS kurulumu i\u00e7in haz\u0131rlamaktan, MySQL veritaban\u0131n\u0131 kurup yap\u0131land\u0131rmaya, PowerDNS’i kaynak koddan derleyip kurmaya, temel yap\u0131land\u0131rma ayarlar\u0131n\u0131 yapmaya, bir init scripti olu\u015fturarak servisi y\u00f6netmeye, g\u00fcvenlik duvar\u0131 ayarlar\u0131n\u0131 d\u00fczenlemeye ve ilk alan ad\u0131n\u0131z\u0131 ekleyerek sistemi test etmeye kadar t\u00fcm ad\u0131mlar\u0131 bulacaks\u0131n\u0131z. Amac\u0131m\u0131z, rehberin sonunda \u00e7al\u0131\u015fan, g\u00fcvenli ve y\u00f6netilebilir bir PowerDNS Authoritative Server’a sahip olman\u0131z\u0131 sa\u011flamakt\u0131r.<\/p>\n

\u00d6n Gereksinimler<\/h3>\n

PowerDNS kurulumuna ba\u015flamadan \u00f6nce a\u015fa\u011f\u0131daki \u00f6n gereksinimlerin kar\u015f\u0131land\u0131\u011f\u0131ndan emin olman\u0131z \u00f6nemlidir:<\/p>\n

CentOS 6.3 x64 \u0130\u015fletim Sistemi<\/h4>\n

Kurulumu yapaca\u011f\u0131n\u0131z, temiz bir CentOS 6.3 x64 i\u015fletim sistemi y\u00fckl\u00fc bir sunucuya ihtiyac\u0131n\u0131z var. Bu sunucunun minimum 1GB RAM ve 20GB disk alan\u0131na sahip olmas\u0131 \u00f6nerilir. Daha b\u00fcy\u00fck ve yo\u011fun DNS trafi\u011fi beklenen ortamlar i\u00e7in bu de\u011ferler art\u0131r\u0131lmal\u0131d\u0131r.<\/p>\n

Root veya Sudo Yetkileri<\/h4>\n

T\u00fcm kurulum ve yap\u0131land\u0131rma ad\u0131mlar\u0131 i\u00e7in root<\/code> kullan\u0131c\u0131s\u0131 olarak oturum a\u00e7man\u0131z veya sudo<\/code> yetkilerine sahip bir kullan\u0131c\u0131 kullanman\u0131z gerekmektedir. Bu rehberdeki komutlar root<\/code> kullan\u0131c\u0131s\u0131 taraf\u0131ndan \u00e7al\u0131\u015ft\u0131r\u0131lacak \u015fekilde yaz\u0131lm\u0131\u015ft\u0131r. E\u011fer sudo<\/code> kullan\u0131yorsan\u0131z, her komutun ba\u015f\u0131na sudo<\/code> eklemeniz gerekecektir.<\/p>\n

\u0130nternet Ba\u011flant\u0131s\u0131<\/h4>\n

Sunucunuzun, gerekli paketleri indirmek ve PowerDNS kaynak kodunu \u00e7ekmek i\u00e7in aktif bir internet ba\u011flant\u0131s\u0131na sahip olmas\u0131 gerekmektedir.<\/p>\n

Temel Linux Komut Sat\u0131r\u0131 Bilgisi<\/h4>\n

Linux komut sat\u0131r\u0131 ve temel metin d\u00fczenleyici (vi\/vim veya nano gibi) kullan\u0131m\u0131 hakk\u0131nda bilgi sahibi olman\u0131z, kurulum s\u00fcrecini daha rahat y\u00f6netmenizi sa\u011flayacakt\u0131r.<\/p>\n

Firewall Ayarlar\u0131<\/h4>\n

DNS hizmeti, varsay\u0131lan olarak 53 numaral\u0131 TCP ve UDP portlar\u0131n\u0131 kullan\u0131r. Sunucunuzun g\u00fcvenlik duvar\u0131n\u0131n (iptables) bu portlardan gelen ba\u011flant\u0131lara izin verecek \u015fekilde yap\u0131land\u0131r\u0131lmas\u0131 gerekecektir. Bu ad\u0131m\u0131 kurulumun ilerleyen a\u015famalar\u0131nda detayl\u0131 olarak ele alaca\u011f\u0131z.<\/p>\n

SELinux Durumu<\/h4>\n

SELinux (Security-Enhanced Linux), CentOS gibi sistemlerde ek bir g\u00fcvenlik katman\u0131 sa\u011flar. Baz\u0131 durumlarda, SELinux politikalar\u0131 PowerDNS’in d\u00fczg\u00fcn \u00e7al\u0131\u015fmas\u0131n\u0131 engelleyebilir. Kurulum s\u0131ras\u0131nda sorun ya\u015fanmamas\u0131 ad\u0131na, SELinux’u ge\u00e7ici olarak devre d\u0131\u015f\u0131 b\u0131rakmak veya izin veren kurallar eklemek gerekebilir. Genellikle, PowerDNS varsay\u0131lan SELinux politikalar\u0131yla \u00e7al\u0131\u015fabilse de, derleme ve servis ba\u015flatma sorunlar\u0131 ya\u015farsan\u0131z bunu kontrol etmeniz faydal\u0131 olacakt\u0131r. SELinux’u ge\u00e7ici olarak devre d\u0131\u015f\u0131 b\u0131rakmak i\u00e7in setenforce 0<\/code> komutunu kullanabilirsiniz. Kal\u0131c\u0131 olarak devre d\u0131\u015f\u0131 b\u0131rakmak i\u00e7in \/etc\/selinux\/config<\/code> dosyas\u0131n\u0131 d\u00fczenlemeniz gerekir. Ancak, g\u00fcvenlik a\u00e7\u0131s\u0131ndan kal\u0131c\u0131 devre d\u0131\u015f\u0131 b\u0131rakma yerine uygun politikalar\u0131n yap\u0131land\u0131r\u0131lmas\u0131 \u00f6nerilir. Bu rehberde, varsay\u0131lan olarak SELinux’un PowerDNS’in \u00e7al\u0131\u015fmas\u0131na engel olmayaca\u011f\u0131 varsay\u0131lm\u0131\u015ft\u0131r.<\/p>\n

G\u00fcncelleme i\u015flemi tamamland\u0131ktan sonra, baz\u0131 \u00e7ekirdek veya sistem bile\u015fenleri g\u00fcncellenmi\u015fse, sunucuyu yeniden ba\u015flatman\u0131z \u00f6nerilir:<\/p>\n

Sonraki Ad\u0131mlar ve \u0130yile\u015ftirmeler:<\/strong><\/p>\n
*   Y\u00fcksek Eri\u015filebilirlik (Redundancy):<\/strong> Tek bir DNS sunucusu, tek hata noktas\u0131 olu\u015fturur. Y\u00fcksek eri\u015filebilirlik sa\u011flamak i\u00e7in en az bir PowerDNS Slave sunucusu kurarak DNS kay\u0131tlar\u0131n\u0131z\u0131n yedeklili\u011fini sa\u011flaman\u0131z \u015fiddetle tavsiye edilir. Bu, bir sunucunun ar\u0131zalanmas\u0131 durumunda hizmet kesintisini \u00f6nleyecektir.
\n*   DNSSEC (Domain Name System Security Extensions):<\/strong> DNSSEC, DNS sorgular\u0131n\u0131n g\u00fcvenli\u011fini art\u0131rmak i\u00e7in dijital imzalar kullan\u0131r. PowerDNS, DNSSEC'i destekler ve alan adlar\u0131n\u0131z i\u00e7in DNSSEC'i etkinle\u015ftirmek, g\u00fcvenlik seviyenizi \u00f6nemli \u00f6l\u00e7\u00fcde art\u0131racakt\u0131r.
\n*   PowerDNS Recursor:<\/strong> E\u011fer sunucunuzun hem yetkili hem de rek\u00fcrsif DNS hizmeti vermesini istiyorsan\u0131z, PowerDNS Recursor'\u0131 ayr\u0131 bir bile\u015fen olarak kurman\u0131z gerekebilir. Yetkili sunucu (Authoritative) sadece kendi alan adlar\u0131 hakk\u0131nda bilgi verirken, rek\u00fcrsif sunucu (Recursor) di\u011fer alan adlar\u0131 hakk\u0131ndaki bilgileri internetten toplay\u0131p istemcilere iletir.
\n*   Web Tabanl\u0131 Y\u00f6netim Aray\u00fcz\u00fc (Poweradmin):<\/strong> PowerDNS kay\u0131tlar\u0131n\u0131 veritaban\u0131 \u00fczerinden do\u011frudan y\u00f6netmek yerine, Poweradmin gibi web tabanl\u0131 aray\u00fczler kullanarak alan ad\u0131 y\u00f6netimini \u00e7ok daha kolay ve g\u00f6rsel hale getirebilirsiniz.
\n*   Performans \u0130zleme:<\/strong> Sunucunuzun performans\u0131n\u0131 ve DNS sorgu y\u00fck\u00fcn\u00fc izlemek i\u00e7in Prometheus, Grafana veya benzeri ara\u00e7lar\u0131 entegre edebilirsiniz. PowerDNS, SNMP ve di\u011fer metrik \u00e7\u0131k\u0131\u015flar\u0131n\u0131 destekler.
\n*   G\u00fcvenlik ve Bak\u0131m:<\/strong> Sunucunuzu d\u00fczenli olarak g\u00fcncel tutun, g\u00fcvenlik duvar\u0131 kurallar\u0131n\u0131z\u0131 g\u00f6zden ge\u00e7irin ve PowerDNS yap\u0131land\u0131rman\u0131z\u0131 periyodik olarak kontrol edin.
