Riak 2 ve Python 3’\u00fcn Ubuntu 14.04 \u00dczerine Kurulumu ve Yap\u0131land\u0131rmas\u0131<\/h2>\n

Giri\u015f<\/h3>\n

G\u00fcn\u00fcm\u00fcz\u00fcn veri odakl\u0131 d\u00fcnyas\u0131nda, y\u00fcksek \u00f6l\u00e7eklenebilirlik, eri\u015filebilirlik ve hata tolerans\u0131 sunan veritaban\u0131 \u00e7\u00f6z\u00fcmleri kritik \u00f6neme sahiptir. Riak, Basho Technologies taraf\u0131ndan geli\u015ftirilen, da\u011f\u0131t\u0131k bir NoSQL anahtar-de\u011fer depolama sistemidir. Dynamo prensiplerine dayal\u0131 olarak tasarlanm\u0131\u015f olan Riak, b\u00fcy\u00fck veri k\u00fcmelerini y\u00f6netmek ve s\u00fcrekli \u00e7al\u0131\u015fma s\u00fcresi sa\u011flamak i\u00e7in m\u00fckemmel bir se\u00e7enektir. Bu makalede, Riak 2’nin Ubuntu 14.04 i\u015fletim sistemi \u00fczerine nas\u0131l kurulaca\u011f\u0131n\u0131, temel yap\u0131land\u0131rmas\u0131n\u0131n nas\u0131l yap\u0131laca\u011f\u0131n\u0131 ve Python 3 programlama dili ile nas\u0131l entegre edilece\u011fini ad\u0131m ad\u0131m inceleyece\u011fiz. Ubuntu 14.04 (Trusty Tahr) eski bir s\u00fcr\u00fcm olsa da, belirli projeler veya eski sistemlerle uyumluluk gereksinimleri nedeniyle hala kullan\u0131l\u0131yor olabilir. Bu rehber, s\u00f6z konusu spesifik ortam i\u00e7in detayl\u0131 bir yol haritas\u0131 sunmaktad\u0131r.<\/p>\n

Riak, \u00f6zellikle IoT (Nesnelerin \u0130nterneti) cihazlar\u0131ndan gelen zaman serisi verileri, oturum y\u00f6netimi, kullan\u0131c\u0131 profilleri ve i\u00e7erik depolama gibi s\u00fcrekli de\u011fi\u015fen ve y\u00fcksek hacimli verilere ihtiya\u00e7 duyan uygulamalar i\u00e7in idealdir. Python 3 ise modern yaz\u0131l\u0131m geli\u015ftirmede yayg\u0131n olarak kullan\u0131lan, g\u00fc\u00e7l\u00fc ve esnek bir dildir. Riak’\u0131n da\u011f\u0131t\u0131k mimarisi ile Python’\u0131n geli\u015ftirici dostu yap\u0131s\u0131n\u0131 birle\u015ftirmek, dayan\u0131kl\u0131 ve \u00f6l\u00e7eklenebilir uygulamalar olu\u015fturman\u0131n kap\u0131lar\u0131n\u0131 a\u00e7ar.<\/p>\n

Bu makale boyunca, Riak 2’nin kurulumundan Python istemcisinin yap\u0131land\u0131rmas\u0131na, temel veri i\u015flemlerinden k\u00fcmeleme kavramlar\u0131na kadar geni\u015f bir yelpazede bilgi edineceksiniz.<\/p>\n

\u00d6n Gereksinimler<\/h3>\n

Riak 2 ve Python 3 kurulumuna ba\u015flamadan \u00f6nce a\u015fa\u011f\u0131daki \u00f6n gereksinimlerin kar\u015f\u0131land\u0131\u011f\u0131ndan emin olun:<\/p>\n

* Ubuntu 14.04 Sunucusu veya Sanal Makinesi:<\/strong> Temiz bir Ubuntu 14.04 (64-bit) kurulumu \u00f6nerilir.
\n* Sudo Yetkileri:<\/strong> Kurulum ve yap\u0131land\u0131rma ad\u0131mlar\u0131 i\u00e7in sudo<\/code> komutunu kullanma yetene\u011fi.
\n* \u0130nternet Ba\u011flant\u0131s\u0131:<\/strong> Gerekli paketleri indirmek i\u00e7in aktif bir internet ba\u011flant\u0131s\u0131.

Riak 2 Kurulumu<\/h3>\n

Riak 2’nin Ubuntu 14.04 \u00fczerine kurulumu, Basho’nun resmi APT deposunu kullanarak yap\u0131l\u0131r. Bu, paket y\u00f6netimini kolayla\u015ft\u0131r\u0131r ve ba\u011f\u0131ml\u0131l\u0131klar\u0131n otomatik olarak \u00e7\u00f6z\u00fclmesini sa\u011flar.<\/p>\n

Sistem G\u00fcncellemesi<\/h4>\n

Kuruluma ba\u015flamadan \u00f6nce sistem paket listesini g\u00fcncellemek ve mevcut paketleri y\u00fckseltmek iyi bir uygulamad\u0131r. Bu, olas\u0131 ba\u011f\u0131ml\u0131l\u0131k sorunlar\u0131n\u0131 \u00f6nlemeye yard\u0131mc\u0131 olur.<\/p>\n

sudo apt-get update\nsudo apt-get upgrade -y<\/code><\/pre>\n
Gerekli Ba\u011f\u0131ml\u0131l\u0131klar\u0131n Kurulumu<\/h4>\n
Riak deposunu eklemek i\u00e7in curl<\/code> ve apt-transport-https<\/code> gibi baz\u0131 temel ara\u00e7lara ihtiyac\u0131m\u0131z olabilir.<\/p>\n
sudo apt-get install -y curl apt-transport-https<\/code><\/pre>\n
Riak Repository Ekleme<\/h4>\n
Basho, Riak paketlerini kendi \u00f6zel deposu \u00fczerinden sunar. Bu depoyu sisteminize eklemek i\u00e7in a\u015fa\u011f\u0131daki komutu kullan\u0131n:<\/p>\n
curl -s https:\/\/packagecloud.io\/install\/repositories\/basho\/riak\/script.deb.sh | sudo bash<\/code><\/pre>\n
Bu komut, Basho’nun genel anahtar\u0131n\u0131 sisteme ekler ve \/etc\/apt\/sources.list.d\/basho_riak.list<\/code> dosyas\u0131na Riak deposu URL’sini yazar. Komutun \u00e7\u0131kt\u0131s\u0131n\u0131 kontrol ederek i\u015flemin ba\u015far\u0131l\u0131 olup olmad\u0131\u011f\u0131n\u0131 teyit edebilirsiniz. Bu ad\u0131m tamamland\u0131ktan sonra, APT paket listesini tekrar g\u00fcncellemeniz gerekir:<\/p>\n
sudo apt-get update<\/code><\/pre>\n
Riak Kurulumu<\/h4>\n
Depo eklendikten ve paket listesi g\u00fcncellendikten sonra Riak 2’yi kurabiliriz. Ubuntu 14.04 i\u00e7in Riak 2’nin son kararl\u0131 s\u00fcr\u00fcm\u00fc olan 2.2.3’\u00fc belirtmek, olas\u0131 uyumluluk sorunlar\u0131n\u0131 \u00f6nlemek ad\u0131na iyi bir yakla\u015f\u0131md\u0131r.<\/p>\n

Bu komut, Riak 2.2.3 s\u00fcr\u00fcm\u00fcn\u00fc ve t\u00fcm ba\u011f\u0131ml\u0131l\u0131klar\u0131n\u0131 sisteminize kuracakt\u0131r. Kurulum tamamland\u0131ktan sonra, Riak’\u0131n versiyonunu kontrol ederek ba\u015far\u0131l\u0131 olup olmad\u0131\u011f\u0131n\u0131 do\u011frulayabilirsiniz:<\/p>\n

Hen\u00fcz yap\u0131land\u0131rma yapmad\u0131\u011f\u0131m\u0131z i\u00e7in tam olarak \u00e7al\u0131\u015f\u0131r durumda olmayabilir, ancak komutun tan\u0131nd\u0131\u011f\u0131n\u0131 g\u00f6rmek yeterlidir.<\/p>\n
