Sistem G\u00fcncelleme ve Temel Ara\u00e7lar\u0131n Kurulumu<\/h3>\n

Kuruluma ba\u015flamadan \u00f6nce sisteminizin g\u00fcncel oldu\u011fundan ve gerekli temel ara\u00e7lar\u0131n y\u00fckl\u00fc oldu\u011fundan emin olal\u0131m.<\/p>\n

Sistemi G\u00fcncelleme<\/h4>\n

VPS’nize SSH ile ba\u011fland\u0131ktan sonra, paket listelerini g\u00fcncelleyin ve y\u00fckl\u00fc paketleri y\u00fckseltin:<\/p>\n

sudo apt update\nsudo apt upgrade -y<\/code><\/pre>\n
Bu komutlar, sisteminizin en son g\u00fcvenlik yamalar\u0131na ve yaz\u0131l\u0131m g\u00fcncellemelerine sahip olmas\u0131n\u0131 sa\u011flar.<\/p>\n
Gerekli Yard\u0131mc\u0131 Programlar\u0131n Kurulumu<\/h4>\n
Elasticsearch deposunu eklemek ve paketleri indirmek i\u00e7in curl<\/code>, wget<\/code> ve apt-transport-https<\/code> gibi baz\u0131 yard\u0131mc\u0131 programlara ihtiyac\u0131m\u0131z olacak.<\/p>\n
sudo apt install -y curl wget apt-transport-https<\/code><\/pre>\n
Java (OpenJDK) Kurulumu<\/h3>\n
Elasticsearch, Java sanal makinesi (JVM) \u00fczerinde \u00e7al\u0131\u015ft\u0131\u011f\u0131 i\u00e7in sisteminizde uyumlu bir Java s\u00fcr\u00fcm\u00fcn\u00fcn y\u00fckl\u00fc olmas\u0131 gerekir. Elasticsearch 8.x serisi, OpenJDK 17 ile uyumludur ve bu s\u00fcr\u00fcm \u00f6nerilir.<\/p>\n
OpenJDK 17 Kurulumu<\/h4>\n
A\u015fa\u011f\u0131daki komutla OpenJDK 17’yi kolayca kurabilirsiniz:<\/p>\n
sudo apt install -y openjdk-17-jdk<\/code><\/pre>\n
Kurulum tamamland\u0131ktan sonra, Java s\u00fcr\u00fcm\u00fcn\u00fc do\u011frulayabilirsiniz:<\/p>\n
java -version<\/code><\/pre>\n
\u00c7\u0131kt\u0131, openjdk version \"17.0.x\"<\/code> benzeri bir \u015fey olmal\u0131d\u0131r.<\/p>\n
JAVA_HOME Ortam De\u011fi\u015fkenini Ayarlama (\u0130ste\u011fe Ba\u011fl\u0131 ama \u00d6nerilir)<\/h4>\n
Baz\u0131 uygulamalar veya betikler JAVA_HOME<\/code> ortam de\u011fi\u015fkeninin ayarlanm\u0131\u015f olmas\u0131n\u0131 bekleyebilir. Bu, Java’n\u0131n y\u00fckl\u00fc oldu\u011fu dizini g\u00f6sterir.<\/p>\n
\u00d6ncelikle Java’n\u0131n tam yolunu bulal\u0131m:<\/p>\n
sudo update-alternatives --config java<\/code><\/pre>\n
Bu komut, sisteminizdeki Java kurulumlar\u0131n\u0131 listeler ve size yolunu g\u00f6sterir (genellikle \/usr\/lib\/jvm\/java-17-openjdk-amd64\/bin\/java<\/code>). Bizim ihtiyac\u0131m\u0131z olan, bin<\/code> dizininin bir \u00fcst dizinidir.<\/p>\n
\u015eimdi, JAVA_HOME<\/code> ortam de\u011fi\u015fkenini kal\u0131c\u0131 olarak ayarlayabiliriz. Bunun i\u00e7in \/etc\/environment<\/code> dosyas\u0131n\u0131 d\u00fczenlemek iyi bir y\u00f6ntemdir:<\/p>\n
sudo nano \/etc\/environment<\/code><\/pre>\n
Dosyan\u0131n sonuna a\u015fa\u011f\u0131daki sat\u0131r\u0131 ekleyin (yolu kendi sisteminizdeki yola g\u00f6re ayarlay\u0131n):<\/p>\n
JAVA_HOME=\"\/usr\/lib\/jvm\/java-17-openjdk-amd64\"<\/code><\/pre>\n
Kaydedip \u00e7\u0131kt\u0131ktan sonra, de\u011fi\u015fikliklerin etkili olmas\u0131 i\u00e7in oturumu yeniden y\u00fckleyin veya a\u015fa\u011f\u0131daki komutu \u00e7al\u0131\u015ft\u0131r\u0131n:<\/p>\n

Elasticsearch Kurulumu<\/h3>\n
Elasticsearch’\u0131 resmi Elastic deposundan kurmak en kolay ve \u00f6nerilen y\u00f6ntemdir. Bu sayede g\u00fcncellemeleri kolayca y\u00f6netebilirsiniz.<\/p>\n
Elastic GPG Anahtar\u0131n\u0131 ve Depoyu Ekleme<\/h4>\n
Elasticsearch paketlerinin do\u011frulu\u011funu sa\u011flamak i\u00e7in Elastic’in genel anahtar\u0131n\u0131 sisteminize eklemeniz gerekir:<\/p>\n
wget -qO - https:\/\/artifacts.elastic.co\/GPG-KEY-elasticsearch | sudo gpg --dearmor -o \/usr\/share\/keyrings\/elasticsearch-keyring.gpg<\/code><\/pre>\n
Bu komut, Elastic GPG anahtar\u0131n\u0131 indirir ve apt<\/code> taraf\u0131ndan g\u00fcvenilir anahtar olarak kullan\u0131lmak \u00fczere elasticsearch-keyring.gpg<\/code> dosyas\u0131na kaydeder.<\/p>\n
\u015eimdi, Elastic deposunu apt<\/code> kaynak listenize ekleyin. Bu rehberde, Elasticsearch 8.x serisini kuraca\u011f\u0131m\u0131z i\u00e7in ilgili depoyu ekliyoruz:<\/p>\n
echo \"deb [signed-by=\/usr\/share\/keyrings\/elasticsearch-keyring.gpg] https:\/\/artifacts.elastic.co\/packages\/8.x\/apt stable main\" | sudo tee \/etc\/apt\/sources.list.d\/elastic-8.x.list<\/code><\/pre>\n
Depoyu ekledikten sonra, yeni paketleri tan\u0131mak i\u00e7in apt<\/code> paket listesini g\u00fcncelleyin:<\/p>\n
sudo apt update<\/code><\/pre>\n
Elasticsearch Paketini Kurma<\/h4>\n
Art\u0131k Elasticsearch paketini kurmaya haz\u0131rs\u0131n\u0131z:<\/p>\n
sudo apt install elasticsearch<\/code><\/pre>\n
Kurulum tamamland\u0131\u011f\u0131nda, Elasticsearch servisi otomatik olarak ba\u015flar ve sistem ba\u015flang\u0131c\u0131nda etkinle\u015ftirilir.<\/p>\n
Elasticsearch Yap\u0131land\u0131rmas\u0131<\/h3>\n
Elasticsearch’\u0131n varsay\u0131lan yap\u0131land\u0131rmas\u0131 genellikle tek bir d\u00fc\u011f\u00fcm i\u00e7in yeterli de\u011fildir veya \u00fcretim ortamlar\u0131 i\u00e7in optimize edilmemi\u015ftir.

\n    *   0.0.0.0<\/code>: T\u00fcm a\u011f aray\u00fczlerinde dinler (VPS i\u00e7in d\u0131\u015far\u0131dan eri\u015fime izin vermek istiyorsan\u0131z bu gereklidir).
\n    *   Belirli bir IP adresi: Sadece o IP adresinde dinler.<\/p>\n
    VPS’nizin d\u0131\u015far\u0131dan eri\u015filebilir olmas\u0131n\u0131 istiyorsan\u0131z, genellikle 0.0.0.0<\/code> olarak ayarlaman\u0131z gerekir. Ancak g\u00fcvenlik a\u00e7\u0131s\u0131ndan, sadece belirli IP adreslerinden eri\u015fime izin vermek daha iyidir. \u015eimdilik 0.0.0.0<\/code> olarak ayarlayal\u0131m, g\u00fcvenlik duvar\u0131 ile eri\u015fimi k\u0131s\u0131tlayaca\u011f\u0131z.<\/p>\n

    Bu ayarlar genellikle varsay\u0131lan olarak gelir ve de\u011fi\u015ftirmeniz gerekmez. Elasticsearch 8.x, TLS\/SSL \u015fifrelemesini ve kimlik do\u011frulamas\u0131n\u0131 varsay\u0131lan olarak etkinle\u015ftirir.<\/p>\n
Ayarlar\u0131 kaydettikten sonra (Ctrl+X<\/code>, Y<\/code>, Enter<\/code>), Elasticsearch servisini yeniden ba\u015flatman\u0131z gerekir.<\/p>\n
Bellek Ayarlar\u0131 (JVM Options)<\/h4>\n
Elasticsearch performans\u0131n\u0131 etkileyen en \u00f6nemli fakt\u00f6rlerden biri JVM bellek tahsisidir. Bu ayarlar \/etc\/elasticsearch\/jvm.options<\/code> dosyas\u0131nda bulunur.<\/p>\n
sudo nano \/etc\/elasticsearch\/jvm.options<\/code><\/pre>\n
Burada Xms<\/code> ve Xmx<\/code> parametreleri, JVM’ye tahsis edilecek ba\u015flang\u0131\u00e7 ve maksimum heap belle\u011fini belirler. Genellikle, bu iki de\u011ferin e\u015fit ayarlanmas\u0131 \u00f6nerilir. Kural olarak, sunucunuzdaki toplam RAM’in yar\u0131s\u0131 kadar bellek tahsis etmelisiniz, ancak 32 GB’\u0131 ge\u00e7memelisiniz. \u00d6rne\u011fin, 4 GB RAM’e sahip bir VPS i\u00e7in 2 GB tahsis edebilirsiniz:<\/p>\n
