Jenkins Nedir ve Neden \u00d6nemlidir?<\/h2>\n

Modern yaz\u0131l\u0131m geli\u015ftirme s\u00fcre\u00e7lerinde, kod de\u011fi\u015fikliklerinin s\u00fcrekli olarak entegre edildi\u011fi, test edildi\u011fi ve da\u011f\u0131t\u0131ld\u0131\u011f\u0131 bir yakla\u015f\u0131m olan S\u00fcrekli Entegrasyon (CI) ve S\u00fcrekli Da\u011f\u0131t\u0131m (CD) hayati bir rol oynamaktad\u0131r. Jenkins, bu s\u00fcre\u00e7leri otomatikle\u015ftirmek i\u00e7in kullan\u0131lan a\u00e7\u0131k kaynakl\u0131, g\u00fc\u00e7l\u00fc bir otomasyon sunucusudur. Geli\u015ftiricilerin kodlar\u0131n\u0131 birle\u015ftirme s\u0131kl\u0131\u011f\u0131n\u0131 art\u0131rarak hatalar\u0131 erken a\u015famada tespit etmelerine, testleri otomatik \u00e7al\u0131\u015ft\u0131rmalar\u0131na ve yaz\u0131l\u0131m\u0131 daha h\u0131zl\u0131 ve g\u00fcvenilir bir \u015fekilde yay\u0131nlamalar\u0131na olanak tan\u0131r.<\/p>\n

Bu rehberde, CentOS 7 i\u015fletim sistemi \u00fczerinde Jenkins’i ad\u0131m ad\u0131m nas\u0131l kuraca\u011f\u0131n\u0131z\u0131, temel yap\u0131land\u0131rmalar\u0131n\u0131 nas\u0131l yapaca\u011f\u0131n\u0131z\u0131 ve ilk CI\/CD projenizi nas\u0131l olu\u015fturaca\u011f\u0131n\u0131z\u0131 detayl\u0131 bir \u015fekilde \u00f6\u011freneceksiniz.<\/p>\n

Jenkins Kurulumu \u0130\u00e7in \u00d6n Gereksinimler<\/h2>\n

Jenkins’in sorunsuz \u00e7al\u0131\u015fabilmesi i\u00e7in baz\u0131 \u00f6n ko\u015fullar\u0131n yerine getirilmesi gerekmektedir. CentOS 7 sunucunuzda bu ad\u0131mlar\u0131 takip ederek gerekli ortam\u0131 haz\u0131rlayal\u0131m.<\/p>\n

Sistem G\u00fcncellemesi<\/h3>\n

Herhangi bir kuruluma ba\u015flamadan \u00f6nce sistem paketlerini g\u00fcncel tutmak iyi bir uygulamad\u0131r:<\/p>\n

sudo yum update -y\nsudo yum upgrade -y<\/code><\/pre>\n
Java Kurulumu<\/h3>\n
Jenkins, Java tabanl\u0131 bir uygulamad\u0131r ve \u00e7al\u0131\u015fmas\u0131 i\u00e7in Java Sanal Makinesi (JVM) gerektirir. CentOS 7 \u00fczerinde OpenJDK 8’i kurmak i\u00e7in a\u015fa\u011f\u0131daki komutlar\u0131 kullanabilirsiniz:<\/p>\n
sudo yum install java-1.8.0-openjdk-devel -y<\/code><\/pre>\n
Kurulumun ard\u0131ndan Java s\u00fcr\u00fcm\u00fcn\u00fc kontrol edebilirsiniz:<\/p>\n
java -version<\/code><\/pre>\n
\u00c7\u0131kt\u0131 a\u015fa\u011f\u0131daki gibi olmal\u0131d\u0131r:<\/p>\n
openjdk version \"1.8.0_XXX\"\nOpenJDK Runtime Environment (build 1.8.0_XXX-bXX)\nOpenJDK 64-Bit Server VM (build 25.XXX-bXX, mixed mode)<\/code><\/pre>\n
Firewall Ayarlar\u0131<\/h3>\n
Jenkins varsay\u0131lan olarak 8080 portunu kullan\u0131r. Bu porta d\u0131\u015far\u0131dan eri\u015filebilmesi i\u00e7in CentOS 7’nin g\u00fcvenlik duvar\u0131 (firewalld) \u00fczerinde bir kural tan\u0131mlaman\u0131z gerekir:<\/p>\n
sudo firewall-cmd --permanent --add-port=8080\/tcp\nsudo firewall-cmd --reload<\/code><\/pre>\n
Bu komutlar, 8080 portuna TCP trafi\u011fine izin verir ve g\u00fcvenlik duvar\u0131 kurallar\u0131n\u0131 yeniden y\u00fckler.<\/p>\n
Jenkins Kurulumu ve \u0130lk Yap\u0131land\u0131rmas\u0131<\/h2>\n
\u00d6n gereksinimleri tamamlad\u0131ktan sonra Jenkins’i kurmaya ve ilk yap\u0131land\u0131rmas\u0131n\u0131 yapmaya haz\u0131r\u0131z.<\/p>\n
Jenkins Repository Ekleme<\/h3>\n
Jenkins paketlerini CentOS 7’ye kurabilmek i\u00e7in \u00f6ncelikle Jenkins’in kendi YUM deposunu sisteminize eklemeniz gerekir:<\/p>\n
sudo wget -O \/etc\/yum.repos.d\/jenkins.repo https:\/\/pkg.jenkins.io\/redhat-stable\/jenkins.repo\nsudo rpm --import https:\/\/pkg.jenkins.io\/redhat-stable\/jenkins.io.key<\/code><\/pre>\n
Jenkins Kurulumu<\/h3>\n
Depoyu ekledikten sonra Jenkins paketini kurabiliriz:<\/p>\n
sudo yum install jenkins -y<\/code><\/pre>\n
Jenkins Servisini Ba\u015flatma ve Etkinle\u015ftirme<\/h3>\n
Kurulum tamamland\u0131ktan sonra Jenkins servisini ba\u015flat\u0131n ve sistem ba\u015flang\u0131c\u0131nda otomatik olarak ba\u015flamas\u0131 i\u00e7in etkinle\u015ftirin:<\/p>\n
sudo systemctl start jenkins\nsudo systemctl enable jenkins\nsudo systemctl status jenkins<\/code><\/pre>\n
systemctl status jenkins<\/code> komutunun \u00e7\u0131kt\u0131s\u0131nda Jenkins’in active (running)<\/code> oldu\u011funu g\u00f6rmelisiniz.<\/p>\n
Jenkins Web Aray\u00fcz\u00fc ile \u0130lk Yap\u0131land\u0131rma<\/h3>\n
Jenkins servisi \u00e7al\u0131\u015fmaya ba\u015flad\u0131ktan sonra, web taray\u0131c\u0131n\u0131zdan sunucunuzun IP adresi veya alan ad\u0131yla 8080 portundan eri\u015febilirsiniz:<\/p>\n
http:\/\/sizin_sunucu_ip_adresiniz:8080<\/code><\/pre>\n
\u0130lk eri\u015fimde sizden bir ba\u015flang\u0131\u00e7 \u015fifresi isteyecektir. Bu \u015fifreyi a\u015fa\u011f\u0131daki komutla alabilirsiniz:<\/p>\n
sudo cat \/var\/lib\/jenkins\/secrets\/initialAdminPassword<\/code><\/pre>\n
\u00c7\u0131kt\u0131daki \u015fifreyi kopyalay\u0131p Jenkins web aray\u00fcz\u00fcndeki ilgili alana yap\u0131\u015ft\u0131r\u0131n ve “Continue” butonuna t\u0131klay\u0131n.<\/p>\n
Ard\u0131ndan, Jenkins eklentilerini kurma se\u00e7ene\u011fi sunulacakt\u0131r:<\/p>\n

  • Install suggested plugins:<\/strong> \u00c7o\u011fu kullan\u0131c\u0131 i\u00e7in \u00f6nerilen eklentileri kurar. Bu genellikle en iyi ba\u015flang\u0131\u00e7 se\u00e7ene\u011fidir.<\/li>\n
  • Select plugins to install:<\/strong> \u0130htiya\u00e7lar\u0131n\u0131za g\u00f6re eklentileri manuel olarak se\u00e7menize olanak tan\u0131r.<\/li>\n<\/ul>\n
    “Install suggested plugins” se\u00e7ene\u011fini se\u00e7erek devam etmenizi \u00f6neririz. Jenkins gerekli eklentileri indirip kuracakt\u0131r.<\/p>\n
    Eklenti kurulumu tamamland\u0131ktan sonra, ilk y\u00f6netici kullan\u0131c\u0131y\u0131 olu\u015fturman\u0131z istenecektir. Kullan\u0131c\u0131 ad\u0131, parola, tam ad ve e-posta adresi gibi bilgileri girerek bir y\u00f6netici hesab\u0131 olu\u015fturun ve “Save and Finish” butonuna t\u0131klay\u0131n. Son olarak, “Start using Jenkins” butonuna t\u0131klayarak Jenkins kontrol paneline eri\u015febilirsiniz.<\/p>\n

                Jenkins neden varsay\u0131lan olarak 8080 portunu kullan\u0131r?<\/h3>\n
                8080 portu, genellikle web sunucular\u0131 veya uygulama sunucular\u0131 taraf\u0131ndan alternatif bir HTTP portu olarak kullan\u0131l\u0131r. Jenkins de bir web uygulamas\u0131 oldu\u011fu i\u00e7in varsay\u0131lan olarak bu portu kullan\u0131r.

Genellikle hata mesajlar\u0131 burada a\u00e7\u0131k\u00e7a belirtilir.<\/li>\n
                • Ba\u011f\u0131ml\u0131l\u0131klar Eksik:<\/strong> Derleme veya test ad\u0131mlar\u0131 i\u00e7in gerekli olan yaz\u0131l\u0131mlar (Maven, npm, Python, Docker vb.) Jenkins sunucusunda veya agent’ta kurulu olmayabilir.<\/li>\n

                  Jenkins’i HTTPS \u00fczerinden nas\u0131l eri\u015filebilir yapar\u0131m?<\/h3>\n
                  Jenkins’in kendisi do\u011frudan HTTPS sa\u011flamaz. Genellikle bu, bir ters proxy (reverse proxy) sunucusu (\u00f6rne\u011fin Nginx veya Apache) kullan\u0131larak yap\u0131l\u0131r. Ters proxy, istemciden gelen HTTPS isteklerini al\u0131r, \u015fifresini \u00e7\u00f6zer ve iste\u011fi Jenkins’in HTTP portuna (varsay\u0131lan 8080) iletir. Ters proxy sunucusu ayn\u0131 zamanda SSL sertifikalar\u0131n\u0131 y\u00f6netir. Bu yap\u0131land\u0131rma, hem g\u00fcvenlik hem de daha esnek URL y\u00f6netimi sa\u011flar.<\/p>\n
