inanzzz | Capistrano ile uygulama yükleme işlemine mahsus bir kullanıcı yaratıp kullanmak

Bu örneğimizde, capistrano ile deployment sunucusundan uygulamamızı yeni yaratacağımız inanzzz kullanıcısı ile production sunucusuna yükleyeceğiz. Bu kullanıcı her iki sunucuda da tanımlı olacak ve production sunucusundaki yükleme yapılacak olan klasöründe sahibi olacak.

Ön bilgi

Uygulamamızın ismi football.

Deployment sunucusu

IP adres 192.168.99.30.

Uygulamanın tutulduğu yer /projects klasörüdür yani sonuç olarak /projects/football gibi görünecek.

Kullanıcı inanzzz sistemde tanımlı olacak.

Production sunucusu

IP adres 192.168.99.50.

Uygulama /srv/www klasörüne yüklenecek yani sonuç olarak /srv/www/{capistrano specific folder} gibi görünecek.

Sistemde ayrıca yükleme ile ilgili geçici bilgileri tutacak olan /tmp/capistrano klasörü bulunacak.

Kullanıcı inanzzz sistemde tanımlı olacak ve yükleme yapılacak olan /srv klasörününde sahibi olacak.

Deployment sunucusu

Eğer isterseniz kullanabileceğiniz vagrant dosyalarınıda ekliyorum.

Kullanıcıyı yetkilendirme

Eğer bu işlemi deployment sunucusu üzerinde yapmazsanız, uygulamanızı production sunucusuna yüklerken, her zaman bu kullanıcının şifresini girmeniz gerekecek.

inanzzz@deploy:~$ cat ~/.ssh/id_rsa.pub | ssh inanzzz@192.168.99.50 'cat >> /home/inanzzz/.ssh/authorized_keys'
