¿Rails 4 ejemplo de despliegue API para Amazon EC2 usando Capistrano 3, Nginx, Puma, GitHub y RVM?
amazon-ec2 ruby-on-rails-4 (2)
Aumentaré mi respuesta si se solicita, pero como esto es bastante simple, solo te haré una lista. Básicamente, con Capistrano 3 y Puma 2.6 esto es suficiente para que empieces:
- Agrega
pumaaGemfileen el grupo deproduction. - Requerir
''capistrano/puma''desdeCapfile. - Configure cualquier opción de puma en
config/deploy.rbsi es necesario. - Ejecute
cap puma:configpara copiar el archivo de configuración de puma en el servidor. - Ejecutar
cap <stage> deploy. - Configure
nginx''s upstream a la ruta del socket especificada en la configuración de Puma del servidor. - Reinicie
nginx.
Tengo un proyecto Rails 4 API en GitHub, y estoy intentando implementarlo desde mi MacBook Pro usando Capistrano 3 o dos instancias de Amazon AWS EC2 Ubuntu usando claves SSH: una es la aplicación / servidor web, y la otra es PostgreSQL servidor de base de datos. La aplicación / servidor web tiene el último Ruby 2 vía RVM, y servirá la API con Nginx / Puma . Nginx alojará múltiples sitios, uno de los cuales es esta API. Estas son las gemas relevantes que estoy usando:
- gema ''capistrano'', ''~> 3.0.0''
- gemas ''capistrano-rails''
- gema ''capistrano-bundler''
- gema ''capistrano-rvm'', ''~> 0.0.2''
- gema ''capistrano-puma'', github: "seuros / capistrano-puma"
Hasta ahora, no he encontrado un ejemplo completo de configuración de Capistrano 3 que use Puma , pero por más importantes que estas dos gemas sean para la comunidad de Rails, estoy seguro de que debe haber un repositorio de Rails en funcionamiento en alguna parte de GitHub que incluya estos.
Ya he pasado por la documentación oficial de Capistrano 3. Tengo problemas con las diferencias entre Capistrano 2 y Capistrano 3, y me gustaría ver un ejemplo completo de Capistrano 3 para entender las diferencias. Idealmente, estoy buscando un repositorio de código abierto de GitHub que tenga todos los archivos de configuración completados ( Capistrano 3 , Puma , Nginx ) y trabajo al que pueda hacer referencia.
¡Gracias!
Esta pregunta es bastante antigua, pero tengo exactamente la misma configuración: Capistrano 3, Puma y nginx, así que creo que todavía puede ayudar a alguien, especialmente porque ahora Puma es el predeterminado para Rails 5. Mi proyecto no es de código abierto, así que no puedo apuntar a un repositorio público de Github, pero esta es mi configuración completa de Capistrano para que cualquiera pueda echarle un vistazo. Ha funcionado impecablemente durante meses.
Para iniciar Puma correctamente en el servidor de producción al reiniciar EC2 / crear una nueva instancia, mira mi respuesta aquí:
El reinicio de Puma falla al reiniciarse usando EC2 + Rails + Nginx + Capistrano

Configuración del servidor Nginx:
# etc / nginx / sites-enabled / default
# You may add here your
# server {
# ...
# }
# statements for each of your virtual hosts to this file
##
# You should look at the following URL''s in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
