Hi,

Please add nginx with puma configuration for production.

Thanks.

This is the config that I use for nginx/puma. The puma.rb is within the rails application's config folder.

nginx.conf

upstream backend {
  server unix:///var/run/puma/my_app.sock;
}
server {
  listen 80;
  server_name _ localhost;
  access_log  /var/log/nginx/access.log main;
  error_log /var/log/nginx/error.log;
  large_client_header_buffers 8 32k;
  root /var/app/current/public;
  location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_buffers 8 32k;
    proxy_buffer_size 64k;
    proxy_pass http://backend;
    proxy_redirect off;
    # enables WS support
    location /cable {
      proxy_pass http://backend;
      proxy_http_version 1.1;
      proxy_set_header Upgrade "websocket";
      proxy_set_header Connection "Upgrade";
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
  }
  
  location /assets {
    alias /var/app/current/public/assets;
    gzip_static on;
    gzip on;
    expires max;
    add_header Cache-Control public;
  }
  location /public {
    alias /var/app/current/public;
    gzip_static on;
    gzip on;
    expires max;
    add_header Cache-Control public;
  }
}

config/puma.rb

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
threads     2, threads_count
port        ENV.fetch("PORT") { 3000 }
environment ENV.fetch("RAILS_ENV") { "development" }
workers     ENV.fetch("WEB_CONCURRENCY") { 2 }
preload_app!
before_fork do
  ActiveRecord::Base.connection_pool.disconnect! if defined?(ActiveRecord)
end
on_worker_boot do
  ActiveRecord::Base.establish_connection if defined?(ActiveRecord)
end
plugin :tmp_restart

Thanks, one more thing is don't we need daemonize to run puma in background and environment is pointing to "development" in pumb.rb but it should be "production".

Hi, Have you used capistrano for app deployment ? Please throw some light on it. Thanks.

What would be configuration/tuning for postgresql on production ?

I don't do too much with PostgreSQL, but is there specific cases that you're looking for?

No, I am looking for generic configuration tuning for on-premise server.

Any reasoning on rvm over rbenv?

it is a personal preference. Ive been using it for years without problems so I have not had a reason to change.
