ruby - How to really set up a Rails 4.2 application in a subdirectory? Using nginx and puma -

first have tried hard long time. have application that's in /home/deploy/app/myapp , want deploy accessed in http://myurl.com/myapp because want have many others on same domain name.

the problem rails default configuration not working should. should put configuration in application.rb or in production.rb or environment variable (rails_relative_url_root) [ http://edgeguides.rubyonrails.org/configuring.html#deploy-to-a-subdirectory-relative-url-root ]. keep getting 404. way worked when put in routes.rb:

rails.application.routes.draw  scope '/myapp' || '/'   root 'home#index'  end end 

it fells wrong. "config.relative_url_root" should work. don't it?

and thing assets still wrong. can't them right. should do?

my nginx config is:

upstream myapp {   server unix:///home/deploy/apps/myapp/shared/tmp/sockets/puma.sock; }  server {   listen 80;   server_name myapp;   keepalive_timeout 5;   access_log /home/deploy/apps/myapp/current/log/production.access.log;   error_log /home/deploy/apps/myapp/current/log/production.error.log info;    if (-f $document_root/maintenance.html) {     rewrite  ^(.*)$  /maintenance.html last;     break;   }    location @myapp {     proxy_pass http://myapp;     proxy_set_header host $host;     proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;     proxy_redirect off;     proxy_set_header x-forwarded-proto $scheme;   }    location /myapp {     alias /home/deploy/apps/myapp/current/public;     try_files $uri @myapp;   } } 

how can fix assets in way nginx server also?

thank you!
