Problem with nginx + unicorn. Why is only the main page working?

Question

Nginx

Hello. There is an application on Rails 3.2.2 (running on a production server). You need to make changes to it + later install it on the client servers. I, in accordance with the parameters of the main server, set up the environment of the new server, copied the application and its database (mysql). The application starts, but only the main page works, when you go somewhere - Routing error (although everything is in the rake routes listing). Also, there is no access to assets on the server. The server configs are the same (except for the server name in nginx.conf).
nginx.conf

#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

  $redis = Redis.connect
end

Tell me which way to dig?

Answer 1

The problem was solved after rake assets:precompile

Answer 2

Dig towards user rights. Who runs nginx? Who is the app from? What are the rights to assets?

Answer 3

Most likely, the problem is that you have upstream e-script_upstream, and then a block is defined in the config location @app {}, and it’s not at all proxy_pass http://site_upstream;clear where in it.
Also, try location ^~ /assets/insteadlocation ~ ^/assets/
