Rails with nginx and unicorn beginner issues
Question
Hey guys was wondering if anyone could point out the glaring issue with my overall server organization, nginx config, or unicorn config?
Basically the issue is my requests are going from Nginx, and serving the rails static 404 page, as opposed to the welcome#index page. I feel like the main issue is with my nginx config somehow not properly pointing to my unicorn server.
The only warning I am getting in nginx error log is:
duplicate MIME type "text/html" in /etc/nginx/nginx.conf:68

The problem here is the structure of your application on server, where you should remove the public from within current and the structure should be like this :

I am no expert. But your nginx config appears to be wrong. I am pasting the config I use for my nginx and hope that solves your problem.
upstream unicorn_server{
server unix:/var/webapps/rails-server/current/tmp/sockets/unicorn.sock fail_timeout=0;
}
server{
listen 3000;
root /var/webapps/rails-server/current/public;
location ^~ /assets/{
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri @unicorn_server;
location @unicorn_server{
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn_server;
}
error_page 500 502 503 504 /500.html;
}
Basically I feel the problem lies with your try_files directive. http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files It checks the existence of files in specified order. You have mentioned @app at the end which doesn't match your upstream config. That might be the reason.
