how to configure use of custom http error pages in rails app on nginx + passenger?

[Rafael Revi]

Hello all,

I'd like to have nginx+passenger show the custom (Default) error pages when a HTTP 500 error occurs in my app.

I am running a rails 2.3 app on nginx 1.2 with passenger 3.0.7

Here is my nginx config file:

#user  nobody;
worker_processes  16;


error_log  /opt/nginx/logs/error.log  info;


pid        /opt/nginx/logs/nginx.pid;
worker_rlimit_nofile 32768;


events {
    worker_connections  2048;
}




http {
    passenger_root /usr/lib/ruby/gems/1.8/gems/passenger-3.0.7;
    passenger_ruby /usr/bin/ruby;


    include       mime.types;
    default_type  application/octet-stream;


    #access_log  /opt/nginx/logs/access.log  main;


    sendfile        on;
    #tcp_nopush     on;


    server {
        listen 80;
        server_name localhost;
        root /var/www/dashboard/current/public;
        passenger_enabled on;
        passenger_min_instances 1;
#       listen 443;
#       ssl on;
#       ssl_certificate /opt/nginx/conf/server.crt;
#       ssl_certificate_key /opt/nginx/conf/server.key;


        # Rails error pages
        error_page 500 502 503 504 /500.html;
        location = /500.html {
            root /var/www/dashboard/current/public;
        }
    }
}

In my dev env, app running on webrick, when the app generate a http 500 error I get the custom error page just fine.Any idea why the difference?

Thanks
