Nginx 404 Error
Introduction Nginx is a high performance web server capable of serving content with flexibility and power. When designing your web pages, it is often helpful to customize every piece of content that your users will see. This includes error pages for when they request content that is not available. In this guide, we'll demonstrate how to configure Nginx to
Nginx Custom 404 Page
use custom error pages on Ubuntu 14.04. Prerequisites To get started on with this guide, you will need a non-root user with sudo privileges. You can set up a user of this type by following along with our initial set up guide for Ubuntu 14.04. You will also need to have Nginx installed on your system. Learn how to set this up by following this guide. When you have completed the above steps, continue with this guide. Creating Your Custom Error Pages We will create a few custom error pages for demonstration purposes, but your custom pages will obviously be different. We will put our custom error pages in the /usr/share/nginx/html directory where Ubuntu's Nginx sets its default document root. We'll make a page for 404 errors called custom_404.html and one for general 500-level errors called custom_50x.html. You can use the following lines if you are just testing. Otherwise, put your own content in these locations:
- echo "
Error 404: Not found :-(
" | sudo tee /usr/share/nginx/html/custom_404.html so that error pages work for all types of requests, not justGET. Normally, 404 and 500 error pages are static HTML files that live in the public directory of a Rails nginx default error page application. These are boring, minimally-styled pages that don’t get the same treatment

as the rest of the app. This tutorial shows you how to move error pages into your Rails app nginx default 404 page as dynamic views that benefit from application styles, layouts, and viewhelpers. tl;dr – jump to the Rails code and the Capistrano bonustip Why are dynamic error pages paticularly handy in Rails4? https://www.digitalocean.com/community/tutorials/how-to-configure-nginx-to-use-custom-error-pages-on-ubuntu-14-04 Starting with Rails 4, the production asset pipeline no longer generates filenames without cache-busters. This means that referencing /assets/application.css in your static public/404.html page won’t work in a Rails 4 app! The file will not exist in the production environment. The only way to reliably reference your application stylesheet is to use the stylesheet_link_taghelper. But error pages are static HTML pages; they can’t https://mattbrictson.com/dynamic-rails-error-pages use helpers, right? If you want nice-looking error pages in Rails 4, here are youroptions: Option 1: No external styles. Don’t reference your application stylesheet at all. Instead, use simple, static error pages with the necessary minimal CSS copied and pasted into each HTML file. This is the solution that ships withRails. Works for simple apps that don’t need custom-branded errorpages. Option 2: Monkey patch. Use static error pages and point to /assets/application.css for styling. Then, monkey-patch Rails to restore the pre-Rails 4 behavior so that the asset pipeline generates non-cache-busted filenames in production. Make sure not to send far-future expires headers for thesefiles! Easiest option for migrating an existing app to Rails4. Option 3: Dynamic. Use dynamic view templates (ERB) for error pages, and take advantage of the stylesheet_link_tag helper to get the right cache-busted filename. Error pages can use your application styles. Be careful, though: if your Rails app is down, your error pages can’t beaccessed. Most flexible option. This is the solution I describebelow. OK, so you’re ready to set up dynamic error pages in a Rails 4 app? Here’s how to do

Basically, what I'm trying to do is serve certain files for a server under the root for that server, e.g. /var/www/someserver.com/robots.txt. If that file does not exist, I want nginx to go to the "default", i.e. /var/www/default/robots.txt. This is the basic gist of how I have that (successfully) configured: server { ... root /var/www/someserver.com; location ~* ^/(robots\.txt)$ { error_page 404 = @default; } location @default { root /var/www/default; } } That works great. I'm trying to do the same for error pages, and I'm not able to make that happen though: server { ... root /var/www/someserver.com; error_page 404 /404.html; location ~* ^/(404\.html)$ { error_page 404 = @default; } location @default { root /var/www/default; } } Note that this "works" in the sense that if you visit someserver.com/404.html, it will first try to load /var/www/someserver.com/404.html and then fall back to /var/www/default/404.html if that's not found. However, if you visit someserver.com/blahblah, it only shows the 404 page if it's set in /var/www/someserver.com/. It does not fall back to the default directory if that file doesn't exist. Anyhow, you can probably what I was trying to accomplish (that's why I included the first working example). Any ideas? Edit: Based on Martin F's answer, this is what I ended up putting together: # Doesn't work when error page is returned on a POST request server { ... root /var/www/someserver.com; error_page 404 = @notfound; error_page 500 502 504 = @server_error; error_page 503 = @maintenance; location @notfound { try_files /404.html /../default/404.html =404; } location @server_error { try_files /500.html /../default/500.html =500; } location @ma
