When the Sinatra application errors out (returns 500), I'd like to serve a static page, rather than the default "Internal Server Error". I have the following nginx configuration: server { listen 80 default; server_name *.example.com; root /home/deploy/www-frontend/current/public; location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 5; proxy_read_timeout 240; proxy_pass http://127.0.0.1:4701/; } error_page 500 502 503 504 /50x.html; } The error_page directive

With the above config file, and service nginx reload, the page I receive on error is still the same "Internal Server Error".

By default, nginx will return whatever the proxy server returns regardless of http status code. What you're looking for is proxy_intercept_errors This directive decides if nginx will intercept responses with HTTP status codes of 400 and higher. By default all responses will be sent as-is from the proxied server. If you set this to on then nginx will intercept status codes that are explicitly handled by an error_page directive. Responses with status codes that do not match an error_page directive will be sent as-is from the proxied server. share|improve this answer answered Jan 3 '12 at 16:48 Stephen Emslie 4,26741724 1 I knew it was a question of RTFM.

What I try now to accomplish is to fallback to a local error page in case the service becomes unavailable. My current configuration is server { listen 80; server_name ""; location / { proxy_pass http://127.0.0.1:9080; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 1; proxy_next_upstream error timeout http_500 http_502 http_503 http_504 http_404; proxy_intercept_errors on; } error_page 501 502 503 http://serverfault.com/questions/511109/nginx-local-fallback-error-page-if-proxy-destination-is-unavailable @maintenance; location @maintenance { root /locust/www/fallback/htdocs; index index.html index.htm; } } Proxying works, but as soon as I make my service on 9080 unavailable the index.html of my maintenance location is NOT displayed. Any suggestions on what is wrong with this config? nginx proxy share|improve this question asked May 27 '13 at 8:55 stpn108 2241510 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted Actually, I only had to slightly modify your config: error_page 501 502 503 /500.html; location = /500.html { root /locust/www/fallback/htdocs; } and obviously rename the index.html you want to present to 500.html. share|improve this answer edited Dec 6 '13 at 17:49 Holger Just 3,0651921 answered Dec 6 '13 at 17:28 nutz 8612 Using this approach, what happens when the application running on the proxy_pass throws a 501, 502, or 503? Some applications (like Django) handle their own 50x errors so they can have custom error pages. Will the approach here trump the application generated 50x error pages with the Nginx 500.html page? –Joe J Dec 6 '15 at 20:28 I haven't tested it, but I'm 99% certain, that exactly those errors will display the /500.html . The idea is, that when nginx is getting 501 502 503 from the proxied server, it will display /500.html. The proxied server being django. –nutz Dec 8
App Store Developer Blog Community Blog Developer Tools Support Start For Free How it works: nginx and error pages Hans van Kranenburg on December 26, 2014 Share: In https://www.mendix.com/blog/works-nginx-error-pages/ the week before christmas, we released a nice little extension to our hosting http://www.mjcblog.net/2011/08/nginx-custom-maintenance-page-without-redirects/ platform: It’s now possible to use customized error pages for an application. This blog post will show how web server configuration for applications is done at Mendix, and how this additional feature is implemented, on top of it. If you’re only interested in how to use the custom error page error page feature, and not in how it’s built, read the custom error pages blog post on the corporate tech blog. Green Monsters! If you’re using or maintaining a Mendix application that runs in the Mendix hosting environment, you might have seen them occasionally… The green monsters, running around, eating computers and modems. While we often call them “the green monsters”, these animals are actually nginx reverse proxy called TumblBeasts and were created by The Oatmeal as a gift for Tumblr to use in their error pages. Unfortunately, Tumblr stopped using them after a while, and the creator of them told whoever would want to could use the images. Here’s the most famous page of a set of pages that we’ll discuss in a bit. It’s the page that is shown when a deployed application is stopped: Let’s dive in… Actually, four different green monsters pages currently exist, containing different text, shown in different occasions. In order to understand why, and what they mean, let’s have a look at a simplified view on the web server configuration we use to serve applications over HTTPs to the world: The front facing web server listens on the actual public IP address where your application url points at, and directly handles all browser connections for multiple different applications. The front facing web server knows about every existing application url attached to running applications, and knows where they are running in the internal network behind it. The appnode web server is an nginx instance that is running on the applicati
have nginx respond with the default "502 Bad Gateway" page, we replace it with our own maintenance page. Additionally, we also need to make sure our maintenance page does not redirect the user so their requested URI stays the same. That way when the upstream server is back online, a simple refresh will take the user to their originally requested page. Below is the configuration for our maintenance page: error_page 502 =200 @maintenance; location @maintenance { root /path/to/maintenance; try_files $uri $uri/ /index.html =503; } There are a lot of things going on in this configuration. First off, we are using a named location with an error_page directive to "catch" the 502 error. Secondly, the =200 in this directive is used to set the response code to 200. This is done so browsers properly render the page as well as any CSS or images that are included. Finally, we use the try_files directive in order to first try and serve the requested file (for CSS and images). If these files are not found, it will then try and serve an index.html file. If for some reason index.html is not available, we fallback to the default 503 error page which is more appropriate than the 502 page.
