Nginx 404 Error
votes up vote 25 down vote accepted It's similar to setting up the custom 404 pages.

I tried these slightly different instructions and got it working. –BigglesZX Aug 26 '12 at 10:35 1 Confirmed. That doesn't work. This shouldn't be the correct answer. –PKHunter Aug 2 '14 at 1:32 What file do you need to add these lines to?

Goal: when upstream server_api is down (say, its worker processes has crashed), I want nginx to display my custom error page. My configuration: location http://serverfault.com/questions/680470/catch-upstream-down-502-errors-and-display-custom-error-page @server { proxy_pass http://server_api; proxy_redirect off; ... proxy_intercept_errors on; error_page 502 /error-502.html; } error_page 502 /error-502.html; location = /error-502.html { internal; root /srv/my-server/html; } My steps: I have my static error page at /srv/my-server/html/error-502.html ready, same permission and owners as other static assets. I have stopped my upstream service, and see [error] 2359#0: *25 connect() failed (111: Connection refused) while connecting to upstream appearing in logs. Now I try to make my custom error page show up for 502 errors. I have tried setting error_page at both or either server or location block. I have tried error_page with proxy_intercept_errors on in the location or server block; None of them appear to persuade nginx to display my error page. Why not?

check my servers for upgrades on a regular basis and when I noticed yesterday that PHP was upgraded to version 5.5.12, I backed up everything of course (backup guide) and decided to upgrade which can easily be done with sudo apt-get dist-upgrade. Unfortunately I've http://jvdc.me/fix-502-bad-gateway-error-on-nginx-server-after-upgrading-php/ ran into quite an annoying issue which I had not encountered before, all pages https://www.scalescale.com/tips/nginx/502-bad-gateway-error-using-nginx/ returned "502 Bad Gateway" errors.I've done this a numerous time and the upgrade went very smoothly. I was even asked if I wanted to keep local configuration files or not. I choose yes and the installation proceeded. After installation was completed php got restarted and I received a notice that the upgrade was successful. Unfortunately error page when I went to check my website I got annoying 502 Bad Gateway" errors on every single page.What does this error message mean? A gateway, is like an access point, a bridge that communicate one service with another, in this case the gateway can be a service/application (WordPress, running on PHP) that is working and recieving requests from NGINX web server. So there is a communication issue between PHP and nginx custom error NGINX.Problem Solving 1: is PHP-FPM running?As you can see I am also running the latest version of NGINX (1.6.0 as of May 10th 2014) which was updated a few days earlier. It was clearly an issue with PHP so I started to think of what could've gone wrong. The first thing that you should always do is check if PHP is even running. Perhaps something went wrong while restarting PHP. Use the following command to check whether PHP-FPM is running.ps aux | grep phpps aux will output all processes that are running, so we add | grep php to only output processes with php in the name. If you see PHP processes, then this is not the the issue. Otherwise try to stop/start/restart PHP.sudo service php5-fpm stopsudo service php5-fpm startsudo service php5-fpm restartIf there are still no PHP-FPM processes running, you might try to remove PHP and reinstall it. If PHP-FPM is running correctly, skip this step and go to the following section.sudo apt-get remove php5 php5-cgi php5-fpmsudo apt-get install php5 php5-cgi php5-fpmProblem Solving 2a: is PHP-FPM listening correctly?A common issue is that the PHP-FPM service is not listening to the host/port which is configured in NGINX.
