问题 I am using nginx as a frontend to an apache server. The config file looks like: upstream apache { server localhost:8000; } server { listen 80; error_page 503 /www/static/503.html; # need some magic here # location /static/ { root /www/static/; } location / { proxy_path http://apache/; } } For now, when apache is down, I receive a plain 502 page generated by nginx. How to make it serve my custom error page and return status code 503 which is more relevant in this situation? 回答1: Something like

问题 We use Apigee proxy to invoke our API. All works well when we test it out within Apigee trace. Also works fine with curl. But on a browser, it gives a 503. This is not consistent though, sometimes it gives a 200 on the browser too. Tried Chrome and Firefox, same behavior. Our API still executes well though. We do not return any response, merely set the status. Any ideas on what we could try out to get a 200 on the browser? 回答1: Couple of things to check: Check if your Browser has a DNS entry

问题 It was pointed out to me that my server is insecure, because anyone could read any file through PHP, even if it was out of his DocumentRoot. I decided to reconfigure whole apache and all configuration files for virtual hosts and installed Mod FastCGI and I managed to get it running quite nicely, I don't have problems with rights anymore. But there seems to be another problem. When I try to load more than 3 sites (on different VirtualHosts => different users on different threads) page loads

问题 I am encountering a 503 - Service Unavailable error. I checked the event log and found this: The Module name FastCgiModule path C:\WINDOWS\System32\inetsrv\iisfcgi.dll returned an error from registration. The data is the error. Note: Every time I try to visit my website, I found that the DefaultAppPool will auto-stop. And also found this in event log: Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

问题 I have installed wamp on a virtual server, and everything seems fine (i.e. the server is running and I'm seeing the color green). What seems to be going on is that when I try to run a web site (for example /localhost/sitename), I'm getting a 503 Service Unavailable, Service temporarily unavailable. Please try again soon. Despite that everything is running, no apache errors and so on. What would cause the 503 error to show? 来源： https://stackoverflow.com/questions/21125047/im-getting-a-service

问题 any ideas how to replace Apache HTTP 500 (Internal Server Error) error by HTTP 503 (Service Unavailable) on PHP error once PHP error displaying is off? This is much better option to inform spiders to back to the site soon... P.S. would be great to be able to append Retry-After to the 50x error codes if possible... cheers, /Marcin 回答1: I assume you are referring to PHP's new (since 5.2.4) default behaviour of throwing a 500 if an error occurs, and no other output is being made. AFAIK, that

问题 I have an Azure service that has been running for a long period of time. It builds a word or powerpoint document based on arguments in the request and returns a uri to the build document. This is access via a visualforce page, when you click a button, it calls the service and displays a link to the document that has just been built. Simple. All of a sudden, I get an apparently random 503 Service Unavailable error. Sometimes I click the button, no problem. Other times a 503 error. Each time
