I learned how to get NGINX to return 503 customer error pages,
but I cannot find out how to do the following:
Sample config file:
location / {
root www;
index index.php;
try_files /503.html =503;
}
error_page 503 /503.html;
location = /503.html {
root www;
}
As you can see, according to the code above, if a page called 503.html is found in my root direct开发者_如何学运维ory, the site will return this page to the user.
But it seems that although the code above works when someone simply visits my site typing
- http://www.example.com
it does not trap requests like:
- http://www.example.com/profile.php
With my code, the user can still see the profile page or any other pages besides index.php.
The question:
How do I trap requests to all pages in my site and forward them to 503.html whenever 503.html is present in my root folder?
The below configuration works for close to the latest stable nginx 1.2.4.
I could not find a way to enable a maintenance page with out using an if but apparently according to IfIsEvil it is an ok if.
- To enable maintenance
touch /srv/sites/blah/public/maintenance.enable. You canrmthe file to disable. - Error
502will be mapped to503which is what most people want. You don't want to give Google a502. - Custom
502and503pages. Your app will generate the other error pages.
There are other configurations on the web but they didn't seem to work on the latest nginx.
server {
listen 80;
server_name blah.com;
access_log /srv/sites/blah/logs/access.log;
error_log /srv/sites/blah/logs/error.log;
root /srv/sites/blah/public/;
index index.html;
location / {
if (-f $document_root/maintenance.enable) {
return 503;
}
try_files /override.html @tomcat;
}
location = /502.html {
}
location @maintenance {
rewrite ^(.*)$ /maintenance.html break;
}
error_page 503 @maintenance;
error_page 502 =503 /502.html;
location @tomcat {
client_max_body_size 50M;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header Referer $http_referer;
proxy_set_header X-Forwarded-Proto http;
proxy_pass http://tomcat;
proxy_redirect off;
}
}
Updated: changed "if -f" to "try_files".
Try this:
server {
listen 80;
server_name mysite.com;
root /var/www/mysite.com/;
location / {
try_files /maintenance.html $uri $uri/ @maintenance;
# When maintenance ends, just mv maintenance.html from $root
... # the rest of your config goes here
}
location @maintenance {
return 503;
}
}

The other answers are both correct, but just to add, that if you use internal proxies you also need to add proxy_intercept_errors on; on one of your proxy servers.
So for example...
proxy_intercept_errors on;
root /var/www/site.com/public;
error_page 503 @503;
location @503 {
rewrite ^(.*)$ /scripts/503.html break;
}
Years later, here is what I currently use for completely custom error messages.
HTML Error pages are stored in /http-error directory located in your site root directory.
