can t make nginx try files to work with default index html

Question

I want to redirect users based on their IP with %geoip_country_code module of nginx.

Configuration:

server {
      listen 80;
      gzip on;
      server_name example.com;
      root html/example;
      location / {
        index index.html;
        try_files /$geoip_country_code/index.html /index.html;
      }
      location ~* \.(gif|jpg|jpeg|png|js|css)$ { }
  }

I just want to redirect the users based on their country and it is working perfectly fine for my own country but if I try and open from a different country it shows internal server error. It's not going to the default index page. Am I doing soemthing wrong here?

Answer 1

You can set a default action in try_files statement. It's the lst element in the try_files which could be either set to a response code or a URI. Here the /index.html starts looking for a new location to process the request and returns to the start, creating a redirection loop.

You can try making /index.html a file term:

try_files /$geoip_country_code/index.html /index.html =404;

Here the =404 is never tried because /index.html is always there.

Or you can try the generic sol.

try_files /$geoip_country_code$uri $uri /index.html;

try_files tries the literal path you specify in relation to the defined root directive and sets the internal file pointer. If you use for instance try_files /app/cache/ $uri @fallback; with index index.php index.html; then it will test the paths in this order:

1. $document_root/app/cache/index.php
2. $document_root/app/cache/index.html
3. $document_root$uri

Here's another convenient use of try_files, as unconditional redirects to named locations. The named locations are effectively acting as subroutines, saving duplication of code. When the first argument to try_files is "_" the fallback redirect is always taken.

    location =/wp-login.php { try_files _ @adminlock; }
    location ^~ /wp-admin/  { try_files _ @adminlock; }
    location @adminlock  {
            allow 544.23.310.198;
            deny all;
            try_files _ @backend;
            # wp-admin traffic is tiny so ok to send all reqs to backend 
    }
    location ~ \.php {  try_files _ @backend; }
    location / { try_files $uri $uri/ =403; }
    location @backend {
            fastcgi_pass 127.0.0.1:9000;
            include snippets/fastcgi-php.conf;
    }
