Hello, we currently use a homegrown apache module, which maps urls to new domains and urls. For this we use a mysql-lookup. There are O (10000) entries in this table. Now we want to replace Apache with nginx (which is currently used as a load balancing proxy to a big zope cluster f?r 400+ Sites).
What would be the best way to achieve the same effect with nginx? We can live with a solution, where the mysql-table is exported once a night, a new nginx include is written and nginx is reloaded. I think it would be bad to port the apache module to nginx, as a mysql-lookup for each request reduces the benefits of nginx.
The lookup can be exact, so we do not need thousands of rewrites via regex.
Could you show example of mappings ? nginx can do lookups via "map" directive.
Yes I suspected already that "map" could be a solution, but I do not understand what the variables "0;" etc mean.
They are simple strings.
The mapping looks like this,
MAP: /0x0ac80f2b_0x008c8a6e -> http://medien-kunst- industrie.zzz.xxx.de/fachgruppen MAP: /0x0ac80f2b_0x015a8bd2 -> http://handel.yyy.xxx.de/ pressemitteilungen/presse_2004 MAP: /m -> http://mmm.xxx.de/ MAP: /berlin-brandenburg/lbz -> http://bb.xxx.de/
So it should be redirects returned to user ?
map $uri $new {
default http://some.default.de/;
/berlin-brandenburg/lbz http://bb.xxx.de/; /m http://mmm.xxx.de/;
... }
server { server_name www.xxx.de; rewrite ^ $new redirect; }
Currently they only arrive at one host "www.xxx.de" but it would be cool, if also different hosts could be covered, but that's not a stopper.
You may set up several maps or use
set $map $host$uri;
and define "map $map $new { ... }".
