Hi OSMers.


I installed Mapnik and  I can render my own tiles.
I now want to go the next step which is to use mod_tile but I can't get it
to work.
I'm using Ubuntu 11.10 64 bits and followed this how to :
http://wiki.openstreetmap.org/wiki/HowTo_mod_tile.

Browsing the map page : http://localhost/map.html does not display anything
and does not generate the tiles.
Trying this URL does not  http://localhost/osm-tiles2/0/0/0.png generate
the tiles as well.

Below is the output of ./renderd.py
Layer name: default
    URI(/osm_tiles2/) = XML(/home/psi/bin/mapnik/osm.xml)
Started render thread Thread-1
Started render thread Thread-2
Started render thread Thread-3
Started render thread Thread-4

There is no renderd error in the syslog

And http://localhost/osm-tiles2/0/0/0.png generates the following apache
error log.
[Fri Dec 02 15:09:25 2011] [error] [client 127.0.0.1] File does not exist:
/var/www/osm-tiles2


In the map.html code I can see that the URI of the rendered tiles are in
the folder /osm_tiles2/ but I do not see how the redirection is done
at the apache level to locate /osm_tiles2).
var newL = new OpenLayers.Layer.OSM("Default",
"/osm_tiles2/${z}/${x}/${y}.png", {numZoomLevels: 19});

Runing the ./render_list -m default -a -z 0 -Z 10 will just display the
following information.

./render_list -m default -a -z 0 -Z 10

Requesting xml(default) x(0) y(0) z(0)
Rendering all tiles for zoom 6 from (0, 0) to (63, 63)




I will greatly appreciate the list help to solve this.

Thank you.

Sewa
