mod_tile/renderer/apache configuration issue

Hi,
     I have built my own openstreetmap server (Ubuntu 10.04) using the guidelines from http://weait.com/content/build-your-own … map-server
  I was able to generate tiles using mapnik successfully.
then I installed mod_tile using the following instructions :
******************************************************************************
svn co http://svn.openstreetmap.org/applicatio … s/mod_tile
cd mod_tile

Edit render_config.h so that all references to lib64 are lib if on a 32bit OS.
Open renderd.conf change the path to WWW_ROOT to the correct path and the XML
file should point to the one generated in the previous step by mapnik.
Once everything is changed:
sudo make
sudo install
sudo mkdir /var/www/osm_tiles2
sudo mkdir /var/www/direct
sudo mkdir /var/run/renderd

Edit /etc/apache2/conf.d/mod_tile.conf to match your settings
and change the socket for renderd to /tmp/osm-renderd
Make an empty file planet-import-complete in /var/lib/mod_tile/
Restart apache

Run renderd via
sudo ./mod_tile/renderd
******************************************************************************
when I run renderer -f It runs without any errors and when I request for a tile http://LAN_server_IP/osm_tiles2/0/0/0.png it gives me 404 error.And when I open  http://LAN_server_IP/mod_tile  all values are 0

when I do apache2ctl -M  it displays  --> tile_module (shared)

I have also disabled SElinux using -->   sudo echo 0 > /selinux/enforce

Re: mod_tile/renderer/apache configuration issue

I was able to generate tiles using mapnik successfully.

Where did mapnik store the produced tiles?

What does mapnik have to to with the renderer? Does the renderer generate tiles or does it use mapnik to generate them? Did mapnik generate the ...//0/0/0.png tile already? Then where does it reside?

Please explain a bit how the rendere uses mapnik, if it does.

For me it is strange that "osm_tiles2/0" is called a file.

Now did you check if file "/var/www/osm_tiles2/0/0/0.png" is in the mentioned directory?

Or is /var/www/osm_tiles2/0/0 not a physical directory?

Re: mod_tile/renderer/apache configuration issue

thankyou so much for replying...I got a solution using the mailing list...The solution was I was giving the wrong path in renderd.conf i first set the path to
URI=/var/www
but it should be /osm_tiles2/
Then I changed the ownership of /var/www  to www-data
and also changed the write permissions of  /var/lib/mod_tile/ to 777
restarted apache and executed the renderd..it started working.

FOR TILE GENERATION USING MAPNIK
it has a script generate_image.py  and generate_tiles.py  which generates image or set of tiles using the bounding box and the number of zoom levels for which you want to generate ...and it starts generating tiles on the path that you set to write on
