Hi, I struggle to set up two different map styles for the mapnik-osm rendering tool chain. According to some help I already found here and on gis.stackexchange, I have set up the renderd.conf for two map styles. But I can't get it to work. When I enter the URL for the second map style ("http://myserverurl/print/0/0/0.png") the browser says "The requested URL was not found on this server." With the default map style it is no problem ("http://myserverurl/osm/0/0/0.png").

I coulnd't find any other setting in the mod_tile or renderd config files to enable the "print" map style to work. What did I oversee or is there anything else I need to do? The renderd.conf looks like this:


[renderd]
stats_file=/var/run/renderd/renderd.stats
socketname=/var/run/renderd/renderd.sock
num_threads=10
tile_dir=/var/lib/mod_tile

[mapnik]
plugins_dir=/usr/lib/mapnik/3.0/input
font_dir=/usr/share/fonts/truetype/ttf-dejavu
font_dir_recurse=false

[default]
URI=/osm/
TILEDIR=/var/lib/mod_tile
TILESIZE=256
XML=/home/osm/openstreetmap-carto-4.24.1/style.xml
DESCRIPTION=Default map style

Firstly, make sure to use a different TILEDIR for each style, or else the tiles will overwrite each other. (Typically you would use something like /var/lib/mod_tile/osm and /var/lib/mod_tile/print in your case.) Secondly, assuming you are using the LoadTileConfig directive in your Apache configuration: Have you done a systemctl reload apache2 (or apache2ctl restart) after adding your new style?

Hi, thanks for the quick reply. Yes I restarted both renderd and apache2. I read that depending on the name ("default" and "print") a seperate directory is created automatically. So far I only see the default directory in /var/lib/mod_tile/ I tried it with two different directories now as you recommended, but nothing changed.

Do a

sudo -u {yourUserAccountforRenderd} mkdir /var/lib/mod_tile/print

and restart renderd and apache2 again.

If that does not help, check the error/info output at /var/log/syslog while restarting renderd.

It smells like a problem with permissions or missing shapefiles (did you load the shapefiles for the print style as well or referenced the osm-carto ones in the project.mml for the print.xml?)

Thanks, that didn't work, but brought me to the solution!

So the solution was: In the /var/www/ directory was only an "osm" folder (http://myserverurl/osm/0/0/0.png worked). I created another directory named like the additional mapstyle ("print"). And gave the permission chmod -R 755 /var/www.

After a restart of Apache it now serves the other map style through http://myserverurl/print/0/0/0.png.
