Serve multiple map styles with mapnik and mod_tile from one server & database

Question

I struggle to set up two different map styles for the mapnik-osm rendering tool chain. According to some help I already found on gis.stackexchange, I 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 couldn't find any other setting in the mod_tile or renderd config files to enable the "print" map style to work. 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

Answer 1

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.
