What you are talking about is vector based data which can be put into a
project as either raster tiles generated statically, or vector tiles
generated on the fly, and what you can actually get in practice will
depend on what you have the skill or ability to implement. Implementing
a tileserver of any kind requires quite a skillset.
I would go back to the shapefiles and look at the amount of detail that
is needed at each zoom level. You can implement style rules that work at
different scale levels, meaning the level of detail that is displayed at
a small scale can be simplified quite a lot. I use this for generating
XYZ tiles for a web site I maintain, because zoomed right out at zoom
level 1 (something like a scale of 1:500 000) it is much easier to find
the general area of the map without a lot of unnecessary clutter and has
the bonus of taking less time to render.

Hi Paul,
thank you for the links!
Despite this is for Windows (I use Linux), it is for a XYZ tileserver
but I need vector tiles. Raster tiles may be too many for whole Europe
in plenty zoom levels. And I don't know where to get them, as everywhere
I know you can only download small regions; the mentioned link in the
video opentiles.com does not exist any more.
Postgres may not work for me, as I read it needs at least as much RAM as
the file size to import the map into the database. My vector tiles have
20 GB while my PC only 8 GB. It may run out of memory.
But probably this points me to the right direction. I just discovered
there is tileserver-GL https://tileserver.org/ and tileserver-PHP
available and I gave them a try.
Don't know why, but tileserver-gl can not be installed on Linux with nmp
(compile error due to unexpected OS), and there are only the options npm
or Docker. Docker is not in the standard repositories so foreign package
sources shall be added, what I really want to avoid because of the high
security risk. I tried also tileserver-PHP, but strangely as it is
intended as a local installation, it shows not even a configuration
interface without internet access. It pulls its css and some javascript
from an external server :-/ Also, I can not get it running with the
maptiler .mbtiles because the WMTS capabilities (.mbtiles is read!)
seems to be provided in a wrong syntax.
So, still stuck...
Regards,
Andreas
