Tile-Server problems


I hope you can help me with setting up / troubleshooting a tile-server. I´ve installed Ubuntu 16.0.4 and followed the instructions on https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04

I´ve importet germany-latest and renderd is running and reporting no error. If i try to load /osm_tiles/16/33899/22005.png i´ll get a 404 after a minute.

I´ve also tried render_list:

time render_list -a -z 16 -Z 16 -x 33899 -X 33900 -y 22004 -Y 22005 -n 2 -s /var/run/renderd/renderd.sock
debug: init_storage_backend: initialising file storage backend at: /var/lib/mod_tile
Rendering client
Starting 2 rendering threads
Rendering all tiles from zoom 16 to zoom 16
Rendering all tiles for zoom 16 from (33899, 22004) to (33900, 22005)
Waiting for rendering threads to finish

But nothings seems to happen. In htop i see no activity at all (one task running, which is htop :wink: ) However, the render_list process gets listed twice with 161M virtual memory consumption but no used processor time.

/var/lib/mod_tiles is empty (except for planet-import-complete).

Can you give me some advice on finding out why the rendering is not working?


Typically I’d run renderd in the foreground first to try and spot any errors - see “Running renderd for the first time” in https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/ . I’d expect some errors to pop up there suggesting what the problem is.
