tile.libre.is

Tile server for https://maps.libre.is/.

Not running at the moment, until more disk space is available.

switch2osm.org

Self-hosting tiles for maps.

Debian

Install deps.

sudo apt install sudo screen locate libapache2-mod-tile renderd git tar \
  unzip wget bzip2 apache2 lua5.1 mapnik-utils python3-mapnik \
  python3-psycopg2 python3-yaml gdal-bin node-carto postgresql \
  postgresql-contrib postgis postgresql-15-postgis-3 \
  postgresql-15-postgis-3-scripts osm2pgsql net-tools curl

PostGIS

Thusly.

Tune Postgres, ala:

shared_buffers = 1GB
work_mem = 50MB
maintenance_work_mem = 10GB
autovacuum_work_mem = 2GB
wal_level = minimal
checkpoint_timeout = 60min
max_wal_size = 10GB
checkpoint_completion_target = 0.9
max_wal_senders = 0
random_page_cost = 1.0

sudo -u postgres -i
createuser _renderd
createdb -E UTF8 -O _renderd gis
psql

At the Postgres prompt:

\c gis
CREATE EXTENSION postgis;
CREATE EXTENSION hstore;
ALTER TABLE geometry_columns OWNER TO _renderd;
ALTER TABLE spatial_ref_sys OWNER TO _renderd;
\q

Carto

Set up Openstreet map Carto:

mkdir ~/src
cd ~/src
git clone https://github.com/gravitystorm/openstreetmap-carto
cd openstreetmap-carto
carto project.mml > mapnik.xml

Map Data

Just using Azerbaijan for example, until more disk is available…

mkdir ~/data
cd ~/data
wget https://download.geofabrik.de/asia/azerbaijan-latest.osm.pbf
# meh, should have separate user...
chmod o+rx ~
sudo -u _renderd osm2pgsql -d gis --create --slim  -G --hstore \
  --tag-transform-script ~/src/openstreetmap-carto/openstreetmap-carto.lua \
  -C 2500 --number-processes 1 \
  -S ~/src/openstreetmap-carto/openstreetmap-carto.style \
  ~/data/azerbaijan-latest.osm.pbf

Or do the whole planet. If created above, maybe faster to drop the old database first than do an update. XXX

mkdir ~/data
cd ~/data
# Find a mirror here:
# https://wiki.openstreetmap.org/wiki/Planet.osm
# planet-latest.osm.pbf is 77G
wget https://ftp.osuosl.org/pub/openstreetmap/pbf/planet-latest.osm.pbf
chmod o+rx ~
sudo -u _renderd osm2pgsql -d gis --create --slim  -G --hstore \
  --tag-transform-script ~/src/openstreetmap-carto/openstreetmap-carto.lua \
  -C 98304 --number-processes 8 \
  -S ~/src/openstreetmap-carto/openstreetmap-carto.style \
  ~/data/planet-latest.osm.pbf

Indexes

Thusly.

cd ~/src/openstreetmap-carto/
sudo -u _renderd psql -d gis -f indexes.sql

Shapefiles

Thusly.

cd ~/src/openstreetmap-carto/
mkdir data
sudo chown _renderd data
sudo -u _renderd scripts/get-external-data.py

Fonts

Thusly.

cd ~/src/openstreetmap-carto/
scripts/get-fonts.sh

renderd

Edit /etc/renderd.conf thusly, add to bottom, changing “accountname” to the user used above:

[s2o]
URI=/hot/
XML=/home/accountname/src/openstreetmap-carto/mapnik.xml
HOST=localhost
TILESIZE=256
MAXZOOM=20

Edit /usr/lib/systemd/system/renderd.service and add to [Service] section:

Environment=G_MESSAGES_DEBUG=all

Apache

Thusly…

cd /etc/apache2/conf-available/
sudo wget https://raw.githubusercontent.com/openstreetmap/mod_tile/python-implementation/etc/apache2/renderd.conf
sudo a2enconf renderd
sudo systemctl reload apache2
sudo systemctl daemon-reload
sudo systemctl restart renderd
sudo systemctl restart apache2
sudo mkdir /var/lib/mod_tile
sudo chown _renderd /var/lib/mod_tile
sudo /etc/init.d/renderd restart
sudo /etc/init.d/apache2 restart

Then go check it here:

View Tiles

Thus.

cd /var/www/html
sudo wget https://raw.githubusercontent.com/SomeoneElseOSM/mod_tile/switch2osm/extra/sample_leaflet.html
sudo mv sample_leaflet.html index.html
sudo sed -i -e 's/127.0.0.1/tile.libre.is/g' index.html

Using Tiles

See:

Certbot

Add certs.

sudo apt install python3-certbot-apache
sudo certbot -d tile.libre.is
sudo systemctl restart apache2

TODO

  • Get more space.

  • Add more tiles…
