postgres comes by default with Ubuntu. pg_routing needs postgis:
sudo apt install postgis postgresql-14-postgis-3
sudo apt install postgresql-14-pgrouting
To use postgres we login as user postgres
sudo -i -u postgres
We now can use commands to create databases, users ..etc:
createuser routingTest
createdb routing_db -O routingTest
To run sql commands with postgres we must start the psql app.
example workflow, we connect to postgress and drop an existing DB:
sudo -i -u postgres
psql
\l
DROP DATABASE postgis_db;
\l
createuser geocoder
createdb routing_db -O geocoder
after creating a db we connect to it /connect db_name and install the extensions needed:
CREATE EXTENSION postgis;
CREATE EXTENSION pgRouting;
we copy the data to the db using
osm2pgrouting -d routing_db -U postgres -h localhost -p <postgress port number> -W your_password -f map1.osm -c “.\mapconfig.xml” — clean
to get the port number of postgres we use pg_lsclusters
osm2pgrouting -d routing_db -U postgres -h localhost -p 5433 -W postgres -f "/mnt/92804264-c37f-48cb-8ec5-49bc5be832fa/hasan/playground/bunyan/personal_projects/geocoder/assets/map.osm" -c "/mnt/92804264-c37f-48cb-8ec5-49bc5be832fa/hasan/playground/bunyan/personal_projects/geocoder/mapconfig.xml" — clean
docker run --rm -d --network host --name geocoderr -e PORT=3000
-e PGUSER=postgres
-e PGHOST=127.0.0.1
-e PGPASSWORD=postgres
-e PGDATABASE=osm_ele
-e PGPORT=5433 hasanaga/geocoder
