Error creating data store, check the parameters. Error m

Answer 1

That error implies that you are attempting to add a PostgreSQL database rather than a PostGIS database. You need to add the PostGIS extension to the database with this command:

psql -d yourdatabase -c "CREATE EXTENSION postgis;"
psql -d yourdatabase -c "CREATE EXTENSION postgis_topology;"

This will then allow you to store geometries (and geographies) in your tables which GeoServer can then display as map layers.
