This document provides instructions for setting up PostGIS by installing PostgreSQL and PostGIS, creating a database cluster and database, configuring the database to listen on a specific IP and port, importing OSM data using osm2pgsql, and trusting connections from the local computer.

1. Setting up PostGIS
• Here is what I do on PostGIS 8.4 (granted, an older vsion)
!
• Install Postgresql and PostGIS
!
• Create cluster (just DB)
!
!
!
initdb -D /var/lib/postgresql/data
• Start postgres
postgres -D /var/lib/postgresql/data

2. Setting up PostGIS
• Create database
• As “postgres" user, create postgresql tables using Imposm’s
create-db.sh script (and modified for the right db name)
• (I was using Imposm 2.0)
create-db.sh

3. Setting up PostGIS
• Set it so I bind to the IP and port and expose it
!
!
!
!
!
In /var/lib/postgresql/data/postgresql.conf
• Trust the connection to the database to my computer
In /var/lib/postgresql/data/pg_hba.conf

4. Importing into PostGIS
• Finally, import the data
osm2pgsql -c -G -U postgres -d osm -S /usr/share/
osm2pgsql/default.style your_file.osm.pbf
(or .osm)
