Installation on Fedora

Note: Updated for F15 on June 26, 2011

• Install and run the database server if you haven't done this before (as root)

   yum install postgresql-server
   service postgresql initdb
   service postgresql start

Optionally set the service to start automatically

   chkconfig postgresql on

• Install the postgres postgis extension (as root)

   yum install postgis

• Setup the database

optionally, set password for the database user (as root)

   passwd postgres

otherwise run "su - postgres" as root

   su - postgres
   createdb -EUNICODE gis
   createuser -S -D -R apache
   echo "GRANT ALL ON SCHEMA PUBLIC TO apache;" | psql gis
   psql gis < /usr/share/pgsql/contrib/postgis-64.sql
   psql gis < /usr/share/pgsql/contrib/spatial_ref_sys.sql
   echo "grant all on geometry_columns to apache;" | psql gis
   echo "grant all on spatial_ref_sys to apache;" | psql gis

Note - on a 32 bit system change postgis-64.sql to postgis.sql on the 6th line above.

• Create your OSM working dir and checkout osm2pgsql project

   mkdir ~/osm
   cd ~/osm
   svn co http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/
   cd osm2pgsql

• To build osm2pgsql, follow Osm2pgsql#Fedora

• Download osm data - for example:

   wget http://planet.king-nerd.com/planet-090617.osm.bz2

• Import the map.osm into the gis database

   cp -r ~/osm/osm2pgsql /tmp
   cp ~/osm/map.osm /tmp

   ./osm2pgsql -S ./default.style ../map.osm

• Install mapnik

   yum install mapnik mapnik-devel mapnik-python proj-epsg

• Checkout mapnik data from svn

   cd ~/osm
   svn co http://svn.openstreetmap.org/applications/rendering/mapnik

• Download the Coastline data

   wget http://tile.openstreetmap.org/world_boundaries-spherical.tgz
   wget http://tile.openstreetmap.org/processed_p.tar.bz2
   wget http://tile.openstreetmap.org/shoreline_300.tar.bz2

• Files required since June 2010

   wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/10m-populated-places.zip 
   wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/110m-admin-0-boundary-lines.zip

• Unpack them up properly

   cd ~/osm/mapnik
   tar xvzf world_boundaries-spherical.tgz
   tar xvjf processed_p.tar.bz2 -C world_boundaries
   tar xvjf shoreline_300.tar.bz2 -C world_boundaries
   unzip 10m-populated-places.zip -d world_boundaries
   unzip 110m-admin-0-boundary-lines.zip -d world_boundaries

• Setup the mapnik environment

   cd ~/osm/mapnik
   cp archive/set-mapnik-env .
   vim set-mapnik-env
   change "export MAPNIK_DBNAME='osm'" to 'gis'
   change "export MAPNIK_DBUSER=`whoami`" to 'apache'

• Test mapnik

   cp ~/osm/mapnik/generate_tiles.py ~/osm/mapnik/z0_generate_tiles.py

   vim ~/osm/mapnik/z0_generate_tiles.py
   #-------------------------------------------------------------------------
   #
   # Change the following for different bounding boxes and zoom levels
   #
   # Start with an overview
   # World
   bbox = (-180.0,-90.0, 180.0,90.0)
   
   render_tiles(bbox, mapfile, tile_dir, 0, 5, "World")
   Change the 5 to 0, then
   Comment out all of the render_tiles line that follows with a '#'

• Copy/run mapnik

   cp -r ~/osm/mapnik ~
   cd ~/mapnik/
   source set-mapnik-env
   ./z0_generate_tiles.py 

• Check file tiles/0/0/0.png is a world map image
