    387 !OpenStreetMap data can be stored in a PostGIS database & rendered using Mapnik.

    678 === Serve Tiles ===
    679 Tiles can simply be served by Apache:

    681 vim /etc/apache2/sites-available/mysite
    682 <VirtualHost *:80>

    689 </VirtualHost>
    690 apache2ctl restart
    691 }}}
    692 
    693 === WMS ===
    694 In order to serve the OSM data via WMS then can use mod_mapnik_wms:
    695  * http://wiki.openstreetmap.org/wiki/Mod_mapnik_wms
    696 {{{
    697 gpg --gen-key

    704 
    705 debuild
    706 }}}
    707 
    708 This data can then be converted by !GeoServer into a KML !SuperOverlay to display in Google Earth:

    711 
    712 === Rails Port ===
    713 This is needed to allow editing of the data using Potlatch, JOSM, etc
