I want to cache a layer from Geoserver. I use Geoserver 2.5.1 on Ubuntu 13.10.

  • In the web.xml file under tomcat7/webapps/geoserver/WEB-INF I added the following part: <context-param> <param-name>GEOWEBCACHE_CACHE_DIR</param-name> <param-value>/opt/gwc</param-value> </context-param>
  • I enabled Enable direct integration with GeoServer WMS under Caching defaults.
  • I use the sample data tiger:giant_polygon where Create a cached layer for this layer is enabled

After opening the tile preview with EPSG:4326 /jpeg for the layer, the folder where my tiles are supposed to be saved is still empty. Also the DISK USED colum shows N/A. enter image description here

What is missing?

    Have you given ownership of /home/uli/Downloads/tiles to Tomcat7? – Mark Cupitt Jun 23 '14 at 11:22

    also, check you Tomcat7 Logs as per here – Mark Cupitt Jun 23 '14 at 11:24

    Ok, you changed the directory, have you given tomcat7 ownership of /opt/gwc – Mark Cupitt Jun 23 '14 at 11:28

    If I try to change the ownership to Tomcat7 I get: chown: invalid user: ‘Tomcat7’ – ustroetz Jun 23 '14 at 11:29

    Also in the Geoserver Beginner's Guide book the owner of the folder is root. Are you sure the ownership needs to change? – ustroetz Jun 23 '14 at 11:34

Tomcat and Geoserver need write permissions. You need to give tomcat7 ownership of /opt/gwc

  • The tiles are now saved inside /opt/gwc. Though the column Disk Used still shows N/A. What is the reason for that? – ustroetz Jun 23 '14 at 12:07
  • You need to ask a new question on that issue .. but possible you do not have enough tiles in there yet .. I have never paid much attention to that, I look at the directories to see how the caching is populating .. – Mark Cupitt Jun 23 '14 at 12:26

    you have to turn quota on for the disk used to update – Ian Turton Jun 23 '14 at 12:31
