Fuseki File System Layout

There are two areas: the fixed files provided by the distribution and the changing files for the local deployment,including the default location for TDB databases.

Two environment variables control the file system usage. Symbolic links can be used to create variations on the standard layout.

FUSEKI_HOME - this contains the fixed files from the distribution and is used for Unix service deployments. When deployment as a WAR file, everything is in the WAR file itself.

FUSEKI_BASE - this contains the deployment files.

Mode Environment Variable Default Setting
Service FUSEKI_HOME /usr/share/fuseki
FUSEKI_BASE /etc/fuseki
Webapp FUSEKI_HOME N/A (Files in the Fuseki .war file)
FUSEKI_BASE /etc/fuseki
Standalone FUSEKI_HOME Current directory
FUSEKI_BASE ${FUSEKI_HOME}/run/

When run in a web application container (e.g. Tomcat, Jetty or other webapp compliant server), FUSEKI_BASE will be /etc/fuseki.

If FUSEKI_BASE is the same as FUSEKI_HOME, be careful when upgrading not to delete server deployment files and directories.

The system_files/ keeps a copy of any assemblers uploaded to configure the server. The master copy is kept in the system database.

Resetting

To reset the server, stop the server, and delete the system database in system/, the system_files/ and any other unwanted deployment files, then restart the server.
