Running Fuseki

Fuseki can be run in a number of ways:

See "Fuseki Configuration" for information on how to provide datasets and configure services.

Fuseki as a Standalone Server

This is running Fuseki from the command line.

fuseki-server [--mem | --loc=DIR] [[--update] /NAME]

# Fuseki v1 style compatibility
fuseki-server --config=CONFIG

where /NAME is the dataset publishing name at this server in URI space.

See fuseki-server --help for details of more arguments.

FUSEKI_BASE, the runtime area for the server instance, defaults to the run/ directory of the current directory.

Fuseki v2 supports the same style of configuration file as Fuseki v1 but it is better to separate the data service definitions from the server configuration with one definition per file in FUSEKI_BASE/configuration; see "Fuseki Configuration".

If you get the error message Can't find jarfile to run then you either need to put a copy of fuseki-server.jar in the current directory or set the environment variable FUSEKI_HOME to point to an unpacked Fuseki distribution.

Unlike Fuseki v1, starting with no dataset and no configuration is possible. Datasets can be added from the admin UI to a running server.

Fuseki as a Service

Fuseki can run as an operating system service, started when the server machine boots. The script fuseki is a Linux init.d with the common secondary arguments of start and stop.

Process arguments are read from /etc/default/fuseki including FUSEKI_HOME and FUSEKI_BASE. FUSEKI_HOME should be the directory where the distribution was unpacked.

Fuseki as a Web Application

Fuseki can run from a WAR file. Fuseki requires at least support for the Servlet 3.0 API (e.g. Apache Tomcat 7 or Jetty 8) as well as Java8.

FUSEKI_HOME is not applicable.

FUSEKI_BASE defaults to /etc/fuseki which must be a writeable directory. It is initialised the first time Fuseki runs, including a Apache Shiro security file but this is only intended as a starting point. It restricts use of the admin UI to the local machine.

Fuseki as an Embedded SPARQL Server

Fuseki can be run from inside an Java application to provide SPARQL services to application data. The application can continue to access and update the datasets served by the server.

Basic example:

Dataset ds = ...
FusekiServer server = FusekiServer.create()
  .add("/dataset", ds)
  .build() ;
server.start() ;

See the full documentation for details of configuration and working with data shared with the embedded Fuseki instance.

Simple Development Standalone Server

The artifact org.apache.jena:jena-fuseki-basic is a packaging of the embedded server that runs from the command line. Unlike the full Fuseki server, it is only configured from the command line and has no persistent work area on-disk.
