GraphDB is normally built against the latest version of the [Aduna OpenRDF Sesame framework|http://www.openrdf.org/]. If using GraphDB with this version then the easiest way to deploy an a GraphDB server instance is to copy the re-packaged Sesame Web applications (.war files) in to the Tomcat {{webapps}} directory. They can be found in the {{sesame_owlim}} directory in the GraphDB distribution ZIP file. These Web applications have been modified as follows:

* *openrdf-sesame.war:* The Sesame server application. All GraphDB-Enterprise and 3{^}rd^ party jar files have been added to this package, so that it can be used immediately after deployment.
After deployment, GraphDB-Enterprise master and worker nodes can be created using the workbench application as follows:
* Start a browser and go to the Workbench Web application using a URL of this form: [http://localhost:8080/openrdf-workbench/] \- substituting {{localhost}} and the {{8080}} port number as appropriate.
* Click 'change server', if necessary, to select a Sesame server instance, if it is running on a different machine. The server URL will be of this form: [http://localhost:8080/openrdf-sesame].
* After selecting a server, click 'New repository'.
* Select 'GraphDB-Enterprise worker node' or 'GraphDB-Enterprise master node' from the drop-down list and enter the repository ID and description. Then click 'next'.
* For master nodes, there is nothing more to be specified, so just click 'create'. For worker nodes, fill in the fields as required (referring to the owlim-configurator spreadsheet as necessary) and click 'create'. You can specify a worker node license file at this step, if you have one, but note that you must use forward slashes ('/') as file separators (even on Windows).
* A message is displayed, which gives details on the new repository and this should also appear in the repository list (click 'repositories' to see this).


{note}
All worker nodes that take part in the same cluster (connect to the same master), must be configured identically (apart from the repository name and label).
{note}


A suitable application server must be installed. The examples in this guide assume [Apache Tomcat|http://tomcat.apache.org/] version 6.x is used. Importantly, the user must have sufficient privileges to write to the Tomcat {{webapps}} directory and to stop and start the Tomcat daemon.

A [GraphDB-Enterprise|http://www.ontotext.com/products/ontotext-graphdb/graphdb-enterprise/] distribution is required. This is published as a zip file. The examples in this guide use version 5.6.
The [Aduna OpenRDF Sesame framework version 2.7|http://www.openrdf.org/] or higher is required for the longer installation. The examples in this guide use version 2.7.8.
