Notes on installing Virtuoso-Opensource7 on Ubuntu

git clone https://github.com/openlink/virtuoso-opensource.git Virtuoso-Opensource
cd Virtuoso-Opensource
git checkout stable/7
sudo apt-get install libtool gawk gperf autoconf automake libtool flex bison m4 make openssl libssl-dev
./autogen.sh
./configure
make
sudo make install

Checkinstall will make a debian package from the changes made by the command make install. If you prefer you can also just use sudo make install instead. Now virtuoso is installed. Next is setting up a user and starting virtuoso:

sudo useradd virtuoso --home /usr/local/virtuoso-opensource
sudo chown -R virtuoso /usr/local/virtuoso-opensource
cd /usr/local/virtuoso-opensource/var/lib/virtuoso/db
sudo -H -u virtuoso ../../../../bin/virtuoso-t -f &

Now Virtuoso should be running. Time to change some user rights:

  • Go to http://localhost:8890/conductor/
  • Log in using dba / dba
  • Go to System Admin -> User Accounts and edit user dba
  • Change the password (2x) and click Save
  • edit user SPARQL
  • Add the role SPARQL_UPDATE and click Save

Next is setting up virtuoso for use by LSM. Go to Linked Data and execute the query:

CREATE GRAPH <http://lsm.deri.ie/OpenIoT/sensormeta#>
CREATE GRAPH <http://lsm.deri.ie/OpenIoT/sensordata#>
CREATE GRAPH <http://lsm.deri.ie/OpenIoT/functionaldata#>

If you want to use different graph names, make sure to also change those in the configuration file jboss/standalone/configuration/openiot.properties

Virtuoso should now be ready for use by LSM.

An example init script for virtuoso on Debian/Ubuntu is below.

#!/bin/sh
#
# Example init.d script with LSB support.
#
# Please read this init.d carefully and modify the sections to
# adjust it to the program you want to run.
