A short note on installing the neo4j graph database on a Ubuntu 14.04 virtual private server (VPS).

Things you need:

• add-apt-repository (you may have this already)

  sudo apt-get install python-software-properties
  

  and / or (not sure)

  sudo apt-get install software-properties-common
  

• openjdk-8-jre-headless
  Version 8 is not officially available for 14.04, but there are PPAs.

  sudo add-apt-repository ppa:openjdk-r/ppa
  sudo apt-get update
  sudo apt-get install openjdk-8-jre-headless
  

• neo4j

  wget -O - https://debian.neo4j.org/neotechnology.gpg.key | sudo apt-
  echo 'deb https://debian.neo4j.org/repo stable/' | sudo tee /etc/apt/sources.list.d/neo4j.list
  sudo apt-get update
  sudo apt-get install neo4j
  

• Check the status of neo4j

  service neo4j status
  

Installation done!

You can access the web interface via http://localhost:7474. To grant access from outside, you need to modify the neo4j config

/etc/neo4j/neo4j.conf

Under ‘Network connector configuration’, uncomment the line

dbms.connectors.default_listen_address=0.0.0.0

Finally, restart neo4j:

service neo4j restart

Now, the neo4j web interface should be available here:

http://YOUR_SERVER_IP:7474

Done.
