Ubu: 2. Install Neo4j

Graphlytic uses Neo4j database as base data storage. You can use existing Neo4j database or install a new one. If you use exiting database be careful that Graphlytic stores some custom data into Neo4j database. Existing data stays unchanged because Graphlytic don't execute any change to existing data if it is not required by user. For better safety and data separation we recommend to use separate Neo4j database to work with Graphlytic. For information about required version see Requirements.

1. Install Neo4j

How to install Neo4j see Neo4j installation manual. It is strictly recommended to follow instructions at Neo4j manual. Here is short description how to install Neo4j but use this description with care.

1.1. Install Neo4j as a console application

If you don't have license for Neo4j Enterprise you can use Neo4j Community edition. Download correct version for your operating system. Download "tar" file for Linux.
