Installation

01: Open a terminal window

$ sudo apt update

03: Install Java. We will be using OpenJDK 8. Other possible candidates are Oracle Java 8 or IBM Java 8. Enter with y, when asked to confirm installation.

$ sudo apt install openjdk-8-jdk

04: Verify that Java has been installed.

$ sudo apt-get update

Accept database connection from anywhere

01: Edit the neo4j configuration

$ sudo nano /etc/neo4j/neo4j.conf

02: Un-comment the following config to make the Neo4J web browser accessible anywhere. Use only in development environment, this poses a security concern when applied in a production environment.

dbms.connectors.default_listen_address=0.0.0.0

Disable web authentication

01: Edit the neo4j configuration

$ sudo nano /etc/neo4j/neo4j.conf

02: Un-comment the following config to disable authentication. Use only in development environment, this poses a security concern when applied in a production environment.

dbms.security.auth_enabled=false

When commented or have been set to true, accessing the web browser will show the following:

The default password for the neo4j user is neo4j.

When auth_enabled is set to false, the authentication section (username and password) will not be displayed.
