Introduction

Neo4j is a powerful graph database management system that allows you to store and query data in the form of graphs. This guide will walk you through the installation and configuration of Neo4j on Ubuntu 22.04, which can be effectively hosted on a Windows VPS UK for optimal performance and scalability.

Prerequisites

• An Ubuntu 22.04 server with root access
• Basic knowledge of Linux commands
• Java installed on your server (Java 11 or higher is recommended)

Step 1: Update Your System

Begin by updating your package index and upgrading any existing packages:

sudo apt update && sudo apt upgrade -y

Step 2: Install Java

To install Java, use the following command:

sudo apt install openjdk-11-jdk -y

Verify the installation:

java -version

Step 3: Add the Neo4j Repository

Add the Neo4j repository to your system:

echo "deb https://debian.neo4j.com/ stable 3.5" | sudo tee /etc/apt/sources.list.d/neo4j.list

Import the Neo4j GPG key:

wget -O - https://debian.neo4j.com/neo4j.asc | sudo apt-key add -

Step 4: Install Neo4j

Step 6: Configure Neo4j

To configure Neo4j, open the configuration file:

sudo nano /etc/neo4j/neo4j.conf

You can set your database path, memory settings, and other configurations in this file. For instance, to allow remote access, uncomment and modify the following line:

Save and close the file after making your changes.
