echo 'deb https://debian.neo4j.com stable 5' | sudo tee /etc/apt/sources.list.d/neo4j.list
sudo apt update
sudo apt install neo4j

Enable Extensions (APOC & GDS)

sudo chown neo4j:neo4j /var/lib/neo4j/plugins/apoc-5.26.0-core.jar

Server Configuration

Edit /etc/neo4j/neo4j.conf to enable remote access and security allowlists:

Expose the Bolt protocol and Web UI ports:

sudo ufw allow 7474/tcp
sudo ufw allow 7687/tcp

4. Service Management

Initialize and verify the Neo4j background process:

sudo systemctl enable neo4j
sudo systemctl start neo4j
sudo systemctl status neo4j --no-pager -l

5. Customizing Ingestion Paths

To import from a large shared volume, modify the import directory in neo4j.conf:
