In some environments, users are required to run Neo4j on ports lower than 1024 due to corporate policies. The following is a sample configuration showing how to configure Neo4j 3.5 and newer to listen on those ports.

Refer to a path/to/file.

  1. Configure neo4j.conf to set the http, https and bolt ports.

On a debian installation it would look like this:

In the /etc/neo4j/pre-neo4j.sh file, configure this as follows:

# HTTPS
echo "dbms_connector_https_enabled" "${dbms_connector_https_enabled:=true}"
echo "dbms_connector_https_listen_address" "${dbms_connector_https_listen_address:=0.0.0.0:80}"

# HTTP
echo "dbms_connector_http_enabled" "${dbms_connector_http_enabled:=false}"
echo "dbms_connector_http_listen_address" "${dbms_connector_http_listen_address:=0.0.0.0:7474}"

# BOLT
echo "dbms_connector_bolt_enabled" "${dbms_connector_bolt_enabled:=true}"
echo "dbms_connector_bolt_listen_address" "${dbms_connector_bolt_listen_address:=0.0.0.0:8080}"
echo "dbms_connector_bolt_tls_level" "${dbms_connector_bolt_tls_level:=REQUIRED}"

On a tar installation it would look like this:

# Bolt connector
dbms.connector.bolt.enabled=true
#dbms.connector.bolt.tls_level=OPTIONAL
dbms.connector.bolt.listen_address=:8080

# HTTP Connector. There can be zero or one HTTP connectors.
dbms.connector.http.enabled=false
#dbms.connector.http.listen_address=:7474

# HTTPS Connector. There can be zero or one HTTPS connectors.
dbms.connector.https.enabled=true
dbms.connector.https.listen_address=:80

2) Identify the location of the java installation.

readlink -f $(which java)

3) Bind the java executable to the privileged ports (use the path found in step 2).

sudo setcap cap_net_bind_service=+eip /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

4) Neo4j should start and allow access via https on port 80.
