Resolution

Below are the steps to change the Neo4j port. In this example we arechanging it to 5001.

On the ansible host, run the following command to stop the services.

ansible-playbook -i inventory -K provisioning/services_stop.yaml

On the topology host, open the <install_directory>/netops-topology/neo4j/conf/neo4j.conf file and add the below to the bottom of the file:

server.discovery.listen_address=:5001
server.discovery.advertised_address=:5001

Save the file and then run the below command back on the ansible host to start the services.

ansible-playbook -i inventory -K provisioning/services_start.yaml
