systemd Neo4j service on Ubuntu

systemd ships as the default process manager on Ubuntu 15; get the neo4j systemd service file to install and learn about the configuration. systemd has a lot of great features and I encourage you to check it out as it’s a big improvement IMO from SystemV and Upstart. If you’ve started working with systemd to manage your neo4j process, then you

might have stumble through the new setup. Here are a couple things I found helpful and some config that might get you moving along faster. I won’t go into detail on how to install services with systemd but it basically breaks down into these steps:

1.  Save service file:   /lib/systemd/system/neo4j.services 
2.  Reload config:  sudo systemctl daemon-reload 
3.  Enable on startup:  sudo systemctl enable neo4j.service
