Start a server (eg. based on Ubuntu 17.10)

Basic system setup

sudo su

metachris

# Systemd service config file for pyapi, to run as user 'node', group 'node' and in `/server/neo-python`
# https://www.freedesktop.org/software/systemd/man/systemd.exec.html
#
# Instructions:
# 1. Adapt this file if and as needed (directories, user, group)
# 2. Save this file in /etc/systemd/system/pyapi.service
# 3. Enable the service with `systemctl enable pyapi`
#
# Now you can use systemctl to check status, start stop and restart the service: 
# `systemctl status|start|stop|restart pyapi`
