#FlatDB Service Setting up as a service is much more convinient than using screen and auto-restart by loop. FlatDB is using auto-restart and will put logs outside of syslog, for convinience.

First you need to create a new file called flatdb.service in /etc/systemd/system

#systemctl daemon-reload -> After changing service config
#systemctl enable flatdb -> After you create file remember to issue this 

[Unit]
Description=FlatDB K/V datastore server

ExecStart=/bin/sh -c 'cd /home/flatdb/; export GODEBUG=gctrace=1; started=`date --rfc-3339=seconds`; echo Starting Flatdb $started; ./flatdb 1>"log-$started.txt" 2>"error-$started.log.txt";'

[Install]
WantedBy=multi-user.target

Then, create new directory /home/flatdb/

mkdir /home/flatdb/

Copy flatdb server executable, conf.json and server-status.html here, then

cd /home/flatdb/
chmod 0777 ../flatdb
chmod 0777 flatdb

Last step is to reload the systemd config, enable service to be started automatically and start it

systemctl daemon-reload
systemctl enable flatdb
service flatdb start

After this, the service will be started on server boot, and will also automatically re-start in case of failure.
