However, you have to configure it by hand:
* set up a mysql database and user to access it:  hda-create-db-and-user greyhole
* load the schema
  mysql -u greyhole -pgreyhole  greyhole < /usr/share/greyhole/schema-mysql.sql* initialize the basic settings for Greyhole: configure /etc/greyhole.conf appropriately (that is up to your configuration)* enable permanently and start the greyhole service:  systemctl enable greyhole.service  systemctl start greyhole.service
