SHRINE utilizes MySQL in the form of MariaDB, a relational database management system, and uses MySQL as a default. In order to set that up on your system, you will first need to install MariaDB. For more information on MariaDB, please visit:

$ yum -y install mariadb-server

-- Start service
$ systemctl start mariadb

-- Enable on boot
$ systemctl enable mariadb

After this, you will need to create the SHRINE database user and grant it full access:

$ mysql -u root

mysql> CREATE USER 'shrine'@'localhost' IDENTIFIED BY 'demouser';
mysql> GRANT ALL privileges ON *.* TO 'shrine'@'localhost';
mysql> \q
