Modify the MariaDB data directory

The data directory for MariaDB is set to /opt/bitnami/mariadb/data by default. You can modify the location of this folder modifying the /opt/bitnami/mariadb/my.cnf file, as shown below:

...
datadir=/opt/bitnami/mariadb/data
...

Also modify the /opt/bitnami/mariadb/scripts/ctl.sh file to reflect the new directory location:

--datadir=/opt/bitnami/mariadb/data

Finally, move the data/ directory to the new location and restart the database.
