SQL Database

The Horde 6 Base application can be run without an SQL Database.
Most Horde 6 applications and features cannot be run without an SQL Database.

MariaDB

Horde 6 has been tested with MariaDB 10.8 and MariaDB 10.9 - any MariaDB of the 10.x series should work.

* ensure mariadb uses "innodb" as its default engine
* ensure the PHP server can reach the database hostname and port
* use utf8mb4 as default charset.
* create a database schema. This documentation assumes the db name is "horde"

mysql> CREATE DATABASE horde;

* create a mariadb user with all default privileges on horde.*

mysql> create user 'hordeuser'@'%' IDENTIFIED by 'hordepw';
mysql> GRANT ALL on horde.* to 'hordeuser'@'%';

Do not use the default password shown here. If you run the DB on the same host as horde, use @'localhost' instead of @'%'. If you want to restrict access to a specific IP address or network, consult the database manual.

Use the "mysql" settings described under MariaDB.
