+ 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" <code>mysql> CREATE DATABASE horde; </code> * create a mariadb user with all default privileges on horde.* <code> mysql> create user 'hordeuser'@'%' IDENTIFIED by 'hordepw'; mysql> GRANT ALL on horde.* to 'hordeuser'@'%'; </code> 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. ++ MySQL Horde 6 has been tested with MySQL 8 and MySQL 5.7 versions. Use the "mysql" settings described under MariaDB. ++ Percona Server Horde 6 has not been tested with Percona Server - any Percona 8 release should work. Use the "mysql" settings described under MariaDB. ++ SQLite TBD - untested for H6 except some libraries ++ Postgresql TBD - untested for H6 ++ Oracle TBD - untested for H6
