Database

  • MariaDB 10.1+

The database user requires following privileges:

  • SELECT
  • INSERT
  • DELETE
  • UPDATE
  • CREATE
  • ALTER
  • INDEX
  • DROP
  • REFERENCES
caution

MyISAM is not supported due to the lack of foreign keys.

Shell Access

Although the installation and most parts of the configuration can be carried out without a shell access, it's highly recommended to enable shell access (e.g. ssh) in order to facilitate the comand line interface.

The command line interface provides important features, which are used to maintain and troubleshoot the software.
