Database Backend
|
||||
----------------
|
||||
|
||||
Multiple database backends are available. The available databases are defined
|
||||
in the lib/databases directory.
|
||||
``mysql`` is the default database, choose a different one by putting the
|
||||
following in the ``localrc`` section::
|
||||
Support for the MySQL database backend is included. Addition database backends
|
||||
may be available via external plugins. Enabling of disabling MySQL is handled
|
||||
via the usual service functions and ``ENABLED_SERVICES``. For example, to
|
||||
disable MySQL in ``local.conf``::
|
||||
|
||||
disable_service mysql
|
||||
enable_service postgresql
|
||||
|
||||
``mysql`` is the default database.
|
||||
|
||||
RPC Backend
|
||||
-----------
|
||||
|
||||
Support for a RabbitMQ RPC backend is included. Additional RPC
|
||||
backends may be available via external plugins. Enabling or disabling
|
||||
RabbitMQ is handled via the usual service functions and
|
||||
``ENABLED_SERVICES``.
