Getlino and database settings¶

Getlino knows the following Django database engines:

>>> from getlino.utils import DB_ENGINES
>>> import rstgen
>>> cols = "name python_packages service default_port needs_root"
>>> print(rstgen.attrtable(DB_ENGINES, cols))  
============ ================= ============ ============== ============
 name         python_packages   service      default_port   needs_root
------------ ----------------- ------------ -------------- ------------
 mysql        mysqlclient       mysql        3306           True
 postgresql   psycopg2          postgresql   5432           True
 sqlite3                        None                        False
============ ================= ============ ============== ============

A dbengine also has an attribute apt_packages, but we don't print it here because its value can depend on the environment.

Database settings¶

Getlino fills values to the items user, password, password and engine of Django's DATABASES setting.

Multiple database engines on a same server¶

Note that getlino startsite does not install any db engine because this is done by getlino configure.

When you maintain a Lino server, you don't want to decide for each new site which database engine to use. You decide this once during getlino configure. In general, apt-get install is called only during getlino configure, never during getlino startsite. If you have a server with some mysql sites and exceptionally want to install a site with postgres, you simply call getlino configure before calling getlino startsite.

You may use multiple database engines on a same server by running configure between startsite invocations.
