How to start the server
|
|
=======================
|
|
|
|
Web service
|
|
===========
|
|
|
|
You can start the default web server bundled in Tryton with this command line::
|
|
|
|
trytond -c <config file>
|
|
|
|
The server will wait for client connections on the interface defined in the
|
|
``web`` section of the :ref:`configuration <topics-configuration>`.
|
|
|
|
.. note:: When using multiple config files the order is importart as last
|
|
entered files will override the items of first files
|
|
|
|
WSGI server
|
|
-----------
|
|
|
|
If you prefer to run Tryton inside your own WSGI server instead of the simple
|
|
server of Werkzeug, you can use the application ``trytond.application.app``.
|
|
Following environment variables can be set:
|
|
|
|
* ``TRYTOND_CONFIG``: Point to :ref:`configuration <topics-configuration>`
|
|
file.
|
|
* ``TRYTOND_LOGGING_CONFIG``: Point to :ref:`logging <topics-logs>` file.
|
|
* ``TRYTOND_LOGGING_LEVEL``: An integer to set the default `logging level`_
|
|
(default: ``ERROR``).
|
|
* ``TRYTOND_COROUTINE``: Use coroutine for concurrency.
|
|
* ``TRYTOND_DATABASE_NAMES``: A list of database names in CSV format, using
|
|
python default dialect.
|
|
|
|
.. warning:: You must manage to serve the static files from the web root.
|
|
|
|
.. _`logging level`: https://docs.python.org/library/logging.html#logging-levels
|
|
|
|
Coroutine server
|
|
----------------
|
|
|
|
The Werkzeug server uses thread for concurrency. This is not optimal for the
|
|
long-polling request on the :ref:`bus <ref-bus>` as each client consumes
|
|
permanently one thread.
|
|
You can start the server with coroutine using the option ``--coroutine``.
|
|
|
|
Cron service
|
|
============
|
|
|
|
If you want to run some :ref:`scheduled actions <topics-cron>`, you must also
|
|
run the cron server with this command line::
|
|
|
|
trytond-cron -c <config file> -d <database>
|
|
|
|
The server will wake up every minutes and preform the scheduled actions defined
|
|
in the ``database``.
|
|
You can also launch the command every few minutes from a scheduler with the
|
|
option ``--once``.
|
|
|
|
Worker service
|
|
==============
|
|
|
|
If you want to use a pool of workers to run :ref:`asynchronously some tasks
|
|
<topics-task-queue>`, you must activate the worker in the ``queue`` section of
|
|
the :ref:`configuration <topics-configuration>` and run the worker manager with
|
|
this command line::
|
|
|
|
trytond-worker -c <config file> -d <database>
|
|
|
|
The manager will dispatch tasks from the queue to a pool of worker processes.
|
|
|
|
Services options
|
|
================
|
|
|
|
You will find more options for those services by using ``--help`` arguments.
