Deploying Wagtail
|
|
-----------------
|
|
|
|
On your server
|
|
~~~~~~~~~~~~~~
|
|
|
|
Wagtail is straightforward to deploy on modern Linux-based distributions, but see the section on :doc:`performance </advanced_topics/performance>` for the non-Python services we recommend.
|
|
|
|
Our current preferences are for Nginx, Gunicorn and supervisor on Debian, but Wagtail should run with any of the combinations detailed in Django's `deployment documentation <https://docs.djangoproject.com/en/dev/howto/deployment/>`_.
|
|
|
|
On PythonAnywhere
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
`PythonAnywhere <https://www.pythonanywhere.com/>`_ is a Platform-as-a-Service (PaaS) focused on Python hosting and development. It allows developers to quickly develop, host, and scale applications in a cloud environment. Starting with a free plan they also provide MySQL and PostgreSQL databases as well as very flexible and affordable paid plans, so there's all you need to host a Wagtail site. To get quickly up and running you may use the `wagtail-pythonanywhere-quickstart <https://github.com/texperience/wagtail-pythonanywhere-quickstart>`_.
|
|
|
|
On other PAASs and IAASs
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
We know of Wagtail sites running on `Heroku <http://spapas.github.io/2014/02/13/wagtail-tutorial/>`_, Digital Ocean and elsewhere. If you have successfully installed Wagtail on your platform or infrastructure, please :doc:`contribute </contributing/index>` your notes to this documentation!
|
|
|
|
Cloud storage
|
|
~~~~~~~~~~~~~
|
|
|
|
Wagtail follows `Django's conventions for managing uploaded files <https://docs.djangoproject.com/en/2.0/topics/files/>`_, and can be configured to store uploaded images and documents on a cloud storage service such as Amazon S3; this is done through the `DEFAULT_FILE_STORAGE <https://docs.djangoproject.com/en/2.0/ref/settings/#std:setting-DEFAULT_FILE_STORAGE>`_ setting in conjunction with an add-on package such as `django-storages <https://django-storages.readthedocs.io/>`_. Be aware that setting up remote storage will not entirely offload file handling tasks from the application server - some Wagtail functionality requires files to be read back by the application server. In particular, documents are served through a Django view in order to enforce permission checks, and original image files need to be read back whenever a new resized rendition is created.
|
|
|
|
Note that the django-storages Amazon S3 backends (``storages.backends.s3boto.S3BotoStorage`` and ``storages.backends.s3boto3.S3Boto3Storage``) **do not correctly handle duplicate filenames** in their default configuration. When using these backends, ``AWS_S3_FILE_OVERWRITE`` must be set to ``True``.
|
|
|
|
If you are also serving Wagtail's static files from remote storage (using Django's `STATICFILES_STORAGE <https://docs.djangoproject.com/en/2.0/ref/settings/#std:setting-STATICFILES_STORAGE>`_ setting), you'll need to ensure that it is configured to serve `CORS HTTP headers <https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS>`_, as current browsers will reject remotely-hosted font files that lack a valid header. For Amazon S3, refer to the documentation `Setting Bucket and Object Access Permissions <https://docs.aws.amazon.com/AmazonS3/latest/user-guide/set-permissions.html>`_, or (for the ``storages.backends.s3boto.S3BotoStorage`` backend only) add the following to your Django settings:
|
|
|
|
.. code-block:: python
|
|
|
|
AWS_HEADERS = {
|
|
'Access-Control-Allow-Origin': '*'
|
|
}
|
|
|
|
For other storage services, refer to your provider's documentation, or the documentation for the Django storage backend library you're using.
