Deploying Wagtail ----------------- On your server ~~~~~~~~~~~~~~ Wagtail is straightforward to deploy on modern Linux-based distributions, but see the section on :doc:`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 :doc:`deployment documentation `. On Divio Cloud ~~~~~~~~~~~~~~ `Divio Cloud `_ is a Dockerised cloud hosting platform for Python/Django that allows you to launch and deploy Wagtail projects in minutes. With a free account, you can create a Wagtail project. Choose from a: * `site based on the Wagtail Bakery project `_, or * `brand new Wagtail project `_ (see the `how to get started notes `_). Divio Cloud also hosts a `live Wagtail Bakery demo `_ (no account required). On PythonAnywhere ~~~~~~~~~~~~~~~~~ `PythonAnywhere `_ 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 `_. On other PAASs and IAASs ~~~~~~~~~~~~~~~~~~~~~~~~ We know of Wagtail sites running on `Heroku `_, Digital Ocean and elsewhere. If you have successfully installed Wagtail on your platform or infrastructure, please :doc:`contribute ` your notes to this documentation! Deployment tips ~~~~~~~~~~~~~~~ Static files ++++++++++++ As with all Django projects, static files are not served by the Django application server in production (i.e. outside of the ``manage.py runserver`` command); these need to be handled separately at the web server level. See :doc:`Django's documentation on deploying static files `. The JavaScript and CSS files used by the Wagtail admin frequently change between releases of Wagtail - it's important to avoid serving outdated versions of these files due to browser or server-side caching, as this can cause hard-to-diagnose issues. We recommend enabling :class:`~django.contrib.staticfiles.storage.ManifestStaticFilesStorage` in the ``STATICFILES_STORAGE`` setting - this ensures that different versions of files are assigned distinct URLs. Cloud storage +++++++++++++ Wagtail follows :doc:`Django's conventions for managing uploaded 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 `_ setting in conjunction with an add-on package such as `django-storages `_. 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 ``False``. If you are also serving Wagtail's static files from remote storage (using Django's `STATICFILES_STORAGE `_ setting), you'll need to ensure that it is configured to serve `CORS HTTP headers `_, 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 `_, 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.
