There's a lot of these, so doing them in chunks. This fixes the custom roles. Remove the git and jjb docs, since we don't use them anymore. Change-Id: I0c5b74f7b73315dac93bce6be0d920cddb94fb58

Overview
|
|
========
|
|
|
|
The site ask.openstack.org based on the officially released askbot pip distribution.
|
|
The stable deployment is extended with a custom OpenStack theme available at
|
|
https://opendev.org/opendev/askbot-theme.
|
|
|
|
The ask-staging.openstack.org site based on master branch of
|
|
https://github.com/askbot/askbot-devel repository, and deploys askbot
|
|
directly from github and consume the openstack theme from
|
|
openstack-infra/askbot-theme repository. The staging site is using
|
|
python virtualenv for proper pip dependency handling.

|
|
Apache / mod_wsgi
|
|
-----------------
|
|
|
|
Serve the incoming http request using the mod_wsgi Python WSGI adapter, through
|
|
an SSL virtual host. The site vhost also contains url aliases to serve static
|
|
content of the theme and all uploaded image files, including the site logo.
|
|
|
|
Askbot site
|
|
-----------
|
|
|
|
The Askbot django application, the custom site specific assets live under
|
|
/srv/askbot-sites/slot0 directory, including the configuration, application
|
|
level log files, static content, custom OpenStack theme and uploaded files.
|
|
|
|
The authentication based on Google, Yahoo and Launchpad OpenID providers.
|
|
Local login and all other providers except Google, Yahoo and Launchpad are
|
|
disabled in site configuration.
|
|
|
|
The askbot-theme repository contains just the pure Sass source of the theme,
|
|
so this must be precompiled by compass Sass tool.
|
|
|
|
Application management tool can be found under /srv/askbot-sites/slot0/config:
|
|
``python manage.py <command>``
|
|
|
|
Configuration files:
|
|
|
|
* :cgit_file:`modules/askbot/templates/askbot.vhost.erb`
|
|
* :cgit_file:`modules/askbot/templates/settings.py.erb`
|
|
|
|
In addition to the file-based configuration, Askbot provides a web interface
|
|
to tweak its own settings. Toggles and fields for reputation thresholds,
|
|
user communications rules, data entry and formatting rules, keys for external
|
|
services and static content can be found at `$URL/en/settings/`.
|
|
|
|
As per Django standard, `$URL/admin` provides access to the Django
|
|
administration interface. Effectively a limited web portal to the data in the
|
|
database - but sometimes useful for debugging login problems using the
|
|
`Django_authopenid` plugin.
|
|
|
|
|
|
Celery daemon
|
|
-------------
|
|
|
|
This upstart based daemon is responsible for async tasks of the Askbot site,
|
|
and can be managed by standard service management tools:
|
|
``server askbot-celeryd <start|stop|status>``
|
|
|
|
Redis
|
|
-----
|
|
|
|
Askbot is using redis for handling local caching of configuration and page
|
|
data. It is useful to clear the redis cache with the ``FLUSHALL`` command
|
|
after a service restart.
|
|
|
|
Postgresql
|
|
----------
|
|
|
|
A postgresql database hosts the content and dynamic site configuration.
|
|
|
|
Apache Solr
|
|
-----------
|
|
|
|
Apache Solr handling the full-text indexes of the site, based on a
|
|
multi-core setup, and assigning cores for specific languages. Currently
|
|
the English (en) and Chinese (zh) languages are supported.
|
|
|
|
Solr schema templates can be found at:
|
|
|
|
* :cgit_file:`modules/askbot/templates/solr/schema.en.xml.erb`
|
|
* :cgit_file:`modules/askbot/templates/solr/schema.cn.xml.erb`

Operational notes
|
|
=================
|
|
|
|
The askbot website contains a ``surprisingly`` askbot based support forum,
|
|
and a lot of operational related information is available there. Additional
|
|
maintenance commands:
|
|
|
|
* activate virtualenv: ``source /usr/askbot-env/bin/activate``
|
|
* synchronize db schema: ``python manage.py syncdb``
|
|
* migrate database between upgrades: ``python manage.py migrate``
|
|
* rebuild solr index: ``python manage.py askbot_rebuild_index -l <language-code>``
|
|
* assign administrator right to a user: ``python manage.py add_admin <user-id>``
|
|
* update site url setting in askbot database: ``update livesettings_setting set value = '<site-url>' where "group" = 'QA_SITE_SETTINGS' and key = 'APP_URL';``
