Review and update the deploment docs for Debian 10 and CentOS 8 [#5593].

Mostly a thorough test and cleanup. The significant change is moving the systemd
config into the deployment docs an the registration/security considerations to
production considerations docs.

Deploying MediaGoblin
=====================
GNU MediaGoblin is fairly new, and so at the time of writing there aren't
easy package-manager-friendly methods to install it. However, doing a basic
install isn't too complex in and of itself. Following this deployment guide
will take you step-by-step through setting up your own instance of MediaGoblin.
Following this deployment guide will take you step-by-step through
setting up your own instance of MediaGoblin.
Of course, when it comes to setting up web applications like MediaGoblin,
there's an almost infinite way to deploy things, so for now, we'll keep it
simple with some assumptions. We recommend a setup that combines MediaGoblin +
virtualenv + Waitress + Nginx on a .deb- or .rpm-based GNU/Linux distro.
MediaGoblin most likely isn't yet available from your operating
system's package manage, however, a basic install isn't too complex in
and of itself. We recommend a setup that combines
MediaGoblin, virtualenv, Waitress and Nginx on a .deb or .rpm-based
GNU/Linux distribution.
Other deployment options (e.g., deploying on FreeBSD, Arch Linux, using
Apache, etc.) are possible, though! If you'd prefer a different deployment
approach, see our
`Deployment wiki page <http://wiki.mediagoblin.org/Deployment>`_.
Experts may of course choose other deployment options, including
Apache. See our `Deployment wiki page
<http://wiki.mediagoblin.org/Deployment>`_ for for more details.
Please note that we are not able to provide support for these
alternative deployment options.

Run MediaGoblin as a system service
-----------------------------------
To ensure MediaGoblin is automatically started and restarted in case of
problems, we need to run it as a system service. If your operating system uses
Systemd, you can use Systemd ``service files`` to manage both the Celery and
Paste processes.
Place the following service files in the ``/etc/systemd/system/``
directory. The first file should be named
``mediagoblin-celeryd.service``. Be sure to modify it to suit your
environment's setup:
.. code-block:: bash
# Set the WorkingDirectory and Environment values to match your environment.
[Unit]
Description=MediaGoblin Celeryd
[Service]
User=mediagoblin
Group=mediagoblin
Type=simple
WorkingDirectory=/srv/mediagoblin.example.org/mediagoblin
Environment=MEDIAGOBLIN_CONFIG=/srv/mediagoblin.example.org/mediagoblin/mediagoblin.ini \
CELERY_CONFIG_MODULE=mediagoblin.init.celery.from_celery

--logfile=/var/log/mediagoblin/celery.log \
--loglevel=INFO
[Install]
WantedBy=multi-user.target
The second file should be named ``mediagoblin-paster.service``:
.. code-block:: bash
# Set the WorkingDirectory and Environment values to match your environment.

Description=Mediagoblin
[Service]

--log-file=/var/log/mediagoblin/mediagoblin.log \
--server-name=main
[Install]
WantedBy=multi-user.target
Enable these processes to start at boot by entering::
sudo systemctl enable mediagoblin-celeryd.service && sudo systemctl enable mediagoblin-paster.service
Start the processes for the current session with::
sudo systemctl start mediagoblin-celeryd.service
sudo systemctl start mediagoblin-paster.service
If either command above gives you an error, you can investigate the cause of
the error by entering either of::
sudo systemctl status mediagoblin-celeryd.service
sudo systemctl status mediagoblin-paster.service
The above ``systemctl status`` command is also useful if you ever want to
confirm that a process is still running. If you make any changes to the service
files, you can reload the service files by entering::
sudo systemctl daemon-reload
After entering that command, you can attempt to start the Celery or Paste
processes again using ``restart`` instead of ``start``.
Assuming the above was successful, you should now have a MediaGoblin
server that will continue to operate, even after being restarted.

If the contents gets leaked nevertheless, delete your file
and restart the server, so that it creates a new secret key.
All previous sessions will be invalidated.

Use Systemd service files
-------------------------
If your operating system uses Systemd, you can use Systemd ``service files``
to manage both the Celery and Paste processes. Place the following service
files in the ``/etc/systemd/system/`` directory.
The first file should be named ``mediagoblin-celeryd.service``. Be sure to
modify it to suit your environment's setup:
.. code-block:: bash
# Set the WorkingDirectory, Environment and ExecStart values to match your environment.
# If using Debian/Ubuntu, mkdir and chown are located in /bin/mkdir and /bin/chown, respectively.
# If using Fedora/CentOS/Red Hat, mkdir and chown are located in /usr/bin/mkdir and /usr/bin/chown, respectively.

Enable these processes to start at boot by entering::
sudo systemctl enable mediagoblin-celeryd.service && sudo systemctl enable mediagoblin-paster.service
Start the processes for the current session with::
sudo systemctl start mediagoblin-paster.service
sudo systemctl start mediagoblin-celeryd.service
If either command above gives you an error, you can investigate the cause of
the error by entering::
sudo systemctl status mediagoblin-celeryd.service or
sudo systemctl status mediagoblin-paster.service
The above ``systemctl status`` command is also useful if you ever want to
confirm that a process is still running. If you make any changes to the service
files, you can reload the service files by entering::
sudo systemctl daemon-reload
After entering that command, you can attempt to start the Celery or Paste
processes again.
