System Requirements
|
|
===================
|
|
|
|
* Python 2.7
|
|
* Django 1.7 or 1.8
|
|
* Minimum required set of running OpenStack services are:
|
|
|
|
* nova: OpenStack Compute
|
|
* keystone: OpenStack Identity
|
|
* glance: OpenStack Image service
|
|
* neutron: OpenStack Networking (unless nova-network is used)
|
|
|
|
* All other services are optional.
|
|
Horizon supports the following services in the Juno release.
|
|
If the keystone endpoint for a service is configured,
|
|
horizon detects it and enables its support automatically.
|
|
|
|
* swift: OpenStack Object Storage
|
|
* cinder: OpenStack Block Storage
|
|
* heat: Orchestration
|
|
* ceilometer: Telemetry
|
|
* trove: Database service for OpenStack
|
|
* sahara: Data processing service for OpenStack
|
|
|
|
Installation
|
|
============
|
|
|
|
1. Compile translation message catalogs for internationalization.
|
|
This step is not required if you do not need to support languages
|
|
other than English. GNU ``gettext`` tool is required to compile
|
|
message catalogs::
|
|
|
|
$ sudo apt-get install gettext
|
|
$ ./run_tests.sh --compilemessages
|
|
|
|
This command compiles translation message catalogs within Python
|
|
virtualenv named ``.venv``. After this step, you can remove
|
|
``.venv`` directory safely.
|
|
|
|
2. Install the horizon python module into your system. Run the following
|
|
in the top directory::
|
|
|
|
$ sudo pip install .
|
|
|
|
3. Create ``openstack_dashboard/local/local_settings.py``.
|
|
It is usually a good idea to copy
|
|
``openstack_dashboard/local/local_settings.py.example`` and edit it.
|
|
At least we need to customize the following variables in this file.
|
|
|
|
* ``ALLOWED_HOSTS`` (unless ``DEBUG`` is ``True``)
|
|
* ``OPENSTACK_KEYSTONE_URL``
|
|
|
|
For more details, please refer to :doc:`deployment` and :doc:`settings`.
|
|
|
|
4. Optional: Django has a compressor feature that performs many enhancements
|
|
for the delivery of static files, including standardization and
|
|
minification/uglification. This processing can be run either online or
|
|
offline (pre-processed). Letting the compression process occur at runtime
|
|
will incur processing and memory use when the resources are first requested;
|
|
doing it ahead of time removes those runtime penalties.
|
|
|
|
If you want the static files to be processed before server runtime, you'll
|
|
need to configure your local_settings.py to specify
|
|
``COMPRESS_OFFLINE = True``, then run the following commands::
|
|
|
|
$ ./manage.py collectstatic
|
|
$ ./manage.py compress
|
|
|
|
5. Set up a web server with WSGI support.
|
|
It is optional but recommended in production deployments.
|
|
For example, install Apache web server on Ubuntu::
|
|
|
|
$ sudo apt-get install apache2 libapache2-mod-wsgi
|
|
|
|
You will either use the provided ``openstack_dashboard/wsgi/django.wsgi`` or
|
|
generate an ``openstack_dashboard/wsgi/horizon.wsgi`` file with the
|
|
following command (which detects if you use a virtual environment or not to
|
|
automatically build an adapted wsgi file)::
|
|
|
|
$ ./manage.py make_web_conf --wsgi
|
|
|
|
Then configure the web server to host OpenStack dashboard via WSGI.
|
|
For apache2 web server, you may need to create
|
|
``/etc/apache2/sites-available/horizon.conf``.
|
|
The template in devstack is a good example of the file.
|
|
http://git.openstack.org/cgit/openstack-dev/devstack/tree/files/apache-horizon.template
|
|
Or, if you previously generated an ``openstack_dashboard/wsgi/horizon.wsgi``
|
|
you can automatically generate an apache configuration file::
|
|
|
|
$ ./manage.py make_web_conf --apache > /etc/apache2/sites-available/horizon.conf
|
|
|
|
Same as above but if you want ssl support:
|
|
|
|
$ ./manage.py make_web_conf --apache --ssl --sslkey=/path/to/ssl/key --sslcert=/path/to/ssl/cert > /etc/apache2/sites-available/horizon.conf
|
|
|
|
6. Finally, enable the above configuration and restart the web server::
|
|
|
|
$ sudo a2ensite horizon
|
|
$ sudo service apache2 restart
|
|
|
|
