| |
| | | |
− | The OpenStack Dashboard is a reference implementation for the django-nova project. Both are housed on Launchpad.
| + | <!-- #REDIRECT Horizon --> |
| + | == OpenStack Dashboard documentation == |
| | | |
− | To view a quick video tour of the dashboard in action, please see this [http://blog.rabbityard.com/post/2937203639/openstack-dashboard-video blog post].
| + | [http://docs.openstack.org/developer/horizon/ Horizon: The OpenStack Dashboard Project] |
− | | |
− | == Prerequisites for Running The [[OpenStack]] Dashboard ==
| |
− | | |
− | * python 2.6 (not tested with python 3.0)
| |
− | * Running OpenStack nova instance (nova-api and nova-compute) with EC2 API enabled
| |
− | * URL of your nova-api instance (this is usually something like http://localhost:8773/services/Cloud)
| |
− | * Valid nova '''admin''' user name and user credentials (specifically, the username, the NOVA_ACCESS_KEY and NOVA_SECRET_KEY). These should be in your novarc file (where they are called EC2_ACCESS_KEY and EC2_SECRET_KEY) but also can be found in the nova database. You can find instructions for this at [[RunningNova]].
| |
− | | |
− | These instructions have only been tested on Ubuntu 10.10 server.
| |
− | | |
− | == Installation Overview ==
| |
− | | |
− | The overall steps for building the dashboard are:
| |
− | | |
− | # Get the source for both django-nova and openstack-dashboard from launchpad
| |
− | # (OPTIONAL) Build django-nova with the boostrap script and buildout commands as shown in the dajngo-nova README
| |
− | # Build and configure openstack-dashboard
| |
− | # Create the openstack-dashboard database (via the syncdb command)
| |
− | # Run the server
| |
− | | |
− | These instructions are for a '''test''' openstack-dashboard deployment. They configure your dashboard to use a sqlite3 database and the default django server. To create a more robust installation, you should configure this with an Apache webserver and MySQL/Postgres database.
| |
− | | |
− | == Get The Source ==
| |
− | | |
− | To prevent any interruption to our hacking, let's grab all the code that we need.
| |
− | | |
− | === Create Your Source Directory ===
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ mkdir src
| |
− | $ cd src
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | === Get django-nova ===
| |
− | django-nova is the reference implementation of the openstack dashboard. This module contains almost all of the real code of the website.
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ mkdir django-nova
| |
− | $ cd django-nova
| |
− | $ bzr init-repo .
| |
− | $ bzr branch lp:django-nova/trunk
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | You should now have a directory called trunk, which contains the reference implementation.
| |
− | | |
− | === Get openstack-dashboard ===
| |
− | openstack-dashboard provides all the look and feel for the dashboard.
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ cd ..
| |
− | $ mkdir openstack-dashboard
| |
− | $ cd openstack-dashboard
| |
− | $ bzr init-repo .
| |
− | $ bzr branch lp:openstack-dashboard trunk
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | You should now have a directory called trunk, which contains the OpenStack Dashboard application.
| |
− | | |
− | == Build django-nova (OPTIONAL) ==
| |
− | If you want to develop or modify the inner workings of django-nova, complete this step. If not, proceed to the next step.
| |
− | | |
− | We will now build the reference implementation that our OpenStack Dashboard will use.
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ cd ../django-nova/trunk/
| |
− | $ python bootstrap.py
| |
− | $ bin/buildout
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | These two commands (bootstrap.py and buildout) will install all the dependencies of django-nova.
| |
− | | |
− | == Build and Configure openstack-dashboard ==
| |
− | With the reference implementation built, it is now time to configure our OpenStack Dashboard application. The first step in configuring the application is to create your local_settings.py file:
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ cd ../../openstack-dashboard/trunk
| |
− | $ cd local
| |
− | $ cp local_settings.py.example local_settings.py
| |
− | $ vi local_settings.py
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | In the local_settings.py file, we need to change several important options:
| |
− | | |
− | * NOVA_DEFAULT_ENDPOINT : this needs to be set to nova-api instance URL from above. Keep the default ('http://localhost:8773/services/Cloud') if you are running the dashboard on the same machine as your nova-api.
| |
− | * NOVA_ACCESS_KEY : this should be the EC2_ACCESS_KEY in your novarc file.
| |
− | * NOVA_SECRET_KEY : this should be the EC2_SECRET_KEY in your novarc file.
| |
− | * NOVA_ADMIN_USER: this can be any user with admin privileges in your nova database. The CLOUD_SERVERS_USERNAME from your admin credentials file is fine.
| |
− | * NOVA_PROJECT: this can be any project (defined in your nova database) which the NOVA_ADMIN_USER is defined as project_manager. Refer to [[RunningNova]] for assistance if you haven't defined any nova projects.
| |
− | | |
− | Now it's time to install the openstack-dashboard environment. This installs all the dependencies for openstack-dashboard (including the django-nova from earlier).
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ apt-get install -y python-setuptools
| |
− | $ cd ..
| |
− | $ sudo easy_install virtualenv
| |
− | $ python tools/install_venv.py ../../django-nova/trunk
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | This will take a bit as it needs to download a number of dependencies from the internet.
| |
− | | |
− | With that done, let's create the database:
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ tools/with_venv.sh dashboard/manage.py syncdb
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | This will ask you a few questions (follow the instructions within the * * to answer the questions):
| |
− | | |
− | <pre><nowiki>
| |
− | You just installed Django's auth system, which means you don't have any superusers defined.
| |
− | Would you like to create one now? (yes/no): *YES*
| |
− | Username (Leave blank to use 'root'): *ENTER YOUR CLOUD_SERVERS_USERNAME FROM NOVARC*
| |
− | E-mail address: *ENTER YOUR EMAIL ADDRESS*
| |
− | Password: *MAKE UP A PASSWORD*
| |
− | Password (again): *REPEAT YOUR PASSWORD*
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | If everything goes correctly, you shouldn't see any errors. A successful run looks something like this (my dashboard is on the same machine as my nova installation):
| |
− | | |
− | <pre><nowiki>
| |
− | $ tools/with_venv.sh dashboard/manage.py syncdb

− | If you receive errors in this step, check your nova-api.log file (usually /var/log/nova/nova-api.log) for clues. Most likely you are having a mismatch between you username, access keys and project settings.

− | == Run the Server ==
| |
− | | |
− | Now run the built-in server at an unprivileged port so that you can view your results:
| |
− | | |
− | | |
− | <pre><nowiki>
| |
− | $ tools/with_venv.sh dashboard/manage.py runserver 0.0.0.0:8000
| |
− | </nowiki></pre>
| |
− | | |
− | | |
− | Make sure that your firewall isn't blocking TCP/8000 and just point your browser at this server on port 8000. If you are running the server on the same machine as your browser, this would be "http://localhost:8000".
