Configure the dashboard

1. Specify the host for your OpenStack Identity Service endpoint in the /etc/openstack-dashboard/local_settings.py file with the OPENSTACK_HOST setting.

   The following example shows this setting:

   import os
   
   from django.utils.translation import ugettext_lazy as _
   
   DEBUG = False
   TEMPLATE_DEBUG = DEBUG
   PROD = True
   USE_SSL = False
   
   SITE_BRANDING = 'OpenStack Dashboard'
   
   # Ubuntu-specific: Enables an extra panel in the 'Settings' section
   # that easily generates a Juju environments.yaml for download,
   # preconfigured with endpoints and credentials required for bootstrap
   # and service deployment.
   ENABLE_JUJU_PANEL = True
   
   # Note: You should change this value
   SECRET_KEY = 'elj1IWiLoWHgryYxFT6j7cM5fGOOxWY0'
   
   # Specify a regular expression to validate user passwords.
   # HORIZON_CONFIG = {
   #     "password_validator": {
   #         "regex": '.*',
   #         "help_text": _("Your password does not meet the requirements.")
   #     }
   # }
   
   LOCAL_PATH = os.path.dirname(os.path.abspath(__file__))
   
   CACHES = {
   	'default': {
   		'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
   		'LOCATION' : '127.0.0.1:11211'
   	}
   }
   
   # Send email to the console by default
   EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
   # Or send them to /dev/null
   #EMAIL_BACKEND = 'django.core.mail.backends.dummy.EmailBackend'
   
   # Configure these for your outgoing email host
   # EMAIL_HOST = 'smtp.my-company.com'
   # EMAIL_PORT = 25
   # EMAIL_HOST_USER = 'djangomail'
   # EMAIL_HOST_PASSWORD = 'top-secret!'
   
   # For multiple regions uncomment this configuration, and add (endpoint, title).
   # AVAILABLE_REGIONS = [
   #     ('http://cluster1.example.com:5000/v2.0', 'cluster1'),
   #     ('http://cluster2.example.com:5000/v2.0', 'cluster2'),
   # ]
   
   OPENSTACK_HOST = "127.0.0.1"
   OPENSTACK_KEYSTONE_URL = "http://%s:5000/v2.0" % OPENSTACK_HOST
   OPENSTACK_KEYSTONE_DEFAULT_ROLE = "Member"
   
   # The OPENSTACK_KEYSTONE_BACKEND settings can be used to identify the
   # capabilities of the auth backend for Keystone.
   # If Keystone has been configured to use LDAP as the auth backend then set
   # can_edit_user to False and name to 'ldap'.
   #
   # TODO(tres): Remove these once Keystone has an API to identify auth backend.
   OPENSTACK_KEYSTONE_BACKEND = {
       'name': 'native',
       'can_edit_user': True
   }
   
   # OPENSTACK_ENDPOINT_TYPE specifies the endpoint type to use for the endpoints
   # in the Keystone service catalog. Use this setting when Horizon is running
   # external to the OpenStack environment. The default is 'internalURL'.
   #OPENSTACK_ENDPOINT_TYPE = "publicURL"
   
   # The number of Swift containers and objects to display on a single page before
   # providing a paging element (a "more" link) to paginate results.
   API_RESULT_LIMIT = 1000
   
   # If you have external monitoring links, eg:
   # EXTERNAL_MONITORING = [
   #     ['Nagios','http://foo.com'],
   #     ['Ganglia','http://bar.com'],
   # ]
   
   LOGGING = {
           'version': 1,
           # When set to True this will disable all logging except
           # for loggers specified in this configuration dictionary. Note that
           # if nothing is specified here and disable_existing_loggers is True,
           # django.db.backends will still log unless it is disabled explicitly.
           'disable_existing_loggers': False,
           'handlers': {
               'null': {
                   'level': 'DEBUG',
                   'class': 'django.utils.log.NullHandler',
                   },
               'console': {
                   # Set the level to "DEBUG" for verbose output logging.
                   'level': 'INFO',
                   'class': 'logging.StreamHandler',
                   },
               },
           'loggers': {
               # Logging from django.db.backends is VERY verbose, send to null
               # by default.
               'django.db.backends': {
                   'handlers': ['null'],
                   'propagate': False,
                   },
               'horizon': {
                   'handlers': ['console'],
                   'propagate': False,
               },
               'novaclient': {
                   'handlers': ['console'],
                   'propagate': False,
               },
               'keystoneclient': {
                   'handlers': ['console'],
                   'propagate': False,
               },
               'nose.plugins.manager': {
                   'handlers': ['console'],
                   'propagate': False,
               }
           }
   }
   

   The service catalog configuration in the Identity Service determines whether a service appears in the dashboard. For the full listing, see Horizon Settings and Configuration.

2. Restart Apache http server. For Ubuntu/Debian/SUSE:

   # service apache2 restart

   or for Fedora/RHEL/CentOS:

   # service httpd restart

   Next, restart memcached:

   # service memcached restart

This example uses the http://openstack.example.com domain. Use a domain that fits your current setup.

1. In the /etc/openstack-dashboard/local_settings.py file, update the following options:

   USE_SSL = True
   CSRF_COOKIE_SECURE = True
   SESSION_COOKIE_SECURE = True
   SESSION_COOKIE_HTTPONLY = True

   To enable HTTPS, the USE_SSL = True option is required.

   The other options require that HTTPS is enabled; these options defend against cross-site scripting.

2. Edit the /etc/apache2/ports.conf file and add the following line:

   NameVirtualHost *:443

3. Edit the /etc/apache2/conf.d/openstack-dashboard.conf file as shown in Example 3.2, “After”:

    

   Example 3.1. Before

   WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
   WSGIDaemonProcess horizon user=www-data group=www-data processes=3 threads=10
   Alias /static /usr/share/openstack-dashboard/openstack_dashboard/static/
   <Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi>
   # For Apache http server 2.2 and earlier:
   Order allow,deny
   Allow from all
   
   # For Apache http server 2.4 and later:
   # Require all granted
   </Directory>

   
   
    

   Example 3.2. After

   <VirtualHost *:80>
   ServerName openstack.example.com
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteCond %{HTTPS} off
   RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
   </IfModule>
   <IfModule !mod_rewrite.c>
   RedirectPermanent / https://openstack.example.com
   </IfModule>
   </VirtualHost>
   <VirtualHost *:443>
   ServerName openstack.example.com
   
   SSLEngine On
   # Remember to replace certificates and keys with valid paths in your environment
   SSLCertificateFile /etc/apache2/SSL/openstack.example.com.crt
   SSLCACertificateFile /etc/apache2/SSL/openstack.example.com.crt
   SSLCertificateKeyFile /etc/apache2/SSL/openstack.example.com.key
   SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
   
   # HTTP Strict Transport Security (HSTS) enforces that all communications
   # with a server go over SSL. This mitigates the threat from attacks such
   # as SSL-Strip which replaces links on the wire, stripping away https prefixes
   # and potentially allowing an attacker to view confidential information on the
   # wire
   Header add Strict-Transport-Security "max-age=15768000"
   
   WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
   WSGIDaemonProcess horizon user=www-data group=www-data processes=3 threads=10
   Alias /static /usr/share/openstack-dashboard/openstack_dashboard/static/
   <Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi>
   # For Apache http server 2.2 and earlier:
   Order allow,deny
   Allow from all
   
   # For Apache http server 2.4 and later:
   # Require all granted
   </Directory>
   </VirtualHost>

   
   

   In this configuration, the Apache HTTP server listens on port 443 and redirects all non-secure requests to the HTTPS protocol. The secured section defines the private key, public key, and certificate to use.

4. Restart the Apache HTTP server.

   For Debian, Ubuntu, or SUSE distributions:

   # service apache2 restart

   For Fedora, RHEL, or CentOS distributions:

   # service httpd restart

5. Restart memcached:

   # service memcached restart

   If you try to access the dashboard through HTTP, the browser redirects you to the HTTPS page.

1. Edit /usr/share/pyshared/horizon/dashboards/nova/instances/templates/instances/_detail_vnc.html.

2. Modify the width and height parameters, as follows:

   <iframe src="{{ vnc_url }}" width="720" height="430"></iframe>
