Install and configure for openSUSE and SUSE Linux Enterprise

This section describes how to install and configure the dashboard on the controller node.

The only core service required by the dashboard is the Identity service. You can use the dashboard in combination with other services, such as Image service, Compute, and Networking. You can also use the dashboard in environments with stand-alone services such as Object Storage.

Note

This section assumes proper installation, configuration, and operation of the Identity service using the Apache HTTP server and Memcached service.

Install and configure components

1. Install the packages:

   # zypper install openstack-dashboard

2. Configure the web server:

   # cp /etc/apache2/conf.d/openstack-dashboard.conf.sample \
     /etc/apache2/conf.d/openstack-dashboard.conf
   # a2enmod rewrite

3. Edit the /srv/www/openstack-dashboard/openstack_dashboard/local/local_settings.py file and complete the following actions:

   • Configure the dashboard to use OpenStack services on the controller node:

     OPENSTACK_HOST = "controller"

   • Allow your hosts to access the dashboard:

     ALLOWED_HOSTS = ['one.example.com', 'two.example.com']

     Note

     ALLOWED_HOSTS can also be ['*'] to accept all hosts. This may be useful for development work, but is potentially insecure and should not be used in production. See Django documentation for further information.

   • Configure the memcached session storage service:

     SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
     
     CACHES = {
         'default': {
              'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
              'LOCATION': 'controller:11211',
         }
     }

     Note

     Comment out any other session storage configuration.

   • Enable the Identity API version 3:

     OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

   • Enable support for domains:

     OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

   • Configure API versions:

     OPENSTACK_API_VERSIONS = {
         "identity": 3,
         "image": 2,
         "volume": 2,
     }

   • Configure Default as the default domain for users that you create via the dashboard:

     OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

   • Configure user as the default role for users that you create via the dashboard:

     OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

   • If you chose networking option 1, disable support for layer-3 networking services:

     OPENSTACK_NEUTRON_NETWORK = {
         ...
         'enable_router': False,
         'enable_quotas': False,
         'enable_distributed_router': False,
         'enable_ha_router': False,
         'enable_lb': False,
         'enable_firewall': False,
         'enable_vpn': False,
         'enable_fip_topology_check': False,
     }

   • Optionally, configure the time zone:

     TIME_ZONE = "TIME_ZONE"

     Replace TIME_ZONE with an appropriate time zone identifier. For more information, see the list of time zones.

Finalize installation

• Restart the web server and session storage service:

  # systemctl restart apache2.service memcached.service

  Note

  The systemctl restart command starts each service if not currently running.
