Install and configure¶

Install and configure components¶

1. Install the packages:

   # yum install openstack-dashboard
   

2. Edit the /etc/openstack-dashboard/local_settings file and complete the following actions:

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

     OPENSTACK_HOST = "controller"
     

   • Allow all hosts to access the dashboard:

     ALLOWED_HOSTS = ['*', ]
     

   • Configure the memcached session storage service:

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

     Note

     Comment out any other session storage configuration.

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

     OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
     

   • Enable the multi-domain model:

     OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
     

   • Configure the service API version so that you can log into the dashboard by the Keystone V3 API:

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

   • 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¶

• Start the web server and session storage service and configure them to start when the system boots:

  # systemctl enable httpd.service memcached.service
  # systemctl restart httpd.service memcached.service
  

  Note

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