OpenStack: Installing Horizon Dashboard

[root@server2-a ~(keystone_admin)]$ yum -y install -y mod_wsgi httpd mod_ssl openstack-dashboard memcached python-memcached

In /etc/openstack-dashboard/local_settings update ALLOWED_HOSTS; modify the OPENSTACK_HOST lines as follows:

ALLOWED_HOSTS = ['*']
OPENSTACK_HOST = "172.25.2.10"

Update CACHES section by uncommenting the first block and commenting second block. The LOCATION setting points to the Memcached service, either locally or a remote IP address:

CACHES = {
   'default': {
       'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
       'LOCATION' : '127.0.0.1:11211',
   }
}

#CACHES = {
#    'default': {
#        'BACKEND' : 'django.core.cache.backends.locmem.LocMemCache'
#    }
#}

• Ensure the _member_ role exists:
