Horizon uses OpenStack API’s to interact with the cloud controller, you can also customize the dashboard for branding. Here we will be using apache servers as web server to serve horizon dashboard.

System requirements:

Before proceeding ahead, make sure your system meets below requirements.

OpenStack compute installation, it enables identity service for user and project management.

Dashboard should be run as identity service user with sudo privileges.

Python version should support Django, v 2.7.

Install and configure dashboard on a node that can contact the identity service.

Install the Horizon components:

Install the following OpenStack dashboard package on the controller node.

# apt-get install openstack-dashboard

Configure the Horizon:

Edit the /etc/openstack-dashboard/local_settings.py file.

# nano /etc/openstack-dashboard/local_settings.py

Modify below settings.

## Enter controller node details.

OPENSTACK_HOST = "controller"

## Allow hosts to access dashboard

ALLOWED_HOSTS = '*'

## Comment out any other storage configuration.

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

## Default role that will assigned when the user is created via dashboard.

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

## Replace TIME_ZONE with your Time zone.

TIME_ZONE = "TIME_ZONE"

Restart the apache service.

# service apache2 restart

Access the dashboard using the following url

http://controller/horizon or http://ip-add-ress/horizon

Enter the admin credential that we created during Keystone configurations.
