Install Openstack Horizon Dashboard - Openstack Tutorial

What is Openstack Horizon?

The OpenStack Dashboard, also known as horizon is a web interface that enables cloud administrators and users to manage various OpenStack resources and services.

The Dashboard enables web-based interactions with the OpenStack Compute cloud controller through the OpenStack APIs. Horizon enables you to customize the brand of the dashboard and it provides a set of core classes and reusable templates and tools.

Lab Setup for this Openstack Deployment:
Server Names : node1 and node2.
OS :  CentOS 7.2 - 64 Bit
Enabled Internet connection.


  1. Installed Centos 7.1 – 64 Bit

  2. Make sure each hosts are reachable. I made an entries in hosts file only.     controller-node1.learnitguide.net  controller-node1     compute-node1.learnitguide.net  compute-node1

  3. Verify the internet connection, because we use public repo's to install these components.

  4. Take a backup or snapshot at different stages to restore in case of failure.

  5. Disable Selinux and Stop firewall to avoid issues during the installations (systemctl stop firewalld ; systemctl disable firewalld) or allow each component services on firewall after installations.

  6. Enabled Openstack Liberty Repositories.

  7. Installed Openstack Liberty Packages.

  8. Installed and Configured MariaDB(MySQL) Database.


Install Openstack Horizon Dashboard and Configure it on Node1 (controller node).

Lets Install the required packages for Openstack Horizon component.

[root@node1 ~]# yum install openstack-dashboard

Configure Openstack Horizon components.

Edit the /etc/openstack-dashboard/local_settings file and make the below changes to use OpenStack services on the controller node:


Replace 'node1' with your controller node name.

Allow all hosts to access the dashboard:


Configure the memcached session storage service:

'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': 'node1:11211',

Replace 'node1' with your controller node name and comment out any other session storage configuration.

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


Enable the multi-domain model:


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

"identity": 3,
"volume": 2,
'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:


Replace TIME_ZONE with an appropriate time zone identifier.

Enable the web server and session storage service to start when the system boots.

[root@node1 ~]# systemctl enable httpd.service
[root@node1 ~]# systemctl enable memcached.service

Restart the web server and session storage service.

[root@node1 ~]# systemctl restart httpd.service
[root@node1 ~]# systemctl restart memcached.service

Access your Openstack Dashboard now.

Open your browser and access the dashboard URL Enter your username and passwd and start using the openstack environment. You can watch this demo on youtube video "How to Install Openstack Horizon Dashboard".
