System requirements

Before you install theOpenStack dashboard, you must meet the following system require­ments:

•OpenStack Compute installation.Enable the Identity Service for user and project man­agement.

Note the URLs of the IdentityService and Compute endpoints.

• Identity Service user withsudo privileges. Because Apache does not serve content from a root user, usersmust run the dashboard as an Identity Service user with sudo privileges.^[1]

---

Python 2.6 or 2.7. The Pythonversion must support Django. The Python version should run on any system,including Mac OS X. Installation prerequisites
might differ by plat­form.

Then, install and configurethe dashboard on a node that can contact the Identity Service.

Provideusers with the following information so that they can access the dashboardthrough a web browser on their local machine:

•  The public IP address fromwhich they can access the dashboard

•  The user name and password withwhich they can access the dashboard

Your web browser, and that of your users, must support HTML5 andhave cookies and JavaScript enabled.

Install the packages:

# yum install openstack-dashboard httpd mod_wsgi memcached python-memcached

To configure the dashboard

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

a.         Configure the dashboard to use OpenStack services on the controller node:

OPENSTACK_HOST = " controller'

b.        Allow all hosts to access the dashboard:

ALLOWED_HOSTS =  ['*']

c.         Configure the memcached session storage service:

CACHES = {

'default': {

'BACKEND': 'django.core.cache.backends.memcached.

MemcachedCache',

'LOCATION': '127.0.0.1:11211',

}

}

To finalize installation

1.       On RHEL and CentOS, configureSELinux to permit the web server to connect to Open- Stack services:

#   setsebool -P httpd_can_network_connect on

2.       Due to a packaging bug, thedashboard CSS fails to load properly. Run the following command to resolve thisissue:

#   chown -R apache：apache /usr/share/openstack-dashboard/static

For more information, see thebug report.

3.       Start the web server andsession storage service and configure them to start when the system boots:

#   systemctl enable httpd.service memcached.service

#   systemctl start httpd.service memcached.service
