Hi. I'm trying to install OpenStack Newton using the documentations here: http://docs.openstack.org/newton/install-guide-ubuntu/ (http://docs.openstack.org/newton/inst...)

I successfully installed these services: Identity, Image, Compute, and Network. Now I try to install Dashboard and I do it EXACTLY the same as the instructions at: http://docs.openstack.org/newton/install-guide-ubuntu/horizon-install.html (http://docs.openstack.org/newton/inst...)

However, I cannot open the Horizon (http://controller/horizon). It does not give any errors at first, it's just stuck in loading and after a while, I receive Gateway Timeout error.

Please see /etc/openstack-dashboard/local_settings.py in here: http://paste.openstack.org/show/592974/

Thank you.

Probably Apache can't reach the WSGI components that make up Horizon. Check /var/log/apache2, and check if any Horizon wsgi processes are running.

Thank you very much. I will post the logs here. But if it is the cause of error, how can I fix it?

If the processes are not running, find out why. If they are, find out what prevents Apache from reaching them. The log files may contain clues.

It seems wsgi works fine. There is just one error: [Thu Dec 22 01:36:03.125705 2016] [wsgi:error] [pid 14317:tid 140137276241664] [client 10.0.0.10:57518] Truncated or oversized response headers received from daemon process 'horizon': /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.ws

I solved the problem as below.

1) open the dashboard configuration file:

#gedit /etc/apache2/conf-available/openstack-dashboard.conf

2) Add the following line to the configturation:

WSGIApplicationGroup %{GLOBAL}

3) Reload the Apache

#service apache2 reload

BOOM! enjoy the horizon.

It helped me as well on one of the setups which I recently did. But what I am surprised of that Dashboard of my another setup is working smoothly without it. Both the setups are of Newton Version.

If the problem still persists after default setting delete the duplicate cells which are mapped by using nova-manage

Sure. I have two VMs on VMware workstation on Windows 10. The first VM is controller with 8 CPU cores and 6 GB of RAM, and the second one is the compute node with 2 GB of RAM and 2 CPU cores.

@AmirV Try with this OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST in /etc/openstack-dashboard/local_settings.py .For me this works fine.
