[Solved] Gateway Timeout error: Cannot access Horizon on OpenStack Newton.
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
