problem with openstack dashboard installation in multinode deployment

Hi Paul

Can you try http://<your-address-or-name>/horizon ?

this bug can be related with your question - https://bugs.launchpad.net/ubuntu/+source/horizon/+bug/1020313
in my /etc/apache2/conf.d/openstack-dashboard.conf I have WSGIScriptAlias /horizon /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi

and http://x.x.x.x/horizon - works for me

Anton- Thanks for your quick response. I tried appending /horizon (and horizon/auth/login) - while it didnt work I did get a different message - internal server error. I verified that my settings in apache2/conf.d do match yours. My problem must be somewhere else. I have attached my local_settings.py for reference. Keystone, horizon, mysql, nova-api, nova-scheduler, rabbitmq all run on my cloud controller node (x.x.x.71 below); nova-compute, quantum and l2/dhcp/l3 agents run on seperate nodes. I used the IP of cloud controller node (.71) in defining all endpoints - not sure if that is correct.

This problem has been resolved. When launched Horizon going to var/www/dashboard, and should be going to to /usr/share/openstack-dashboard/openstack_dashboard/wsgi, created symlink and started working.
