I'm working under CentOS 6.4 + Openstack - Havana, everything works fine except Horizon.

I get error in /var/log/httpd/error_log:

chen, could you please provide your settings.py as well?

[li,chen (chen-li)]

what is settings.py ?

[li,chen (chen-li)]

where can I find settings.py ?

[Matthias Runge (mrunge)]

did you change anything on your package? please give the corresponding version
rpm -q openstack-dashboard

you can find settings.py under /usr/share/openstack-dashboard/openstack_dashboard/

how did you manage to produce your issue?

[Matthias Runge (mrunge)]

if you don't know, where to locate settings.py, it's unlikely, you changed it. in that case it's not necessary to provide it.

[li,chen (chen-li)]

rpm -q openstack-dashboard
openstack-dashboard-2013.2-3.el6.noarch

[li,chen (chen-li)]

>> "how did you manage to produce your issue?" ?

1. start httpd
2. use firefox to connect dashboard
3. use admin user to login => issue appears

[Matthias Runge (mrunge)]

Chen, could you please use the distributed config file? Apparently you made changes, e.g. you set CACHES twice and changed keystone API as well.

[li,chen (chen-li)]

What should I do to use "distributed config file" ??
Sorry , I'm really new here......

Thanks.
-chen

[li,chen (chen-li)]

I have the "CACHE_BACKEND" setting after I installed dashboard, but I didn't find anything about this from internet, all settings are
"CACHES ", so I just add "CACHES" at the end.

About keystone,I don't have any V3 API endpoint exist, but I noticed there is some request to keystone with V3 in the URL, so I googled for it, and set it to use v2.

[li,chen (chen-li)]

I download horizon code from github(https://github.com/openstack/horizon.git).
And, did cp /home/git/horizon/openstack_dashboard/local/local_settings.py.example /etc/openstack-dashboard/local_settings.

But, after I restart httpd, i get error:

[Matthias Runge (mrunge)]

to comment #11:

that's clear, because the lock file can not be created under /usr/share....

Were you able to find the reason for your issue?

CACHE and CACHES settings are the same
CACHE is old syntax, CACHES for the newer one.

[li,chen (chen-li)]

The issue is gone, after I run:

1. cd /usr/share/openstack-dashboard
2. chown -R apache:apache *

And also, the previous issue have gone too.
I think this is because I'm using the distributed config file as you suggested.

I add the v2 configuration back to the local_settings:
     OPENSTACK_API_VERSIONS = {
          "identity": 2.0
     }

Still, everything works fine.

So, I set this bug to Invalid because I think the issue is caused by the CACHE configurations.
It is an configuration issue not a bug.

But, there is no "SESSION_ENGINE" parameter exist in local_settings.py.example.
I'm still really confused about "http://docs.openstack.org/trunk/openstack-compute/install/yum/content/dashboard-sessions.html"

Thanks.
