I've successfully deployed OpenStack Havana using Juju over Ubuntu precise. Each charm on dedicated server and everything looks normal.
When I tried to access horizon, I get the login page and successfully authenticate, then I get 500 Internal Server Error.
I checked /var/log/apache2/error.log and found the first portion of this: http://pastebin.ubuntu.com/6957430/
After some googling I followed the instructions on this thread (https://bugs.launchpad.net/ubuntu/+source/libapache2-mod-python/+bug/1073147), yet I still couldn't access horizon and found the second portion on the pastebin log file.
Then lastly I tried
sudo a2dismod deflate to change the logging mode, so I found the third portion on the log file.
Now the status of horizon charm is 1 hook failed "config-changed" and I still cannot access it.
This is my
juju status output: http://pastebin.ubuntu.com/6957440/
Please help, Thank you
