what could be wrong?
complete noob here.

If you are deploying django project for production under ubuntu server it is recommended to use WSGI. Just fallow the django documentation: https://docs.djangoproject.com/en/1.3/howto/deployment/modwsgi/
Installing apache with wsgi under ubuntu is easy:
apt-get install libapache2-mod-wsgi
In case you just want to explore django you do not need to setup apache or anything. Just use manage.py runserver instead.

deploy django on tomcat

I am using Django 1.8 on Jython in Windows 10. Have created a simple Django project following the tutorial https://docs.djangoproject.com/en/1.8/intro/tutorial01. After packaging using buildwar(including jars), when I deploy the mysite.war archive in tomcat, I get an error.
My project name is mysite, I have referenced the Jython path in web.xml.
My project structure is
-mysite
-WEB-INF
-lib

-jython.jar
-lib-python

-doj
-polls
-application_settingspy.class
-application_settings.py
-eggs.pth
-web.xml
-wsgi
Error is

Horizon fails to start

I've followed this guide: https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/Identity_Management_-KeyRock-_Installation_and_Administration_Guide
When i run the server i get:

I've tried using --pythonpath but to no avail. I've also ran ./run_tests.sh and here are the results: http://pastebin.com/6i7Ws5Ej.
System:
CentOS 6.5 x64,
python 2.6.6
Any idea how to solve this? any info i might have forgotten don’t hesitate to ask
Edit:
I've switched to ubuntu 12 to follow the tutorial step by step. I got keystone running but horizon still fails and gives me the same error.
A fix was also committed on KeyRock's Github account.
Here is the issue.
Manually updating pbr to 1.3.0 directly from python and pip solved all issues

DJANGO_PATH errors and settings issues

I recently upgraded my Ubuntu to 14.04, and consulted this question to solve my erros, ImportError: No module named _io in ubuntu 14.04. That was solved perfectly.
I also checked out this question as it's similar to mine, Consistently getting ImportError: Could not import settings 'myapp.settings' error, but could not use the same solution.
I do not use manage.py in my project and I have done numerous exports of the PYTHON_PATH to no end of my issues. Here is my traceback;

I found the problem:
The was an issue with the egg files during the virtualenv reinstall. Though the programs were there, they couldn't be found. I just performed another install of the requirements to refresh the egg info.

mod_wsgi + python 2.7.5 import error

I have installed and probably right configurated apache2, mod_wsgi and python 2.7.5. The problem is that 127.0.0.1 is not opening (loading is just freezed) and I see following log in error.log:

Tried to restart apache, but it's not working. Thanks for any help!
Just found solution. I checked 'sys.prefix' in my python's interpretator and it printed '/usr/local', but I had not set WSGIPythonHome in apache config (as written in mod_wsgi docs for this case). And just for experiment I set 'WSGIPythonHome /usr'. It's strange, but it resolves my problem, everything is fine now!

django - apache integration

Im tired of trying to put this working :(
So, here is my problem:
Added to httpd.conf :
Location "/ps3t/">
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE ps3t.settings
PythonOption django.root /ps3t
PythonDebug On
PythonPath "['/home/fabriciols'] + sys.path"
/Location>
removed the "<" from localtion, but on my httd.conf have

my project structure :
/home/fabriciols/ - root dir
./ps3t - project
./ps3t/myps3t - app
every user has read perm in all files ...
what im doing wrong ? :/
find the solution, but i thing this isnt the best solution
chmod +rx -R /home/fabriciols/
i read that apache only need READ perm on dir, but it seems to need execute perm too :D
