ImportError: No module named mysite.wsgi - uwsgi and nginx settings

Question

I am having trouble setting up my production server. Till now, I was using openshift.com for my apps. But now I created an app with large db and 1GB was quickly not enough. So I am moving my app called ebook to my vps server. I tried to follow this docs with sock option and emperor mode.
I installed virtualenv, uwsgi and nginx. If I run my app with ./manage.py runserver ip:port , I can view my website on ip:port.
Because of openshift I have a little weird paths:
virtualenv path /var/www/django/ebook
openshift project path /var/www/django/ebook/ebook
project path /var/www/django/ebook/ebook/wsgi/ebook where I have manage.py and controller (app with settings.py file in it)

However running it with uwsgi does not work. Import error occured:
ImportError: No module named controller.wsgi
Full uwsgi output:

this is my ebook_uwsgi.ini that I run uwsgi with:

    # ebook_uwsgi.ini file
    [uwsgi]

    # Django-related settings
    # the base directory (full path)
    chdir           = /var/www/django/ebook/ebook/
    # Django's wsgi file
    module          = controller.wsgi:application
    # the virtualenv (full path)
    home            = /var/www/django/ebook

    # process-related settings
    # master
    master          = true
    # maximum number of worker processes
    processes       = 10
    # the socket (use the full path to be safe
    socket          = /tmp/ebook.sock
    # ... with appropriate permissions - may be needed
    chmod-socket    = 664
    uid             = www-data
    gid             = www-data
    # clear environment on exit
    vacuum          = true
    no-site         = True
    wsgi-file       = /var/www/django/ebook/ebook/wsgi/ebook/controller/wsgi.py
    env             = DJANGO_SETTINGS_MODULE=controller.settings # set an environment variable

and ebook_nginx.conf: # mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    server unix:///tmp/ebook.sock; # for a file socket
    #server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      8001;
    # the domain name it will serve for
    server_name MY_IP_ADDRESS #.bookdownloading.com; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    location /media  {
        alias /var/www/django/ebook/ebook/data;  # your Django project's media files - amend as required
    }

    location /static {
        alias /var/www/django/ebook/ebook/wsgi/static/; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  unix:///tmp/ebook.sock;
        include     /var/www/django/ebook/ebook/uwsgi_params; # the uwsgi_params file you installed
    }
}

And this is my wsgi.py file in controller app:

import sys
activate_this = '/var/www/django/ebook/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))


import os
if hasattr(sys, 'real_prefix'):
    print "virtualenv is active"

sys.path.append("/var/www/django/ebook/lib/python2.7/site-packages/")
sys.path.append("/var/www/django/ebook/ebook/wsgi")
sys.path.insert(0, "/var/www/django/ebook/ebook/wsgi/ebook")
sys.path.append("/var/www/django/ebook/ebook/wsgi/ebook/controller")

# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
# os.environ["DJANGO_SETTINGS_MODULE"] = "digrin.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "controller.settings")

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

I have so many append/insert commands to sys.path because I was not sure which one is enough. I guess insert one should be enough.
I am running apache for php, that is why I use port 8001. App gives me ImportError. Any idea, what am I missing?

Openshift structure confused me a little. chdir should have been:
chdir = /var/www/django/ebook/ebook/wsgi/ebook/
