Dengan VirtualEnv

Lihat [3]

sudo pip install virtualenvwrapper
sudo nano ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
source ~/.bash_profile
mkvirtualenv -p /opt/python279/bin/python scanadmin --no-site-packages
cd apps/scanadmin/ODKScan_webapp
workon scanadmin

pip install -r requirements.pip

Untuk uji coba, jalankan perintah ini di direktori scanadmin :

python manage.py runserver 8080

Jika muncul error seperti dibawah, 

Request Method:	GET
Request URL:	http://scanadmin.np:8080/admin/ODKScan_webapp/formimage/
Django Version:	1.5.1
Exception Type:	TemplateDoesNotExist
Exception Value:	admin/login.html
Exception Location:	/home/wildan/.virtualenvs/scanadmin/lib/python2.7/site-packages/django/template/loader.py in find_template, line 139
Python Executable:	/home/wildan/.virtualenvs/scanadmin/bin/python
Python Version:	2.7.9

Install ulang semua requirements dengan perintah :

pip install -r requirements.pip --ignore-installed --force-reinstall --upgrade --no-cache-dir

lalu coba lagi :

python manage.py runserver 8080

Apache + mod_wsgi

Berikut adalah konfigurasi virtualhost yang digunakan :

ODKScanCore 

Untuk kompilasi ODKScanCore dapat membaca [8]

Mac OS X

Nginx + Django + virtualenv 

cd scanadmin
pip install virtualenv
virtualenv venv
source venv/bin/activate 

sudo pip install -r requirements.txt

Ketika menjalankan perinta ini error :

pip install -r ../../requirements.txt --global-option=build_ext --global-option="-I/usr/local/Cellar/mysql-connector-c/6.1.11/include" --global-option="-L/usr/local/opt/openssl/lib"
mkdir /usr/local/etc/uwsgi/vassals
ln -s /path/to/scanadmin/scanadmin_uwsgi.ini /usr/local/etc/uwsgi/vassals/
supervisorctl -c supervisord.conf reload
sudo supervisorctl
