Gunicorn settings for virtualenvwrapper

Question

I am trying to deploy a test site which made using Django and virtualenvwrapper. I want to use nginx for requests.I used Taskbuster's tutorial. So my project layer is similar as below :

--abctasarim                       **main folder
--manage.py                        **django manage file
----/yogavidya                     ** project folder
----/yogavidya/wsgi.py             **wsgi file
----/yogavidya/settings/base.py    ***settings

I prepared a script to use with gunicorn. I addressed virtualenv to virtualenvwrapper envs

#!/bin/bash

NAME="yogavidya"                              #Name of the application (*)
DJANGODIR=/home/ytsejam/public_html/abctasarim     # Django project directory (*)
SOCKFILE=/home/ytsejam/public_html/abctasarim/run/gunicorn.sock        # we will communicate using this unix socket (*)
USER=ytsejam                                        # the user to run as (*)
GROUP=webdata                                     # the group to run as (*)
NUM_WORKERS=1                                     # how many worker processes should Gunicorn spawn (*)
DJANGO_SETTINGS_MODULE=yogavidya.settings.base           # which settings file should Django use (*)
DJANGO_WSGI_MODULE=yogavidya.wsgi                     # WSGI module name (*)

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $DJANGODIR
source /home/ytsejam/.virtualenvs/yv_dev/bin/activate
#export /home/ytsejam/.virtualenvs/yv_dev/bin/postactivate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec /home/ytsejam/public_html/abctasarim/gunicorn  \
  --name $NAME \
  --workers $NUM_WORKERS \
  --env DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE \
  --pythonpath $DJANGODIR \
  --user $USER \
  --bind=unix:$SOCKFILE yogavidya.wsgi:application

When I try to run it , I am getting an error for my service file :

...
ImportError: No module named ' '
...

How can I fix my script to serve the site correctly ?

Thanks

virtualenvwrapper is supposed to be what you use in development. You want to deploy using the package that virtualenvwrapper is built on—the virtualenv package. The best suggestion I have for you for how to make this work would be to try the steps that you would normally use to start your virtualenvwrapper environment, namely sourcing the shell script and then using workon:

NAME="yogavidya"                              #Name of the application (*)
DJANGODIR=/home/ytsejam/public_html/abctasarim     # Django project directory (*)
SOCKFILE=/home/ytsejam/public_html/abctasarim/run/gunicorn.sock        # we will communicate using this unix socket (*)
USER=ytsejam                                        # the user to run as (*)
GROUP=webdata                                     # the group to run as (*)
NUM_WORKERS=1                                     # how many worker processes should Gunicorn spawn (*)
DJANGO_SETTINGS_MODULE=yogavidya.settings.base           # which settings file should Django use (*)
DJANGO_WSGI_MODULE=yogavidya.wsgi                     # WSGI module name (*)

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $DJANGO_DIR
source /path/to/virtualenvwrapper.sh
workon yv_dev

You should also just try invoking gunicorn from the command line after activating your virtualenv.

Here’s how you can do it with virtualenv:

cd /home/ytsejam/public_html/abctasarim 
sudo pip install virtualenv
virtualenv .
. bin/activate
pip install -r requirements.txt
pip install gunicorn

gunicorn script:

NAME="yogavidya"                              #Name of the application (*)
DJANGODIR=/home/ytsejam/public_html/abctasarim     # Django project directory (*)
SOCKFILE=/home/ytsejam/public_html/abctasarim/run/gunicorn.sock        # we will communicate using this unix socket (*)
USER=ytsejam                                        # the user to run as (*)
GROUP=webdata                                     # the group to run as (*)
NUM_WORKERS=1                                     # how many worker processes should Gunicorn spawn (*)

cd $DJANGO_DIR
. bin/activate

# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

exec /home/ytsejam/public_html/abctasarim/bin/gunicorn  \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user $USER \
  --bind=unix:$SOCKFILE yogavidya.wsgi:application
