将Django应用程序部署到Digital Ocean-Gunicorn错误

Question

I'm trying to deploy my first app to digital ocean with help of this tutorial .

When I try to run sudo supervisorctl restart [appname], I get the following error. (This is only a part of the error)

     [2019-01-16 09:10:49 +0000] [2653] [ERROR] Exception in worker process

    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named 'authSection'

My setup in the server is

and the supervisor config file

#!/bin/sh
[program:productUploader]
command=/home/srimal/django_project/bin/gunicorn_start
user=srimal
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/home/srimal/logs/gunicorn-error.log

and the gunicorn_start file

#!/bin/bash

NAME="productUploader"
DIR=/home/srimal/django_project
USER=srimal
GROUP=srimal
WORKERS=3
BIND=unix:/home/srimal/run/gunicorn.sock
DJANGO_SETTINGS_MODULE=productUploader.shadesProductUploader.settings
DJANGO_WSGI_MODULE=productUploader.shadesProductUploader.wsgi
LOG_LEVEL=error

cd $DIR
source /home/srimal/django_project/bin/activate

export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DIR:$PYTHONPATH

exec /home/srimal/django_project/bin/gunicorn    ${DJANGO_WSGI_MODULE}:application \
 --name $NAME \
 --workers $WORKERS \
 --user=$USER \
 --group=$GROUP \
 --bind=$BIND \
 --log-level=$LOG_LEVEL \
 --log-file=-

What am I doing wrong?

Answer 1

It seems as though the productUploader directory is a python package, based on the fact that you're passing it in the dotted path to DJANGO_SETTINGS_MODULE and DJANGO_WSGI_MODULE . Thus you should also do the same for the apps in INSTALLED_APPS :

INSTALLED_APPS = [
    'productUploader.authSection',  # Use full path
    'productUploader.mainSection',  # Use full path
    'django.contrib.humanize',
    'django.contrib.admin', 
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles',
]
