nginx+uwsgi a rencontré des problèmes lors du déploiement de Django

Question

Tout d'abord, l'environnement informatique est Ubuntu 16.10, j'utilise conda pour gérer l'environnement de développement !!!

uwsgi est installé à l'aide de pip

de conda install

fichier ini uwsgi

# backend_uwsgi.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir           = /home/yangtz/developproject/backend

# Django's wsgi file
# wsgi-file = /home/yangtz/developproject/backend/backend/wsgi.py
module          = backend.wsgi

 
# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10
# the socket (use the full path to be safe
socket          = /home/yangtz/developproject/backend/backend/backend.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true

# daemonize = /home/yangtz/developproject/backend/uwsgi.log

backend_nginx.conf

    # the upstream component nginx needs to connect to
    upstream django {
        server unix:/home/yangtz/developproject/backend/backend/backend.sock; # for a file socket
        # server 127.0.0.1:8000; # for a web port socket (we'll use this first)
    }
    # configuration of the server
    server {
        # the port your site will be served on
        listen      80;
        # the domain name it will serve for
        server_name 127.0.0.1; # substitute your machine's IP address or FQDN
        charset     utf-8;
    
        access_log      /home/yangtz/developproject/nginx_access.log;
        error_log       /home/yangtz/developproject/nginx_error.log;
    
        # max upload size
        client_max_body_size 75M;   # adjust to taste
    
        # Django media
        # location /media  {
        #     alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
        # }
    
        location /static {
            alias /home/yangtz/developproject/backend/static; # your Django project's static files - amend as required
        }
    
        # Finally, send all non-media requests to the Django server.
        location / {
            uwsgi_pass  django;
            include     /etc/nginx/uwsgi_params; # the uwsgi_params file you installed
        }
    }

Après avoir démarré sudo uwsgi --ini backend_uwsgi.ini, le résultat est

l'interface nginx est

Je l'ai vu !!!!!!!!!!!!! ATTENTION!!!!!!!!!!!!
aucun plugin de requête n'est chargé, vous ne pourrez pas gérer les requêtes
. vous devrez peut-être installer le package pour la langue de votre choix, ou simplement le charger avec --plugin.

J'ai donc ajouté --plugin python3, et le résultat était

Traceback (dernier appel le plus récent) :
Fichier "./backend/wsgi.py", ligne 12, dans <module>

from django.core.wsgi import get_wsgi_application

ImportError : Aucun module nommé 'django'
impossible de charger l'application 0 (mountpoint='') (appelable introuvable ou erreur d'importation)
aucune application chargée en mode dynamique complet

l'interface nginx devient

nginx se rafraîchit, répond uswgi.

Que faire ? Demandez à Dieu de l'aide. . .

Answer 1

sudo uwsgi

Vous avez changé d'environnement. Votre Django n'est pas installé globalement sur le système.

Si vous utilisez virtualenv, vous pouvez spécifier l'emplacement de virtualenv dans la configuration uwsgi.
