nginx+uwsgi部署Django遇到了麻烦

Question

首先说明：电脑环境为Ubuntu 16.10,我使用conda管理开发环境 !!!

uwsgi使用conda install的pip安装

uwsgi ini文件

# 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
        }
    }

当启动 sudo uwsgi --ini backend_uwsgi.ini 后，结果却是

nginx界面是

我看到 其中 !!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!
no request plugin is loaded, you will not be able to manage requests.
you may need to install the package for your language of choice, or simply load it with --plugin.

于是加上 --plugin python3,得到结果却是

Traceback (most recent call last):
File "./backend/wsgi.py", line 12, in <module>

from django.core.wsgi import get_wsgi_application

ImportError: No module named 'django'
unable to load app 0 (mountpoint='') (callable not found or import error)

nginx界面变成

nginx刷新，uswgi那里有反应。

怎么办？求助大神解救。。。

Answer 1

sudo uwsgi

你切换了环境。你的 Django 不是安装在系统全局的。

如果你使用了 virtualenv 的话，你可以在 uwsgi 的配置中指定 virtualenv 的位置。
