肯定需要关于 *** 的第一篇文章 + 帮助：

我正在尝试设置一个 Ubuntu 16.04 服务器来托管我的 Django 应用程序，但是我遇到了一个奇怪的 uWSGI 错误；每当我跑步时：

uwsgi --socket test.sock --module api.wsgi:app --chmod-socket=66

我明白了：

Python version: 3.5.2 (default, Nov 23 2017, 16:37:01)  [GCC 5.4.0 20160609]

During handling of the above exception, another exception occurred:

这是我的 wsgi.py 文件：

import os

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'settings')
os.environ.setdefault('DJANGO_CONFIGURATION', 'Production')

from configurations.wsgi import get_wsgi_application

application = get_wsgi_application()

这是我的 uwsgi.ini 文件：

[uwsgi]

project = mysite
base = /home/ubuntu

chdir = %(base)/%(project)
home = %(base)/%(project)/env
module = %(project).wsgi:application

vacuum = true


# process-related settings
master = true
processes = 8
socket = /run/uwsgi/mysite.sock
chmod-socket = 666
max-requests = 50000

logto = /var/log/uwsgi/app/logs.log

为了更好的衡量，这是我的 nginx 文件：

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django 
    server unix:///home/ubuntu/mysite/test.sock; # for a file socket
    #server 127.0.0.1:8001; # for a web port socket (we'll use this first)


# configuration of the server
server 
    # the port your site will be served on
    listen      8000;
    # the domain name it will serve for
    server_name mysite.io; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    location /media  
        alias /home/ubuntu/mysite/static;  # your Django project's media files - amend as required
    

    location /static 
        alias /home/ubuntu/mysite/media; # your Django project's static files - amend as required
    

    # Finally, send all non-media requests to the Django server.
    location / 
        uwsgi_pass  django;
        include     uwsgi_params; # the uwsgi_params file you installed
    

我真的不知道是什么原因造成的。我现在尝试使用 Gunicorn，它显示了同样的错误。非常感谢任何帮助！ :)

【参考方案1】：

在 uwsgi.py 你有：

application = get_wsgi_application()

你正在运行带有参数的uwsgi：

uwsgi --socket test.sock --module api.wsgi:app --chmod-socket=66

尝试用api.wsgi:application 替换api.wsgi:app，看看它是否运行。
