关于wsgi.py中的wsgi模块的Ubuntu 16.04服务器错误

Question

我要在虚拟主机的ubuntu服务器上设置一个django应用程序。
我配置了我的虚拟主机，以便出现一些东西！
但它仍然存在上给我，因为有些问题500内部错误，你在这里看到：

我真的很感谢您的答复

更新＃2

如果我使用此代码在我的wsgi.py：

import os 

from django.core.wsgi import get_wsgi_application 

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings' 
application = get_wsgi_application() 

堆栈跟踪将成为此:(mmemp是我的应用程序的名称）：

mod_wsgi (pid=5579): Target WSGI script '/var/www/mmcba/mmemp/wsgi.py' cannot be loaded as Python module. 
mod_wsgi (pid=5579): Exception occurred processing WSGI script '/var/www/mmcba/mmemp/wsgi.py'. 
Traceback (most recent call last): 
    File "/var/www/mmcba/mmemp/wsgi.py", line 16, in <module> 
    application = get_wsgi_application() 
    File "/usr/local/lib/python2.7/dist-packages/django/core/wsgi.py", line 13, in get_wsgi_application 
    django.setup(set_prefix=False) 
    File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 22, in setup 
    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) 
    File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 56, in __getattr__ 
    self._setup(name) 
    File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 41, in _setup 
    self._wrapped = Settings(settings_module) 
    File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 110, in __init__ 
    mod = importlib.import_module(self.SETTINGS_MODULE) 
    File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module 
    __import__(name) 
ImportError: No module named mmemp.settings 

我的虚拟主机配置，这就是：

Listen 80 

NameVirtualHost 148.251.218.202:80 

<VirtualHost *:80> 
     ServerAdmin webmaster@mmcba.com 
     ServerName mmcba.com 
     ServerAlias www.mmcba.com 

     WSGIScriptAlias//var/www/mmcba/mmemp/wsgi.py 

     <Directory /var/www/mmcba/mmemp> 
     <Files wsgi.py> 
     Require all granted 
     </Files> 
     </Directory> 

     ErrorLog ${APACHE_LOG_DIR}/error.log 
     CustomLog ${APACHE_LOG_DIR}/access.log combined 

</VirtualHost> 

Answer 1

解决方案：
将项目和应用程序目录添加到wsgi.py中的sys.path，它会工作。
它

import sys 
sys.path.append('<Project_Directory>') 
sys.path.append('<Project_Directory>/AppName') 

Answer 2

如果你使用Django 1.7+做这个替换您的wsgi.py的内容：

import os 

from django.core.wsgi import get_wsgi_application 

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings' 
application = get_wsgi_application() 

或尝试添加以下行settings.py

import django 
django.setup()
