Question

我有一个使用WSGI和Apache2在生产中提供的站点。那部分工作正常。

但是，在对网站采用12-Factor配置标准（使用django-environ）进行一些更改之后，我从Apache中找到了settings.py的错误。错误日志。

即，

[Tue Aug 15 20:46:08.764757 2017] [wsgi:error] [pid 5245:tid 139820676769536] Traceback (most recent call last):

在本地环境中，这些文件运行良好。但是，我怀疑在本地环境中wsgi.py文件并未真正使用，因此不会抛出此错误。

现在，我确保在virtualenv中安装了django-environ模块。我用pip list验证了它。

来自settings.py的相关代码：

import os

import environ
root = environ.Path(__file__) - 2 # three folder back (/a/b/c/ - 3 = /)
env = environ.Env(DEBUG=(bool, False),) # set default values and casting
environ.Env.read_env() # reading .env file

SITE_ROOT = root()

DEBUG = env('DEBUG') # False if not in os.environ
TEMPLATE_DEBUG = DEBUG

STATIC_URL = '/static/'

wsgi.py档案：

from app_name.settings import env, SITE_ROOT 
LOCAL = env('LOCAL')

# if not in the local development env
if not LOCAL:
    import sys
    import site

    path = SITE_ROOT
    #path='/var/www/vhosts/xxxx/xxxx'
    if path not in sys.path:
        sys.path.append(path)

    #Add the site-packages of the chosen virtualenv to work with
    site.addsitedir(env('PYTHON_ENV_SITE_PACKAGES_DIR'))

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app_name.settings")

application = get_wsgi_application()

为什么会发生这种情况，我该如何解决或排除故障？

修改我在评论中为每个请求发布WSGI配置文件。

<IfModule !wsgi_module>
LoadModule wsgi_module modules/mod_wsgi.so
</IfModule>

<VirtualHost *:80>
    # This is name based virtual hosting. So place an appropriate server name
    #   here. Example: django.devsrv.local
    ServerName  www.app_name.store
    ServerAlias app_name.store

    WSGIDaemonProcess app_name display-name=%{GROUP} python-home=/var/www/vhosts/xxxx/xxxx-env/ python-path=/var/www/vhosts/xxxx/xxxx-site/
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup app_name

    # Insert the full path to the wsgi.py-file here
    WSGIScriptAlias / /var/www/vhosts/xxxx/xxxx-site/xxxx/wsgi.py process-group=app_name

    <Directory /var/www/vhosts/xxxx/xxxx-site>
        Require all granted
    </Directory>

    Alias /static/ /var/www/vhosts/xxxx/xxxx-site/static/

    <Directory /var/www/vhosts/xxxx/xxxx-site/static/>
    Order deny,allow
    Allow from all
    </Directory>

    Alias /media/ /var/www/vhosts/xxxx/xxxx-site/media/
    <Directory /var/www/vhosts/xxxx/xxxx-site/media/>
    Order deny,allow
    Allow from all
    </Directory>

</VirtualHost>

使用WSGI和Virtualenv为Django服务时找不到模块
