这是我的wsgi.py文件：

import os 

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

# This application object is used by any WSGI server configured to use this 
# file. This includes Django's development server, if the WSGI_APPLICATION 
# setting points here. 
from django.core.wsgi import get_wsgi_application 
application = get_wsgi_application()

这是我的.env文件：

# Required 
SECRET_KEY='password1' 
WEB_PORT=8000 
EMAIL_BACKEND='django.core.mail.backends.console.EmailBackend' 
GOPATH=$VIRTUAL_ENV 
WEB_SECRET_KEY='password1' 
STORAGE_URL=postgres://ubuntu:password@localhost:5432/botbot 
REDIS_PLUGIN_STORAGE_URL=redis://localhost:6379/0 
REDIS_PLUGIN_QUEUE_URL=redis://localhost:6379/1 
PUSH_STREAM_URL=http://localhost:8080/pub/?id={id}

# SMTP_URL=smtp://user:pass@host:port 
# SMTP_TLS=True 
# ALLOWED_HOSTS=host1,host2 
# INCLUDE_DJANGO_ADMIN=False 
# EXCLUDE_NICKS=nick1,nick2

这是我的apache conf文件：

<VirtualHost *:80> 
        ServerName server.test.com 
        ErrorLog ${APACHE_LOG_DIR}/error.log 
        SetEnv WEB_SECRET_KEY password1 
        CustomLog ${APACHE_LOG_DIR}/access.log combined 
        DocumentRoot /srv/botbot/src/botbot 
        <Directory /srv/botbot/src/botbot/botbot> 
                <Files wsgi.py> 
                        Require all granted 
                </Files> 
        </Directory> 

        WSGIDaemonProcess botbot python-path=/srv/botbot/src/botbot/botbot:/srv/botbot/lib/python2.7/site-packages 
        WSGIProcessGroup botbot 
        WSGIScriptAlias / /srv/botbot/src/botbot/botbot/wsgi.py 

</VirtualHost>

这是我尝试构建的应用：https://github.com/BotBotMe/botbot-web。

正如您所看到的，我已尝试在apache conf中设置SetEnv变量，但没有运气。我甚至不确定这是否正确，无论我做什么，我仍然会收到以下错误。

Answer 1

我相信您应该尝试使用SetEnvIf指令，因为阅读apache文档：

The internal environment variables set by this directive are set after   
most early request processing directives are run, such as access 
control and URI-to-filename mapping. If the environment variable you're 
setting is meant as input into this early phase of processing such as 
the RewriteRule directive, you should instead set the environment  
variable with SetEnvIf.

如果您想通过SetEnv进行设置，它可能在启动时不适用于django应用程序。

但是你可以做的最好的事情就是在一些预运行的脚本中设置这个env变量。

快乐的编码！

Answer 2

我最后将以下行添加到我的wsgi.py文件中：

os.environ['WEB_SECRET_KEY'] = 'password'

其中＆＃39;密码＆＃39;等于._Sv文件中为WEB_SECRET_KEY变量指定的密码字符串。

我还必须以递归方式将/ srv目录（包含应用程序而不包含其他内容）添加到www-data用户。

本文档很有帮助：https://gist.github.com/GrahamDumpleton/b380652b768e81a7f60c

尝试配置django应用程序以使用mod_wsgi
