Question

我正在使用Apache，mod_wsgi，Virtualenv和Postgres在Ubuntu服务器（v14.04）中配置Django 1.7项目。在所有配置之后，我有一个内部错误，使用此日志：

django.core.exceptions.ImproperlyConfigured：加载psycopg2时出错模块： /home/ubuntu/VirtualEnvs/env1/lib/python2.7/site-packages/psycopg2/_psycopg.so：未定义的符号：_Py_ZeroStruct

回溯日志错误：

mod_wsgi (pid=13365): Target WSGI script '/var/www/html/domain.com/projectname/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=13365): Exception occurred processing WSGI script '/var/www/html/domain.com/projectname/wsgi.py'.

During handling of the above exception, another exception occurred:

Apache .conf文件：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName domain.com
    ServerAlias www.domain.com
    DocumentRoot /var/www/html/domain.com
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

WSGIScriptAlias / /var/www/html/domain.com/projectname/wsgi.py
WSGIPythonPath /var/www/html/domain.com:/home/ubuntu/VirtualEnvs/env1/lib/python2.7/site-packages

<Directory /var/www/html/domain.com/projectname>
    <Files wsgi.py>
        Order deny,allow
        Require all granted
    </Files>
</Directory>

Alias /media/ /var/www/html/domain.com/media/
Alias /static/ /var/www/html/domain.com/static/

<Directory /var/www/html/domain.com/static>
    Require all granted
</Directory>

<Directory /var/www/html/domain.com/media>
    Require all granted
</Directory>

项目wsgi文件（/var/www/html/domain.com/projectname/wsgi.py）：

import os, sys

sys.path.append('/var/www/html/domain.com')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "projectname.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

psycopg2模块已成功安装，可以正常访问：

python
import psycopg2

知道这里可能会发生什么吗？

谢谢。

使用virtualenv和mod_wsgi
