centos - apache配置django报错：cannot be loaded as Python modules

平台：Centos5 ECS上的
django版本1.6
apache版本2.2
通过mod_wsgi将django项目配置到apache上一直没有成功,单独测试wsgi可以访问，django单独跑runserver也可以跑通
项目路径：

/var/www/html
`-- mysite
    |-- manage.py
    |-- mysite
    |   |-- __init__.py
    |   |-- __init__.pyc
    |   |-- media
    |   |-- settings.py
    |   |-- settings.pyc
    |   |-- static
    |   |-- urls.py
    |   |-- wsgi.py
    |   `-- wsgi.pyc
    `-- wsgi
        `-- django.wsgi

通过startproject创建的项目，单独runserver可以跑通，新增了wsgi文件夹以及django.wsgi配置文件

httpd.conf文件中添加了：

LoadModule wsgi_module modules/mod_wsgi.so

   ServerAdmin root@localhost
   DocumentRoot /var/www/html
   ServerName 121.40.202.235
   ErrorLog "logs/error_log"
   CustomLog "logs/access_log" common

   WSGIScriptAlias / /var/www/html/mysite/wsgi/django.wsgi
   
       Order deny,allow
       Allow from all
   

django.wsgi文件：

import os
import sys
import django.core.handlers.wsgi

os.environ['DJANGO_SETTINGS_MODULE']= 'mysite.settings'
sys.path.append('/usr/local/lib/python2.7/site/packages')
app_path = os.path.dirname(__file__)
if app_path not in sys.path:
        sys.path.append(app_path)

application =django.core.handlers.wsgi.WSGIHandler()

重启apache服务器没有问题，访问网址后报错日志为：
