Django + Apache与mod_wsgi。无法加载MySQLdb

时间:2012-02-28 02:34:31

标签: django apache mod-wsgi mysql-python

我目前在Apache上设置虚拟主机以尝试在django.localhost

主持我的Django项目

我的apache配置是正确的:

hobbes3@hobbes3:~/Sites/mysite$ apachectl configtest
Syntax OK

这是我的~/Sites/mysite/apache/apache_django_wsgi.conf文件,该文件包含在/etc/apache2/httpd.conf

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName django.localhost
    ErrorLog "/var/log/apache2/django-error_log"

    <Directory /Users/hobbes3/Sites/mysite>
        AllowOverride All
        Options Indexes FollowSymLinks
        Order allow,deny
        Allow from all
    </Directory>

    WSGIDaemonProcess django.localhost processes=1 threads=1 maximum-requests=1
    WSGIProcessGroup django.localhost

    WSGIScriptAlias / "/Users/hobbes3/Sites/mysite/apache/django.wsgi"
</VirtualHost>

这是我的/User/hobbes3/Sites/mysite/apache/django.wsgi

import os
import sys

paths = [ '/Users/hobbes3/Sites/mysite',
          '/usr/local/lib/python2.7/site-packages',
]

for path in paths :
    if path not in sys.path :
        sys.path.append( path )

os.environ[ 'DJANGO_SETTINGS_MODULE' ] = 'settings'

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

我知道/usr/local/lib/python2.7/site-packages' I have both './django' and './MySQL_python-1.2.3-py2.7-macosx-10.4-x86_64.egg。我相信我使用homebrew安装了它们。因此/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages也指向同一个位置(我不知道如何)。

当我运行python manage.py runserver时,我知道MySQLdb正在运行,但我尝试访问django.localhost,我收到两个类似的错误,无法找到MySQLdb(我被截断)可读性的日期和时间):

很抱歉长错误日志,但我想完成。我为此配置做错了什么?

将WSGI脚本中的PYTHON_EGG_CACHE设置为Apache运行代码的用户可以写入的位置。
