我使用mod_wsgi在数字海洋上安装了Django，但它有500个内部服务器错误。当我查看apache错误日志时，这是我得到的：

[Tue Dec 17 02:38:09 2013] [error] [client 175.110.123.23] ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb

在最后一行，它说ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb。据我所知，需要安装python的MySQLdb模块。但我在本地机器上也有这样的问题，但那不是500内部服务器错误。现在也在服务器上，它是Debug true。因此，不要认为500内部服务器错误是由MySQL DB模块引起的。

所以任何想法导致500内部服务器错误的问题是什么？我认为mod_wsgi配置存在一些问题，但不确定。如果您有任何想法，请告诉我。

答案 0 :(得分：1)

需要一个系统包在linux上安装MySQLdb（使用aptitude），您可以使用以下命令安装它：

python-mysqldb - MySQL的Python接口

  1. sudo apt-get install python-mysqldb
  2. pip install MySQL-python
