带有pyramid&pyramid_beaker的apache+mod_wsgi的文件权限问题

Question

我正在尝试设置一个金字塔应用程序。我使用的是wsgi和apache2。

我一直收到内部服务器错误，apache日志的内容是

 mod_wsgi (pid=11200): Exception occurred processing WSGI script '/home/ubuntu/modwsgi/env/pyramid.wsgi'.
 Traceback (most recent call last):
   File "/home/ubuntu/modwsgi/env/lib/python2.6/site-packages/pyramid-1.3-py2.6.egg/pyramid/router.py", line 191, in __call__

     makedirs(head, mode)
   File "/usr/lib/python2.6/os.py", line 157, in makedirs
     mkdir(name, mode)
 OSError: [Errno 13] Permission denied: 'beaker_dir'

我可以使用简单的pserve为页面提供服务，并在终端上运行wget http://localhost:6543/user/form。它可以很好地处理表单下载。但在浏览器上，我得到了500错误。

我正在使用EC2来托管应用程序。

在app:main stanza中，我使用了以下代码：

session.type = file
session.data_dir = beaker_dir
session.key = mvc
session.encrypt_key = mysecretencryptionkey
session.validate_key = mysecretvalidationkey
session.cookie_on_exception = true

感谢您的阅读

Answer 1

为以下内容提供绝对路径：

session.data_dir = beaker_dir

当前工作目录可以是任何内容，通常是'/'，因此路径将是错误的。
