在 CentOS 中部署 Django-内部服务器错误 500

我的系统：

CentOS: 5.5 x86_64 GNU/Linux
Apache/2.2.16
mod_wsgi-3.2-1.el5.x86_64
python 2.6.6
django 1.2.3

我的文件example.wsgi：

#!/usr/local/bin/python
import os, site, sys

# add the virtual environment path
site.addsitedir('/home/admin/domains/example.com/env/lib/python2.6/site-packages')
site.addsitedir('/home/admin/domains/example.com/myproject')
site.addsitedir('/home/admin/domains/example.com')

# fix markdown.py (and potentially others) using stdout
sys.stdout = sys.stderr

#Calculate the path based on the location of the WSGI script.
project = os.path.dirname(__file__)
workspace = os.path.dirname(project)
sys.path.append(workspace)

os.environ['PYTHON_EGG_CACHE'] = '/home/admin/domains/example.com/.python-eggs'
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'
from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()

Apache 配置：

ServerRoot /etc/httpd

<VirtualHost 69.*.*.*:80 >
LoadModule wsgi_module /usr/lib64/httpd/modules/mod_wsgi.so

WSGIScriptAlias / /home/admin/domains/example.com/example.wsgi
WSGIDaemonProcess example user=admin processes=2 threads=25 display-name=%{GROUP}
WSGIProcessGroup example
WSGIApplicationGroup %{GLOBAL}

LogLevel debug

   <Directory /home/admin/domains/example.com>
      Order allow,deny
      Allow from all

 CustomLog /var/log/httpd/domains/example.com.bytes bytes
 CustomLog /var/log/httpd/domains/example.com.log combined
 ErrorLog /var/log/httpd/domains/example.com.error.log

</VirtualHost>

我可以执行“syncdb”并导入 PYTHONPATH 中的任何内容。当我运行 example.com 时，一切正常。但是当我运行 example.com/admin 时，它会出现问题：内部服务器错误 在 /var/log/httpd/domains/example.com.error.log 中调试：

[Sun Oct 03 00:01:08 2010] [error] [client 58.186.13.1] Premature end of script headers: example.wsgi

请帮我解决这个问题。非常感谢！

答案1

假设您可以正常运行应用程序，但尝试访问管理界面时失败，则 ERROR 500 很可能是由未捕获的异常引起的。如果您设置了DEBUG = True和TEMPLATE_DEBUG = True，settings.py您应该可以从异常中获得更好的信息（例如堆栈跟踪）。

答案2

尝试这个：

sys.path.append(project)

我遇到过类似的问题，并且已经用这种方法解决了。
