Django 不在 CentOS 上執行，但簡單的 wsgi 範例有效

我的 django.wsgi

import os
import sys

sys.path.append('/var/www/django')
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
os.environ['PYTHON_EGG_CACHE'] = '/var/www/django/myapp/.python-eggs'

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

http.conf

<VirtualHost 127.0.0.1:80>
   DocumentRoot /var/www/default
   ServerName localhost
   WSGIScriptAlias /myapp /var/www/django/myapp/apache/django.wsgi
   ErrorLog /var/www/django/myapp/logs/error_log
</VirtualHost>

Apache 錯誤說明如下

當我去 localhost/myapp 然後它給出了一些伺服器錯誤

ldd 的輸出：

我嘗試了 import sys 並沒有迅速出現錯誤，唯一的一行是

[Mon Jun 28 13:33:24 2010] [info] [client 127.0.0.1] mod_wsgi (pid=19384, process='', application='python.localhost|/application'): Loading WSGI script '/var/www/application/application.wsgi'.

什麼平台？為作業系統安裝了哪個確切版本的 Python？/opt/python2.6 中安裝了哪個確切版本的 Python？當您對已安裝的 mod_wsgi Apache 模組 .so 文件執行“ldd mod_wsgi.so”時會得到什麼？您是否偶然在配置中設置了 WSGIPythonHome？

總體而言，這看起來有點像您可能正在為不同版本選擇 Python 共享庫或安裝的 Python lib 目錄，並且存在不兼容性。

還可以返回並獲得一個 hello world WSGI 腳本而不是 Django，當它工作時添加到它：

import threading

所以你可以看看你是否可以創建一個獨立的測試來調查獨立於 Django 發生的事情。

對於 hello world 範例，請參見：

http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

最後，為了確保您沒有在同一個 Apache 實例中載入 mod_python 以確保良好的衡量標準。
