我一直在嘗試使用MOD_WSGI將DJANGO-REST WS集成到Apache中，但是在嘗試應用所有調試技術和不同的wsgi腳本一段時間後，幫幫我。DJANGO-REST，MOD_WSGI和APACHE集成問題
Server版本：阿帕奇/ 2.2.22（Ubuntu的） 的Python 2.7.3（默認情況下，2014年2月27日，19點58分35秒） mod_wsgi的版本：3.3
目前我WSGI文件如下：
"""

It exposes the WSGI callable as a module-level variable named ``application``.

sys.path.append('/usr/local/ZigHomeWS')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "zighome_rest.settings")
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
和我的虛擬主機被配置如下：

我必須承認，添加「/usr/local/lib/python2.7/site-packages/django」只是一種絕望的措施，最終導致無所事事。
我應該提到的一點是，儘管它對解決方案沒有任何影響，但核心系統實際上是一個我用SWIG包裝的C++系統。
不用說，它正在使用Django-REST開發環境。
最後但並非最不重要的，如果在WSGI腳本文件更改這兩行：
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
這些：
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
這反而崩潰日誌中提供的堆棧跟蹤文件：
[Sat Sep 27 19:44:10 2014] [error] [client X.X.X.X] Premature end of script headers: django.wsgi
我最終應用了推薦的調試技術，但不幸的是，牛逼非常有幫助的，因爲GDB的堆棧跟蹤只給我：
(gdb) cont

調查：
所以...我剛剛意識到的東西。
從我從幾個網站閱讀在網絡上，我應該是真的使用這個電話：
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
的WSGI腳本。由於這兩行代碼一直在崩潰，我無法快速完成任務，所以我記得打電話給我創建的任何其他Web服務和VOILA！有用。 （不知道爲什麼我以前沒有嘗試過......固執我猜）
現在，兩個網絡服務之間的主要區別之一就是它只解析一些XML文件並添加數據到sqlite3數據庫和另一個（崩潰的）數據庫啓動整個系統，這意味着創建多個線程等等。
因此，我現在正在尋找任何線程相關的記錄問題，我可以找到modwsgi。
我希望你能爲我提供一些幫助
謝謝
請用您的設置文件更新問題。 – 2014-09-28 12:21:01
我編輯了添加settings.py文件配置請求的問題。 – cvicente 2014-09-28 12:31:48
從錯誤看來，你應該在某些文件中使用'gettext_lazy'時使用'gettext';從你的設置不明確。但是，檢查您的其他應用程序。如果你從'INSTALLED_APPS'註釋掉'rest_framework'，你還會得到錯誤嗎？ – 2014-09-28 13:03:51
