django：mod_wsgi無法打開項目目錄中的日誌文件

Question

我想用mod_wsgi部署我的項目。不幸的是，我得到：

我有我的項目中的/ etc進入/啓用站點的Apache2//：

SetEnv app_settings project.config.production 
WSGIDaemonProcess project user=project group=project threads=1 processes=1 home=/home/project/project python-path=/home/project 
<VirtualHost *> 
     ServerName project.internal 
     WSGIScriptAlias//home/project/project/wsgi/project.wsgi 
     WSGIProcessGroup %{GLOBAL} 
</VirtualHost> 

我的日誌文件應該存儲在項目目錄內。我已經調查了一下，在project.log被打開之前，我運行os.getcwd（），它返回/。任何人都可以告訴我，我可能錯誤地配置了這種情況？

Answer 1

這不是一個很大的答案，但我設置我的網站只使用絕對路徑名，從settings.py拉入基本路徑。您可以在settings.py中使用非官方Django設置名稱的變量，只要您使用ALLCAPS_WITH_UNDERSCORES風格命名它們，就可以導入import settings這些變量。

IIRC，守護進程一般應使用絕對路徑名。顯然，使用相對路徑名可能是一個安全漏洞。

Answer 2

這不是路徑，而是關於權限。

apache用戶正在嘗試創建該日誌文件，因此您應該爲該目錄提供寫入權限。
