Django + dbxml + Apache =問題。任何解決方案

我試圖設置一個使用WSGI的Django應用程序。這工作正常。但是，我在使用BDB XML的Django應用程序中遇到了一些問題。我的Apache配置如下：Django + dbxml + Apache =問題。任何解決方案

Listen 8000 
WSGISocketPrefix /tmp/wsgi 
<VirtualHost *:8000> 
    ServerName <server name> 
    DocumentRoot <path to doc root> 

    LogLevel info 

    WSGIScriptAlias/<path to wsgi> 
    WSGIApplicationGroup %{GLOBAL} 
    WSGIDaemonProcess debug threads=1 
    WSGIProcessGroup debug 
</VirtualHost>

不過，我還是發現了以下錯誤：

DB_ENV->repmgr_stat interface requires an environment configured for the replication subsystem 
[error] child died with signal 11

我的環境被打開：

environment = DBEnv() 

environment.open(
    <absolute db env path>, 
    DB_CREATE|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_MPOOL, 
    0 
)

我使用：

python 2.6.2
Apache 2.2的
Ubuntu 9.04的
的dbXML 2.5.13從源代碼編譯（這樣的libdb-4.8，bsddb3，所有爵士樂）

我看到阿帕奇似乎鏈接到的libdb-4.6。這是一個問題嗎？

ldd /usr/sbin/apache2 | grep libdb 
libdb-4.6.so => /usr/lib/libdb-4.6.so (0xb7c01000)

第一步將設置：

LogLevel info

，並期待在錯誤日誌記錄，以驗證它實際上是被在主解釋器中運行。爲此，記錄的應用程序組應該是加載WSGI腳本的消息中的空字符串。

還有一件事要做的就是在守護進程模式下運行並附加gdb並嘗試捕獲堆棧跟蹤以協助調試。請參閱：

感謝您的答覆。我確認應用程序組是空字符串。如果有幫助，我已經從gdb添加了回溯。 – Jason 2009-11-04 13:36:51

您是使用單線程還是多線程配置運行？也就是說，你是否在嵌入式模式下使用預製件或工作器MPM或守護進程模式運行，如果是，則使用WSGIDaemonProcess的參數。 – 2009-11-04 22:58:56

我添加了完整的apache配置。這有幫助嗎？ – Jason 2009-11-13 14:59:52
