Linux 发行版升级后，WSGI 下的 Moin 抛出 500 个错误

我有一个摩因摩因实例安装在/opt/mydebianwiki；wiki 在 [wsgi] / [apache2] 下运行。我最近从 Debian Linux 6 (squeeze) 升级到了 Debian 7 (wheezy)；升级之前，我的摩因摩因实例运行良好。

然而，升级到 wheezy 之后，当我尝试访问该网站时开始出现 http 500 错误。

谷歌搜索让我找到了这个moin-用户线程，它说我可以直接运行su -c "moin --config-dir=/opt/mydebianwiki maint cleancache" www-data来修复该问题；然而，这同样不成功（请参阅问题底部的错误）。

我该如何解决这个问题？

data_dir "/org/mywiki/data" does not exist, or has incorrect ownership or

Make sure the directory and the subdirectory "pages" are owned by the web
server and are readable, writable and executable by the web server user
and group.

It is recommended to use absolute paths and not relative paths. Check
also the spelling of the directory name.

问题是，/opt/mydebianwiki/wikiconfig.py尽管我在命令中指定了该目录，但还是找不到我的本地 moin 配置moin ... maint cleancache。似乎/etc/moin当我运行 时，debian 的默认目录 ( ) 优先su -c "moin --config-dir=/opt/mydebianwiki maint cleancache" www-data。

我的解决方案是暂时重命名/etc/moin并运行该命令。这解决了问题：

root@tsunami:/opt/mydebianwiki# mv /etc/moin/ /etc/antimoin

root@tsunami:/opt/mydebianwiki# su -c "moin --config-dir=/opt/mydebianwiki maint 
 cleancache" www-data
