用debian的apt源安装mediawiki出错

hqking

安装mediawiki, 系统是debian testing，用它自己的安装包，按说很简单。可是在页面设置完后出现这样的信息。

# PHP 5.2.0-10 installed
# Found database drivers for: MySQL
# PHP server API is apache2handler; ok, using pretty URLs (index.php/Page_Title)
# Have XML / Latin1-UTF-8 conversion support.
# PHP's memory_limit is 20M. If this is too low, installation may fail!
# Have zlib support; enabling output compression.
# Neither Turck MMCache nor eAccelerator nor APC are installed, can't use object caching functions
# Found GNU diff3: /usr/bin/diff3.
# Found ImageMagick: /usr/bin/convert; image thumbnailing will be enabled if you enable uploads.
# Installation directory: /var/lib/mediawiki1.7

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /usr/share/mediawiki1.7/includes/Database.php on line 620
A database query syntax error has occurred. The last attempted database query was: "(SQL query hidden)" from within function "". MySQL returned error "0: "

这里 MySQL returned error "0: " 有点小强的，不知道什么意思。MySQL貌似没有这么个error code。网上查也没法查到这个error code。

另在README.Debian 里这样说的
Configuration:
        The configuration uses an easy web-based system ; just go to this URL :
                http://www.myserver.org/mediawiki/config/index.php
        (replace by your own servername)
        Then just copy the generated config to the real system location :
                mv /var/lib/mediawiki1.7/config/LocalSettings.php \
                 /etc/mediawiki1.7
        After being configured, you should begin your surf on your new wiki
        using this url:
                http://www.myserver.org/mediawiki
        (replace by your own servername)
        Enjoy !!!

可现实是/var/lib/mediawiki1.7/config/里面没有生成那个php。应该就是配置最后报错引起的。

说明，我不懂php的，所以不高兴花大功夫从看那个620行出发找问题。
