MediaWiki 1.8.2 Installation

Don't forget security updates! Keep an eye on the low-traffic release announcements mailing list.
Checking environment...

Please include all of the lines below when reporting installation problems.
PHP 5.1.6 installed
Found database drivers for: MySQL PostgreSQL
PHP server API is apache; ok, using pretty URLs (index.php/Page_Title)
Have XML / Latin1-UTF-8 conversion support.
PHP is configured with no memory_limit.
Have zlib support; enabling output compression.
Couldn't find Turck MMCache, eAccelerator or APC. Object caching functions cannot be used.
Found GNU diff3: /usr/bin/diff3.
Found GD graphics library built-in, image thumbnailing will be enabled if you enable uploads.
Installation directory: /Library/WebServer/Documents/wiki
Script URI path: /wiki
Environment checked. You can install MediaWiki.

DB connection error: Unknown error (<my DNS hostname>)
Comment 1 Don Mathis 2006-10-26 21:00:43 UTC
Me again adding commentary: 
This is on an Intel mac OS X Server machine.
The installation show above successfully creates the wikidb database in mySql (v.4.1.13) and creates the user 'wikiuser' and gives 
it access to the new db.  But it does not create the LocalSettings.php file as it claims:
            "After setup, a file called LocalSettings.php is created in the "config" directory."

I've seen similar posts before, but no solutions.  I saw a similar post dismissed as a "configuration problem", but this can't be a 
configuration problem because I haven't even gotten to the configuration step yet, and php and mySql are otherise perfectly ok.

please help?
Comment 2 Brion Vibber 2006-10-27 10:31:09 UTC
You might want to investigate the connection problem, for instance by trying to connect 
to the database with the parameters you gave.
Comment 3 Andrew Garrett 2006-11-02 06:20:19 UTC
Filer of bug has given no additional information a week after the bug was filed;
and there's no evidence this is a MediaWiki software issue. Resolving as INVALID.
Comment 4 Don Mathis 2006-11-02 14:14:07 UTC
I can connect to the database with the command line

mysql --user=wikiuser -p

which prompts me for the password, or by supplying the password with 

mysql --user=wikiuser --password=<password>

But apparently this is not how the wiki attempts to access the database.
Comment 5 Don Mathis 2006-11-03 18:27:16 UTC
When I reinstall using the webpage http://myhostname/wiki, it seems to be happy, detecting that the database is 
already set up, but then I get the same mysterious connection error at the end.  Can someone tell me how mediawiki is 
trying to connect to the database?  Thanks.

Comment 6 Rob Church 2006-11-03 22:28:23 UTC
Check the error log; MediaWiki uses the standard PHP libraries depending upon
the driver in use.
Comment 7 Andrew Garrett 2006-11-03 23:04:47 UTC
Changing the priority down. This is NOT really a software issue - it's more
support for a customer who hasn't got their environment set up right.
Comment 8 Don Mathis 2006-11-08 17:08:13 UTC

Where is the error log?

Closing as INVALID. No response from customer in over 2 years, and it wasn't really a bug in the software to begin with.
