Hello,
I tried to install Mediawiki together with MySQL (even if I want to port
Mediawiki to PostgreSQL).
I took the MySQL-4.0.18, apache-1.3.28 and php-4.2.3 source.
For Mediawiki installation I took the index.php script in the wiki/config/
directory (web-based installation). This all went well until the first start
of the index.php script in the main directory. Here I have now some problems
with connecting to the database.
The following message occurs, when I load the index.php file:
************Start error message ***********************

Sorry! The wiki is experiencing some technical difficulties, and cannot
contact the database server.
*************End Error Message****************
Has anyone an idea, what the problem for this Error-Messages could be? I
wouldn's spent to much time in finding problems with MySQL. My goal is to
come up with Postgres as fast as possible......
Best regards,
Bernhard

Hi Bernhard,
it's very arguable what exactly is meant by "more professional".
Generally speaking, speed is MySQL's forte, and is also what MediaWiki
has a great need for (particularly with Wikipedia). The magazine
articles you've read were probably referring to some of the more
"enterprise" features (MySQL for a long time did not support
transactions, and replication was dubious at best) which MediaWiki
doesn't really need. I don't personally think there is much benefit in
letting the code use Postgres, but if you're willing to put in the
effort - hey, great, send a patch.
As for the MediaWiki table structure, while I'm sure we can help with
problems you might encounter, it might be easier for you to install,
temporarily, MySQL on one of your machines. MySQL binaries are available
for a slew of operating systems and architectures, so it shouldn't take
very long.
Cheers,
Ivan

In every article about Open Databases I read, that Postgres is a more
professional database than MySQL, so I wonder that there is no interrest
in suporting also Postgresql, or is there also interrest?
However, I have a running Postgres database and I want to run also a
Wiki
Wiki. The question for me is now if I should take PHPWiki which has
Postgres
support or if I should spend some time in enhancing MediaWiki.
At the moment, it seams that MediaWiki has more interesting features
than
PHPWiki.......
So my first question: Was there a demand for Postgres in the past?
Second: Is there anyone who can suport me if I have some question about
MySQL
(table-structure of MediaWiki) support of MediaWiki? I don't want to
install
also MySQL on some of my computers......
Best regards,
Bernhard
