How can I install wordpress ?

[arastirici]

I use php5.2.6, mysql5, apache2 and ispconfig 2.2.25 on opensuse11.
I have many domains. It generally works well.
I have a new domain which uses wordpress.
I am not able to install wordpress for this domain.
it can establish with its mysql database.
my web browser says cannot display page.
if it can't establish a connection to database, it already notifies as below;
"Error establishing a database connection"
I can't see any error in phperrorlog or http-access-error.log.

How can I install wordpress ?

Thanks

Make sure you have the right database info in the file wp-config.php

[arastirici]

it connects to right database. for instance if I change the password of the database in wp-config.php. it gives an error because of couldn't establish to the database.

Can you connect with the same username and password to MySQL on the command line?
mysql -u username -p

[arastirici]

I can connect to the database with mysql -u user -ppassword
after put down the user and pass for the database at wordpress's setup page,
it says "all right sparky click here to setup " on worppress setup page.

when I clicked the setup button. I arrived in a blank web page.
I don't get any error in php log file.

I set value of zend.ze1_compatibility_mode "Off"

after restart apache, the problem has gone.
