can't get database to connect during magento installation - using wizard

I’m trying to install magento on my live web server , I’ve checked the server with magento-check.php and thats fine.

I’ve set up a mysql db with the user name and password the of the mysql开发者_如何学Go server

I’ve entered this into the host* along with the username and password into the installation wizard but it will not connect. ?

Can anybody help me with this I know it seems so simple ??

The problem was that the server i was trying to install magento onto did not support mysql InnoDB - only MyISAM , Magento uses the InnoDB engine. I have now installed several versions of Magento on 1and1 servers.
