WordPress > Error

I followed all the steps from the Track 'Beginning WordPress' which I thought it is going to a smooth installation. But these error happens:

Error establishing a database connection This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down. Are you sure you have the correct username and password? Are you sure that you have typed the correct hostname? Are you sure that the database server is running?

Both Apache and MySQL are running. I also use the 'Set default MAMP ports'.

Ports: Apache - 8888 MySQL - 8889
