I know it, and that's the proper way, but if you want quick and dirty, try to modify these codes in file configuration.php
$mosConfig_absolute_path: This is the absolute server path to your new Joomla! installation. It will probably look something like "/path/to/joomla/installation".
$mosConfig_cachepath: This is the absolute server path to the cache for your Joomla! installation. It will probably look something like "/path/to/joomla/installation/cache".
$mosConfig_live_site: This is your website's url. It will be something like "[
www.yoursite.com"];.
$mosConfig_host: This is the location of the server that hosts your MySQL database. For most instances, this value will be "localhost". If you are unsure, ask your hosting provider.
$mosConfig_db: This is the name of your MySQL database.
$mosConfig_user: This is the database user name. Make sure this user has all privileges on your database.
$mosConfig_password: This is the password for your MySQL database user.
