How to solve it?

First, check mysql host:port is reachable by php, along with the mysql authentication - user, location, password.
Second, check if application/config/config.php.sample is renamed to 'config.php'.
Third, open config.php, find '$config['db_auth_host'] = '127.0.0.1'; and the following arguments till $config['realmlists']. Set them right.
Above all, you should know how database works, if not, Solve it first.
