Mysql安装问题

在安装mysql的时候，就会遇到以下错误。遇到错误不可怕，怕的就是被错误所击倒！
The security settings could not
be applied to the database because the connection has failed with the following
error.
Error Nr. 1045
Access denied for user ‘root’@‘localhost’
(using password: YES)
If a personal firewall is running on your machine,
please make sure you have opened the TCP port 3306 for connections. Otherwise no
client application can connect to the server. After you have opened the port
please press [Retry] to apply the security settings.
If you are re-installing
after you just uninstalled the MySQL server please note that the data directory
was not removed automatically. Therefore the old password from your last
installation is still needed to connect to the server. In this case please
select skip now and re-run the Configuration Wizard from the start
menu.
