在执行配置时直接运行配置导向重新配置即可.
重新安装mysql后最后的apply security setting出错时,一般是因为卸载后删除不干净导致的.
可以把mysql重新卸载,并删除所有配置文件以及安装目录.(最后重新选择一个安装位置)
然后重新执行安装就可以了.
借鉴：
在安装mysql时，出现“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)” 解决办法：

在装mysql时，总是到最后启动的时候出错，出错内容如下：
就是最后的Apply security setting过不去
提示：
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.
解决方法：
1, 卸载MySQL
2, 删除MySQL的安装目录
3, 重新安装MySQL 就好了
