mysql Error Nr. 2003报错的解决方案

报错信息：

Error Nr. 2003
Can't connect to MySQL server on 'localhost'(10061)

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.

 

 

解决办法：

删除Tcp/ip协议中的IPv6，Ping localhost回归正常，重新配置MySQL Instance成功。
