Mysql 远程连接异常一"Host 'xxx' is blocked because of many connection errors"

Mysql 远程连接错误一"Host 'xxx' is blocked because of many connection errors"
错误：Host 'xxx' is blocked because of many connection errors
原因：MySQL服务器已经从某个host接收了大量中途终止的连接，于是决定终止继续接收来自该host的连接。允许最大的连接错误数为max_connect_errors，通过show variables like max%命令可以查询，一般为10。
解决方法：

mysql -uroot -pxxx;
flush hosts;
