ERROR 1129 (HY000): Host '192.168.7.210' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

一、問題現象

mysql遠程連接報錯

ERROR 1129 (HY000): Host '192.168.7.210' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

二、問題原因

一般max_connect_errors = 10，要調高錯誤連接的數量

三、解決方法

登錄到要連接的數據中，進行如下配置

mysql> show variables like 'max_connect_errors';
mysql> set global max_connect_errors = 1000;                       # 如果想長期生效，並修改my.cnf配置文件
mysql> flush hosts;
