Host '100.66.2.1' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'

根据引用\[1\]和引用\[2\]的内容，当一个IP在短时间内产生太多中断的数据库连接时，会导致该IP被阻塞，并出现"Host is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'"的错误提示。为了解决这个问题，可以使用mysqladmin命令执行"flush-hosts"来解除IP的阻塞。另外，根据引用\[3\]的内容，还可以通过创建事件定时器来定期执行"flush-hosts"操作，以避免频繁手动执行该命令。
