is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'Connection closed by foreign host.

"host is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'Connection closed by foreign host" 这个错误信息表明由于连接错误过多，主机被阻塞了，并提示使用'mysqladmin flush-hosts'命令来解除阻塞。解决这个问题有两种方法。第一种方法是在安装的bin目录下使用命令'mysqladmin -u root -p flush-hosts'，然后输入密码，即可完成清除缓存的操作。第二种方法是进入mysql控制台，并执行'flush hosts;'命令来清除缓存。需要注意的是，使用第一种方法可能会导致mysql握手协议异常，每异常一次max_connect_errors数量就会增加1，当达到设置的最大值后，该主机将无法连接到mysql数据库。所以，建议在清除缓存之前，先确认数据库连接是否正常，以避免出现无法连接的情况。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
