如何解决MySQL问题主机host_name被屏蔽
如果遇到下述错误，表示mysqld已收到来来自主机“host_name”的很多连接请求，但该主机却在中途中断。 由于出现很多连接错误，主机'host_name'被屏蔽。 可使用'mysqladmin flush-hosts'解除屏蔽。 允许的中断连接请求的数目由max_connect_errors系统变量的值
如果遇到下述错误，表示mysqld已收到来来自主机“host_name”的很多连接请求，但该主机却在中途中断。
由于出现很多连接错误，主机'host_name'被屏蔽。
可使用'mysqladmin flush-hosts'解除屏蔽。
允许的中断连接请求的数目由max_connect_errors系统变量的值决定。当超出max_connect_errors规定的连接请求时，mysqld将认为某处出错（例如，某人正试图插入），并屏蔽主机的进一步连接请求，直至执行了mysqladmin flush-hosts命令，或发出了FLUSH HOSTS语句为止。
在默认情况下，mysqld会在10次连接错误后屏蔽主机。你可以通过下述方式启动服务器来调整该值：
<ccid_code>shell> mysqld_safe --max_connect_errors=10000 &</ccid_code> Copy after login |
如果在给定主机上遇到该错误，首先应核实该主机的TCP/IP连接是否正确。如果存在网络问题，增加max_connect_errors变量的值不会有任何好处。
