MySQL Host ' XXXXXX ' is blocked because of many connection errors

ERROR 1129 (00000): Host ' XXXXXX ' is blocked because of many connection errors; Unblock with ' mysqladmin flush-hosts '
I checked the information.
This indicates that MYSQLD has been given a large number (max_connect_errors) of host ' hostname ' in the Midway interrupted connection request. After max_connect_errors a failed request, MYSQLD identified an error (like a hacker attack) and blocked further connections to the site until someone executed the command mysqladmin flush-hosts.
By default, mysqld blocks a host after 10 connection errors. You can easily adjust it by starting the server like this: set global max_connect_errors=1000;
Note that for a given host, if you get this error message, you should first check the TCP/IP connection for that host for any problems. If your TCP/IP connection is not running, increasing the value of the max_connect_errors variable will not help you!
