Reason

The service deployed on the host was rejected because the database account was misconfigured, which caused the number of failed connections to the MySQL service to exceed the max_connection_errors parameter setting value (default 10) in a short period of time.

Solution method

Method 1:

Refresh the file that records the error report host

Mysqladmin-uroot-p-h292.168.1.1 flush-hosts

Or

Mysql > flush hosts

Note: the database master and slave server needs to determine which MySQL service has been rejected, refresh the corresponding server, or refresh them all if you are not sure.

Method 2:

Enter the database to increase the max_connection_errors parameter, or you can modify it in the my.cnf file, but you need to restart MySQL.

Mysql > show variables like'% max_connection_errors%'

Mysql > set global max_connect_errors = 1000

Mysql > show variables like'% max_connection_errors%'
