Ensure `max_connect_errors` Is Reasonably Set

低等級 2自動化tdsql

說明

max_connect_errors controls the threshold of consecutive connection errors from the same host after which MySQL automatically blocks subsequent connections from that host. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Passes when max_connect_errors is 100 or less (TDSQL default 2000).
