Ensure `max_connect_errors` Is Reasonably Set

NiskaNivo 2Automatskatdsql

Opis

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).

Kako se proverava

Metod provere: SQL upit

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT CASE WHEN @@global.max_connect_errors <= 100 THEN 'compliant' ELSE 'noncompliant' END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

SET GLOBAL max_connect_errors = 100;
