Ensure Connection Timeout Parameters Are Reasonable

MittelStufe 1Automatisierttdsql

Beschreibung

Idle connection timeout parameters (wait_timeout, interactive_timeout) control when idle connections are automatically closed. Excessively long timeouts increase the risk of connection hijacking. 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 wait_timeout and interactive_timeout are both 3600 seconds or less (300-600 recommended for production; the TDSQL default 28800 fails).

So wird geprüft

Prüfmethode: SQL-Abfrage

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT CASE WHEN @@global.wait_timeout <= 3600 AND @@global.interactive_timeout <= 3600 THEN 'compliant' ELSE 'noncompliant' END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

SET GLOBAL wait_timeout = 600; SET GLOBAL interactive_timeout = 600; and persist them in the parameter template.
