Opis

OceanBase supports communication encryption to ensure that traffic between nodes cannot be eavesdropped or tampered with. Runs obclient with the connection options in OB_CONN (default "-h127.0.0.1 -P2881 -uroot@sys"); point it at the MySQL-mode tenant being assessed and supply the password via OB_CONN (-p...) or a [client] section in ~/.my.cnf. Passes when sql_protocol_min_tls_version is TLSv1.2 or TLSv1.3 on all OBServer nodes (none, any, TLSv1 or TLSv1.1 fail). Mismatched values across nodes fail because each row is checked.

Kako se proverava

Metod provere: SQL upit

sql_query

out=$(obclient ${OB_CONN:--h127.0.0.1 -P2881 -uroot@sys} -N -B -e "SELECT CASE WHEN COUNT(*) > 0 AND SUM(CASE WHEN value IN ('TLSv1.2', 'TLSv1.3') THEN 0 ELSE 1 END) = 0 THEN 'compliant' ELSE 'noncompliant' END FROM oceanbase.GV\$OB_PARAMETERS WHERE name = 'sql_protocol_min_tls_version'" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

ALTER SYSTEM SET sql_protocol_min_tls_version = 'TLSv1.2'; (or 'TLSv1.3') and confirm the value on every OBServer with SHOW PARAMETERS LIKE 'sql_protocol_min_tls_version';
