TMA-OCEANBASE-3.2.2

Only Approved Servers can Access

AltaNivel 1Automatizadaoceanbase

Descripción

Specify an allowlist of approved servers that can access to the cluster. 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. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Passes when _ob_ssl_invited_nodes is a non-empty, explicit list of trusted IPs/hosts on every OBServer (empty, None, ALL or 0.0.0.0/0 fail).
