TMA-MARIADB-9.2

Ensure 'MASTER_SSL_VERIFY_SERVER_CERT' is enabled

AltaNivel 1Automatizadamariadb

Descripción

On the MariaDB REPLICA, the setting MASTER_SSL_VERIFY_SERVER_CERT indicates whether the REPLICA should perform server certificate verification of the PRIMARY's certificate. Checks every replication connection in SHOW ALL REPLICAS STATUS; passes on servers that are not replicas. Runs mariadb -NBe with the client defaults: as root on the server the unix_socket plugin usually authenticates; otherwise put an administrative account in ~/.my.cnf (mode 0600), not MYSQL_PWD (see 1.4/1.6).

Cómo se verifica

Método de auditoría: Consulta SQL

sql_query

out=$(mariadb -Ee "SHOW ALL REPLICAS STATUS" 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk -F': ' '/Master_SSL_Verify_Server_Cert:/{if($2!="Yes")b++} END{print b?"noncompliant":"compliant"}'

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

STOP REPLICA; CHANGE MASTER TO MASTER_SSL_VERIFY_SERVER_CERT = 1; START REPLICA; (per connection name for multi-source replication).
