im试图在docker容器中的mariadb上启用SSL 我对/etc/mysql/my.cnf文件进行了以下更改
ssl-ca=/etc/certs/client-cert.pem
ssl-cert=/etc/certs/server-cert.pem
ssl-key=/etc/certs/server-key.pem
ssl_ca=/etc/certs/client-cert.pem
ssl_cert=/etc/certs/server-cert.pem
ssl_key=/etc/certs/server-key.pem
注意：我已经将变量名与-和_一起使用，因为我不确定使用哪种方案
我也在上述路径中提供了证书 这是“显示类似'％ssl％'的变量；”的结果
MariaDB [(none)]> show variables like '%ssl%';

它说未使用SSL，现在不知道是否启用了SSL，或者我是否缺少任何标志？还有如何确定其是否启用？
