MySQL MySQL показывает, что have_ssl отключен при установке сертификатов

Пытаюсь включить SSL на моем mariadb-сервере. Я следил за официальными документами mariadb, чтобы сгенерировать CA-key ca-cert server-key server-cert. Моя машина - debian 9 kvm vps с mariadb 10.1.37

Когда я запускаю SHOW VARIABLES LIKE '% ssl'; как root, я получаю следующий результат:

+---------------------+--------------------------------+
| Variable_name       | Value                          |
+---------------------+--------------------------------+
| have_openssl        | NO                             |
| have_ssl            | DISABLED                       |

| ssl_capath          |                                |

| ssl_crlpath         |                                |
| ssl_key             | /etc/mysql/ssl/server-key.pem  |
| version_ssl_library | YaSSL 2.4.4                    |

Я пробовал повторно -многократное создание сертификатов, в том числе с разными общими именами. Сертификаты устанавливаются в папке / etc / mysql / ssl /

. Я также пробовал запустить mysqld с параметром - ssl и добавить ssl = на в конфиге. Я не могу найти больше информации, связанной с этим, так как у меня YASSL вместо openssl, поскольку mariadb теперь компилируется с YASSL по умолчанию, если я чего-то не упускаю, а YASSL не работает с моими ключами?

Как я создал сертификаты и ключи:

openssl genrsa 2048 > ca-key.pem

openssl req -new -x509 -nodes -days 365000 \
      -key ca-key.pem -out ca-cert.pem

openssl req -newkey rsa:2048 -days 365000 \
      -nodes -keyout server-key.pem -out server-req.pem

openssl rsa -in server-key.pem -out server-key.pem

openssl x509 -req -in server-req.pem -days 365000 \
      -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 \
      -out server-cert.pem
