public key ssl error when try to connect to mysql

In my laboratory I use rundeck to schedule the execution of my scripts, and rundeck uses mysql 8 as a database, but recently rundeck cannot start due to the following error: "java.sql.SQLTransientConnectionException: Could not connect to address=(host=localhost)(port=3306)(type=master) : RSA public key is not available client side (option serverRsaPublicKeyFile not set)"

However, I have already made the settings in both rundeck and mysql so as not to request SSL for the connection.

MYSQL:

SHOW VARIABLES LIKE 'require_secure_transport';

+--------------------------+-------+

| Variable_name | Value |

+--------------------------+-------+

| require_secure_transport | OFF |

+--------------------------+-------+

1 row in set (0.00 sec)

mysql> SHOW VARIABLES LIKE 'ssl%';

+---------------------------+-------+

| Variable_name | Value |

+---------------------------+-------+

| ssl_ca | |

| ssl_capath | |

| ssl_cert | |

| ssl_cipher | |

| ssl_crl | |

| ssl_crlpath | |

| ssl_fips_mode | OFF |

| ssl_key | |

| ssl_session_cache_mode | ON |

| ssl_session_cache_timeout | 300 |

+---------------------------+-------+

10 rows in set (0.00 sec)

mysql> SHOW VARIABLES LIKE '%ssl';

+---------------+----------+

| Variable_name | Value |

+---------------+----------+

| have_openssl | **DISABLED **|

| have_ssl | **DISABLED **|

+---------------+----------+

2 rows in set (0.00 sec)

RUNDECK:

dataSource.url=jdbc:mysql://localhost/rundeck?autoReconnect=true&useSSL=false

Any ideas to fix it?

Solution:

Add the following param in your datasource string: allowPublicKeyRetrieval=true

Like this:

dataSource.url=jdbc:mariadb://mysql/rundeck?autoReconnect=true&useSSL=false&allowPublicKeyRetrieval=true

Additionally, if you're using a recent version of Rundeck, the MariaDB jdbc driver is the default driver for MySQL and MariaDB backends.

Check this example.
