-
--ssl-ca: The path name of the Certificate Authority (CA) certificate file.
-
--ssl-cert: The path name of the server public key certificate file. This can be sent to the client and authenticated against the CA certificate that it has. 服务器公钥证书文件的路径名。 这可以发送到客户端，并根据它拥有的CA证书进行身份验证。
-
--ssl-key: The path name of the server private key file.
mysql --ssl-ca=ca.pem \
--ssl-cert=client-cert.pem \
--ssl-key=client-key.pem
-
--ssl-ca: The path name of the Certificate Authority (CA) certificate file. This option, if used, must specify the same certificate used by the server. (--ssl-capath is similar but specifies the path name of a directory of CA certificate files.)
-
--ssl-cert: The path name of the client public key certificate file.
-
--ssl-key: The path name of the client private key file.
