 You can provide, per server, the following:
 
-1. username which have access to database (defaults to 'root')
-2. password (defaults to none)
-3. mysql my.cnf configuration file
-4. mysql socket (optional)
-5. mysql host (ip or hostname)
-6. mysql port (defaults to 3306)
-7. ssl connection parameters
- - key: the path name of the client private key file.
- - cert: the path name of the client public key certificate file.
- - ca: the path name of the Certificate Authority (CA) certificate file. This option, if used, must specify the same certificate used by the server.
- - capath: the path name of the directory that contains trusted SSL CA certificate files.
- - cipher: the list of permitted ciphers for SSL encryption.
