mysql cdc配置问题应该怎么办？

各位好：         我通过mysql cdc链接mysql(mariadb)一直不成功。网上也搜不到有效的解决方法。

        用pyflink调试就一直运行也没数据也不报错。用flink sql就报java.net.ConnectException: Connection refused。

        用slave可以远程连接mysql，也执行了 grant replication client, replication slave on . to 'slave'@'%' identified by 'slave';

sql和mysql的配置信息在下方，期盼大佬解答

flink sql如下：

CREATE TEMPORARY TABLE xin_test (

>           id INT,

>           name STRING

>         ) WITH (

>             'connector' = 'mysql-cdc',

>             'hostname' = '..*.203',

>             'port' = '3306',

>             'username' = 'slave',

>             'password' = 'slave',

>             'database-name' = 'test',

>             'table-name' = 'test',

>             'server-id' = '10001',

>             'server-time-zone' = 'Asia/Shanghai'

>         )

> ;

Flink SQL> select * from xin_test;

[ERROR] Could not execute SQL statement. Reason:

java.net.ConnectException: Connection refused
