Apache kafka Debezium MySQL错误：连接密码为空

我的Debezium连接器具有以下docker-compose.yml配置：

    version: '3.1'

    services:

    db:
        image: mysql
        network_mode: host
        environment:
        MYSQL_ROOT_PASSWORD: 123456
        volumes:
        - ./mysql.cnf:/etc/mysql/conf.d/mysql.cnf
        ports:
        - 3306:3306
        container_name: mydb

    zookeeper:
        image: confluentinc/cp-zookeeper
        network_mode: host
        ports:
        - "2181:2181"
        environment:
        ZOOKEEPER_CLIENT_PORT: 2181
        container_name: myzookeeper

    kafka:
        image: confluentinc/cp-kafka
        network_mode: host
        depends_on:
        - zookeeper
        - db
        ports:
        - "9092:9092"
        environment:
        KAFKA_ZOOKEEPER_CONNECT: localhost:2181

        container_name: mykafka

    connector:
        image: debezium/connect:0.10
        network_mode: host
        ports:
        - "8083:8083"
        environment:
        GROUP_ID: 1

        depends_on:
        - zookeeper
        - db
        - kafka
        container_name: myconnector

当我想要创建连接器时，我收到以下错误：

    curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/ -d '{ "name": "mystore-connector", "config": { "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.hostname": "localhost", "database.port": "3306", "database.user": "morteza", "database.password": "morteza_password", "database.server.id": "223344", "database.server.name": "dbserver1", "database.whitelist": "mystore", "database.history.kafka.bootstrap.servers": "localhost:9092", "database.history.kafka.topic": "dbhistory.mystore" } }'

Debezium连接器显示此错误：

    The connection password is empty   [io.debezium.connector.mysql.MySqlConnector]
    myconnector  | 2019-03-08 09:38:26,755 INFO   ||  Failed testing connection for jdbc:mysql://localhost:3306/?useInformationSchema=true&nullCatalogMeansCurrent=false&useSSL=false&useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=CONVERT_TO_NULL with user 'morteza'   [io.debezium.connector.mysql.MySqlConnector]

正如您所看到的，我已经设置了database.password字段的值，但是我收到了数据库密码的错误。

正如Jiri Pechanec所建议的，我将docker-compose.yml文件中的image:mysql更改为image:mysql:5.7，现在它工作正常

在Debezium 0.9中，当源MySQL数据库中的用户未被授予所需的权限时，可能会出现不允许公钥检索的错误。在Debezium 0.8中，错误是无法连接：通信链路故障

---

我在这里写了一篇关于这一点的文章，因为我遇到了这个问题，错误消息有点不明显：

不允许公钥检索是从create POST返回的错误。中的一些建议可能值得一试。其中一个建议是，这只是一个无效的用户名/密码组合。下面是一个示例，如果对config.Robin有用的话，我甚至在root和pass 123456中也收到了相同的错误。我认为问题在于此消息不允许公钥检索。IIRC在过去使用SSL时，JDBC驱动程序和MySQL驱动程序版本之间存在兼容性问题。例如，请参见@JiriPechanec谢谢。我将mysql版本改为5.7，设置为image:mysql:5.7，效果很好！我想知道为什么它不被使用。我发现debezium 0.9将支持mysql 8。顺便问一下，你能发布你的答案吗，这样其他用户就可以在类似的情况下使用它了？我使用的是camel debezium mysql插件，它使用debezium connectro 1.3.1.Final版本，显然它没有这个属性database.allowPublicKeyRetrieval。
