postgresql - 使用 debezium 链接 postgresql 11 无法获取数据库测试的编码

问题描述

我使用debezium cdc connect pg，我构建了docker使用的pg 11，pg运行良好。当我在 kafka 连接器中使用 debezium 时，它报告：</p>

无法获取数据库测试的编码

卷曲是：

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST http://localhost:8083/connectors/ -d '{
    "name": "debezium",
    "config": {
        "name": "debezium",
        "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
        "tasks.max": "1",
        "database.hostname": "localhost",
        "database.port": "5432",
        "database.dbname": "test",
        "database.user": "pg",
        "database.password": "135790",
        "database.server.name": "ls",
        "table.whitelist": "public.test",
        "plugin.name": "pgoutput"
    }
}'

卡夫卡例外是：

解决方案

在我看来，名为的数据库test要么不存在，要么用户不可见pg。
