Question

我正在尝试为Kafka和debezium做POC。

我已经启动了kafka和zookeeper，并且它们正在工作...现在，当我尝试加载kafka-connect时（我对此很陌生...），我收到此错误，我只是无法理解我的意思做错了。

注意：我已经使用Debezium教程docker映像对所有这些进行了测试，但是我想从远程服务器连接，并且我认为在没有docker的情况下安装所有内容会更容易进行配置

使用以下命令启动连接

./connect-standalone.sh ~/kafka/config/connect-standalone.properties ~/kafka/config/connect-standalone-worker.properties ~/kafka/config/debezium-connector.properties

connect-standalone.properties

bootstrap.servers=localhost:9092
key.converter.schemas.enable=true
value.converter.schemas.enable=true
offset.flush.interval.ms=10000
plugin.path=/home/ubuntu/kafka/plugins

connect-standalone-worker.properties

internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
offset.storage.file.filename=/home/user/offest
value.converter=org.apache.kafka.connect.json.JsonConverter
key.converter=org.apache.kafka.connect.json.JsonConverter

debezium-connector.properties

name=my-connector
connector.class=io.debezium.connector.mongodb.MongoDbConnector
include.schema.changes=false
mongodb.name=mymongo
collection.whitelist=my.collection
tasks.max=1
mongodb.hosts=A.B.C.D:27017

运行连接时，我得到以下信息：

Answer 1

connect-standalone.properties和connect-standalone-worker.properties必须是一个文件。

错误是说connect-standalone-worker.properties没有connector.class的值（之所以不应该是因为它是辅助属性，而不是连接器）

您要运行的命令应类似于

connect-standalone worker.properties connector1.properties [connector2.properties ... ]

MongoDb Debezium-“连接器配置不包含连接器类型”
