基于Confluent Kafka部署Kafka Connect集群，Kafka Connect集群加载debezium插件

一、下载Confluent Kafka

Confluent Kafka的下载地址：

下载社区免费版本：

在这里插入图片描述

二、配置文件connect-distributed.properties

核心参数如下所示：

  • /data/src/confluent-7.3.3/etc/schema-registry/connect-distributed.properties
bootstrap.servers=realtime-kafka-001:9092,realtime-kafka-003:9092,realtime-kafka-002:9092


group.id=datasight-confluent-test-debezium-cluster-status

key.converter=org.apache.kafka.connect.json.JsonConverter

value.converter=org.apache.kafka.connect.json.JsonConverter

key.converter.schemas.enable=true
value.converter.schemas.enable=true

config.storage.topic=offline_confluent_test_debezium_cluster_connect_configs
offset.storage.topic=offline_confluent_test_debezium_cluster_connect_offsets
status.storage.topic=offline_confluent_test_debezium_cluster_connect_statuses


config.storage.replication.factor=3
offset.storage.replication.factor=3
status.storage.replication.factor=3

offset.storage.partitions=25
status.storage.partitions=5
config.storage.partitions=1

internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=true
internal.value.converter.schemas.enable=true

#rest.host.name=0.0.0.0
#rest.port=8083

#rest.advertised.host.name=0.0.0.0
#rest.advertised.port=8083

plugin.path=/data/service/debezium/connectors2

三、启动脚本connect-distributed

  • /data/src/confluent-7.3.3/bin/connect-distributed

  • connect-distributed的脚本内容如下所示，可以不需要修改

  • 如果需要导出kafka connector的jmx，则需要设置jmx导出端口和jmx导出器，详细的部署方式可以参考博主下面这篇技术博客：

if [ $# -lt 1 ];
then
        echo "USAGE: $0 [-daemon] connect-distributed.properties"
        exit 1
fi

base_dir=$(dirname $0)

###
### Classpath additions for Confluent Platform releases (LSB-style layout)
###
#cd -P deals with symlink from /bin to /usr/bin
java_base_dir=$( cd -P "$base_dir/../share/java" && pwd )

# confluent-common: required by kafka-serde-tools
# kafka-serde-tools (e.g. Avro serializer): bundled with confluent-schema-registry package
for library in "confluent-security/connect" "kafka" "confluent-common" "kafka-serde-tools" "monitoring-interceptors"; do
  dir="$java_base_dir/$library"
  if [ -d "$dir" ]; then
    classpath_prefix="$CLASSPATH:"
    if [ "x$CLASSPATH" = "x" ]; then
      classpath_prefix=""
    fi
    CLASSPATH="$classpath_prefix$dir/*"
  fi
done

if [ "x$KAFKA_LOG4J_OPTS" = "x" ]; then
  LOG4J_CONFIG_DIR_NORMAL_INSTALL="/etc/kafka"
  LOG4J_CONFIG_NORMAL_INSTALL="${LOG4J_CONFIG_DIR_NORMAL_INSTALL}/connect-log4j.properties"
  LOG4J_CONFIG_DIR_ZIP_INSTALL="$base_dir/../etc/kafka"
  LOG4J_CONFIG_ZIP_INSTALL="${LOG4J_CONFIG_DIR_ZIP_INSTALL}/connect-log4j.properties"
  if [ -e "$LOG4J_CONFIG_NORMAL_INSTALL" ]; then # Normal install layout
    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:${LOG4J_CONFIG_NORMAL_INSTALL} -Dlog4j.config.dir=${LOG4J_CONFIG_DIR_NORMAL_INSTALL}"
  elif [ -e "${LOG4J_CONFIG_ZIP_INSTALL}" ]; then # Simple zip file layout
    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:${LOG4J_CONFIG_ZIP_INSTALL} -Dlog4j.config.dir=${LOG4J_CONFIG_DIR_ZIP_INSTALL}"
  else # Fallback to normal default
    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../config/connect-log4j.properties -Dlog4j.config.dir=$base_dir/../config"
  fi
fi
export KAFKA_LOG4J_OPTS

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
  export KAFKA_HEAP_OPTS="-Xms256M -Xmx2G"
fi

EXTRA_ARGS=${EXTRA_ARGS-'-name connectDistributed'}

COMMAND=$1
case $COMMAND in
  -daemon)
    EXTRA_ARGS="-daemon "$EXTRA_ARGS
    shift
    ;;
  *)
    ;;
esac

export CLASSPATH
exec $(dirname $0)/kafka-run-class $EXTRA_ARGS org.apache.kafka.connect.cli.ConnectDistributed "$@"

四、启动Kafka Connect集群

启动命令如下所示：

/data/src/confluent-7.3.3/bin/connect-distributed /data/src/confluent-7.3.3/etc/schema-registry/connect-distributed.properties

正常启动Kafka Connect集群完整输出如下所示：

五、加载debezium插件

  • 下载debezium插件到plugin.path=/data/service/debezium/connectors2设置的目录下
  • 然后重新启动Kafka Connect集群就能够成功加载debezium插件

重启Kafka Connect集群查看debezium插件是否加载成功，如下所示：成功加载到了debezium 插件

[{
    
    
"class":"io.debezium.connector.mysql.MySqlConnector",
"type":"source",
"version":"2.2.1.Final"},

{
    
    "class":"org.apache.kafka.connect.mirror.MirrorCheckpointConnector","type":"source","version":"7.3.3-ce"},

{
    
    "class":"org.apache.kafka.connect.mirror.MirrorHeartbeatConnector","type":"source","version":"7.3.3-ce"},

{
    
    "class":"org.apache.kafka.connect.mirror.MirrorSourceConnector","type":"source","version":"7.3.3-ce"}]

六、总结和延伸

总结：

  • 至此成功部署了具有一个节点的Kafka Connect集群，如果需要更多节点，需要在多台服务器上启动Kafka Connect，从而组成一个多节点的Kafka Connect集群

基于Kafka Connect加载debezium插件的更多的内容可以参考博主以下几篇技术博客或者Debezium 专栏：

延伸：

  • 组成一个Kafka Connect集群后，需要启动多个connector进行Kafka Connect集群稳定性、可靠性测试。
  • 可以进一步部署Kafka Connect集群UI
