1.在$FLUME_HOME/conf下新增一个配置文件avro-memory-kafka.conf
注意：Flume版本：flume-ng-1.6.0-cdh5.7.0，其他版本的配置会有所不同。
具体配置参照：http://archive.cloudera.com/cdh5/cdh/5/

avro-memory-kafka.sources = avro-source
avro-memory-kafka.sinks = kafka-sink
avro-memory-kafka.channels = memory-channel

avro-memory-kafka.sources.avro-source.type = avro
avro-memory-kafka.sources.avro-source.bind = 192.168.21.110
avro-memory-kafka.sources.avro-source.port = 44444

avro-memory-kafka.sinks.kafka-sink.type = org.apache.flume.sink.kafka.KafkaSink
avro-memory-kafka.sinks.kafka-sink.brokerList = 192.168.21.110:9092
avro-memory-kafka.sinks.kafka-sink.topic = hello_topic
avro-memory-kafka.sinks.kafka-sink.batchSize = 5
avro-memory-kafka.sinks.kafka-sink.requiredAcks =1

avro-memory-kafka.channels.memory-channel.type = memory

avro-memory-kafka.sources.avro-source.channels = memory-channel
avro-memory-kafka.sinks.kafka-sink.channel = memory-channel

2.重点是配置kafka sink的内容，参考flume-ng-1.6.0-cdh5.7.0官方的文档:

3.先启动avro-memory-kafka监听

flume-ng agent \
--name avro-memory-kafka \
--conf $FLUME_HOME/conf \
--conf-file $FLUME_HOME/conf/avro-memory-kafka.conf \
-Dflume.root.logger=INFO,console

4.然后启动exec-memory-avro.conf

flume-ng agent \
--name exec-memory-avro \
--conf $FLUME_HOME/conf \
--conf-file $FLUME_HOME/conf/exec-memory-avro.conf \
-Dflume.root.logger=INFO,console

5.启动kafka-console-consumer监听kafka的消息变化
kafka-console-consumer.sh --zookeeper 192.168.21.110:2181 --topic hello_topic
