快速学习-Flume 对接 Kafka

第 6 章 Flume 对接 Kafka

1）配置 flume(flume-kafka.conf)

# define
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F -c +0 /opt/module/data/flume.log
a1.sources.r1.shell = /bin/bash -c
# sink
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.bootstrap.servers = 
hadoop102:9092,hadoop103:9092,hadoop104:9092
a1.sinks.k1.kafka.topic = first
a1.sinks.k1.kafka.flumeBatchSize = 20
a1.sinks.k1.kafka.producer.acks = 1
a1.sinks.k1.kafka.producer.linger.ms = 1
# channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
# bind
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

2） 启动 kafkaIDEA 消费者
3） 进入 flume 根目录下，启动 flume

$ bin/flume-ng agent -c conf/ -n a1 -f jobs/flume-kafka.conf

4） 向 /opt/module/data/flume.log 里追加数据，查看 kafka 消费者消费情况

$ echo hello >> /opt/module/data/flume.log
