7.2 kafka 和 Flume 集成

目标:

flume 收集 /opt/module/datas/flume.log 文件的内容, 然后 sink 到 kafka, 我们开启 kafka 消费者消费数据

步骤1: 配置 flume

创建配置文件:flume-kafka.conf 内容如下:

# define
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /opt/module/datas/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 = hadoop201:9092,hadoop201:9092,hadoop203:9092
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

开启 idea 消费者

启动 Flume

flume-ng agent -c conf -f job/flume-kafka.conf -n a1

向/opt/module/datas/flume.log 写入数据

写入数据:

kafka和flume集成在了一起了
呵呵
哈哈哈
嗯嗯
