flume文件下沉 kafka相关命令

1.flume配置文件kfk.conf

# Describe/configure the sourcea1.sources.r1.type = execa1.sources.r1.command = tail -F /home/hadoop/tmp/test.txt# Describe the sinka1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSinka1.sinks.k1.topic = mytopica1.sinks.k1.brokerList = hadoop0:9092a1.sinks.k1.requiredAcks = 1a1.sinks.k1.batchSize = 20a1.sinks.k1.channel = c1# Use a channel which buffers events in memorya1.channels.c1.type = memorya1.channels.c1.capacity = 1000a1.channels.c1.transactionCapacity = 100# Bind the source and sink to the channela1.sources.r1.channels = c1a1.sinks.k1.channel = c1

2.启动zookeeper

3.启动kafka
kafka-server-start.sh ~/bda/kafka/config/server.properties

4.创建topic
create –zookeeper localhost:2181 –replication-factor 1 –partitions 1 –topic test

查看：
bin/kafka-topics.sh –list –zookeeper localhost:2181

5.启动flume
bin/flume-ng agent –conf conf –conf-file conf/kfk.conf –name a1 -Dflume.root.logger=INFO,console

6.消费者消费
bin/kafka-console-consumer.sh –bootstrap-server hadoop0:9092 –topic test –from-beginning
（由于配置的时候配置的是hadoop0，虽然ip地址和localhost一样，但是如果输入localhost会报错）
