Win7+Flume1.8.0 + Kafka1.0.0
1.目标
①使用Flume作为Kafka的Producer;
②使用Kafka作为Flume的Sink;
其实以上两点是同一个事情在Flume和Kafka两个立场上的不同描述而已,其实就是同一个事情。
2.运行Kafka
①运行Zookeeper
zkserver
②运行Kafka
这里注意一下是否正常运行了,如果日志报错则将日志文件夹删除后再让其自动重新生成。
.inwindowskafka-server-start.bat .configserver.properties
③创建一个名字为flume的Topic
kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic flume
④打开这个Topic的一个Consumer
kafka-console-consumer.bat --zookeeper localhost:2181 --topic flume
具体可参看《Windows上搭建Kafka运行环境》
3.运行Flume
①创建一个kafka_sink.conf配置文件
# example.conf: A single-node Flume configuration
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
# Describe the sink
a1.sinks.k1.channel = c1
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.topic = flume
a1.sinks.k1.kafka.bootstrap.servers = localhost:9092
a1.sinks.k1.kafka.flumeBatchSize = 20
a1.sinks.k1.kafka.producer.acks = 1
a1.sinks.k1.kafka.producer.linger.ms = 1
a1.sinks.k1.kafka.producer.compression.type = snappy
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
②启动Flume
flume-ng agent --conf ../conf --conf-file ../conf/kafka_sink.conf --name a1 -property flume.root.logger=INFO,console
具体可参看《Windows上搭建Flume运行环境》
4.使用telnet连接并发送数据
①启动另外一个cmd,使用telnet连接到44444端口并发送信息Test Flume and Kafka!
(这里注意一下,在测试过程中,首条数据显示较慢!)
telnet localhost 44444
②在Kafka的Consumer终端显示如下:
以上。
