flume 整合kafka

1，安装并成功能运行flume

2，安装并成功能运行kafka

3，安装并成功能运行zookeeper

4，开始整合flume收集的数据，写入kafka

a,修改flume的配置文加：

vim  flume_kafka.conf

agent1.sources = r1

agent1.sinks = k1

agent1.channels = c1

# Describe/configure the source

agent1.sources.r1.type = exec

agent1.sources.r1.command=tail -f /opt/logs/usercenter.log

# Use a channel which buffers events in memory

agent1.channels.c1.type = memory

agent1.channels.c1.capacity = 1000

agent1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel

agent1.sources.r1.channels = c1

agent1.sinks.k1.channel = c1

# # Describe the sink  这部分就是输入到kafka的写法

##############################################

agent1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink

agent1.sinks.k1.topic = test

agent1.sinks.k1.brokerList = hadoop1:9092,hadoop2:9092,hadoop3:9092

agent1.sinks.k1.requiredAcks = 1

agent1.sinks.k1.batchSize = 20

b,下载第三方插件

下载flume-kafka-plus:https://github.com/beyondj2ee/flumeng-kafka-plugin

把lib目录下的

和package下的

都放到flume的lib目录

如果，报错，请看这个文档

修改原有的flume-conf文件

在插件包里有一个flume-conf.properties，把这个文件放到flume的conf文件夹里

然后修改以下内容

producer.sources.s.type = exec
 producer.sources.s.command = tail -f -n+1  /opt/logs/test.log
 producer.sources.s.channels = c
……
producer.sinks.r.custom.topic.name=test
……
consumer.sources.s.custom.topic.name=test

c:启动服务

启动zookeeper集群

zkServer.sh start

zkServer.sh start

zkServer.sh start

还需要创建一个新的地址

zookeeper/bin/zkCli.sh

create /kafka  test

启动kafka broker 集群

bin/kafka-server-start.sh config/server.properties

bin/kafka-server-start.sh config/server.properties

bin/kafka-server-start.sh config/server.properties

创建kafka topic

bin/kafka-topics.sh --create --zookeeper localhost:2181/kafka --replication-factor 1 --partitions 1 --topic test

启动kafka consumer

bin/kafka-console-consumer.sh --zookeeper localhost:2181/kafka --topic test --from-beginning

启动flume

bin/flume-ng agent --conf conf --conf-file conf/flume_kafka.properties --name producer -Dflume.root.logger=INFO,console

测试

echo "this is a test" >> /opt/logs/test.log

此时只要能在consumer里现“this is a test”就表示成功
