flume实时读取文件到kafka

背景：需要实时读取log日志文件中的记录到kafka

1.zookeeper服务需要开启，查看zookeeper的状态，（zookeeper的安装及启动过程可查看 https://www.cnblogs.com/cstark/p/14573395.html）

[root@master kafka_2.11-0.11]# /opt/soft/zookeeper-3.4.13/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/soft/zookeeper-3.4.13/bin/../conf/zoo.cfg
Mode: follower

2.kafka服务需要开启

/opt/soft/kafka_2.11-0.11/bin/kafka-server-start.sh /opt/soft/kafka_2.11-0.11/config/server.properties

3.启动flume 的配置文件

 启动flume：bin/flume-ng agent --conf conf --conf-file ./conf/job/file_to_hdfs.conf --name a1

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

# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /opt/data/mall/16/mall.log  # 需要监控的文件

# Describe the sink
#a1.sinks.k1.type = logger
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.topic = test
a1.sinks.k1.brokerList = master:9092
a1.sinks.k1.requiredAcks = 1
a1.sinks.k1.batchSize = 20

# 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

4.查看kafka对应的topic里面数据是否有同步过来

/opt/soft/kafka_2.11-0.11/bin/kafka-console-consumer.sh --bootstrap-server master:9092 --from-beginning --topic test
