本文详细介绍如何使用Flume进行日志数据采集，包括通过tail命令监控Nginx日志并实时传输至HDFS，以及利用Netcat源接收数据并通过logger接收器记录日志。深入解析配置文件tail-hdfs.conf和netcat-logger.conf，提供具体启动命令。

亲测有效

tail-hdfs.conf

用tail命令获取数据，下沉到hdfs
启动命令：
bin/flume-ng agent -c conf -f conf/tail-hdfs.conf -n a1
########

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /var/log/nginx/access.log
a1.sources.r1.channels = c1

# Describe the sink
a1.sinks.k1.type = hdfs
a1.sinks.k1.channel = c1
a1.sinks.k1.hdfs.path = /weblog/%y-%m-%d/%H%M/
a1.sinks.k1.hdfs.filePrefix = events-
a1.sinks.k1.hdfs.round = true
a1.sinks.k1.hdfs.roundValue = 10
a1.sinks.k1.hdfs.roundUnit = minute
a1.sinks.k1.hdfs.rollInterval = 3
a1.sinks.k1.hdfs.rollSize = 20
a1.sinks.k1.hdfs.rollCount = 5
a1.sinks.k1.hdfs.batchSize = 1
a1.sinks.k1.hdfs.useLocalTimeStamp = true
#生成的文件类型，默认是Sequencefile，可用DataStream，则为普通文本
a1.sinks.k1.hdfs.fileType = DataStream



# 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

使用agent 监听 telnet anget-hostname port （telnet localhost 44444）在conf目录下编写文件netcat-logger.conf

#agent中各组件的名字
a1.sources = r1
a1.sinks = k1
a1.channels = c1
 
# 描述和配置source组件：r1
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
 
# 描述和配置sink组件：k1
a1.sinks.k1.type = logger
 
# 描述和配置channel组件，此处使用是内存缓存的方式
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
 
# 描述和配置source  channel   sink之间的连接关系
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

启动flume开始采集

bin/flume-ng agent -c conf -f conf/netcat-logger.conf -n a1
