一、source配置
1、netcat的source:bind指定IP,port指定port
# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
2、读文件exec:commd中写命令,如果用tail的话记得用大写的F
# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /opt/module/hive/logs/hive.log
a1.sources.r1.shell = /bin/bash -c
3、读取文件夹source:spooldir source ,tmp记得一定要忽略
# Describe/configure the source
a1.sources.r1.type = spooldir
# 指定文件夹
a1.sources.r1.spoolDir = /opt/module/flume/upload
#指定文件上传后的后缀
a1.sources.r1.fileSuffix = .COMPLETED
a1.sources.r1.fileHeader = true
#忽略所有以.tmp结尾的文件,不上传
a1.sources.r1.ignorePattern = ([^ ]*\.tmp)
4、最常用的source: arvo模式,bind指的是接收的主机,port不是随意的,是看sink给的端口
# Describe/configure the source
a1.sources.r1.type = avro
a1.sources.r1.bind = hadoop102
a1.sources.r1.port = 4141
二、sink配置文件
sink的选择特别多,常用的是hdfs,kafka,hbase,logger,同时还可能是avro,arvo主要是给下一个flume接收
1、hdfs的sink:
# Describe the sink
a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = hdfs://hadoop102:9000/flume/%Y%m%d/%H
#上传文件的前缀
a1.sinks.k1.hdfs.filePrefix = logs-
#是否按照时间滚动文件夹
a1.sinks.k1.hdfs.round = true
#多少时间单位创建一个新的文件夹
a1.sinks.k1.hdfs.roundValue = 1
#重新定义时间单位
a1.sinks.k1.hdfs.roundUnit = hour
#是否使用本地时间戳
a1.sinks.k1.hdfs.useLocalTimeStamp = true
#积攒多少个Event才flush到HDFS一次
a1.sinks.k1.hdfs.batchSize = 1000
#设置文件类型,可支持压缩
a1.sinks.k1.hdfs.fileType = DataStream
#多久生成一个新的文件 单位是秒
a1.sinks.k1.hdfs.rollInterval = 600
#设置每个文件的滚动大小 128M
a1.sinks.k1.hdfs.rollSize = 134217700
#文件的滚动与Event数量无关
a1.sinks.k1.hdfs.rollCount = 0
#最小冗余数
a1.sinks.k1.hdfs.minBlockReplicas = 1
2、arvo sink:hostname是IP指的是发送给谁,port指的是监听端口可以任意写
a1.sinks.k2.type = avro
a1.sinks.k2.hostname = hadoop102
a1.sinks.k2.port = 4142
3、logger sink: 如果是像在控制台看打印,要在命令加,-Dflume.root.logger=INFO,console
# Describe the sink
a1.sinks.k1.type = logger
4、hbase待续
三、channel的配置
channel主要分为memory channel和file channel,如果是要求速度和不追求数据的完整性用,memory channel, 一般也都用它
1、memory channel:1000指的是队列的容量,100指的是sink取数据的时候最大值
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
2、file channel:见文档
四、channel 和source,sink的绑定
1、单个source和单个sink
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
2、单个source和多个
# Bind the source and sink to the channel
a1.sources.r1.channels = c1 c2
a1.sinks.k1.channel = c1
