我是靠谱客的博主机灵未来，最近开发中收集的这篇文章主要介绍Flume之——配置多个Sink源（一个Source对应多个Channel和Sink），觉得挺不错的，现在分享给大家，希望可以做个参考。

配置模型如下图：

Flume的配置如下：

myagent.sources = r1
myagent.sinks = k1 k2
myagent.channels = c1 c2
myagent.sources.r1.selector.type = replicating
# 订阅/配置Source源
myagent.sources.r1.type = http
myagent.sources.r1.port = 5140
myagent.sources.r1.handler = org.apache.flume.source.http.JSONHandler

myagent.sources.r1.channels = c1 c2

# 设置Memmory Channel
myagent.sinks.k1.channel = c1
myagent.channels.c1.type = memory
myagent.channels.c1.capacity = 1000
myagent.channels.c1.transactionCapacity = 100

myagent.sinks.k2.channel = c2
myagent.channels.c2.type = memory
myagent.channels.c2.capacity = 1000
myagent.channels.c2.transactionCapacity = 100

#####发送到Kafka####
# 订阅k1 Sink
myagent.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
myagent.sinks.k1.topic = test
myagent.sinks.k1.brokerList = binghe100:9092
myagent.sinks.k1.requiredAcks = 1
myagent.sinks.k1.batchSize = 20

#####发送到HDFS#####
# 订阅Sink
myagent.sinks.k2.type = hdfs
myagent.sinks.k2.hdfs.path = hdfs://binghe100:9000/flume/%Y%m%d
myagent.sinks.k2.hdfs.filePrefix = log_%H_%M
myagent.sinks.k2.hdfs.fileSuffix = .log
myagent.sinks.k2.hdfs.useLocalTimeStamp = true
myagent.sinks.k2.hdfs.writeFormat = Text
myagent.sinks.k2.hdfs.fileType = DataStream
#### 一个小时保存一次
myagent.sinks.k2.hdfs.round = true
myagent.sinks.k2.hdfs.roundValue = 1
myagent.sinks.k2.hdfs.roundUnit = hour
#### 文件达到1M写新文件
myagent.sinks.k2.hdfs.rollInterval = 0
myagent.sinks.k2.hdfs.rollSize=1048576
myagent.sinks.k2.hdfs.rollCount=0

myagent.sinks.k2.hdfs.batchSize = 100
myagent.sinks.k2.hdfs.threadsPoolSize = 10
myagent.sinks.k2.hdfs.idleTimeout = 0
myagent.sinks.k2.hdfs.minBlockReplicas = 1

配置说明如下图所示：

直接监听Nginx日志变化的配置如下:

myagent.sources = s1
myagent.sinks = k1 k2
myagent.channels = c1 c2
myagent.sources.s1.selector.type = replicating
# 订阅/配置Source源
myagent.sources.s1.batchsize=10
myagent.sources.s1.type = exec
myagent.sources.s1.command = tail -F /usr/local/nginx-1.17.2/logs/access.log
 
myagent.sources.s1.channels = c1 c2
 
# 设置Memmory Channel
myagent.sinks.k1.channel = c1
myagent.channels.c1.type = memory
myagent.channels.c1.capacity = 1000
myagent.channels.c1.transactionCapacity = 100
 
myagent.sinks.k2.channel = c2
myagent.channels.c2.type = memory
myagent.channels.c2.capacity = 1000
myagent.channels.c2.transactionCapacity = 100
 
#####发送到Kafka####
# 订阅k1 Sink
myagent.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
myagent.sinks.k1.topic = test
myagent.sinks.k1.brokerList = binghe100:9092
myagent.sinks.k1.requiredAcks = 1
myagent.sinks.k1.batchSize = 20
 
#####发送到HDFS#####
# 订阅Sink
myagent.sinks.k2.type = hdfs
myagent.sinks.k2.hdfs.path = hdfs://binghe100:9000/flume/%Y%m%d
myagent.sinks.k2.hdfs.filePrefix = log_%H_%M
myagent.sinks.k2.hdfs.fileSuffix = .log
myagent.sinks.k2.hdfs.useLocalTimeStamp = true
myagent.sinks.k2.hdfs.writeFormat = Text
myagent.sinks.k2.hdfs.fileType = DataStream
#### 一个小时保存一次
myagent.sinks.k2.hdfs.round = true
myagent.sinks.k2.hdfs.roundValue = 1
myagent.sinks.k2.hdfs.roundUnit = hour
#### 文件达到1M写新文件
myagent.sinks.k2.hdfs.rollInterval = 0
myagent.sinks.k2.hdfs.rollSize=1048576
myagent.sinks.k2.hdfs.rollCount=0
 
myagent.sinks.k2.hdfs.batchSize = 100
myagent.sinks.k2.hdfs.threadsPoolSize = 10
myagent.sinks.k2.hdfs.idleTimeout = 0
myagent.sinks.k2.hdfs.minBlockReplicas = 1

注意：flume中sink到hdfs，文件系统频繁产生文件，文件滚动配置不起作用，可以将minBlockReplicas设置为1。如下设置项：

myagent.sinks.k2.hdfs.minBlockReplicas = 1
