启动和配置flume

Agent 是一个 JVM 进程，它以事件（Event）的形式将数据从源头（Source）通过渠道（Channel）送至目标端（Sink）。

Agent 主要有 3 个部分组成，Source、Channel、Sink。

# 目录->kafka
a1.sources = s1
a1.sinks = k1
a1.channels = c1

a1.sources.s1.channels = c1
a1.sinks.k1.channel = k1

a1.sources.s1.type = exec
a1.sources.s1.command = tail -F /home/yu/access.log

a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.topic = flumnTopic
a1.sinks.k1.kafka.bootstrap.servers = master:2181
a1.sinks.k1.kafka.flumeBatchSize = 20
a1.sinks.k1.kafka.produce.ack = 1
a1.sinks.k1.kafka.produce.linger.ms = 1
a1.sinks.k1.kafka.produce.compression.type = snapp

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transcationCapacity = 100

0.依赖 jdk

1.安装flumn

2.配置环境变量

vim /etc/profile.d/flume.sh

FLUMN_HOME=/opt/flumn
PATH=$PATH:FLUMN_HOME/bin

source profile

3.配置flume

cp flume-env.sh.template flume-env.sh

export JAVA_HOME=/opt/jdk1.8.0_191

cp flume-conf.properties.template flume-conf.properties

source 使用 spoolingDirectory（spooldir）(假脱机目录)

channel 使用memory

sink使用kafka

#1.agent a 
a.sources=aSource
a.channels=aChannel
a.sinks=aSink

# 2.连接
a.sources.aSource.channels=aChannel
a.sinks.aSink.channel=aChannel

# 3.source 
#类型 目录文件
a.sources.aSource.type=spooldir
a.sources.aSource.spoolDir=/opt/apache-zookeeper-3.7.0-bin/logs
# 反序列化器
a.sources.aSource.deserializer=LINE
a.sources.aSource.deserializer.maxLineLength=320000
# 文件正则匹配格式
a.sources.aSource.includePattern= zookeeper-root-server-app.out
# 拦截器
a.sources.aSource.interceptors=head_filter
a.sources.aSource.interceptors.head_filter.type=regex_filter
a.sources.aSource.interceptors.head_filter.regex=^user*
a.sources.aSource.interceptors.head_filter.excludeEvents=true

#4.channel
#a.channels.aChannel.type=file
#a.channels.aChannel.checkpointDir=/opt/kb15tmp/checkpoint/a
#a.channels.aChannel.dataDirs=/opt/kb15tmp/checkpoint/data/a
a.channels.aChannel.type=memory
a.channels.aChannel.capacity=100000
a.channels.aChannel.transactionCapacity=10000

#5.sink
a.sinks.aSink.type=org.apache.flume.sink.kafka.KafkaSink
a.sinks.aSink.batchSize=640
a.sinks.aSink.brokerList=app:9092
a.sinks.aSink.topic=topic01

4.启动flume

# --name a  agent的name
bin/flume-ng agent --conf conf/ --name a --conf-file conf/flume-conf.properties
