flume的部署及简单测试

来源:互联网 发布:易视直播网络电视下载 编辑:程序博客网 时间:2024/05/20 21:22

Flume 的一些核心概念:

组件功能Agent使用JVM 运行Flume。每台机器运行一个agent,但是可以在一个agent中包含多个sources和sinks。Client生产数据,运行在一个独立的线程。Source从Client收集数据,传递给Channel。Sink从Channel收集数据,运行在一个独立线程。Channel连接 sources 和 sinks ,这个有点像一个队列。Events可以是日志记录、 avro 对象等。

配置flume

第一步:

下载最新的flume-ng

http://flume.apache.org/download.html

第二步:

配置conf
创建:flume-source-conf.properties
source:

#Describe  source
source.sources.src1.type = exec    //类型
source.sources.src1.command = tail  -n +0 -F /home/hduser/logs/debug.log //监控的日志文件


#Describe channel      //配置channel
source.channels.ch1.type = file
source.channels.ch1.checkpointDir = tmp/channels/ch1/checkpoint
source.channels.ch1.dataDirs = tmp/channels/ch1/data


#Describe sink     //配置sink
source.sinks.sink2.type = file_roll
source.sinks.sink2.sink.directory=store
source.sinks.sink2.sink.serializer = text
source.sinks.sink2.sink.serializer.appendNewline = true
source.sinks.sink2.sink.rollInterval = 43200


//配置变量:

vim ~/.bash_profile
#export FLUME_HOME
export FLUME_HOME=/home/hduser/softsare/flume-1.6.0
export PATH=$PATH:$FLUME_HOME/sbin


. ~/.bash_profile   //一定执行者一步让变量生效


启动命令:flume strart source

停止命令:flume stop source


//到此简单的flume配置完成,,可以用下面的日志生成程序产生日志。
