Flume NG概述:
Flume NG是一个分布式,高可用,可靠的系统,它能将不同的海量数据收集,移动并存储到一个数据存储系统中。轻量,配置简单,适用于各种日志收集,并支持 Failover和负载均衡。其中Agent包含Source,Channel和 Sink,三者组建了一个Agent。三者的职责如下所示:
- Source:用来消费(收集)数据源到Channel组件中
- Channel:中转临时存储,保存所有Source组件信息
- Sink:从Channel中读取,读取成功后会删除Channel中的信息
单节点安装:
- 下载 tar:
- 解压:
tar -zxvf apache-flume-1.7.0-bin.tar.gz
- 设置环境变量:
export FLUME_HOME=/usr/local/flume
export PATH=$PATH:$FLUME_HOME/bin
- 修改flume-env.sh:
export JAVA_HOME=/usr/java/jdk1.7.0_80
- 测试是否安装成功:
- 修改配置文件:
a1.sources = r1 a1.sinks = k1 a1.channels = c1 # Describe/configure the source a1.sources.r1.type = exec a1.sources.r1.channels = c1 a1.sources.r1.command = tail -F /home/sky/flume/log_exec_tail # Describe the sink a1.sinks.k1.type = logger # 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
- 启动Agent:
flume-ng agent -c conf -f /usr/local/flume/conf/exec_tail.conf -n a1 -Dflume.root.logger=INFO,console
- 测试Flume是否可以接受到日志更新:
测试成功!
