flume安装及简单的配置

• 首先我们要准备flume的安装包，这里我们安装的flume版本是apache-flume-1.6.0-bin.tar.gz

  flume的运行环境是基于java环境下运行的，所以在安装flume之前我么你要先安装java环境

• 安装好java环境并测试成功后，我们开始安装flume
  1、flume安装包放在/usr/flume,先解压安装包,解压了就可以了，不用再去安装啦

  tar -zxvf apache-flume-1.6.0-bin.tar.gz 

  
  2、配置环境变量

  vi /etc/profile
  
  在最后添加以下内容：
  export FLUME_HOME=/usr/flume/apache-flume-1.6.0-bin
  export FLUME_CONF_DIR=$FLUME_HOME/conf
  export PATH=$PATH:$FLUME_HOME/bin

  

  source /etc/profile#使配置生效
  echo $PATH #查看环境变量

  
  3、配置flume的基本配置(引入java环境)
  (1):修改usr/flume/apache-flume-1.6.0-bin/conf/flume-env.sh.template

  # If this file is placed at FLUME_CONF_DIR/flume-env.sh, it will be sourced
  
  
  # during Flume startup.
  
  
  # Enviroment variables can be set here.
  
  export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.91-0.b14.el7_2.x86_64/jre
  
  # Give Flume more memory and pre-allocate, enable remote monitoring via JMX
  
  export JAVA_OPTS="-Xms100m -Xmx2000m -Dcom.sun.management.jmxremote"
  
  # Note that the Flume conf directory is always included in the classpath.
  
  
  #FLUME_CLASSPATH=""
  

  (2)新建一个test.conf配置flume的source，实现简单的小例子,放在conf文件夹里面
  a1.sources = r1
  a1.sinks = k1
  a1.channels = c1
  # Describe/configure the source
  a1.sources.r1.type = netcat
  a1.sources.r1.bind = localhost
  a1.sources.r1.port = 44444
  # 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flume：/usr/flume/apache-flume-1.6.0-bin/bin/flume-ng agent --conf /usr/flume/apache-flume-1.6.0-bin/conf/ --conf-file /usr/flume/apache-flume-1.6.0-bin/conf/test.conf --name a1 -Dflume.root.logger=INFO,console

  如图表示flume启动成功
  
  (3)再打开一个终端：

  telnet localhost 44444

  
  如果提示无法识别telnet

   yum install telnet

  发送
  
  结果
  

总结：到这里flume的安装配置，以及最简单的实例已经介绍完毕，这只是flume众多手机source中的一种，下面会一一举例。（flume集中简单的实例）
