一、上传

• 获得apache-flume-1.5.0-bin.tar.gz

• 上传

二、安装

• 解压并重命名

  tar -zxvf apache-flume-1.5.0-bin.tar.gz -C /softWare/
  mv apache-flume-1.5.0-bin/ flume-1.5.0-bin

• 改名

  cd /softWare/flume-1.5.0-bin/conf
  mv flume-env.sh.template flume-env.sh

• 更改配置文件

  • 修改flume-env.sh文件

  vim flume-env.sh
  JAVA_HOME=/softWare/jdk1.7.0_80     

三、启动（bin/flume-ng agent -n a4 -c conf -f conf/a4.conf -Dflume.root.logger=INFO,console）

• 1、上传a4.conf到flume的conf目录下

  mv /a4.conf /softWare/flume-1.5.0-bin/conf/

• 2、上传hadoop-common-2.2.0.jar到flume的lib目录下

  scp /softWare/hadoop-2.2.0/share/hadoop/common/hadoop-common-2.2.0.jar 
  root@192.168.2.107:/softWare/flume-1.5.0-bin/lib/

• 3、上传commons-configuration-1.6.jar到flume的lib目录下

  scp /softWare/hadoop-2.2.0/share/hadoop/common/lib/commons-configuration-1.6.jar 

  root@192.168.2.107:/softWare/flume-1.5.0-bin/lib/

• 4、上传hadoop-auth-2.2.0.jar到flume的lib目录下

  scp /softWare/hadoop-2.2.0/share/hadoop/common/lib/hadoop-auth-2.2.0.jar 
  root@192.168.2.107:/softWare/flume-1.5.0-bin/lib/

• 5、创建a4.conf里a4.sources.r1.spoolDir = /flumelogs指定的/flumelogs目录

  mkdir /logs

• 6、上传core-site.xml到flume的conf目录下

  scp /softWare/hadoop-2.2.0/etc/hadoop/core-site.xml 
  root@192.168.2.107:/softWare/flume-1.5.0-bin/conf

• 7、上传hdfs-site.xml到flume的conf目录下

  scp /softWare/hadoop-2.2.0/etc/hadoop/hdfs-site.xml 
  root@192.168.2.107:/softWare/flume-1.5.0-bin/conf

• 8、上传hadoop-hdfs-2.2.0.jar到flume的lib目录下

  scp /softWare/hadoop-2.2.0/share/hadoop/hdfs/hadoop-hdfs-2.2.0.jar 
  root@192.168.2.107:/softWare/flume-1.5.0-bin/lib/

• 9、启动

  cd /softWare/flume-1.5.0-bin/
  bin/flume-ng agent -n a4 -c conf -f conf/a4.conf -Dflume.root.logger=INFO,console

• 10、将数据放进logs里

  cp /access_2013_05_30.log /logs/

• 11、a4.conf的内容

  #定义agent名， source、channel、sink的名称
  a4.sources = r1
  a4.channels = c1
  a4.sinks = k1
  
  #具体定义source
  a4.sources.r1.type = spooldir
  a4.sources.r1.spoolDir = /logs
  
  #具体定义channel
  a4.channels.c1.type = memory
  a4.channels.c1.capacity = 10000
  a4.channels.c1.transactionCapacity = 100
  
  #定义拦截器，为消息添加时间戳
  a4.sources.r1.interceptors = i1
  a4.sources.r1.interceptors.i1.type = org.apache.flume.interceptor.TimestampInterceptor$Builder
  
  
  #具体定义sink
  a4.sinks.k1.type = hdfs
  a4.sinks.k1.hdfs.path = hdfs://ns1/flume/%Y%m%d
  a4.sinks.k1.hdfs.filePrefix = events-
  a4.sinks.k1.hdfs.fileType = DataStream
  #不按照条数生成文件
  a4.sinks.k1.hdfs.rollCount = 0
  #HDFS上的文件达到128M时生成一个文件
  a4.sinks.k1.hdfs.rollSize = 134217728
  #HDFS上的文件达到60秒生成一个文件
  a4.sinks.k1.hdfs.rollInterval = 60
  
  #组装source、channel、sink
  a4.sources.r1.channels = c1
  a4.sinks.k1.channel = c1

三、使用（tail -F /a.log）

• 1、创建a.log文件并写入内容

  # cd /
  # touch a.log
  # vim a.log
  
  111111111111111111

• 2、执行

  # cd /softWare/flume-1.5.0-bin/
  # tail -F /a.log
  1111111111111111111111
  
  
  # echo "2222222222" >> a.log
  
  1111111111111111111111
  2222222222
