一、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
