flume日志采集框架使用

flume日志采集框架使用

  本次学习使用的全部过程均不在集群上,均在本机环境,供学习参考

 先决条件:

  • flume-ng-1.6.0-cdh5.8.3.tar  去cloudrea下载flume框架,笔者是用cdh5.8.3的套餐

  flume的使用环境:

  • 采集特定目录到hdfs环境以供分析离线数据
  • 监听特定端口的socket流数据

  本次将以上两种情况的使用加以记录供以后参考

  • 解压 flume-ng-1.6.0-cdh5.8.3.tar
  • mv flume-ng-1.6.0-cdh5.8.3 flume
  • 准备运行配置文件
    //socket流采集 netcat-logger.conf
    从网络端口接收数据,下沉到logger
    
    
    
    采集配置文件,netcat-logger.conf
    
    
    
    # example.conf: A single-node Flume configuration
    
    # Name the components on this agent
    #给那三个组件取个名字
    a1.sources = r1
    a1.sinks = k1
    a1.channels = c1
    
    # Describe/configure the source
    #类型, 从网络端口接收数据,在本机启动, 所以localhost, type=spoolDir采集目录源,目录里有就采
    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
    #下沉的时候是一批一批的, 下沉的时候是一个个eventChannel参数解释:
    #capacity:默认该通道中最大的可以存储的event数量
    #trasactionCapacity:每次最大可以从source中拿到或者送到sink中的event数量
    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
    
    启动命令:
    #告诉flum启动一个agent,指定配置参数, --name:agent的名字,
    $ bin/flume-ng agent --conf conf --conf-file conf/netcat-logger.conf --name a1 -Dflume.root.logger=INFO,console
    
    传入数据:
    $ telnet localhost 44444
    Trying 127.0.0.1...
    Connected to localhost.localdomain (127.0.0.1).
    Escape character is '^]'.
    Hello world! <ENTER>
    OK
    

    //spooldir配置文件实例  spooldir-hdfs.conf

    监视文件夹
    启动命令:  
    bin/flume-ng agent -c ./conf -f ./conf/spooldir-hdfs.conf -n a1 -Dflume.root.logger=INFO,console
    
    测试: 往/Users/willian/Public/flume放文件(mv ././xxxFile /Users/willian/Pulic/flume),但是不要在里面生成文件
    
    
    ##############
    
    
    # Name the components on this agent
    a1.sources = r1
    a1.sinks = k1
    a1.channels = c1
    
    # Describe/configure the source
    #监听目录,spoolDir指定目录, fileHeader要不要给文件夹前坠名
    a1.sources.r1.type = spooldir
    a1.sources.r1.spoolDir = /Users/willian/Public/flume
    a1.sources.r1.fileHeader = true
    
    # 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
    

        可以看到 完成了采集会出现complete后缀

注意事项

  •      不能出现重名的文件,不然会报错
