Flume--Flume安装+nc测试

    tar -zxf flume-ng-1.6.0-cdh5.14.2.tar.gz
    mv apache-flume-1.6.0-cdh5.14.2-bin/ soft/flume160

    #进入conf目录
    cd /opt/soft/flume160/conf
    
    #复制env备份文件，形成正式文件
    cp flume-env.sh.template flume-env.sh
    
    #进入env文件，修改配置信息
    vi flume-env.sh
    ==>（添加信息）
    export JAVA_HOME=/opt/soft//opt/soft/jdk180	//注意核对自己jdk的地址

    #进入bin目录
    cd ../bin
    ./flume-ng version

下载 ncat （模拟输入端的小程序）
    yum install nmap-ncat.x86_64 -y
    
    2.新建配置文件目录，并添加Agent参数（配置信息可以去官网上复制）
    mkdir /opt/flumeconf
    cd /opt/flumeconf/
    vi conf_0804_simple.properties
    ==>
    # example.conf: A single-node Flume configuration
    
    # Name the components on this agent
    a1.sources = r1
    a1.sinks = k1
    a1.channels = c1
    
    # Describe/configure the source
    a1.sources.r1.type = netcat
    a1.sources.r1.bind = 192.168.56.104	//一定要修改成主机ip
    a1.sources.r1.port = 6666	//设置一个数据监控的端口号，注意端口号不能重复，并且不能超过65536
    
    # 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
    
    3.启动flume
    flume-ng agent -n a1 -c conf -f /opt/flumeconf/conf_0804_simple.properties -Dflume.root.logger=INFO,console
    
    4.另起窗口，启动nc
    nc 192.168.56.104 6666
    
    5.随意在nc窗口输入字符，回车，查看flume窗口是否可以监控到数据
