Fume安装配置 在flume的conf下新建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
