1）创建netcat-logger.conf
# 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 = localhost a1.sources.r1.port = 44444 # 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
2）启动 agent 去采集数据
bin/flume-ng agent -c conf -f conf/netcat-logger.conf -n a1 -Dflume.root.logger=INFO,console -c conf 指定 flume 自身的配置文件所在目录 -f conf/netcat-logger.con 指定我们所描述的采集方案 -n a1 指定我们这个 agent 的名字
3）测试
先要往 agent 采集监听的端口上发送数据，让 agent 有数据可采。 随便在一个能跟 agent 节点联网的机器上： telnet anget-hostname port （telnet localhost 44444）
