Flume實戰案例一,從指定網路埠採集資料輸出到控制檯

flume新建任務就是在寫配置檔案
配置example.conf
在conf下新建檔案example.conf
加入
# example.conf: A single-node Flume configuration 需要配置agent a1 source r1 channel k1 sinks c1 然後將source,channel,sinks關聯起來 # 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
5.啟動agent
flume-ng agent --name a1 --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/example.conf -Dflume.root.logger=INFO.console
6.Flume監聽一個埠
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
所以監聽的是本地的44444埠,
新開一個本地視窗telnet localhost 44444 之後輸入資訊之後 flume就可以打印出來資訊了(-Dflume.root.logger配置的是在控制檯輸出資訊)
