3. 使用 netcat 数据源测试 Flume
cd /usr/local/flume
sudo vim ./conf/example.conf
# 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 = 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
/usr/local/flume/bin/flume-ng agent --conf ./conf --conf-file ./conf/example.conf --name a1 -Dflume.root.logger=INFO,console
启动flume agent出现如下:
再打开一个终端,输入命令
telnet localhost 44444
在第二个终端输入英文或字符 ,回车。在第一个终端会有显示
