flume（三）、简单demo

1、nc输入源、memory作管道、logger作sink

• 配置flume-conf.properties

### demo 1
# a1 source
a1.sources = r1
a1.channels = c1
a1.sinks = k1
# a1
a1.sources.r1.type = netcat
a1.sources.r1.channels = c1
a1.sources.r1.bind = 0.0.0.0
a1.sources.r1.port = 4141
# a1 sink
a1.sinks.k1.type = logger
# a1 channel
a1.channels.c1.type = memory
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

• 启动脚本
  ./flume-ng agent -c ../conf -f ../conf/flume-conf.properties -n a1 -Dflume.root.logger=INFO,console

• 测试
  新建1个窗口，nc localhost 4141 然后输入内容，在flume启动的那个窗口就会看到日志输出
