1）创建Flume Agent配置文件 flume-telnet-logger.conf

2）在配置文件中添加以下内容 参照https://flume.apache.org/FlumeUserGuide

[user@newbie job]$ cat flume-telnet-logger.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 = 6666

# 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
[user@newbie job]$ 

3) Flume开启监听 6666端口，然后执行 telnet localhost 6666，然后输入 hello。我们可以看到消息传了过来。
