前言：

根据官方的例子，测试运行下。

内容：即从指定网络端口采集数据输出到控制台

步骤

---

（1）配置文件

1. 在 /conf 下创建 exmaple.conf
2. 拷贝，配置exmaple.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

（2）启动Flume

./flume-ng agent -n a1 -c $FLUME_HOME/conf -f /data/soft/flume/apache-flume-1.8.0-bin/conf/exmaple.conf -Dflume.root.logger=INFO,console

这里 $FLUME_HOME 就是 /data/soft/flume/apache-flume-1.8.0-bin

（3）使用telnet 进行测试

另起个终端，输入：
telnet localhost 44444
