参考官方文档：http://flume.apache.org/FlumeUserGuide.html

数据采集工具。

两个官网小例子：

1. 从网络端口获取数据

在conf/下创建example.conf文件：

# 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 = weekend01
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
~

执行命令： 

bin/flume-ng agent --conf conf --conf-file example.conf --name a1 -Dflume.root.logger=INFO,console

演示效果：

2. 通过指令获取数据

在conf/下创建文件example2.conf文件：

# 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 = exec
a1.sources.r1.command = tail -F /home/hadoop/flume/test.log
a1.sources.r1.channels = c1

# 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

执行命令： 

bin/flume-ng agent --conf conf --conf-file conf/example2.conf --name a1 -Dflume.root.logger=INFO,console

在自己建的flume/写一段shell程序：

while true; do echo you are my girl >> test.log; sleep 1; done

演示效果：
