flume

# 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

将上述配置存为：example.conf

然后我们就可以启动 Flume 了：

?

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

PS：-Dflume.root.logger=INFO,console 仅为 debug 使用，请勿生产环境生搬硬套，否则大量的日志会返回到终端。。。

-c/--conf 后跟配置目录，-f/--conf-file 后跟具体的配置文件，-n/--name 指定agent的名称

然后我们再开一个 shell 终端窗口，telnet 上配置中侦听的端口，就可以发消息看到效果了：

$ telnet localhost 44444 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. Hello world! <ENTER> OK

Flume 终端窗口此时会打印出如下信息，就表示成功了：
