flume入门之一：flume 安装及测试

http://flume.apache.org/

flume下载：http://mirror.bit.edu.cn/apache/flume/1.7.0/apache-flume-1.7.0-bin.tar.gz

flume安装：tar apache-flume-1.7.0-bin.tar.gz

修改conf/flume-conf.properties.template文件名为flume-conf

修改文件内容：

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 =   

# 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 =
a1.channels.c1.transactionCapacity =   

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

启动服务：

flume-ng.cmd agent -conf ../conf -conf-file ../conf/flume_conf.conf -name a1 -property flume.root.logger=INFO,console

输出日志：

再打开一个终端，输入“flume success!”

lz@ubuntu:~$ telnet localhost
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
flume success!
OK

退出telnet:  输入ctrl+]  然后 q

flume将接收到数据，打印日志：
