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 = 5858  
  
# 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

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 5858  
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：
