flume入门基础

1. 在flume的conf目录下创建 example.conf，内容如下

# 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
# Flume提供了各种source的实现，包括Avro Source、 Exce Source、 Spooling Directory Source、 NetCat Source、 Syslog Source、 Syslog TCP Source、Syslog UDP Source、 HTTP Source、 HDFS Source， etc
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# Describe the sink
# 包括HDFS sink、 Logger sink、 Avro sink、 File Roll sink、 Null sink、 HBasesink， etc
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
# Flume对于Channel，则提供了Memory Channel、 JDBC Chanel、 File Channel，etc
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. 用cmd进入到flume的bin目录下，运行

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

3、 另起一个cmd窗口：输入

telent 127.0.0.1 44444


进入到可编辑窗口，在窗口里面输入内容即可在flume启动的窗口中看到内容了
