Flume入门二__Flume入门案例

1. 下载并解压Flume

[root@langzi01 ~]# wget http://www.apache.org/dyn/closer.lua/flume/1.8.0/apache-flume-1.8.0-bin.tar.gz
[root@langzi01 ~]# tar -zxvf apache-flume-1.8.0-bin.tar.gz
#重命名
[root@langzi01 ~]# mv apache-flume-1.8.0-bin /usr/soft/flume

2. 修改配置文件

[hadoop@langzi01 conf]$ pwd
#/usr/soft/flume/conf
[hadoop@langzi01 conf]$ cp flume-conf.properties.template flume.conf
[hadoop@langzi01 conf]$ vim flume.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
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

3. 启动flume

[hadoop@langzi01 conf]$ ../bin/flume-ng agent --conf conf --conf-file flume-conf.properties --name a1 -Dflume.root.logger=INFO,console
