一、下载安装包

http://flume.apache.org/download.html

二、解压、修改配置文件

[root@hadoop1 opt]# tar -zxvf apache-flume-1.9.0-bin.tar.gz -C /usr/bigdata/
[root@hadoop1 opt]# cd /usr/bigdata/
[root@hadoop1 bigdata]# mv apache-flume-1.9.0-bin/ flume-1.9.0
[root@hadoop1 flume-1.9.0]# mv conf/flume-env.sh.template conf/flume-env.sh
[root@hadoop1 flume-1.9.0]# vim conf/flume-env.sh
export JAVA_HOME=/usr/java/jdk1.8.0_131

二、测试

2.1 需求

使用Flume监听一个端口, 收集该端口数据, 并打印到控制台。

2.2 安装netcat工具

[root@hadoop1 flume-1.9.0]# yum install -y nc

2.3 创建配置文件

在flume目录下创建job文件夹并进入job文件夹, 在job文件夹下创建Flume Agent配置文件flume-netcat-logger.conf。

[root@hadoop1 flume-1.9.0]# mkdir job
[root@hadoop1 flume-1.9.0]# cd job
[root@hadoop1 job]# vim flume-netcat-logger.conf

# 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 = 10000
a1.channels.c1.transactionCapacity = 1000

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

2.4 先开启flume监听端口

[root@hadoop1 flume-1.9.0]# bin/flume-ng agent -c conf/ -n a1 -f job/flume-netcat-logger.conf -Dflume.root.logger=INFO,console

2.5 使用netcat工具向本机的44444端口发送内容

[root@hadoop1 ~]# nc localhost 44444
1112222333444
OK
flume
OK
hallo
OK

2.6 在Flume监听页面观察接收数据情况
