 源码包下载：

http://archive.apache.org/dist/flume/1.8.0/

集群环境：

master 192.168.1.99
slave1 192.168.1.100
slave2 192.168.1.101

下载安装包：

# Master
wget http://archive.apache.org/dist/flume/1.8.0/apache-flume-1.8.0-bin.tar.gz -C /usr/local/src
tar -zxvf apache-flume-1.8.0-bin.tar.gz
mv apache-flume-1.8.0-bin /usr/local/flume

Flume配置:

#Netcat

cd /usr/local/flume/conf

vim flume-netcat.conf

# Name the components on this agent
agent.sources = r1
agent.sinks = k1
agent.channels = c1

# Describe/configuration the source
agent.sources.r1.type = netcat
agent.sources.r1.bind = master
agent.sources.r1.port = 44444

#Describe the sink
agent.sinks.k1.type = logger

# Use a channel which buffers events in memory 
agent.channels.c1.type = memory
agent.channels.c1.capacity = 1000
agent.channels.c1.transactionCapacity = 100

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

验证：

服务端：
/usr/local/flume/bin/flume-ng agent -f flume-netcat.conf -n agent -Dflume.root.logger=INFO, console

客户端：
telnet master 44444

结果如图：

启动kafka，创建topic

/usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties > /dev/null &
kafka-topics.sh --create --zookeeper master:2181,slave1:2181,slave2:2181 --replication-factor 1 --partitions 1 --topic kafkatest

启动flume以及测试

服务端
/usr/local/flume/bin/flume-ng agent -f flume-exec-kafka.conf -n agent -Dflume.root.logger=INFO, console

客户端
echo "wangzai" > test.log

启动kafka客户端

/usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper master:2181,slave1:2181,slave2:2181 --topic kafkatest --from-beginning

结果如图：
