在每个机器上创建目录

mkdir -p /home/qun/data/flume/logs

mkdir -p /home/qun/data/flume/data

mkdir -p /home/qun/data/flume/checkpoint

下载flume最新的包：

wget 
tar -zxvf apache-flume-1.6.0-bin.tar.gz

在slave3，slave4配置collectors

touch $FLUME_HOME/conf/server.conf

内容如下

a1.sources = r1
a1.channels = c1
a1.sinks = k1
#set channel
a1.channels.c1.type = file
a1.channels.c1.checkpointDir=/home/qun/data/flume/checkpoint

在slave0，slave1，slave2配置agent

touch $FLUME_HOME/conf/client.conf

内容如下

agent1.sinkgroups.g1.processor.priority.k2 = 1
agent1.sinkgroups.g1.processor.maxpenalty = 10000

在slave3，slave4上启动collecters

flume-ng agent -n a1 -c conf -f /home/qun/apache-flume-1.6.0-bin/conf/server.conf -Dflume.root.logger=DEBUG,console

在slave0，slave1，slave2上启动agent

flume-ng agent -n agent1 -c conf -f /home/qun/apache-flume-1.6.0-bin/conf/client.conf -Dflume.root.logger=DEBUG,console

测试功能

echo "hello flume">>/home/qun/data/flume/logs/test.txt

collector slave3 接收到agent的日志：

测试collecters Failover

杀死slave3的flume进程，kill -9 pid

echo "hello flume">>/home/qun/data/flume/logs/test.txt
collector slave4 接收到agent的日志：
