flume通过avro对接（汇总数据）

使用场景：

把多台服务器(flume generator)上面的日志汇总到一台或者几台服务器上面（flume collector），然后对接到kafka或者HDFS上

 

Flume Collector服务端

vim flume-server.properties

# agent1 name
a1.channels = c1
a1.sources = r1
a1.sinks = k1

#set channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# other node, slave to master
a1.sources.r1.type = avro
a1.sources.r1.bind = master
a1.sources.r1.port = 52020

# set sink to logger
a1.sinks.k1.type = logger
      

a1.sources.r1.channels = c1
a1.sinks.k1.channel=c1

启动：

## Master
/usr/local/flume/bin/flume-ng agent –f flume-server.properties –name a1

 

Flume Generator客户端

vim flume-client.properties

# a1 name
a1.channels = c1
a1.sources = r1
a1.sinks = k1

#set channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

a1.sources.r1.channels = c1
a1.sources.r1.type = exec
a1.sources.r1.command = tail -f /root/test.log

# set sink1
#a1.sinks.k1.type = logger
a1.sinks.k1.channel = c1
a1.sinks.k1.type = avro
a1.sinks.k1.hostname = master
a1.sinks.k1.port = 52020

a1.sources.r1.channels = c1
a1.sinks.k1.channel=c1

启动：

分别在slave1和slave2服务器上面启动

/usr/local/flume/bin/flume-ng agent –f flume-client.properties –name a1

 

启动之后，在slave1和slave2服务器上面分别执行以下操作：

#slave1
echo "wangzai slave1" > /root/test.log

#slave2
echo "wangzai slave2" > /root/test.log

 

结果：

Master:
