Flume 实战3 从A服务器采集日志到B服务器

将A服务器上的日志采集到B服务器

技术选型：

(1)exec source +memory channel +avro sink

(2) avro source +memory channgel+logger sink 

需要写两个配置文档

写配置文档

A服务器：exec-memory-avro.conf 

exec-memory-avro.sources = exec-source  #a1代表agent名称，r1:数据源的名称
exec-memory-avro.sinks = avro-sink    #k1 sink名称
exec-memory-avro.channels = memory-channel  #c1 channel名称

exec-memory-avro.sources.exec-source.type = exec 
exec-memory-avro.sources.exec-source.command = tail -F /home/hadoop/data/data.log  
exec-memory-avro.sources.exec_source.shell = /bin/sh -c 

exec-memory-avro.sinks.avro-sink.type = logger
exec-memory-avro.sinks.avro-sink.hostname = 192.168.199.150

exec-memory-avro.sinks.avro-sink.port = 44444

exec-memory-avro.channels.memory-channel.type = memory
exec-memory-avro.channels.memory-channel.capacity = 1000
exec-memory-avro.channels.memory-channel.transactionCapacity = 100

exec-memory-avro.sources.exec-source.channels = memory-channel

exec-memory-avro.sinks.avro-sink.channel = memory-channel

B服务器：avro-memory-logger.conf

avro-memory-logger.sources = avro-source  #a1代表agent名称，r1:数据源的名称
avro-memory-logger.sinks = logger-sink    #k1 sink名称
avro-memory-logger.channels = memory-channel  #c1 channel名称

avro-memory-logger.sources.avro-source.type = avro 
avro-memory-logger.sources.avro-source.bind = 192.168.199.150
avro-memory-logger.sources.avro_source.port = 44444

avro-memory-logger.sinks.logger-sink.type = logger

avro-memory-logger.channels.memory-channel.type = memory
avro-memory-logger.channels.memory-channel.capacity = 1000
avro-memory-logger.channels.memory-channel.transactionCapacity = 100

avro-memory-logger.sources.avro-source.channels = memory-channel
avro-memory-logger.sinks.logger-sink.channel = memory-channel

启动Agent

1.主要启动顺序，首先启动B服务器上的agent

flume-ng agent --name avro-memory-logger --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/avro-memory-logger.conf \

-Dflume.root.logger=INFO,console

2.启动A服务器上的agent

flume-ng agent --name exec-memory-avro --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/exec-memory-avro.conf \

-Dflume.root.logger=INFO,console

日志收集过程：

1.机器A上监控一个文件，当我们访问主站时会有用户行为日志记录到ACCESS.LOG中

2.AVRO sink 把新产生的日志输出到对应的AVRO source指定的hostname 和port 上

3.通过AVRO souce对应的agent将我们的日志输出到控制台，后面大家也可以输出到kafak或HDFS上
