大数据系列教程_分布式日志收集flume
10、分布式日志收集flume./flume-ng agent --conf /home/hadoop/flume140cdh501/conf --conf-file /home/hadoop/flume140cdh501/conf/exec1 --name a1 -Dflume.root.logger=DEBUG,console备注：当hdfs做了HA之后，需要将hadoop的hdfs-site.xml放在flume的conf目录下，hdfs配置为联邦前缀
1、spool配置
agent1表示代理名称
agent1.sources=source1
agent1.sinks=sink1
agent1.channels=channel1
#配置source1
agent1.sources.source1.type=spooldir
agent1.sources.source1.spoolDir=/home/hadoop/flume150cdh512/yth
agent1.sources.source1.channels=channel1
agent1.sources.source1.fileHeader = false
#配置sink1
agent1.sinks.sink1.type=hdfs
agent1.sinks.sink1.hdfs.path=hdfs://hadoopCluster/yth
agent1.sinks.sink1.hdfs.fileType=DataStream
agent1.sinks.sink1.hdfs.writeFormat=TEXT
agent1.sinks.sink1.hdfs.rollInterval=4
agent1.sinks.sink1.channel=channel1
#配置channel1
agent1.channels.channel1.type=file
agent1.channels.channel1.checkpointDir=/home/hadoop/flume150cdh512/yth_tmp123
agent1.channels.channel1.dataDirs=/home/hadoop/flume150cdh512/yth_tmp
1、 exec配置
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.channels = c1
a1.sources.r1.command = tail -F /home/hadoop/flume140cdh501/log.log
#配置sink1
a1.sinks.k1.type=hdfs
a1.sinks.k1.hdfs.path=hdfs://hadoopCluster/exx
a1.sinks.k1.hdfs.fileType=DataStream
a1.sinks.k1.hdfs.writeFormat=TEXT
a1.sinks.k1.hdfs.rollInterval=4
a1.sinks.k1.channel=channel1
a1.sinks.k1.channel=c1
# Use a channel which buffers events in memory
a1.channels.c1.type = file
a1.channels.c1.checkpointDir=/home/hadoop/flume140cdh501/yth_tmp123
a1.channels.c1.dataDirs=/home/hadoop/flume140cdh501/yth_tmp
2、 Kafka配置
3、 a1.sources = r1
4、 a1.sinks = k1
5、 a1.channels = c1
6、 # Describe/configure the source
7、 a1.sources.r1.type = exec
8、 a1.sources.r1.channels = c1
9、 a1.sources.r1.command = tail -F /home/hadoop/flume140cdh501/log.log
10、#配置sink1
11、
12、
13、
14、a1.sinks.k1.type = org.apache.flume.plugins.KafkaSink
15、a1.sinks.k1.metadata.broker.list=node6:9092,node7:9093,node8:9094
16、a1.sinks.k1.partition.key=0
17、a1.sinks.k1.partitioner.class=org.apache.flume.plugins.SinglePartition
18、a1.sinks.k1.serializer.class=kafka.serializer.StringEncoder
19、a1.sinks.k1.request.required.acks=-1
20、#a1.sinks.k1.max.message.size=10000
21、#a1.sinks.k1.producer.type=sync
22、#a1.sinks.k1.custom.encoding=UTF-8
23、a1.sinks.k1.custom.topic.name=mytopic
24、
25、
26、
27、a1.sinks.k1.channel=c1
28、# Use a channel which buffers events in memory
29、a1.channels.c1.type = memory
30、a1.channels.c1.capacity = 1000
