一、场景一描述:
线上api接口服务通过log4j往本地磁盘上打印日志,在接口服务器上安装flume,通过exec source收集日志,然后通过avro sink发送到汇总服务器上的flume;汇总服务器上的flume通过avro source接收日志,然后通过file_roll sink写到本地磁盘。
假设:api接口服务器两台 10.153.140.250和10.153.140.251,汇总日志的服务器一台 10.153.137.211
1、api接口服务器上flume配置:
1)在api接口服务器上下载、解压、安装flume:
[html] view plain copy
- cd /usr/local/
- wget http://mirror.bit.edu.cn/apache/flume/1.7.0/apache-flume-1.7.0-bin.tar.gz
- tar -xvzf apache-flume-1.7.9-bin.tar.gz
- vim /etc/profile
- export PS1="[\[email protected]`/sbin/ifconfig eth0|grep ‘inet ‘|awk -F‘[: ]+‘ ‘{print $4}‘` \W]"‘$ ‘
- export FLUME_HOME=/usr/local/apache-flume-1.6.0-bin
- export PATH=$PATH:$FLUME_HOME/bin
2)修改flume-env.sh 配置文件:
cd /usr/local/flume/conf
vim flume-env.sh
里面指定java_home,同时在conf目录添加log4j.properties文件;
3)flume配置文件:
agent1.sources = ngrinder
agent1.channels = mc1
agent1.sinks = avro-sink
agent1.sources.ngrinder.type = exec
agent1.sources.ngrinder.command = tail -F /data/logs/ttbrain/ttbrain-recommend-api.log
agent1.sources.ngrinder.channels = mc1
agent1.channels.mc1.type = memory
agent1.channels.mc1.capacity = 1000
agent1.channels.mc1.keep-alive = 60
agent1.sinks.avro-sink.type = avro
agent1.sinks.avro-sink.channel = mc1
agent1.sinks.avro-sink.hostname = 10.153.137.211
agent1.sinks.avro-sink.port = 4545
注意:这里的sink使用了avro,接口服务器的flume会通过rpc的方式将日志数据发给汇总日志的服务器;
4)启动:
nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/test-tomcat-log.conf -n agent1 >/dev/null 2>&1 &
2、在汇总日志服务器上flume配置:
1)安装、解压、配置flume:
2)flume配置文件:
collector1.sources = AvroIn
collector1.channels = mc1
collector1.sinks = LocalOut
collector1.sources.AvroIn.type = avro
collector1.sources.AvroIn.bind = 10.153.137.211
collector1.sources.AvroIn.port = 4545
collector1.sources.AvroIn.channels = mc1
collector1.channels.mc1.type = memory
collector1.channels.mc1.capacity = 100
collector1.channels.mc1.transactionCapacity = 100
collector1.sinks.LocalOut.type = file_roll
collector1.sinks.LocalOut.sink.directory = /data/tomcat_log_bak
collector1.sinks.LocalOut.sink.rollInterval = 0
collector1.sinks.LocalOut.channel = mc1
说明:
A、这里的source使用的是avro,和api接口的flume进行对接;
B、这里使用file_roll的sink,将日志数据保存到本地磁盘;
注:bind只能写本机ip或者机器名,不能写localhost等。
3)启动:
nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/tomcat_collection.conf -n collector1 -Dflume.root.logger=INFO,console >/dev/null 2>&1 &
这是,我们会发现/data/tomcat_log_bak 目录下会生成从两台接口服务器上收集回来的日志。
二、场景二描述:
线上api接口服务通过log4j往本地磁盘上打印日志,在接口服务器上安装flume,通过exec source收集日志,然后通过avro sink将日志发送到汇总服务器上的flume;在汇总服务器上的flume,通过avro source接收到日志,然后通过hdfs sink备份到hdfs上。
假设有api接口服务器两台 10.153.140.250和10.153.140.251,汇总日志的服务器一台 10.153.137.211
1、api接口服务器上flume配置:
同上;
2、汇总服务器上flume配置:
1)安装、解压flume:
2)flume配置文件:
agent1.channels = ch1
agent1.sources = s1
agent1.sinks = log-sink1
agent1.sources.s1.type = avro
agent1.sources.s1.bind = 10.153.135.113
agent1.sources.s1.port = 41414
agent1.sources.s1.threads = 5
agent1.sources.s1.channels = ch1
agent1.channels.ch1.type = memory
agent1.channels.ch1.capacity = 100000
agent1.channels.ch1.transactionCapacity = 100000
agent1.channels.ch1.keep-alive = 30
agent1.sinks.log-sink1.type = hdfs
agent1.sinks.log-sink1.hdfs.path = hdfs://hadoop-jy-namenode/data/qytt/flume
agent1.sinks.log-sink1.hdfs.writeFormat = Text
agent1.sinks.log-sink1.hdfs.fileType = DataStream
agent1.sinks.log-sink1.hdfs.rollInterval = 0
agent1.sinks.log-sink1.hdfs.rollSize = 60554432
agent1.sinks.log-sink1.hdfs.rollCount = 0
agent1.sinks.log-sink1.hdfs.batchSize = 1000
agent1.sinks.log-sink1.hdfs.txnEventMax = 1000
agent1.sinks.log-sink1.hdfs.callTimeout = 60000
agent1.sinks.log-sink1.hdfs.appendTimeout = 60000
agent1.sinks.log-sink1.channel = ch1
说明:
A、这里的source使用的是avro,和api接口的flume进行对接;
B、这里的sink使用的是hdfs,可以将数据写入到hdfs上,这里需要指定hadoop集群的namenode地址。(hdfs://hadoop-jy-namenode/)
3)启动:
nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/hdfs.conf -n agent1 >/dev/null 2>&1 &
这时,我们会在hdfs的/data/qytt/flume目录下生成从两台接口服务器上收集回来的日志。
假设有api接口服务器两台 10.153.140.250和10.153.140.251,我们可以在接口服务器上部署flume ,将
汇总日志的服务器一台 10.153.137.211
