一、前置准备:
Linux命令基础
Scala、Python其中一门
Hadoop、Spark、Flume、Kafka、Hbase基础知识
 
二、分布式日志收集框架Flume
业务现状分析:服务器、web服务产生的大量日志,怎么使用,怎么将大量日志导入到集群
1、shell脚本批量,再传到Hdfs:实效性不高,容错率低,网络/磁盘IO,监控
2、Flume:
Flume:关键在于写配置文件
1)配置 agent
2)配置 Source
3)配置 Channel
4)配置 Sink
1-netcat-mem-logger.conf :监听端口数据

#example for source=netcat, channel=memory, sink=logger
# Name the components on this agent
a1.sources = r1
a1.channels = c1
a1.sinks = k1

# configure for sources
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# configure for channels
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# configure for sinks
a1.sinks.k1.type = logger

# configure 
a1.sinks.k1.channel = c1
a1.sources.r1.channels = c1
启动 flume-ng agent \
-n a1 \
-c conf -f ./1-netcat-mem-logger.conf \
-Dflume.root.logger=INFO,console
 
exec-mem-logger.conf :监控文件
# Name the components on this agent
a1.sources = r1
a1.channels = c1
a1.sinks = k1

# configure for sources
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /opt/datas/flume_data/exec_tail.log

# configure for channels
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# configure for sinks
a1.sinks.k1.type = logger
a1.sinks.k1.channel = c1
a1.sources.r1.channels = c1
flume-ng agent \
-n a1 \
-c conf -f ./4-exec-mem-logger.conf \
-Dflume.root.logger=INFO,console

日志收集过程:
1. 日志服务器,启动agent,exec-source, memory-channel,avro-sink(数据服务器), 将收集到的日志数据,写到数据服务器
2. 数据服务器,启动agent,avro-aource,memory-channel,logger-sink/kafka-sink

conf1:exec-mem-avro.conf

# Name the components on this agent
a1.sources = exec-source
a1.channels = memory-channel
a1.sinks = avro-sink

# configure for sources
a1.sources.exec-source.type = exec
a1.sources.exec-source.command = tail -F /opt/datas/log-collect-system/log_server.log

# configure for channels
a1.channels.memory-channel.type = memory
a1.channels.memory-channel.capacity = 1000
a1.channels.memory-channel.transactionCapacity = 100

# configure for sinks
a1.sinks.avro-sink.type = avro
a1.sinks.avro-sink.hostname = localhost
a1.sinks.avro-sink.port = 44444

# configure 
a1.sinks.avro-sink.channel = memory-channel
a1.sources.exec-source.channels = memory-channel
conf2:avro-mem-logger.conf

# Name the components on this agent
a1.sources = avro-source
a1.channels = memory-channel
a1.sinks = logger-sink

# configure for sources
a1.sources.avro-source.type = avro
a1.sources.avro-source.bind = localhost
a1.sources.avro-source.port = 44444

# configure for channels
a1.channels.memory-channel.type = memory
a1.channels.memory-channel.capacity = 1000
a1.channels.memory-channel.transactionCapacity = 100

# configure for sinks
a1.sinks.logger-sink.type = logger

# configure 
a1.sinks.logger-sink.channel = memory-channel
a1.sources.avro-source.channels = memory-channel
(非常重要!!!)启动顺序:先启动exec-mem-avro.conf再启动exec-mem-avro.conf
