背景：系统的数据量越来越大，日志不能再简单的文件的保存，如此日志将会越来越大，也不方便查找与分析，综合考虑下使用了flume来收集日志，收集日志后向kafka传递消息，下面给出具体的配置
# The configuration file needs to define the sources,# the channels and the sinks.# Sources, channels and sinks are defined per agent, ??# in this case called ‘agent‘agent.sources = r1agent.channels = c1agent.sinks = s1# For each one of the sources, the type is definedagent.sources.r1.type = netcatagent.sources.r1.bind = localhostagent.sources.r1.port = 10245agent.sources.r1.charset = UTF-8# The channel can be defined as follows.agent.sources.r1.channels = c1# Each sink‘s type must be definedagent.sinks.s1.type = org.apache.flume.sink.kafka.KafkaSinkagent.sinks.s1.topic = testagent.sinks.s1.brokerList = ｉｐ:9092agent.sinks.s1.requiredAcks = 1agent.sinks.s1.batchSize = 20agent.sinks.s1.channel = c1# Each channel‘s type is defined.agent.channels.c1.type = memory# Other config values specific to each type of channel(sink or source)# can be defined as well# In this case, it specifies the capacity of the memory channelagent.channels.c1.capacity = 100
启动方式：
bin/flume-ng agent --conf conf --conf-file conf/kafka.conf --name agent -Dflume.root.logger=INFO,console
再启动之前一定要先启动kafka，这里可能会有一个错误
Caused by: java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Batch Expired
这个是因为默认情况下kafka是广播的localhost，所以如果不是同一个机器需要修改下配置
advertised.listeners=PLAINTEXT://ｉｐ:9092把默认的localhost替换成ＩＰ地址 重新启动下就可以了．
flume 整合kafka
