Flume启动通常会报两种错，一种是log4j没有配置，第二种就是缺少各种jar包。SO:
[root@laiym ~]# cp /usr/local/elasticsearch/lib/*/usr/local/flume/lib/
假设有同样的jar包不用覆盖
下述为flume到elasticsearch的一个配置文件。字段使用方法详情大家看官方给出的定义。
#文件名为flume-es.conf
#定义sources,channel和sinks的名称
agent.sources = tail
agent.sinks = elasticsearch
agent.channels = memoryChannel
#配置source的详情
agent.sources.tail.type = exec
agent.sources.tail.command = tail -F /var/log/secure
agent.sources.tail.interceptors=i1 i2 i3
agent.sources.tail.interceptors.i1.type=regex_extractor
agent.sources.tail.interceptors.i1.regex =(\\w+\\s+\\w+\\s+\\d+\\\:\\d+\\\:\\d+)\\s+(\\w+)\\s+(\\w+)
agent.sources.tail.interceptors.i1.serializers = s1 s2s3
agent.sources.tail.interceptors.i1.serializers.s1.name= time
agent.sources.tail.interceptors.i1.serializers.s2.name= hostname
agent.sources.tail.interceptors.i1.serializers.s3.name= service
agent.sources.tail.interceptors.i2.type=org.apache.flume.interceptor.TimestampInterceptor$Builder
agent.sources.tail.interceptors.i3.type=org.apache.flume.interceptor.HostInterceptor$Builder
agent.sources.tail.interceptors.i3.hostHeader = host
#配置channel的详情
agent.channels.memoryChannel.type = memory
agentes.channels.channel1.capacity = 1000000
agentes.channels.channel1.transactionCapacity = 5000
#agentes.channels.channel1.keep-alive = 10
#配置sink的详情
agent.sinks.elasticsearch.type=org.apache.flume.sink.elasticsearch.ElasticSearchSink
agent.sinks.elasticsearch.batchSize=100
agent.sinks.elasticsearch.hostNames=127.0.0.1:9300
agent.sinks.elasticsearch.indexName=linux_secure
agent.sinks.elasticsearch.indexType=message
agent.sinks.elasticsearch.clusterName=elasticsearch
agent.sinks.elasticsearch.serializer=org.apache.flume.sink.elasticsearch.ElasticSearchLogStashEventSerializer
#配置source、sink和channel的详情
agent.sources.tail.channels = memoryChannel
agent.sinks.elasticsearch.channel = memoryChannel
样本日志为linux的secure日志。

启动时打开INFO日志和console日志。查看启动状态。
[root@laiym ~]# cd /usr/local/flume/
[root@laiym flume]# ./bin/flume-ng agent -c ./conf/ -f./conf/flume-es.conf -n agent -Dflume.root.logger=INFO,console
在ES中的数据截图：
在kibana中的数据截图：
ok。完美。。！
