flume中配置文件：
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
#
# # Describe/configure the source
a1.sources.r1.type = avro
a1.sources.r1.bind = 0.0.0.0
a1.sources.r1.port = 44444
#
# # Describe the sink
a1.sinks.k1.type = logger
#
# # Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
#
# # Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
在bin下启动flume： ./flume-ng agent --conf ../conf/ --conf-file ../conf/fluxtext.conf --name a1 -Dflume.root.logger=INFO,console
log4j.properties的配置文件：
log4j.rootLogger = info,stdout,flume
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern =[%-5p]%d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
log4j.appender.flume = org.apache.flume.clients.log4jappender.Log4jAppender
log4j.appender.flume.Hostname = 服务器ip地址
log4j.appender.flume.Port = 44444
log4j.appender.flume.UnsafeMode = false
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %m%n
最后访问页面即可产生日志数据成功打印在控制台并传回Flume日志服务器中！~~~~~
