1：去官网下载 flume 1.5 网址是：flume.apache.org
2: 解压对应的tar 包
3：进去flume的conf目录 创建一个文件 vi example.conf
#
Define a memory channel called ch1 on agent1
agent1.channels.ch1.type
= memory
#
Define an Avro source called avro-source1 on agent1 and tell it
#
to bind to0.0.0.0:41414.
Connect it to channel ch1.
agent1.sources.avro-source1.channels
= ch1
agent1.sources.avro-source1.type
= avro
agent1.sources.avro-source1.bind
=0.0.0.0
agent1.sources.avro-source1.port
=41414
#
Define a logger sink that simply logs all events it receives
#
and connect it to the other end of the same channel.
agent1.sinks.log-sink1.channel
= ch1
agent1.sinks.log-sink1.type
= logger
#
Finally, now that we've defined all of our components, tell
#
agent1 which ones we want to activate.
agent1.channels
= ch1
agent1.sources
= avro-source1
agent1.sinks
= log-sink1

把内容拷贝进去
mvflume-env.sh.templateflume-env.sh
然后更改flume-env.sh
里面的java_home 变成你自己的
执行命令 --进入bin目录后 如果配置了环境变量 不需要进去bin目录执行次命令否则进入bin执行此命令
flume-ng
agent --conf conf/ -f example.conf -Dflume.root.logger=DEBUG,console -n agent1
--name,-n
<agentname>
是指配置文件中的 agent的名字 我这个里叫 agent1
--conf-file,-f
<file> 这个是指配置文件的目录 和要指定的配置文件
flume-ng
avro-client --conf /usr/local/flume/conf -H localhost -p41414-F
/etc/passwd -Dflume.root.logger=DEBUG,console
会打印出内容
----------------------读取tomcat logs ------------------------------------------------
在配置文件中 新建一个 tomcat.conf 内容如下
agent1.channels.ch1.type = file
agent1.sources.avro-source1.channels = ch1
agent1.sources.avro-source1.type = exec
agent1.sources.avro-source1.bind = 0.0.0.0
agent1.sources.avro-source1.port = 41414
agent1.sources.avro-source1.command = tail -n +0 -F /usr/local/tomcat/logs/catalina.out #linux命令的输出接受
agent1.sinks.log-sink1.channel = ch1
agent1.sinks.log-sink1.type = file_roll #是指输入类型 读取文件时的
agent1.sinks.log-sink1.directory=/var/log/data #这个是指读取tomcat的日志到什么目录下
agent1.channels = ch1
agent1.sources = avro-source1
agent1.sinks = log-sink1a
配置好后，执行命令：flume-ng agent --conf conf --conf-file conf/tomcat.conf --name agent1 -Dflume.root.logger=INFO,console
启动tomcat 进入 cd/var/log/data
就会看到如下图
大功告成！！！
