安装使用flume

1 首先去官网下载 http://flume.apache.org/download.html。这里选择bin的形式。
2 解压 就可以了
3 修改配置文件 在根目录创建个example.conf，内容是：

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /usr/logs/log.10
a1.sources.r1.channels = c1

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = file
a1.channels.c1.checkpointDir = /usr/logs/data
a1.channels.c1.dataDirs = /usr/logs/check

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

4 启动flume：bin/flume-ng agent --conf conf --conf-file example.conf --name a1 -Dflume.root.logger=INFO,console

这样控制台上就会不断打印出/usr/logs/log.10这个文件增加的日志。/usr/logs/check也会保留/usr/logs/log.10的内容。
