前言：
参考官网，测试运行。
https://flume.apache.org/FlumeUserGuide.html#exec-source
内容：监控一个文件实时采集新增的数据输出到控制台
步骤
（1）配置文件
- 在
/conf 下 新建配置 exec-memory-logger.conf
- 配置内容
a1.sources.r1.command = tail -F /home/donaldy/Documents/data.log 指 监听的文件
# example.conf: A single-node Flume configuration
# 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 /home/donaldy/Documents/data.log
a1.sources.r1.shell = /bin/sh -c
# 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
（2）运行
./flume-ng agent -n a1 -c $FLUME_HOME/conf -f /data/soft/flume/apache-flume-1.8.0-bin/conf/exec-memory-logger.conf -Dflume.root.logger=INFO,console
（3）测试
向被监听文件data.log，输入信息
