需求二：監控一個檔案實時採集新增的資料輸出到控制檯

agent選型：exec source + memory channel +logger sink

1）配置檔案

#新建data檔案
cd /kkb/
mkdir data
#新建日誌檔案
/kkb/data
touch data.log

在/conf 下 新建配置 exec-memory-logger.conf
配置內容
a1.sources.r1.command = tail -F /kkb/data/data.log 指 監聽的檔案

# 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 /kkb/data/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)執行：

flume-ng agent -n a1 -c $FLUME_HOME/conf -f /kkb/install/apache-flume-1.7.0-bin/conf/exec-menory.logger.conf -Dflume.root.logger=INFO,console

 (3)測試：

cd /kkb/data/
echo hello >> data.log
echo nihao >> data.log

 成功！！
