1. flume설치파일 다운로드

apache-flume-1.5.2-bin.tar.gz


2. 압축풀기

tar xvfz apache-flume-1.5.2-bin.tar.gz


3. 링크생성

ln -s apache-flume-1.5.2-bin flume


4. 환경변수 수정(vi /home/hadoop/.bashrc)

export FLUME_HOME=/hadoop/flume

export PATH=$PATH:$FLUME_HOME/bin

* 변경사항 반영 : source /home/hadoop/.bashrc


5. Flume Conf

# Each channel's type is defined.

agent.channels.memoryChannel.type = memory


# Other config values specific to each type of channel(sink or source)

# can be defined as well

# In this case, it specifies the capacity of the memory channel

agent.channels.memoryChannel.capacity = 100000
