flume1.4.0安装及简单使用

Flume是一个分布式、可靠、和高可用的海量日志采集、聚合和传输的系统,flume-ng是flume的新版本的意思，其中“ng”意为new generate(新一代)，目前来说，flume1.4.0是最新的版本。

1.下载安装包

  可以到官网http://www.apache.org/dist/flume/stable/网站下载安装包：apache-flume-1.4.0-bin.tar.gz

 

2.解压安装包

  tar-zxvf apache-flume-1.4.0-bin.tar.gz

 

3.将解压后的文件夹重命名：

   mvapache-flume-1.4.0-bin  flume140

4.设置环境变量

 vi /etc/profile

export FLUME_HOME=/usr/hadoop/flume140

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$FLUME_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:FLUME_HOME/bin:$PATH

source /etc/profile

 

5.构造agent配置文件

  cd flume140/conf

cpflume-conf.properties.template flume-conf.properties

 

6.运行agent

bin/flume-ngagent -n agent -f conf/flume-conf.properties

  日志输出直接打印到控制台，当运行参数带上—conf conf时：

bin/flume-ngagent -n agent -f conf/flume-conf.properties --conf conf

  输出将写入到日志文件中，日志配置信息在conf/log4j.properties中设置

附flume-conf.properties:

# The configuration file needs to define the sources, 
# the channels and the sinks.
# Sources, channels and sinks are defined per agent, 
# in this case called 'agent'

agent.sources = seqGenSrc
agent.channels = memoryChannel
agent.sinks = loggerSink

# For each one of the sources, the type is defined
agent.sources.seqGenSrc.type = seq

# The channel can be defined as follows.
agent.sources.seqGenSrc.channels = memoryChannel

# Each sink's type must be defined
agent.sinks.loggerSink.type = logger

#Specify the channel the sink should use
agent.sinks.loggerSink.channel = memoryChannel

# 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 = 100
