Flume最早是Cloudera提供的日志收集系统，目前是Apache下的一个孵化项目，Flume支持在日志系统中定制各类数据发送方，用于收集数据。

本文记录一下在CentOS 6.7上，安装flume的步骤，为后期日志收集做准备 :)

下载安装包

本文使用flume-1.7.0， 使用wget获取flume安装包。

[root@dev18 flume]# wget http://ftp.wayne.edu/apache/flume/1.7.0/apache-flume-1.7.0-bin.tar.gz

[root@dev18 flume]#

解压缩

使用tar -zvxf apache-flume-1.7.0-bin.tar.gz 解压缩安装包

[root@dev18 flume]# tar -zvxf apache-flume-1.7.0-bin.tar.gz

配置环境变量

使用vim /etc/proflile命令，打开profile文件，

[root@dev18 flume]# vim /etc/proflile

然后添加FLUME_NAME和FLUME_CONF_DIR变量，如

export FLUME_HOME=/srv/flume/flume
export FLUME_CONF_DIR=$FLUME_HOME/conf
PATH=$FLUME_HOME/bin:$PATH
export PATH

执行source /etc/profile命令使变量生效

[root@dev18 flume]# source /etc/profile

验证安装

可以使用flume-ng version命令来查看，flume安装是否成功。

[root@dev18 flume]# flume-ng version
