1、获取源码
从apache.fayea.com下获取mathout的的tar包：
wget http://apache.fayea.com/mahout/0.12.2/apache-mahout-distribution-0.12.2.tar.gz
2、解压
tar -zxvf apache-mahout-distribution-0.12.2.tar.gz
3、重命名 mv apache-mahout-distribution-0.12.2.tar.gz mahout
4、编辑pom.xml

<?xml version="1.0" encoding="UTF-8"?>

4.执行编译命令;mvn rpm:rpm；
5、rpm包在target/rpm/mathout/RPMS/noarch下
