CDH环境搭建

 一、CDH环境搭建目录

--CDH相关包的下载地址：
http://archive.cloudera.com/cm5/cm/5/
http://archive.cloudera.com/cdh5/parcels/latest/

---创建用户
用户：
userdel -r cloudera-scm
groupadd cloudera-scm
useradd -g cloudera-scm cloudera-scm
passwd cloudera-scm

---杀进程
ps -ef | grep cloudera-scm | awk '{ print $2 }' | sudo xargs kill -9
ps -ef | grep mysql | awk '{ print $2 }' | xargs kill -9

ps -ef |grep cloudera-scm |grep -v grep|cut -c 9-15|xargs kill -9
ps -ef |grep mycanal-1.0-SNAPSHOT.jar |grep -v grep| cut -c 9-15 | xargs kill -9

---创建CDH需要目录
mkdir -p /qhapp/cdh/var/data
/qhapp/cdh
