CM+CDH安装遇到的问题

1、实在是在安装CDH的时候无法安装成功的话，只有重新启动了，下面给大家分享一个神器，按照这个脚本应该差不多就能卸载干净，然后重新安装，写一个脚本，内容如下，救命的神器呀：

#!/bin/bash
sudo /usr/share/cmf/uninstall-cloudera-manager.sh
sudo service cloudera-scm-server stop
sudo service cloudera-scm-server-db stop

sudo service cloudera-scm-agent stop
sudo yum remove cloudera-manager-agent

sudo yum remove cloudera-manager-server
sudo yum remove cloudera-manager-server-db-2
