到目前位置，Cloudera Manager和CDH最新版本是cdh5.15.1版本，发布日期是2018-8-17，我们可以在本篇博客的截图中可以看到具体信息，我们以当前的最新版本为例，如果你想要安装其他版本，就参考我这个最新版本的流程来安装即可！帮大家踩了不少的坑，我要特别声明一点，本篇博客部署的环境采用的是CentOS7.2.x发行版本。如果你是CentOs6.x版本的话别切记别下载错CDH的版本哟！包括该下载哪个版本我都有详细的介绍~
一.下载CDH和CM
1>.CDH的选择
下载地址：http://archive.cloudera.com/cdh5/parcels/5.15.1/
2>.CM的选择
下载地址：http://archive.cloudera.com/cm5/cm/5/
二.Cloudera Manager 安装（CM安装）
1>.系统环境准备
1.1>.查看当前操作系统环境以及主机映射关系

1.2>.SSH免秘钥登陆（由于你还不确定NameNode具体部署哪一台服务器，因此我们最保险的做法就是各个机器之间两两都配置免秘钥登录，下面我只给出node101.yinzhengjie.org.cn的配置方法！）
