本篇博客CDH的部署完全通过Cloudera Manager的webUI的安装向导来完成的，关于CM的部署详情请参考：https://www.cnblogs.com/yinzhengjie/p/9495964.html。
一.安装CHD的服务
1>.CM的webUI界面默认的用户名/密码都是小写的admin,我们输入用户名和密码进行登录。操作如下：
2>.同一CM的协议，点击继续
3>.选择CM的免费版本
4>.点击继续
5>.为 CDH 群集安装指定主机
6>.选择CDH本地版本（即我们自己下载好的版本）
7>.CDH的默认存放路径介绍
8>.当CDH安装完毕后，点击继续
9>.等待检查主机完成
10>.我们可以根据下面的提示去相应的服务器做具体的操作，做完操作后点击“重新运行”以验证你是否配置成功！
11>.解决告警信息后，点击完成

12>.自定义需要安装的服务
13>.分配角色
14>.等待审核
15>.集群设置
16>.等待安装完成
17>.完成安装后，点击继续
18>.CDH部署成功界面
19>.进入CDH主界面
二.验证CHD服务是否可用
1>.验证zookeeper是否可以正常使用

2>.查看hdfs目录信息（注意权限，如果你想要往指定目录写数据的话，可以指定ACL）
[root@node101 ~]# hdfs dfs -ls -R /
drwxrwxrwt - hdfs supergroup -- : /tmp
drwxrwxrwt - mapred hadoop -- : /tmp/logs
drwxr-xr-x - hdfs supergroup -- : /user
drwxrwxrwx - mapred hadoop -- : /user/history
drwxrwx--- - mapred hadoop -- : /user/history/done
ls: Permission denied: user=root, access=READ_EXECUTE, inode="/user/history/done":mapred:hadoop:drwxrwx---
drwxrwxrwt - mapred hadoop -- : /user/history/done_intermediate
[root@node101 ~]#
3>.查看hdfs的webUI界面
查看hdfs的界面如下，试试有种似曾相识的感脚？
