其实，基本思路跟如下差不多，我就不多详细说了，贴出主要图。
博主，我是直接借鉴下面这位博主，来进行安装的！（灰常感谢他们！）
Ubuntu14.04用apt在线/离线安装CDH5.1.2[Apache Hadoop 2.3.0

ClouderManager官网
https://www.cloudera.com/documentation/manager/5-1-x/Cloudera-Manager-Installation-Guide/cm5ig_mysql.html#id_trn_pps_xm_unique_1
说在前面的话
我的机器是总共4台，分别为ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4。
在ubuntucmbigdata1上执行了
sudo apt-get install cloudera-manager-daemons cloudera-manager-server sudo apt-get install cloudera-manager-daemons cloudera-manager-agent
即，ubuntucmbigdata1是既做server，又做agent。
在ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4上执行了
sudo apt-get install cloudera-manager-daemons cloudera-manager-agent
即，ubuntucmbigdata2、3、和4是只做agent。
在ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上
新建文件sudo vi /etc/apt/sources.list.d/cloudera-manager.list，复制以下内容到cloudera.list里
# Packages for Cloudera Manager, Version 5, on Ubuntu 14.04 x86_64 deb [arch=amd64] http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm trusty-cm5 contrib deb-src http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm trusty-cm5 contrib
并且在在ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上
向apt添加cloudera源公钥，在所有节点执行如下命令：
curl -s http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/archive.key | sudo apt-key add -
然后，再sudo apt-get update
具体在后面我会详细教大家怎么安装。
的确，我也跟这位博主一样，也需要在实验室里部署。以及也是4台机器。（至于原因，大家都懂得，中国高校研究生喜欢4、3、2、1来进行加速比做实验论文）
在实验室安装过社区版的Hadoop，当时用的是普通PC机，安装的过程遇到了好多问题。当解决了大部分的安装问题之后由于实验室的需求，需要安装一个商业发行版的hadoop ，我们就采用的Cloudera 公司发行的版本。首先要说明的是CDH对内存要求比较高，当我们采用原来的4G内存的PC机，只要启动基本内存就满了，并且会拖慢整个集群的运算速度。所以说安装CDH对硬件的要求比较高。安装CDH 有三种安装方式：在线安装、半离线安装、离线安装。在线安装和离线安装我都安装过，虽然在线安装貌似简单但是实际用起来还是没有离线安装方便，我还是建议大家采用离线安装的方式。不过下面都会介绍在线安装的方式和离线安装的方式。希望对别人有所帮助
其它的，ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4。

Ubuntu14.04安装之后的一些配置
参考
ubuntu 下 visudo的使用
在文件末尾（按快捷键，Shift + g）添加bigdata ALL=(ALL) NOPASSWD:ALL
ctrl+o 保存
ctrl+x 退出。
最后，得到如下
我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。
防火墙
参考
hadoop-2.6.0.tar.gz + spark-1.5.2-bin-hadoop2.6.tgz的集群搭建（单节点）（Ubuntu系统）
由此，表明Ubuntu14.04是默认没开启防火墙的。
我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。
相关服务的安装
如果没有安装的话可以使用下面的命令安装一下。
参考
Ubuntu 14.04 安装 Cloudera Manager 5 And CDH 5 (在线安装)
bigdata@ubuntucmbigdata1:~$ sudo apt-get install lrzsz bigdata@ubuntucmbigdata1:~$ sudo apt-get install openssh-server
这个工具要装（你懂得），2个理由：1，可以远程管理系统。2，Cloudera Manages 集群管理需要用该服务。
我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。
ssh 服务配置、vim的安装
参考
Ubuntu14.04安装之后的一些配置
打开sshd_config文件， 在 /etc/ssh 目录下。
# Authentication: LoginGraceTime 120 #PermitRootLogin without-password PermitRootLogin yes StrictModes yes
注释掉 #PermitRootLogin without-password 行。
添加 PermitRootLogin yes 行
修改后，如下：
我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。
修改hosts文件
vi /etc/hosts
在里面添加主机名和IP之间的对应关系
#127.0.1.1 ubuntucmbigdata1 192.168.86.31 ubuntucmbigdata1 192.168.86.32 ubuntucmbigdata2 192.168.86.33 ubuntucmbigdata3 192.168.86.34 ubuntucmbigdata4
我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。
主机名
bigdata@ubuntucmbigdata1:~$ sudo vim /etc/hostname bigdata@ubuntucmbigdata2:~$ sudo vim /etc/hostname
bigdata@ubuntucmbigdata3:~$ sudo vim /etc/hostname
bigdata@ubuntucmbigdata4:~$ sudo vim /etc/hostname
这里肯定是对的。
配置ssh免密码登录 （对于这一步，其实可以不做，因为，在CM时会自动安装，大家可以跳过）

root@ubuntucmbigdata1:~# service mysql start
