Cloudera Manager安装之Cloudera Manager安装前准备(Ubuntu14.04）（一）

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

https://www.zybuluo.com/ncepuwanghui/note/474966

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。

　参考第一步：

Cloudera Manager安装之Cloudera Manager安装前准备(CentOS6.5）（一）

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。

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）

　我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。

以及，我们还可以设置文件打开数量和用于最大进程数

　　文件打开数量

　　参考

Cloudera Manager安装之Cloudera Manager安装前准备(CentOS6.5）（一）

bigdata@ubuntucmbigdata1:~$ sudo vi /etc/security/limits.conf

* soft nofile 65535
* hard nofile 65535
* soft nproc  32000
* hard nproc  32000

　我这里，仅拿ubuntucmbigdata1来说，其他的ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4是一样的。

　　ubuntu系统的root用户开启

　　参考

Ubuntu14.04安装之后的一些配置

bigdata@ubuntucmbigdata1:~$ sudo -s
root@ubuntucmbigdata1:~# pwd
/home/bigdata
root@ubuntucmbigdata1:~#

MySQL的安装（以下步骤仅仅在ubuntucmbigdata1这台机器上做）

　　注意：Cloudera-Manages-Server 端需要安装 MySQL，Cloudera-Manages-Agent 端可以不装。

　　即，在我这里就是，Cloudera-Manages-Server 是cmbigdata1。同时，我也是喜欢把oozie、hive等这些，都是安装在cmbigdata1这台机器上。

　　Cloudera-Manages-Agent，在我这里就是，cmbigdata2、cmbigdata3和cmbigdata4。

　　参考

安装成功!

　　启动mysql服务

安装MySql成功后，mysql服务会自动启动

root@ubuntucmbigdata1:~# service mysql start
 
或者

root@ubuntucmbigdata1:~# sudo /etc/init.d/mysql start

　　安装mysql JDBC驱动

root@ubuntucmbigdata1:~# apt-get install libmysql-java

设置MySQL的root用户设置密码，这一步，就不需要做了，在CentOS版本里，需要做。在Ubuntu版本，在安装时，就已经设置了。
