Hadoop-2.5.1集群安装配置笔记

 

1.环境

 

1.1.虚拟机

 

准备3台虚拟机，安装Centos 64-bit操作系统，采用最小安装。

（本来想多跑几台虚拟机，但本人笔记本电脑内存有限，最多只能同时跑3个虚拟机）

虚拟机一律配置静态IP地址，配置域名解析，各虚拟机时间同步。

 

192.168.17.100 nameNode

192.168.17.101 dataNode1

192.168.17.102 dataNode2

 

 

2.安装

 

2.1.安装前

 

2.1.1.安装wget和ssh

用于下载和ssh登录

 


  1. yum -y install wget  
  2.   
  3. yum -y install openssh*  

 

 

2.1.2.安装JDK、配置环境变量

略...

 

2.1.3.配置ssh公钥密钥自动登录

在hadoop集群环境中，nameNode节点，需要能够ssh无密码登录访问dataNode节点

进入SSH目录：

 


  1. [root@nameNode ~]# cd .ssh  
  2. [root@nameNode .ssh]#   

 

生成公钥密钥对：

 

[plain] view plaincopy在CODE上查看代码片派生到我的代码片
 
  1. [root@nameNode /]# ssh-keygen -t rsa    
  2. Generating public/private rsa key pair.    
  3. Enter file in which to save the key (/root/.ssh/id_rsa):    
  4. Enter passphrase (empty for no passphrase):    
  5. Enter same passphrase again:    
  6. Your identification has been saved in /root/.ssh/id_rsa.    
  7. Your public key has been saved in /root/.ssh/id_rsa.pub.    
  8. The key fingerprint is:    
  9. 98:3c:31:5c:23:21:73:a0:a0:1f:c6:d3:c3:dc:58:32 root@gifer    
  10. The key's randomart image is:    
  11. +--[ RSA 2048]----+    
  12. |.   E.=.o        |    
  13. |.o = @ o .       |    
  14. |. * * =          |    
  15. | o o o =         |    
  16. |  .   = S        |    
  17. |       .         |    
  18. |                 |    
  19. |                 |    
  20. |                 |    
  21. +-----------------+    

 

看到图形输出，表示密钥生成成功，目录下多出两个文件

私钥文件：id_raa
公钥文件：id_rsa.pub

将公钥文件id_rsa.pub内容放到authorized_keys文件中：

 


 
  1. cat id_rsa.pub >> authorized_keys  

 

将公钥文件authorized_keys分发到各dataNode节点：


 
  1. scp authorized_keys  root@dataNode:/root/.ssh/  

验证ssh无密码登录：

 

[plain] view plaincopy在CODE上查看代码片派生到我的代码片
 
  1. [root@nameNode .ssh]# ssh root@dataNode1  
  2. Last login: Sun Sep 21 11:38:05 2014 from 192.168.17.1  
看到以上输出，表示配置成功！如果还提示需要输出密码访问，表示配置失败！

 

2.2.开始安装

下载最新版本hadoop-2.5.1

 


 
  1. wget http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.5.1/hadoop-2.5.1.tar.gz  

 

解压

 


 
  1. tar -zxf hadoop-2.5.1.tar.gz  


 

2.3.配置文件

进入配置文件目录：cd hadoop-2.5.1/etc/hadoop

2.3.1.core-site.xml
