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

yum -y install wgetyum -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：

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

生成公钥密钥对：

[root@nameNode /]# ssh-keygen -t rsa  Generating public/private rsa key pair.  Enter file in which to save the key (/root/.ssh/id_rsa):  Enter passphrase (empty for no passphrase):  Enter same passphrase again:  Your identification has been saved in /root/.ssh/id_rsa.  Your public key has been saved in /root/.ssh/id_rsa.pub.  The key fingerprint is:  98:3c:31:5c:23:21:73:a0:a0:1f:c6:d3:c3:dc:58:32 root@gifer  The key's randomart image is:  +--[ RSA 2048]----+  |.   E.=.o        |  |.o = @ o .       |  |. * * =          |  | o o o =         |  |  .   = S        |  |       .         |  |                 |  |                 |  |                 |  +-----------------+  

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：

cat id_rsa.pub >> authorized_keys

将公钥文件authorized_keys分发到各dataNode节点：

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

验证ssh无密码登录：

[root@nameNode .ssh]# ssh root@dataNode1Last 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

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

解压

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

2.3.6.修改JAVA_HOME

分别在文件hadoop-env.sh和yarn-env.sh中添加JAVA_HOME配置

vi hadoop-env.sh

export JAVA_HOME=/usr/java/jdk1.7.0_65

vi yarn-env.sh

export JAVA_HOME=/usr/java/jdk1.7.0_65

2.4.格式化文件系统

格式化文件系统：

bin/hdfs namenode -format

输出：
