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 wget 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：
[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@dataNode1 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
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

2.3.5.slaves
dataNode1 dataNode2
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_65vi 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：
