Hadoop-2.5.1集羣安裝配置筆記
1.環境
1.1.虛擬機
準備3臺虛擬機，安裝Centos 64-bit操作系統，採用最小安裝。
（本來想多跑幾臺虛擬機，但本人筆記本電腦內存有限，最多隻能同時跑3個虛擬機）
虛擬機一律配置靜態IP地址，配置域名解析，各虛擬機時間同步。
192.168.17.100 nameNode
192.168.17.101 dataNode1
192.168.17.102 dataNode2
2.安裝
2.1.安裝前
2.1.1.安裝wget和ssh
用於下載和ssh登錄
yum -y install wget
yum -y install openssh*
2.1.2.安裝JDK、配置環境變量
略...
2.1.3.配置ssh公鑰密鑰自動登錄
在hadoop集羣環境中，nameNode節點，需要能夠ssh無密碼登錄訪問dataNode節點
進入SSH目錄：
[root@nameNode ~]# cd .ssh
[root@nameNode .ssh]# 生成公鑰密鑰對：
[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 |
| . |
| |
| |
| |
+-----------------+ 看到圖形輸出，表示密鑰生成成功，目錄下多出兩個文件
私鑰文件：id_raa
公鑰文件：id_rsa.pub
將公鑰文件id_rsa.pub內容放到authorized_keys文件中：
cat id_rsa.pub >> authorized_keys將公鑰文件authorized_keys分發到各dataNode節點：
scp authorized_keys root@dataNode:/root/.ssh/驗證ssh無密碼登錄：
[root@nameNode .ssh]# ssh root@dataNode1

分別在文件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_65export JAVA_HOME=/usr/java/jdk1.7.0_652.4.格式化文件系統
