1.安裝虛擬機Centos環境
安裝鏡像下載地址：http://vault.centos.org/6.4/isos/x86_64/
下載上圖標出的兩個。安裝時選第一個就可以了。
安裝過程略。可以參見如下文檔安裝。
http://pan.baidu.com/s/1dDowIjv
我的環境是：
[root@hadoop1 target]# uname -a
Linux hadoop1 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
2.安裝jdk----jdk-7u67-linux-x64.tar.gz
由於Hadoop是用Java開發的，故編譯時要用到jdk.
此次安裝的版本是jdk-7u67-linux-x64.tar.gz
jdk安裝文件可以到如下網盤地址去下載：
http://pan.baidu.com/s/1jGqUupw
安裝方法：
第一步：tar -zxvf jdk-7u67-linux-x64.tar.gz
第二步：mv jdk1.7.0_67 jdk1.7
第三步：vi /etc/profile
添加如下內容：
export JAVA_HOME=/usr/local/jdk1.7
export PATH=.:$PATH:$JAVA_HOME/bin
保存後：source /etc/profile
第四步：java -version
[root@hadoop1 soft]# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)
3.安裝maven---apache-maven-3.0.5-bin.tar.gz
由於Hadoop2是用Maven來管理項目的，故要編譯源碼，需要用Maven
maven下載地址：http://pan.baidu.com/s/1bnlcZeR
當然也可以到官網去下載
安裝步驟：
解壓並改名
tar -zxvf apache-maven-3.0.5-bin.tar.gz
mv apache-maven-3.0.5 maven
vi /etc/profile
添加如下內容
export MAVEN_HOME=/usr/local/maven
export PATH=.:$PATH:$MAVEN_HOME
source /etc/profile
驗證：mvn -version
[root@hadoop1 soft]# mvn -version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21:51:28+0800)
Maven home: /usr/local/maven
Java version: 1.7.0_67, vendor: Oracle Corporation
Java home: /usr/local/jdk1.7/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-358.el6.x86_64", arch: "amd64", family: "unix"
4.安裝findbugs -- findbugs-3.0.0.tar.gz
findbugs是用來生成文檔的，如果不需要生成編譯文檔，此步驟可以忽略。
安裝文件下載地址：
http://pan.baidu.com/s/1pJr0dR1
安裝步驟：
tar -zxvf findbugs-3.0.0.tar.gz
mv findbugs-3.0.0 findbugs
配置環境變量：
vi /etc/profile
export FINDBUGS_HOME=/usr/local/findbugs
export PATH=.:$PATH:$FINDBUGS_HOME/bin
source /etc/profile
驗證：findbugs -version
[root@hadoop1 soft]# findbugs -version
3.0.0
5.安裝protoc
由於Hadoop是使用protocol buffer通信的，故要安裝protoc.
官網：https://code.google.com/p/protobuf/downloads/list
我的下載地址：http://pan.baidu.com/s/1zshyA
爲了安裝protoc，需要安裝以下幾個工具：
前提：需要centos虛擬機可以連網。
yum install gcc
yum intall gcc-c++
yum install maketar -zxvf protobuf-2.5.0.tar.gz
cd protobuf-2.5.0
./configure --prefix=/usr/local/protoc
make
make install
以上執行步驟只要不出錯就可以了
編譯文件位於：/usr/local/protoc
配置環境變量：
export PROTOC_HOME=/usr/local/protoc
export PATH=.:$PATH:$PROTOC_HOME
source /etc/profile
驗證：
[root@hadoop1 soft]# protoc --version
libprotoc 2.5.0
6.安裝其它依賴包
yum install cmake
yum install openssl-devel
yum install ncurses-devel從官網下載Hadoop2.2源碼
http://apache.fayea.com/apache-mirror/hadoop/common/hadoop-2.2.0/
或者從下面的網盤下載：
http://pan.baidu.com/s/1dD6DC2l
安裝步驟：
tar -zxvf hadoop-2.2.0-src.tar.gz
cd hadoop-2.2.0-src
修復bug一枚
在hadoop-2.2.0-src目錄下的如下文件：
/usr/local/hadoop-2.2.0-src/hadoop-common-project/hadoop-auth中的文件pom.xml
在第55行加入如下配置：
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>mvn package -DskipTests -Pdist,native,docs
如果沒有安裝生成文檔的findbugs，則去掉後邊的docs
由於maven需要上網去下載需要的jar包，幫該命令會執行時間較長。
如果最後控制檯輸出如下信息：
