Hadoop不提供64位編譯好的版本，只能用原始碼自行編譯64位版本。學習一項技術從安裝開始，學習hadoop要從編譯開始。

1.作業系統編譯環境

yum install cmake lzo-devel zlib-devel gcc gcc-c++ autoconf automake libtool ncurses-devel openssl-devel libXtst

2.安裝JDK

下載JDK1.7，注意只能用1.7，否則編譯會出錯
http://www.Oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

tar zxvf jdk-7u75-linux-x64.tar.gz -C /app

export JAVA_HOME=/app/jdk1.7.0_75
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

PATH=$PATH:$JAVA_HOME/bin

3.安裝protobuf

下載protobuf-2.5.0，不能用高版本，否則Hadoop編譯不能通過
wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

tar xvf protobuf-2.5.0.tar.gz
cd protobuf-2.5.0
./configure
make
make install
ldconfig

protoc --version

4.安裝ANT

wget http://mirror.bit.edu.cn/apache/ant/binaries/apache-ant-1.9.4-bin.tar.gz
tar zxvf apache-ant-1.9.4-bin.tar.gz -C /app

vi /etc/profile
export ANT_HOME=/app/apache-ant-1.9.4
PATH=$PATH:$ANT_HOME/bin

5.安裝maven

wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.3.1/binaries/apache-maven-3.3.1-bin.tar.gz

tar zxvf apache-maven-3.3.1-bin.tar.gz -C /app

vi /etc/profile
export MAVEN_HOME=/app/apache-maven-3.3.1
export PATH=$PATH:$MAVEN_HOME/bin

修改配置檔案
vi /app/apache-maven-3.3.1/conf/settings.xml

更改maven資料庫，在<mirrors></mirros>裡新增如下內容：

<mirror>
<id>nexus-osc</id>
<mirrorOf>*</mirrorOf>
<name>Nexusosc</name>
<url>http://maven.oschina.net/content/groups/public/</url>
</mirror>

在<profiles></profiles>內新新增

<profile>
<id>jdk-1.7</id>
<activation>
<jdk>1.7</jdk>
</activation>
<repositories>
<repository>
<id>nexus</id>
<name>local private nexus</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<name>local private nexus</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>

6.安裝findbugs（非必須）
wget http://prdownloads.sourceforge.net/findbugs/findbugs-3.0.1.tar.gz?download
tar zxvf findbugs-3.0.1.tar.gz -C /app

vi /etc/profile
export FINDBUGS_HOME=/app/findbugs-3.0.1
PATH=$PATH:$FINDBUGS_HOME/bin
export PATH

注意：
最終，在/etc/profile中環境變數PATH的設定如下：
PATH=$PATH:$JAVA_HOME/bin:$ANT_HOME/bin:$MAVEN_HOME/bin:$FINDBUGS_HOME/bin
export PATH

在shell下執行，使環境變數生效
. /etc/profile

7.編譯 Hadoop2.6.0

wget http://mirror.bit.edu.cn/apache/hadoop/core/hadoop-2.6.0/hadoop-2.6.0-src.tar.gz
cd hadoop-2.6.0-src
mvn package -DskipTests -Pdist,native -Dtar
