Hadoop不提供64位编译好的版本，只能用源码自行编译64位版本。学习一项技术从安装开始，学习hadoop要从编译开始。
1.操作系统编译环境
yum install cmake lzo-devel zlib-devel gcc gcc-c autoconf automake libtool ncurses-devel openssl-devel libXtst
2.安装JDK
下载JDK1.7，注意只能用1.7，否则编译会出错 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:$JAVA_HOME/bin
3.安装protobuf
下载protobuf-2.5.0，不能用高版本，否则Hadoop编译不能通过 wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz
tar xvf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./configure make make install ldconfig
protoc --version
4.安装ANT
wget http://mirror.bit.edu.cn/apache/ant/binaries/apache-ant-1.9.4-bin.tar.gz tar zxvf apache-ant-1.9.4-bin.tar.gz -C /app
vi /etc/profile export ANT_HOME=/app/apache-ant-1.9.4 PATH=$PATH:$ANT_HOME/bin
5.安装maven
wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.3.1/binaries/apache-maven-3.3.1-bin.tar.gz
tar zxvf apache-maven-3.3.1-bin.tar.gz -C /app
vi /etc/profile export MAVEN_HOME=/app/apache-maven-3.3.1 export PATH=$PATH:$MAVEN_HOME/bin
修改配置文件 vi /app/apache-maven-3.3.1/conf/settings.xml
更改maven资料库，在<mirrors></mirros>里添加如下内容：
<mirror> <id>nexus-osc</id> <mirrorOf>*</mirrorOf> <name>Nexusosc</name> <url>http://maven.oschina.net/content/groups/public/</url> </mirror>
在<profiles></profiles>内新添加
<profile> <id>jdk-1.7</id> <activation> <jdk>1.7</jdk> </activation> <repositories> <repository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile>
6.安装findbugs（非必须） wget http://prdownloads.sourceforge.net/findbugs/findbugs-3.0.1.tar.gz?download tar zxvf findbugs-3.0.1.tar.gz -C /app
vi /etc/profile export FINDBUGS_HOME=/app/findbugs-3.0.1 PATH=$PATH:$FINDBUGS_HOME/bin export PATH
注意： 最终，在/etc/profile中环境变量PATH的设置如下： PATH=$PATH:$JAVA_HOME/bin:$ANT_HOME/bin:$MAVEN_HOME/bin:$FINDBUGS_HOME/bin export PATH
在shell下执行，使环境变量生效 . /etc/profile
7.编译 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

编译成功后会打包，放在hadoop-dist/target # ls antrun dist-tar-stitching.sh hadoop-2.6.0.tar.gz hadoop-dist-2.6.0-javadoc.jar maven-archiver dist-layout-stitching.sh hadoop-2.6.0 hadoop-dist-2.6.0.jar javadoc-bundle-options test-dir
