CentOS 64位上编译 Hadoop 2.6.0

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

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

 tar zxvf apache-ant-1.9.4-bin.tar.gz -C /app

vim /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

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

修改配置文件
vi /usr/local/apache-maven-3.0.5/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

vim /etc/profile

export FINDBUGS_HOME=/app/findbugs-3.0.1

PATH=$PATH:$FINDBUGS_HOME/bin

export PATH

7.编译 Hadoop2.6.0

cd hadoop-2.6.0-src
mvn package -DskipTests -Pdist,native -Dtar
