RedHat Ent 6.5 64bit编译安装hadoop2.4.1

ljhk

step 2.下载源码包：http://mirrors.hust.edu.cn/apache/hadoop/common/stable2/

wget http://mirrors.hust.edu.cn/apach ... op-2.4.1-src.tar.gz

  step 3.准备maven作为编译hadoop的工具

    a.下载编译好的maven包：

wget http://mirror.bit.edu.cn/apache/ ... en-3.1.1-bin.tar.gz
tar -zxvf apache-maven-3.1.1-bin.tar.gz -C /opt/

    b.配置maven的环境变量，在/etc/profile文件结尾中添加如下代码

export MAVEN_HOME=/opt/apache-maven-3.1.1
export PATH=$PATH:${MAVEN_HOME}/bin

    c.执行如下命令使配置文件生效

source /etc/profile

    d.测试maven

mvn -version

   e.由于maven国外服务器可能连不上，先给maven配置一下国内镜像

    在maven目录下，conf/settings.xml,在<mirrors></mirros>里添加如下内容（注意不要添加到注释里面了）


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



在maven目录下，conf/settings.xml,在<profiles></profiles>添加如下内容（注意不要添加到注释里面了）


<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>  



  step 4.hadoop2.4.1编译需要protoc2.5.0的支持，所以还要安装下载protoc2.5.0

    官方网址：https://code.google.com/p/protobuf/downloads/list

    百度网盘网址：http://pan.baidu.com/s/1pJlZubT

    a.对protoc进行编译安装前先要装几个依赖包:gcc,gcc-c++,make 如果已经安装的可以忽略

yum install gcc  
yum intall gcc-c++  
yum install make

   b.配置protoc

tar -xvf protobuf-2.5.0.tar.bz2  
cd protobuf-2.5.0  
./configure --prefix=/opt/protoc/  
make && make install
yum install gcc

    红色字体是自定义的protoc安装目录，完成上面的命令后，再配置protoc环境变量，同样在/etc/profile尾部加入：

export PATH=/opt/protoc/bin:$PATH

  step 5.，还不要着急开始编译安装，不然又是各种错误,需要安装cmake,openssl-devel,ncurses-devel依赖

yum install cmake  
yum install openssl-devel  
yum install ncurses-devel  

  step 6. 解压并编译hadoop源码(一定要进入到源码解压的位置再执行mvn编译)

tar -zxvf hadoop-2.4.1-src.tar.gz -C /opt/
cd /opt/hadoop-2.4.1-src
mvn package -Pdist,native -DskipTests -Dtar

编译耗时比较长，耐心等待，成功后结果类似于：

编译后的路径在:hadoop-2.4.1-src/hadoop-dist/target/hadoop-2.4.1

进入hadoop-2.4.1目录，测试安装是否成功


[iyunv@cupcs-redhat6 bin]# cd /opt/hadoop-2.4.1-src/hadoop-dist/target/hadoop-2.4.1/bin
