Apache Hadoop生态系统安装包下载地址：http://archive.apache.org/dist/
软件安装目录：~/app
jdk: jdk-7u45-linux-x64.rpm hadoop: hadoop-2.5.1-src.tar.gz maven: apache-maven-3.0.5-bin.zip protobuf: protobuf-2.5.0.tar.gz
1、下载hadoop
wget http://archive.apache.org/dist/hadoop/core/stable/hadoop-2.5.1-src.tar.gz tar -zxvf hadoop-2.5.1-src.tar.gz
在解压后的hadoop根目录下有个BUILDING.txt文件，可以看到编译hadoop的环境要求
Requirements: * Unix System * JDK 1.6+ * Maven 3.0 or later * Findbugs 1.3.9 (if running findbugs) * ProtocolBuffer 2.5.0 * CMake 2.6 or newer (if compiling native code) * Zlib devel (if compiling native code) * openssl devel ( if compiling native hadoop-pipes ) * Internet connection for first build (to fetch all Maven and Hadoop dependencies)
2、安装jdk
sudo yum install jdk-7u45-linux-x64.rpm
查看jdk安装位置：
which java /usr/java/jdk1.7.0_45/bin/java
添加jdk到环境变量(~/.bash_profile)：
export JAVA_HOME=/usr/java/jdk1.7.0_45 export PATH=.:$JAVA_HOME/bin:$PATH
验证：
java -version
java version "1.7.0_45" Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
3、安装maven
wget http://apache.fayea.com/apache-mirror/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.zip unzip apache-maven-3.0.5-bin.zip
添加maven到环境变量(~/.bash_profile):
export MAVEN_HOME=/home/hadoop/app/apache-maven-3.0.5 export PATH=.:$MAVEN_HOME/bin:$PATH
验证：
mvn -version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 05:51:28-0800) Maven home: /home/hadoop/app/apache-maven-3.0.5 Java version: 1.7.0_45, vendor: Oracle Corporation Java home: /usr/java/jdk1.7.0_45/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、安装protobuf
protobuf的官方地址貌似上不了，自行下载protobuf安装包；为了编译安装protobuf，需要先gcc/gcc-c++/make
sudo yum install gcc sudo yum install gcc-c++ sudo yum install make
tar -zvxf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./configure --prefix=/usr/local/protoc/ sudo make sudo make install
添加protobuf到环境变量(~/.bash_profile):
export PATH=.:/usr/local/protoc/bin:$PATH
验证：
protoc --version libprotoc 2.5.0
5、安装其他依赖
sudo yum install cmake sudo yum install openssl-devel sudo yum install ncurses-devel
6、编译hadoop源代码
cd ~/app/hadoop-2.5.1-src mvn package -DskipTests -Pdist,native

编译后的代码在hadoop-2.5.1-src/hadoop-dist/target/hadoop-2.5.1下，以后要搭建hadoop环境直接使用hadoop-2.5.1文件夹部署即可。
