1 、 阅读编译文档
（1）准备一个 hadoop 源码包，我选择的 hadoop 版本是：hadoop-2.6.5-src.tar.gz，在hadoop-2.6.5 的源码包的根目录下有一个文档叫做 BUILDING.txt，这其中说明了编译
hadoop 所需要的一些编译环境相关的东西。不同的 hadoop 版本的要求都不一样。对应的版本参照 BUILDING.txt
请仔细阅读：
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), must be 3.0 or newer on Mac
* 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）对应以上需求，我们准备好所要求版本的这些软件
1. 准备一台 Unix 类型操作系统，在这里我们选用的是 CentOS-6.7，初次编译要求必须
联网，切记
以下这些东西都是需要的，详细安装在下面，这里只介绍我准备这些软件所选择的版本
2. 安装 openssl-devel
3. 安装 gcc
4. 安装 gcc-c++
5. JDK：jdk-7u80-linux-x64.tar.gz
6. Maven：apache-maven-3.3.3-bin.tar.gz
7. Ant：apache-ant-1.9.4-bin.tar.gz
8. FindBugs：findbugs-3.0.0.tar.gz
9. Cmake：cmake-2.8.12.2.tar.gz
10. Protobuf：protobuf-2.5.0.tar.gz
11. Snappy：snappy-1.1.1.tar.gz2 、 准备编译环境
安装以下软件：
yum -y install svn
yum -y install autoconf automake libtool cmake
yum -y install ncurses-devel
yum -y install openssl-devel
3 、 安装 gcc
先使用命令检测一下看 gcc 是否已经安装过了
gcc -v
gcc version 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)
如果最后一行出现如上的 gcc 版本信息日志，表示已经安装成功过了。
不然使用命令安装：
yum install gcc
4 、 安装 gcc-c++
直接使用命令安装：yum install gcc-c++
5 、 安装 make
make -version
yum install -y make
6 、 安装 maven （必须）
（1） 解压
tar -zxvf /root/soft/apache-maven-3.3.3-bin.tar.gz -C /root/apps/
（2）修改配置文件（如果需要更改默认的 maven 仓库路径的话）
/root/apps/apache-maven-3.3.3/conf
2. 修改配置文件 settings.xml
在配置文件的中部找到 localRepository 这个标签，它本来是注释了的，并且有一个默认仓库路径，我们最好自己设置一个，
所以我自己加了一个，我的路径是：<localRepository>/root/mavenrepo/</localRepository>
3. 配置环境变量
export M2_HOME=/root/apps/apache-maven-3.3.3
export PATH=$PATH:$M2_HOME/bin
4. 检测是否成功
source /etc/profile
mvn -version
7 、 安装 jdk （必须）
1. 解压
tar -zxvf /root/soft/jdk-7u80-linux-x64.tar.gz -C /root/apps/
2. 配置环境变量
export JAVA_HOME=/root/apps/jdk1.7.0_80
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:/root/apps/jdk1.7.0_80/lib/dt.jar:/root/apps/jdk1.7.0_80/lib/tools.jar
3. 检测是否安装
source /etc/profile
java -version
8 、 安装 ant （重要）
1. 解压
tar -zxvf /root/soft/apache-ant-1.9.4-bin.tar.gz -C /root/apps/
2. 配置环境变量
export ANT_HOME=/root/apps/apache-ant-1.9.4
export PATH=$PATH:$ANT_HOME/bin
3. 检测是否安装成功
source /etc/profile
ant -version
9 、 安装 findbugs （可选 ，最好装 ）
1. 解压
tar -zxvf /root/soft/findbugs-3.0.0.tar.gz -C /root/apps/
2. 配置环境变量
export FINDBUGS_HOME=/root/apps/findbugs-3.0.0
export PATH=$PATH:$FINDBUGS_HOME/bin
3. 检测是否安装成功
findbugs -version
10 、 安装 cmake （重要）
1. 解压
tar -zxvf /root/soft/cmake-2.8.12.2.tar.gz -C /root/apps/
2. 安装
首先进入到根目录：
cd /root/apps/cmake-2.8.12.2/
然后依次执行以下命令：
./bootstrap
gmake & gmake install
3. 检测是否安装成功
cmake -version
11 、 安装 protobuf （重要）
1. 解压
tar -zxvf /root/soft/protobuf-2.5.0.tar.gz -C /root/apps/
2. 安装
首先进入到根目录：
cd /root/apps/protobuf-2.5.0/
然后依次执行以下命令：
./configure --prefix=/root/apps/protobuf （表示安装到这个目录）
make
make check
make install
3. 配置环境变量
export PROTOBUF_HOME=/root/apps/protobuf
export PATH=$PATH:$PROTOBUF_HOME/bin
注意：PROTOBUF_HOME 就是我们在执行 configure 命令的时候指定的目录
4. 检测是否安装成功
protoc --version
12 、 安装 Snappy
1. 使用 root 用户安装 Snappy：
tar -zxvf /root/soft/snappy-1.1.1.tar.gz -C /root/apps/
2. 编译安装：
cd snappy-1.1.1/
./configure
make
make install
3. 查看 snappy 库文件
ls -lh /usr/local/lib |grep snappy
13 、 编译 hadoop
1. 解压 hadoop 源码包
tar -zxvf /root/soft/hadoop-2.6.5-src.tar.gz -C /root/apps/
2. 在编译之前防止 java.lang.OutOfMemoryError: Java heap space 堆栈问题,在 centos 系
export MAVEN_OPTS="-Xms256m -Xmx512m"
3. 进入到源码包根目录下
cd /root/apps/hadoop-2.6.5-src
4. 执行命令编译
Create binary distribution with native code and with documentation:
mvn package -Pdist,native,docs -DskipTests –Dtar
如果中途编译失败，并且不要文档的话，请使用这个命令：
mvn clean package -Pdist,native -DskipTests -Dtar -Dsnappy.lib=/usr/local/lib -Dbundle.snappy -Drequire.openssl
tar 和 dist包放到 hadoop-dist 目录下，
native 和 docs包到该.tar.gz 文件中，skipTests
5. 静静等待编译……. 第一次编译预估一个小时左右。
6. 编译成功了的话，最后的日志信息：
