RedHat Ent 6.5 64bit编译安装hadoop2.4.1
RedHat Ent 6.5 64bit编译安装hadoop2.4.1
感谢原帖：http://blog.csdn.net/w13770269691/article/details/16883663/
step 1.修改yum：（针对redhat ent未注册用户，注册用户直接跳过这一步）
参考：http://blog.csdn.net/zhngjan/article/details/20843465
step 2.下载源码包：http://mirrors.hust.edu.cn/apache/hadoop/common/stable2/
wget http://mirrors.hust.edu.cn/apache/hadoop/common/stable2/hadoop-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/maven/maven-3/3.1.1/binaries/apache-maven-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
[root@cupcs-redhat6 bin]# cd /opt/hadoop-2.4.1-src/hadoop-dist/target/hadoop-2.4.1/bin
[root@cupcs-redhat6 bin]# ./hadoop version
