Hadoop编译步骤：

1.解压Hadoop源码包

[root@hadoop000 ~]# mkdir -p /opt/sourcecode[root@hadoop000 ~]# mkdir -p /opt/software[root@hadoop000 sourcecode]# cd /opt/sourcecode# 将hadoop-2.8.1-src.tar.gz下载（或者用rz上传）到sourcecode目录[root@hadoop000 sourcecode]# lltotal 33756-rw-r--r--. 1 root root 34523353 Aug 20 12:14 hadoop-2.8.1-src.tar.gz# 解压[root@hadoop000 sourcecode]# tar -xzvf hadoop-2.8.1-src.tar.gz[root@hadoop000 sourcecode]# lltotal 33760drwxr-xr-x. 17 root root     4096 Jun  2 14:13 hadoop-2.8.1-src-rw-r--r--.  1 root root 34523353 Aug 20 12:14 hadoop-2.8.1-src.tar.gz[root@hadoop000 sourcecode]# cd hadoop-2.8.1-src

2.JAVA安装

[root@hadoop000 ~]# mkdir -p /usr/java[root@hadoop000 ~]# cd /usr/java[root@hadoop000 java]# rz #上传jdk-8u45-linux-x64.gz[root@hadoop000 java]# tar -xzvf jdk-8u45-linux-x64.gz# 设置环境变量[root@hadoop000 java]# vi /etc/profile# 在最底下加入export JAVA_HOME=/usr/java/jdk1.8.0_45export PATH=$JAVA_HOME/bin:$PATH# 生效[root@hadoop000 java]# source /etc/profile

3.Maven安装

[root@hadoop000 ~]# cd /opt/software/[root@hadoop000 software]# rz  #上传apache-maven-3.3.9-bin.zip[root@hadoop000 software]# lltotal 8432-rw-r--r--. 1 root root 8617253 Aug 20 12:35 apache-maven-3.3.9-bin.zip# 解压[root@hadoop000 software]# unzip apache-maven-3.3.9-bin.zip# 设置环境变量[root@hadoop000 software]# vi /etc/profileexport MAVEN_HOME=/opt/software/apache-maven-3.3.9export MAVEN_OPTS="-Xms256m -Xmx512m"export PATH=$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH# 生效[root@hadoop000 software]# source /etc/profile# 查看[root@hadoop000 software]# mvn -versionApache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)Maven home: /opt/software/apache-maven-3.3.9Java version: 1.8.0_45, vendor: Oracle CorporationJava home: /usr/java/jdk1.8.0_45/jreDefault locale: en_US, platform encoding: UTF-8OS name: "linux", version: "2.6.32-431.el6.x86_64", arch: "amd64", family: "unix"

4.Findbugs安装

[root@hadoop000 ~]# cd /opt/software/[root@hadoop000 software]# rz #上传findbugs-1.3.9.zip# 解压[root@hadoop000 software]# unzip findbugs-1.3.9.zip# 设置环境变量[root@hadoop000 software]# vi /etc/profileexport FINDBUGS_HOME=/opt/software/findbugs-1.3.9export PATH=$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH# 生效[root@hadoop000 software]# source /etc/profile# 查看[root@hadoop000 software]# findbugs -version1.3.9

5.protobuf安装

[root@hadoop000 ~]# cd /opt/software/[root@hadoop000 software]# rz #上传protobuf-2.5.0.tar.gz# 解压[root@hadoop000 software]# tar -xzvf protobuf-2.5.0.tar.gz[root@hadoop000 software]# cd protobuf-2.5.0[root@hadoop000 protobuf-2.5.0]# yum install -y gcc gcc-c++ make cmake[root@hadoop000 protobuf-2.5.0]# ./configure --prefix=/usr/local/protobuf[root@hadoop000 protobuf-2.5.0]# make && make install# 设置环境变量[root@hadoop000 java]# vi /etc/profileexport PROTOC_HOME=/usr/local/protobufexport PATH=$PROTOC_HOME/bin:$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH# 生效[root@hadoop000 protobuf-2.5.0]# source /etc/profile# 查看[root@hadoop000 protobuf-2.5.0]# protoc --versionlibprotoc 2.5.0

6.安装其他依赖

yum install -y openssl openssl-devel svn ncurses-devel zlib-devel libtoolyum install -y snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop autoconf automake

7.编译

[root@hadoop000 sourcecode]# cd hadoop-2.8.1-src[root@hadoop000 hadoop-2.8.1-src]# mvn clean package -Pdist,native -DskipTests -Dtar#稍等一段时间 出现以下信息即编译完成[INFO] ------------------------------------------------------------------------[INFO] BUILD SUCCESS[INFO] ------------------------------------------------------------------------[INFO] Total time: 13:38 min[INFO] Finished at: 2018-05-16T15:18:47+08:00[INFO] Final Memory: 173M/478M[INFO] ------------------------------------------------------------------------
