【Hadoop篇06】Hadoop源码编译
没有谁必须要帮助你,任何事情都得靠自己去完成
Hadoop源码编译
准备工作
(1)CentOS联网
配置CentOS能连接外网。Linux虚拟机ping是畅通的
注意:采用root角色编译,减少文件夹权限出现问题
(2)jar包准备(hadoop源码、JDK8、maven、ant 、protobuf)
(1)hadoop-2.7.2-src.tar.gz
(2)jdk-8u144-linux-x64.tar.gz
(3)apache-ant-1.9.9-bin.tar.gz(build工具,打包用的)
(4)apache-maven-3.0.5-bin.tar.gz
(5)protobuf-2.5.0.tar.gz(序列化的框架)
编译工具安装
(1)安装JDK
[root@hadoop101 software] # tar -zxf jdk-8u144-linux-x64.tar.gz -C /opt/module/
[root@hadoop101 software]# vi /etc/profile
\#JAVA_HOME:
export JAVA_HOME=/opt/module/jdk1.8.0_144
export PATH=$PATH:$JAVA_HOME/bin
[root@hadoop101 software]#source /etc/profile
验证命令:java -version
(2)Maven解压、配置 MAVEN_HOME和PATH
[root@hadoop101 software]# tar -zxvf apache-maven-3.0.5-bin.tar.gz -C /opt/module/
[root@hadoop101 apache-maven-3.0.5]# vi conf/settings.xml
<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>
</mirror>
-->
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>
[root@hadoop101 apache-maven-3.0.5]# vi /etc/profile
\#MAVEN_HOME
export MAVEN_HOME=/opt/module/apache-maven-3.0.5
export PATH=$PATH:$MAVEN_HOME/bin
[root@hadoop101 software]#source /etc/profile
验证命令:mvn -version
(3)配置ANT
[root@hadoop101 software]# tar -zxvf apache-ant-1.9.9-bin.tar.gz -C /opt/module/
[root@hadoop101 apache-ant-1.9.9]# vi /etc/profile
\#ANT_HOME
export ANT_HOME=/opt/module/apache-ant-1.9.9
export PATH=$PATH:$ANT_HOME/bin
[root@hadoop101 software]#source /etc/profile
验证命令:ant -version
(4)安装 glibc-headers 和 g++
[root@hadoop101 apache-ant-1.9.9]# yum install glibc-headers
[root@hadoop101 apache-ant-1.9.9]# yum install gcc-c++
(5)安装make和cmake
[root@hadoop101 apache-ant-1.9.9]# yum install make
[root@hadoop101 apache-ant-1.9.9]# yum install cmake
(6)安装protobuf
[root@hadoop101 software]# tar -zxvf protobuf-2.5.0.tar.gz -C /opt/module/
[root@hadoop101 opt]# cd /opt/module/protobuf-2.5.0/
[root@hadoop101 protobuf-2.5.0]#./configure
[root@hadoop101 protobuf-2.5.0]# make
[root@hadoop101 protobuf-2.5.0]# make check
[root@hadoop101 protobuf-2.5.0]# make install
[root@hadoop101 protobuf-2.5.0]# ldconfig
[root@hadoop101 hadoop-dist]# vi /etc/profile
\#LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/module/protobuf-2.5.0
export PATH=$PATH:$LD_LIBRARY_PATH
[root@hadoop101 software]#source /etc/profile
验证命令:protoc --version
(7)安装openssl库
[root@hadoop101 software]#yum install openssl-devel
(8)安装 ncurses-devel库
[root@hadoop101 software]#yum install ncurses-devel
到此,编译工具安装基本完成
编译源码
(1)解压源码到/opt/目录
[root@hadoop101 software]# tar -zxvf hadoop-2.7.2-src.tar.gz -C /opt/
(2)进入到hadoop源码主目录
[root@hadoop101 hadoop-2.7.2-src]# pwd
/opt/hadoop-2.7.2-src
(3)通过maven执行编译命令
[root@hadoop101 hadoop-2.7.2-src]#mvn package -Pdist,native -DskipTests -Dtar
等待时间30分钟左右,最终成功是全部SUCCESS
# 成功的64位hadoop包在/opt/hadoop-2.7.2-src/hadoop-dist/target下
[root@hadoop101 target]# pwd
/opt/hadoop-2.7.2-src/hadoop-dist/target
(4)编译源码过程中常见的问题及解决方案
(1)MAVEN install时候JVM内存溢出
处理方式:在环境配置文件和maven的执行文件均可调整MAVEN_OPT的heap大小。(详情查阅MAVEN 编译 JVM调优问题,如:http://outofmemory.cn/code-snippet/12652/maven-outofmemoryerror-method)
(2)编译期间maven报错。可能网络阻塞问题导致依赖库下载不完整导致,多次执行命令(一次通过比较难):
[root@hadoop101 hadoop-2.7.2-src]#mvn package -Pdist,nativeN -DskipTests -Dtar
(3)报ant、protobuf等错误,插件下载未完整或者插件版本问题,最开始链接有较多特殊情况,同时推荐
