大数据之----部署安装编译打包hadoop终极篇

------------------------------软件版本-------------------------------------- RHEL6.8 hadoop2.8.1 apache-maven-3.3.9 findbugs-1.3.9 protobuf-2.5.0.tar.gz jdk-8u45

------------------------------软件版本---------------------------------------

大数据概述 可以用“5V + 1C”来概括：

Variety 多样化 Volume 海量 Velocity 快速 Vitality 灵活 Value 价值性 Complexity 复杂

1.Hadoop生态

宏观: Hadoop为主的生态圈 hadoop flume........

狭义: apache hadoop  hadoop.apache.org

2.Hadoop(存储+计算+资源和作业调度)

hadoop1.x  

    HDFS      存储

    MapReduce 计算+资源和作业调度

hadoop2.x  企业正在用

    MapReduce 计算

    YARN      资源和作业调度平台 计算组件都会on yarn

hadoop3.x  ???

EC技术：Erasure Encoding 简称EC，是Hadoop3给HDFS拓展的一种新特性，用来解决存储空间文件。

YARN：提供YARN的时间轴服务V.2，以便用户和开发人员可以对其进行测试，并提供反馈意见。

优化Hadoop Shell脚本

重构Hadoop Client Jar包

支持随机Container

MapReduce任务级本地优化

支持多个NameNode

部分默认服务端口被改变

支持文件系统连接器

DataNode内部添加了负载均衡

重构后台程序和任务对管理

2.Maven部署

2.1解压

[root@hadoop1 softwore]# pwd

/opt/softwore

[root@hadoop1 softwore]# ls

apache-maven-3.3.9-bin.zip  hadoop-2.8.1-src.tar.gz  jdk-8u45-linux-x64.gz

findbugs-1.3.9.zip          hadoop-2.8.1.tar.gz      protobuf-2.5.0.tar.gz

[root@hadoop1 softwore]# unzip apache-maven-3.3.9-bin.zip

--配置环境变量

[root@hadoop1 softwore]#

vi /etc/profile

export MAVEN_HOME=/opt/software/apache-maven-3.3.9

export MAVEN_OPTS="-Xms256m -Xmx512m"

export PATH=$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH

[root@hadoop1 softwore]# source /etc/profile

[root@hadoop1 apache-maven-3.3.9]# mvn --version

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)

Maven home: /opt/software/apache-maven-3.3.9

Java version: 1.8.0_45, vendor: Oracle Corporation

Java home: /usr/java/jdk1.8.0_45/jre

Default locale: zh_CN, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-358.el6.x86_64", arch: "amd64", family: "unix"

Maven部署为二进制部署，解压配置环境变量

2.2配置mavne目录

2.3查看配置文件和 解压我们准备好的仓库文件

3.Hadoop编译

编译hadoop 通过Requirements我看可以知道需要安装jdk maven findbugs protocolBuffer cmake Zlib openssl-devel 等软件

3.1解压

3.2查看pom.xml

3.3查看BUILDING.txt

Requirements:编译软件环境要求

* Unix System

* JDK 1.7+

* 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 and to get the best HDFS encryption performance)

* Linux FUSE (Filesystem in Userspace) version 2.6 or above (if compiling fuse_dfs)

* Internet connection for first build (to fetch all Maven and Hadoop dependencies)

3.4 JDK部署

[root@hadoop1 softwore]# tar -zxvf jdk-8u45-linux-x64.gz    -C /usr/java[root@hadoop1 softwore]# ls -ld /usr/java/*

drwxr-xr-x 8 root root 4096 12月 15 2016 /usr/java/djdk1.7.0_79

drwxr-xr-x 8 uucp  143 4096 4月  11 2015 /usr/java/jdk1.8.0_45

drwxr-xr-x 8 uucp  143 4096 10月  7 2015 /usr/java/jdk1.8.0_65

[root@hadoop1 softwore]# vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_45

export JRE_HOME=/usr/java/jdk1.8.0_45/jre

[root@hadoop1 softwore]# java -version

java version "1.8.0_45"

Java(TM) SE Runtime Environment (build 1.8.0_45-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

二进制版本解压，配置环境变量即可

3.5 MAVEN

上面我们已经安装maven和jdk检测版本是否满足我们编译软件要求

[root@hadoop1 softwore]# mvn --version

Default locale: en_US, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-431.el6.x86_64", arch: "amd64", family: "unix"

3.6 FINDBUGS

[root@hadoop1 softwore]#  unzip findbugs-1.3.9.zip

[root@hadoop1 softwore]# vi /etc/profile

  export FINDBUGS_HOME=/opt/software/findbugs-1.3.9

  export PATH=$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH [root@hadoop1 softwore]# source /etc/profile

[root@hadoop1 softwore]# findbugs -version

1.3.9

二进制安装解压，配置环境变量即可

3.7 PROTOCBUF编译安装

[root@hadoop1 software]# tar xvf  protobuf-2.5.0.tar.gz

[root@hadoop1 yum.repos.d]# yum install -y gcc gcc-c++ make cmake   ---编译环境

[root@hadoop1 yum.repos.d]#cd /opt/software/protobuf-2.5.0

[root@hadoop1 protobuf-2.5.0]# ./configure --prefix=/usr/local/protobuf

[root@hadoop1 protobuf-2.5.0]# make && make install

[root@hadoop1 protobuf-2.5.0]# vim /etc/profile

export PROTOC_HOME=/usr/local/protobuf

export PATH=$PROTOC_HOME/bin:$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH

[root@hadoop1 software]# source /etc/profile

[root@hadoop1 software]# protoc --version

libprotoc 2.5.0

[root@hadoop000 local]#

编译安装完成，配置环境变量

3.8 OTHER 依赖包

yum install -y openssl openssl-devel svn ncurses-devel zlib-devel libtool

yum install -y snappy snappy-devel bzip2 bzip2-devel \n

zo lzo-devel lzop autoconf automake

其他依赖包在系统安装ios都包含，执行yum安装即可

---------------------------------------------------------------------------------------------------------------------------------------

至此，编译hadoop需要的编译环境全部准备好，下面开启编译之路

3.9 编译

[root@hadoop1 software]# tar xvf hadoop-2.8.1-src.tar.gz

[root@hadoop1 software]# cd hadoop-2.8.1-src

[root@hadoop1 hadoop-2.8.1-src]# pwd

/opt/software/hadoop-2.8.1-src

[root@hadoop1 hadoop-2.8.1-src]#

mvn clean package -Pdist,native -DskipTests –Dtar

/opt/software/hadoop-2.8.1-src/hadoop-dist/target/hadoop-2.8.1.tar.gz

----编译好软件包保存位置

直接编译需要联网找依赖包，一般网络情况较好，需要几个小时

提前准备好依赖包编译方式

[root@hadoop1 hadoop-2.8.1-src]# ls pom.xml  ---根据这个文件下载jar

pom.xml

[root@hado

-rw-r--r--   1 root   root  96721446 4月  25 09:57 .m2.tar.gz   ---提前下好的仓库软件包

[root@hadoop1 software]#tar xvf .m2.tar.gz –C /root   ---不想download，使用提前准备好的仓库软件--->解压----->root家目录

[root@hadoop1 hadoop-2.8.1-src]# mvn clean package -Pdist,native -DskipTests –Dtar
