篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了VMware12使用三台虚拟机Ubuntu16.04系统搭建hadoop-2.7.1+hbase-1.2.4（完全分布式）相关的知识，希望对你有一定的参考价值。

初衷

首先说明一下既然网上有那么多教程为什么要还要写这样一个安装教程呢？网上教程虽然多，但是有些教程比较老，许多教程忽略许多安装过程中的细节，比如添加用户的权限，文件权限，小编在安装过程遇到许多这样的问题所以想写一篇完整的教程，希望对初学hadoop的人有一个直观的了解，我们接触真集群的机会比较少，虚拟机是个不错的选择，可以基本完全模拟真实的情况，前提是你的电脑要配置相对较好不然跑起来都想死，废话不多说。

环境说明

本文使用VMware® Workstation 12 Pro虚拟机创建并安装三台Ubuntu16.04系统分别命名为master、slave1、slave2对应对应NameNode、DataNode、DataNode。
安装过程中要求三个系统中配置基本相同除个别配置（比如：节点的命名）
192.168.190.128 master
192.168.190.129 slave1
192.168.190.131 slave2

在虚拟机Linux上安装与配置Hadoop

需要说明的是下面的所有配置三台Ubuntu系统都要配置而且是基本一样，为了使配置一致，先在一台机器上配置然后将对应配置scp到其他机器上
虚拟机的安装不是本文重点，这里就不赘述了。安装之后是这样的：
这里写图片描述
在Linux上安装Hadoop之前，需要安装两个程序：
1）JDK1.6(或更高版本),本文采用JDK 1.7。Hadoop是Java编写的程序，Hadoop的编译及MapReduce都需要使用JDK。因此，在安装Hadoop前，必须安装JDK1.6或更高版本。
2)SSH(安装外壳协议)，推荐安装OpenSSH.Hadoop需要通过SSH来启动Slave列表中各台机器的守护进程，因此SSH也是必须安装的，即使是安装伪分布版本（因为Hadoop并没有区分集群式和伪分布式）。对于伪分布式，Hadoop会采用与集群相同处理方式，即按次序启动文件conf/slaves中记载的主机上的进程，只不过在伪分布式中Slave为localhost（即本身），所以对于伪分布式Hadoop，SSH也是一样必须的。

部署步骤

添加一个hadoop用户，并赋予相应权利，我们接下来hadoop hbase的安装都要在hadoop用户下操作，所以hadoop用户要将hadoop的文件权限以及文件所有者赋予给hadoop用户。
1.每个虚拟机系统上都添加 hadoop 用户，并添加到 sudoers

sudo adduser hadoop

sudo gedit /etc/sudoers

找到对应添加如下：

# User privilege specification
root    ALL=(ALL:ALL) ALL
hadoop ALL=(ALL:ALL) ALL

2.切换到 hadoop 用户：

su hadoop

3.修改 /etc/hostname 主机名为 master
当然master虚拟机设置为master
其他两个虚拟机分别设置为slave1、slave2
4.、修改 /etc/hosts

127.0.0.1 localhost
127.0.1.1   localhost.localdomain   localhost
192.168.190.128 master
192.168.190.129 slave1
192.168.190.131 slave2
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

5.安装JDK 1.7

(1)下载和安装JDK 1.7
jdk-7u76-linux-x64.tar.gz
使用tar命令

tar -zxvf jdk-7u76-linux-x64.tar.gz

将安装文件移动到JDK安装目录，本文JDK的安装目录为/usr/lib/jvm/jdk1.7.0_76
（2）配置环境变量
输入命令：

sudo gedit /etc/profile

输入密码，打开profile文件。在最下面输入如下内容：

#set java environment
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_76
export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
export PATH=${JAVA_HOME}/bin:/home/hadoop/hadoop-2.7.1/bin:/home/hadoop/hadoop-2.7.1/sbin:/home/hadoop/hbase-1.2.4/bin:$PATH

需要说明的是可能profile文件当前权限是只读的，需要使用

sudo chmod 777 /etc/profile

命令修改文件读写权限。文件中已经包含了Hadoop以及Hbase的环境配置。
这一步的意义是配置环境变量，使系统可以找到JDK。
（4）验证JDK是否安装成功
输入命令：

java -version

会出现如下JDK版本信息：

java version "1.7.0_76"
Java(TM) SE Runtime Environment (build 1.7.0_76-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.76-b04, mixed mode)

如果出现上述JDK版本信息说明当前安装JDK并未设置成Ubuntu系统默认的JDK，接下来还需要手动将安装的JDK设置成系统默认的JDK。
(5)手动设置系统默认JDK
在终端依次输入命令：

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_76/bin/java 300

sudo update-alternatives --install  /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_76/bin/javac 300

sudo update-alternatives --config java

接下来输入java -version就可以看到所安装的JDK的版本信息了。
三台虚拟机都要安装Vmware Tools工具方便复制粘贴

6.配置SSH免密码登录
(1)确认已经连上互联网，然后输入命令：

sudo apt-get install ssh

(2)配置 master、slave1 和 slave2 节点可以通过 SSH 无密码互相访问
注意这里的所有操作都是在hadoop用户下操作的。
首先，查看下hadoop用户下是否存在.ssh文件夹（注意ssh文件前面有”.”这是一个隐藏文件夹），输入命令：

ls -a -l

可以得到

drwxr-xr-x  9 root   root 4096 Feb  1 02:41 .
drwxr-xr-x  4 root   root 4096 Jan 27 01:50 ..
drwx------  3 root   root 4096 Jan 31 03:35 .cache
drwxr-xr-x  5 root   root 4096 Jan 31 03:35 .config
drwxrwxrwx 11 hadoop root 4096 Feb  1 00:18 hadoop-2.7.1
drwxrwxrwx  8 hadoop root 4096 Feb  1 02:47 hbase-1.2.4
drwxr-xr-x  3 root   root 4096 Jan 31 03:35 .local
drwxr-xr-x  2 root   root 4096 Jan 31 14:47 software
drwxr-xr-x  2 hadoop root 4096 Feb  1 00:01 .ssh

一般来说，安装SSH时会自动在当前用户下创建这个隐藏文件夹，如果没有，可以手动创建一个。

sudo mkdir .ssh

注意这里的.ssh要是hadoop权限拥有，如果是root的话，使用下面命令：

sudo chown -R hadoop .ssh

接下来，输入命令：

ssh-keygen -t rsa

如果没有权限前面加一个sudo.
执行完可以看到一个图标并在.ssh文件下创建两个文件：id_rsa和id_rsa.pub

 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

在Ubuntu中，~代表单前用户文件夹，此处即/home/hadoop。
这表命令的功能是把公钥加到用于认证的公钥文件中，这里的authorized_keys是用于认证的公钥文件。
然后使用命令：

sudo gedit authorized_keys

打开对应虚拟机生成的密码，如master主机的hadoop用户生成了hadoop@master，将其他主机生成的秘钥添加到master主机的authorized_keys文件的末尾，这样master主机就拥有slave1的hadoop用户以及slave2的hadoop用户的秘钥了。
如下：
不要复制我的，复制我的没用，我这里只是实例一下，复制你自己的三台虚拟机各自生成的秘钥

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC743oCP2Voa3deHBkA+N7cYJC4Jv2Tj8Z6tGVWCxg0NJl3yKwYIfgC9RiyFyRWcl5byI34Oe7dYtf+9UtvH85hca1/IDP1m02NLPXsIJmcPS4uNgMLfsWg/F/C3Bqut7i4t6eHwO/FRhjeIBu5O/9GHoXk/ykhgJIbyh8hhAlcke6Jtt80I63r2+3DnlHlNzw1sQRJp2qFRgyV61j5DfuYrhfd+/eTkFtXc7izLVCkC7x6hMo4qIMQ0GbSx9iqTO0tO1skGYLhCX3Cbo3hf4i19RUKt168eg/X2l1qIvf+vgxQudM3lZa9/pxDieK5p8c8xupcaoR67jMFLWLl3EUb hadoop@master

至此免密码登录主机已配置完毕。
（3）验证SSH是否已安装成功，以及是否可以免密码登录主机。
输入命令：

ssh -V

显示结果：

OpenSSH_7.2p2 Ubuntu-4ubuntu2.1, OpenSSL 1.0.2g  1 Mar 2016

输入命令：

ssh localhost

会有如下显示：

这说明已经安装成功，第一次登录会询问是否继续链接，输入yes即可以进入。
实际上，在Hadoop的安装过程中，是否免密码登录是无关紧要的，但是如果不配置免密码登录，每次启动Hadoop都需要输入密码以登录到每台机器的DataNode上，考虑到一般的Hadoop集群动辄数百或者上千台机器，因此一般来说都会配置SSH免密码登录。
master 节点无密码访问 slave1 和 slave2 节点：

ssh slave1

运行结果：

不需要密码，需要密码说明没有配置成功，看看是不是哪步出现了问题。

安装并运行Hadoop

介绍Hadoop的安装之前，先介绍一下Hadoop对各个节点的角色定义。
Hadoop分别从三个角度将主机划分为两种角色。第一，最基本的划分为Master和Slave,即主人和奴隶；第二，从HDFS的角度，将主机划分为NameNode和DataNode(在分布式文件系统中，目录的管理很重要，管理目录相当于主任，而NameNode就是目录管理者）；第三，从MapReduce角度，将主机划分为JobTracker和TaskTracker(一个Job经常被划分为多个Task,从这个角度不难理解它们之间的关系)。
Hadoop有三种运行方式：单机模式、伪分布与完全分布式。乍看之下，前两种并不能体现云计算的优势，但是它们便于程序的测试与调试，所以还是有意义的。
我的博客中有介绍单机模式和伪分布式方式这里就不赘述，本文主要着重介绍分布式方式配置。
（1）hadoop 用户目录下解压下载的hadoop-2.7.1.tar.gz
使用解压命令：

tar -zxvf hadoop-2.7.1.tar.gz

注意一下操作都是在hadoop用户下操作的也就是hadoop-2.7.1的所有者是hadoop.如下所示：

total 120
drwxr-xr-x 19 hadoop hadoop 4096 Feb  1 02:28 .

-rw-------  1 hadoop hadoop   51 Feb  1 00:55 .Xauthority
-rw-------  1 hadoop hadoop 1492 Feb  1 00:58 .xsession-errors

（2）配置 hadoop 的环境变量

sudo gedit /etc/profile

配置如下：

#set java environment
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_76
export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
export PATH=${JAVA_HOME}/bin:/home/hadoop/hadoop-2.7.1/bin:/home/hadoop/hadoop-2.7.1/sbin:/home/hadoop/hbase-1.2.4/bin:$PATH

(3)配置三台主机的Hadoop文件，内容如下。
conf/Hadoop-env.sh:
/home/master/hadoop-2.7.1/etc/hadoop
首先如何找到这个文件呢，使用Ubuntu的搜索工具如图所示：
这里写图片描述
配置如下：

# The java implementation to use.
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_76
export HADOOP_HOME=/home/master/hadoop-2.7.1
export PATH=$PATH:/home/master/hadoop-2.7.1/bin

conf/core-site.xml

搜索发现没有这个文件需要复制mapred-site.xml.template这个文件的内容到mapred-site.xml

cp mapred-site.xml.template mapred-site.xml

配置如下：

没有手动添加一个master文件
配置如下：

master

conf/slaves:

slave1
slave2

（4）向 slave1 和 slave2 节点复制 hadoop2.7.1 整个目录至相同的位置
进入hadoop@master节点hadoop目录下使用

scp -r hadoop-2.7.1 hadoop@slave1:~/
scp -r hadoop-2.7.1 hadoop@slave2:~/

(5)启动Hadoop
在hadoop@master节点上执行

hadoop@master:~$ hadoop namenode -format

如果提示：

hadoop: command not found

需要source一下环境变量文件

source /etc/profile

执行结果如下：

hadoop@master:~$ hadoop namenode -format

Instead use the hdfs command for it.
