VMware12使用三台虚拟机Ubuntu 16.04系统搭建Hadoop-2.7.1+HBase-1.2.4（完全分布式）

共计 37321 个字符，预计需要花费 94 分钟才能阅读完成。

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：

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：

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

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

说明初始格式化文件系统成功！
启动 Hadoop
注意启动 Hadoop 是在主节点上执行命令，其他节点不需要，主节点会自动按照文件配置启动从节点

hadoop@master:~$ start-all.sh

执行结果如下：

hadoop@master:~$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [master]
master: starting namenode, logging to /home/hadoop/hadoop-2.7.1/logs/hadoop-hadoop-namenode-master.out

slave2: starting nodemanager, logging to /home/hadoop/hadoop-2.7.1/logs/yarn-hadoop-nodemanager-slave2.out

可以通过 jps 命令查看各个节点运行的进程查看运行是否成功。
master 节点：

hadoop@master:~$ jps
11012 Jps
10748 ResourceManager
10594 SecondaryNameNode

slave1 节点：

hadoop@slave1:~$ jps
7227 Jps
7100 NodeManager
6977 DataNode

slave2 节点：

hadoop@slave2:~$ jps
6654 Jps
6496 NodeManager
6373 DataNode

你可以通过以下命令或者通过 http://master:50070 查看集群状态。

至此 Haoop 的安装配置已经全部讲完。

HBase 的安装

HBase 有三种运行模式，其中单机模式的配置非常简单，几乎不用对安装文件做任何修改就可以使用。如果要运行分布式模式，Hadoop 是必不可少的。另外在对 HBase 的某些文件进行配置之前，需要具备一下先决条件也是我们刚才介绍 Hadoop 介绍过的。
（1）JDK
(2)Hadoop
(3)SSH

完全分布式模式安装

对于完全分布式安装 HBase, 我们需要通过 hbase-site.xml 文档来配置本机的 HBase 特性，通过 hbase-env.sh 来配置全局 HBase 集群系统的特性，也就是说每一台机器都可以通过 hbase-env.sh 来了解全局的 HBase 的某些特性。另外，各个 HBase 实例之间需要通过 Zookeeper 来进行通信，因此我们还需要维护一个（一组）Zookeeper 系统。
首先通过查看下 hbase 文件的所有者和权限

ls -a -l

得到如下：

total 36
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

（1）conf/hbase-site.xml 文件的配置
hbase.rootdir 和 hbase.cluster.distributed 两个参数的配置对于 HBase 来说是必须的。我们通过 hbase.rootdir 来指定本台机器 HBase 的存储目录；通过 hbase.cluster.distributed 来说明其运行模式（true 为全分布式模式，false 为单机模式或伪分布式模式）；另外 hbase.master 指定的是 HBase 的 master 位置，hbase.zookeeper.quorum 指定的是 Zookeeper 集群的位置。如下所示为示例配置文档：
同样，通过 Ubuntu 的目录查找 hbase-site.xml
/home/hadoop/hbase-1.2.4/conf
配置如下：

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="https://www.linuxidc.com/Linux/2017-08/configuration.xsl"?>

（2）conf/regionservers 的配置
regionservers 文件列出了所有运行 HBase RegionServer CHRegion Server 的机器。此文件的配置和 Hadoop 的 slaves 文件十分类似，每一行指定一台机器。当 HBase 启动的时候，会将此文件中列出的机器启动；同样，当 HBase 关闭的时候，也会同时自动读取文件并将所有机器关闭。
在我们配置中，HBase Master 及 HDFS NameNode 运行在 hostname 为 Master 的机器上，HBase RegionServers 运行在 master、slave1、slave2 上。根据上述配置，我们只需要将每台机器上 HBase 安装目录下的 conf/regionservers 文件的内容设置为：
/home/hadoop/hbase-1.2.4/conf

master
slave1
slave2

另外，我们可以将 HBase 的 Master 和 HRegionServer 服务器分开。这样只需要在上述配置文件中删除 master 一行即可。
（3）Zookeeper 配置
完全分布式的 HBase 集群需要 Zookeeper 实例运行，并且需要所有的 HBase 节点能够与 Zookeeper 实例通信。默认情况下 HBase 自身维护着一组默认的 Zookeeper 实例。不过，用户可以配置独立的 Zookeeper 实例，这样能够使 HBase 系统更加健壮。
conf/hbase-env.sh 配置文档中 HBASE_MANAGES_ZK 的默认值为 true, 它表示 HBase 使用自身所带的 Zookeeper 实例。但是，该实例只能为单机或者伪分布式模式下的 HBase 提供服务。当安装完全分布模式时需要配置自己的 Zookeeper 实例。在 HBase-site.xml 文档中配置了 hbase.zookeeper.quorum 属性后，系统将有限使用该属性所指定的 Zookeeper 列表。此时，若 HBASE_MANAGES_ZK 变量值为 true, 那么在启动 HBase 时，Hbase 将把 Zookeeper 作为自身的一部分运行，其对应进程为“HQuorumPeer”; 若该变量值为 false，那么在启动 HBase 之前必须首先手动运行 hbase.zookeeper.quorum 属性所指定的 Zookeeper 集群，其对应的进程显示为 QuorumPeerMain. 若将 Zookeeper 作为 HBase 的一部分来运行，那么关闭 HBase 时 Zookeeper 将被自动关闭，否则需要手动停止 Zookeeper 服务。

运行 Hbase

运行之前，在 hdfs 文件系统中添加 hbase 目录：

hdfs dfs -mkdir hdfs://master:9000/hbase

执行 start-hbase.sh

hadoop@master:~$ start-hbase.sh
slave1: starting zookeeper, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-zookeeper-slave1.out
slave2: starting zookeeper, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-zookeeper-slave2.out
master: starting zookeeper, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-zookeeper-master.out
starting master, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-master-master.out
master: starting regionserver, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-regionserver-master.out
slave2: starting regionserver, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-regionserver-slave2.out
slave1: starting regionserver, logging to /home/hadoop/hbase-1.2.4/logs/hbase-hadoop-regionserver-slave1.out

在启动 Hbase 之后，用户可以通过下面命令进入 HBase Shell 之中：

hbase shell

成功进入之后，用户会看到如下所示：

hadoop@master:~$ hbase shell
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/hadoop/hbase-1.2.4/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

hbase(main):001:0>

进去 HBase Shell 输入 status 命令，如果看到如下结果，证明 HBase 安装成功。

hbase(main):009:0> status
1 active master, 0 backup masters, 3 servers, 0 dead, 0.6667 average load

输入 list

hbase(main):010:0> list
TABLE                                                                           
0 row(s) in 0.3250 seconds

=> []

至此 hbase 安装已经全部讲完了，过程主要出现的问题是权限问题，如果 hadoop 文件放在 root 目录下，而在 hadoop 用户目录下会出现访问权限问题，访问 hadoop 目录权限不够也是问题，比如 hadoop 在 /home/ 目录下，需要赋予相应权限，希望对初学 hadoop,hbase 的人有所帮助！
