<code>[hadoop@master ~]$ </code><code>cat</code>  <code>/etc/redhat-release</code> 

<code>CentOS Linux release 7.2.1511 (Core) </code>

<code>[hadoop@master ~]$ </code>

<code>[hadoop@master ~]$ getenforce </code>

<code>Disabled</code>

<code>[hadoop@master ~]$ systemctl  status  firewalld </code>

<code>● firewalld.service - firewalld - dynamic firewall daemon</code>

<code>   </code><code>Loaded: loaded (</code><code>/usr/lib/systemd/system/firewalld</code><code>.service; disabled; vendor preset: enabled)</code>

<code>   </code><code>Active: inactive (dead)</code>

<code>[hadoop@master ~]$</code>

2.IP以及對應節點

IP

主機名

hadoop node

hadoop  程序名稱

192.168.56.100

master

namenode,jobtracker

192.168.56.101

slave1

slave

datanode,tasktracker

192.168.56.102

slave2

192.168.56.103

slave3

<code>[hadoop@master ~]</code><code># cat  /etc/hosts</code>

<code>192.168.56.100  Master</code>

<code>192.168.56.101  slave1</code>

<code>192.168.56.102  slave2</code>

<code>192.168.56.103  slave3</code>

<code>[hadoop@master ~]</code><code>#</code>

3.增加hadoop使用者，所有節點

<code>useradd</code>  <code>hadoop</code>

<code>echo</code> <code>hadoop|</code><code>passwd</code>  <code>--stdin  hadoop</code>

4.jdk

<code>[hadoop@slave1 application]</code><code># ll</code>

<code>total 4</code>

<code>lrwxrwxrwx 1 root root   24 Jul 10 01:35 jdk -&gt; </code><code>/application/jdk1</code><code>.8.0_60</code>

<code>drwxr-xr-x 8 root root 4096 Aug  5  2015 jdk1.8.0_60</code>

<code>[hadoop@slave1 application]</code><code># pwd</code>

<code>/application</code>

<code>[hadoop@slave1 application]</code><code># </code>

<code>[hadoop@master ~]</code><code># java  -version </code>

<code>java version </code><code>"1.8.0_60"</code>

<code>Java(TM) SE Runtime Environment (build 1.8.0_60-b27)</code>

<code>Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)</code>

5.master(192.168.56.100)上的hadoop使用者可以ssh所有slave節點的hadoop使用者下

6.設定hadoop安裝路徑 以及環境變量（所有節點）

<code>su</code>  <code>-  hadoop</code>

<code>tar</code> <code>xf  hadoop-2.7.0tar.gz</code>

<code>/home/hadoop/hadoop-2</code><code>.7.0</code>

<code>vi</code> <code>/etc/profile</code>  <code>添加hadoop環境變量</code>

<code>export</code> <code>HADOOP_HOME=</code><code>/home/hadoop/hadoop-2</code><code>.7.0</code>

<code>export</code> <code>PATH=$PATH:$HADOOP_HOME</code><code>/bin</code>

<code>source</code> <code>/etc/profile</code>

7.修改hadoop的環境的Java環境變量

<code>/home/hadoop/hadoop-2</code><code>.7.0</code><code>/etc/hadoop</code>

<code>vi</code> <code>hadoop-</code><code>env</code><code>.sh 添加</code>

<code>###JAVA_HOME</code>

<code>export</code> <code>JAVA_HOME=</code><code>/application/jdk/</code>

8.修改hadoop的配置檔案
