在上一篇博客，博主爲你們講述了centos6.9上編譯hadoop2.9.1全過程，這一章節博主將帶着你們一塊兒來安裝hadoop。java

本篇博客中可能用到的額外的命令：node

#關閉selinux
sudo vi /etc/sysconfig/selinux
修改enforcing爲disabled
#查看防火牆狀態
sudo service iptables status
#關閉防火牆
sudo service iptables stop
#永久關閉防火牆
sudo chkconfig iptables off
#copy主機配置文件到其它服務器
sudo scp  /etc/hosts centos-aaron-h2:/etc/hosts

1、首先上傳編譯好的hadoop2.9.1.tar.gz（建議使用ALT+P上傳）linux

2、新建apps文件夾，而且解壓hadoop文件web

#進入hadoop用戶目錄
cd ~
#新建apps目錄
mkdir apps
#解壓hadoop文件
tar -zxvf centos6.9-hadoop-2.9.1.tar.gz -C apps/

3、進入hadoop目錄，認識下sql

bin 操做命令
sbin 系統啓動管理命令
etc 配置文件
include c語言本地庫的頭文件
lib 本地庫
share doc文檔、 jar包shell

4、進入hadoop2.9.1的etc/hadoop配置文件目錄，配置環境apache

a.修改hadoop-env.sh中JAVA_HOME目錄爲真實目錄json

b. 配置core-site.xml文件windows

<configuration>
<!-- name node file system -->
<property>
        <name>fs.defaultFS</name>
        <value>hdfs://centos-aaron-h1:9000</value>
</property>
<!-- hadoop process work data dir -->
<property>
        <name>hadoop.tmp.dir</name>
        <value>/home/hadoop/hdpdata</value>
</property>
</configuration>

c.配置hadf-site.xml文件centos

<configuration>
<!--  set replication 2 default 3      -->
<property>
        <name>dfs.replication</name>
        <value>2</value>
</property>
</configuration>

d.配置mapred-site.xml

<configuration>
<!--  默認爲local  -->
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>

e.配置yarn-site.xml

<configuration>
<!-- Site specific YARN configuration properties -->
<!-- 配置yarn集羣的resourcemanager -->
<property>
        <name>yarn.resourcemanager.hostname</name>
        <value>centos-aaron-h1</value>
</property>
<!-- 配置yarn集羣的爲reduce提供shuffle的服務 -->
<property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
</property>
</configuration>

5、將配置好的hadoop分發到其它幾臺服務器

sudo scp -r apps  hadoop@centos-aaron-h2:/home/hadoop
sudo scp -r apps  hadoop@centos-aaron-h3:/home/hadoop
sudo scp -r apps  hadoop@centos-aaron-h4:/home/hadoop

6、配置hadoop環境變量

#編輯配置
vi /etc/profile
   export JAVA_HOME=/usr/local/jdk1.7.0_45
   export HADOOP_HOME=/home/hadoop/apps/hadoop-2.9.1
   export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
#發佈配置
sudo scp  /etc/profile centos-aaron-h2:/etc/
sudo scp  /etc/profile centos-aaron-h3:/etc/
sudo scp  /etc/profile centos-aaron-h4:/etc/
#讓配置當即生效
source /etc/profile

7、hdfs格式化，格式化namenode（是對centos-aaron-h1上namenode進行初始化）

[hadoop@centos-aaron-h1 ~]$ hdfs namenode -format
18/10/31 07:57:10 INFO namenode.NameNode: STARTUP_MSG: 
/************************************************************
STARTUP_MSG: Starting NameNode

根據執行結果能夠知道/home/hadoop/hdpdata/dfs/name/current/爲namenode的工做目錄,裏面包含一些數據的元信息

8、分步驟啓動hadoop

a.啓動namenode，執行命令：hadoop-daemon.sh start namenode

b.驗證namenode web後臺是否能夠訪問：http://centos-aaron-h1:50070

c.在centos-aaron-h二、h三、h4上啓動data node，執行命令：hadoop-daemon.sh start datanode

d.在namenode後臺檢查是否啓動成功

e.分步驟關閉hadoop,執行命令

hadoop-daemon.sh stop datanode
hadoop-daemon.sh stop namenode

9、修改slaves配置文件

vi /home/hadoop/apps/hadoop-2.9.1/etc/hadoop/slaves
#新增覆蓋
cetnos-aaron-h2
cetnos-aaron-h3
cetnos-aaron-h4

十、配置h1到h一、h二、h三、h4的免密登陸（用於使用hadoop sbin目錄下一鍵啓動）

#生成
ssh-keygem
#發佈ssh公鑰
ssh-copy-id centos-aaron-h1
ssh-copy-id centos-aaron-h2
ssh-copy-id centos-aaron-h3
ssh-copy-id centos-aaron-h4

十一、腳本啓動hdfs，執行命令：start-dfs.sh，可查看secondNameNode和nameNode的管理臺

十二、腳本啓動yarn，執行命令：start-yarn.sh，打開mr後臺:http://centos-aaron-h1:8088

至此，hadoop的集羣搭建完畢.
