3.4实训任务 Hadoop环境搭建与安装
一、官网下载HadoopApache Hadoophttps://hadoop.apache.org/releases.htmlWindows在Apache官网下载需要版本的Binary文件，再通过XFTP传输到CentOS虚拟机。二、安装Hadoop0、在xshell中输入ls命令查看文件目录1、在Xshell中点击xftp2、找到下载下来的Hadoop···.tar.gz文件，双击该文件开始上
·
一、官网下载Hadoop
Apache Hadoop
https://hadoop.apache.org/releases.html
Windows在Apache官网下载需要版本的Binary文件，再通过XFTP传输到CentOS虚拟机。
二、传输Hadoop
0、在xshell中输入ls命令查看文件目录
1、在Xshell中点击xftp
2、找到下载下来的Hadoop···.tar.gz文件，双击该文件开始上传
3、传输完成
4、再在xshell中输入ls查看文件目录，看是否上传成功
5、在XFTP中新建Opt文件夹
6、把Hadoop···.tar.gz文件移动到Opt文件夹中
7、解压Hadoop
进入Xshell中
①进入hadoop-2.10.1.tar.gz所在文件位置
cd /home/bigdata/Opt②解压hadoop-2.10.1.tar.gz到当前文件目录
tar -zxvf hadoop-2.10.1.tar.gz
解压后的文件目录：
三、配置Hadoop
首先，由于Hadoop是Java进程，所以需要添加JDK。配置Hadoop前要先安装JDK，
JDK的下载和安装以及配置可以参考此文：
Linux中安装JDK_懒笑翻的博客-CSDN博客
配置SSH无密码登录可以参考此文：
1、Hadoop伪分布式安装，先找到配置文件路径
2、修改 core-site.xml 配置文件
输入命令：
vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/core-site.xml回车后，点击键盘 i 即可进入输入模式
在core-site.xml 中增加配置信息：
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://192.168.232.131:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>file:/home/bigdata/Opt/hadoop-2.10.1/tmp</value>
</property>
</configuration>
需要注意的是配置文件中原本就有<configuration></configuration>标签，把其他配置信息放在里面就行了。
按 ESC 退出编辑后，输入 :wq 保存并退出core-site.xml
3、修改 hadoop-env.sh 文件配置Hadoop运行环境，用来定义Java环境变量。
输入命令：
vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/hadoop-env.sh输入下图中配置信息【路径和文件名对应你自己的哈】：
配置信息输入完后，按ESC键，然后 :wq 保存并退出
4、修改hdfs-site.xml文件来配置HDFS
vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/hdfs-site.xml<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/name</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/home/bigdata/Opt/hadoop-2.10.1/tmp/dfs/data</value>
</property>
</configuration>
按 ESC 退出编辑后，输入 :wq 保存并退出
5、修改配置 mapred-site.xml 文件来配置MapReduce 参数
①由于 /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop 目录下只有/mapred-site.xml.template文件
② 下面我们 复制 mapred-site.xml.template 文件生成mapred-site.xml 文件
输入命令：
scp mapred-site.xml.template mapred-site.xml
③修改 mapred-site.xml 配置信息，指明Hadoop的MR将来运行于YARN资源调度系统上
vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/mapred-site.xml<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
按 ESC 退出编辑后，输入 :wq 保存并退出
6、配置 yarn-site.xml 文件，用于配置集群资源管理系统参数
vim /home/bigdata/Opt/hadoop-2.10.1/etc/hadoop/yarn-site.xml<configuration>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>192.168.232.131</value>
</property>
<property>
<name>yarn.nodemanager.aux-service</name>
<value>mapreduce_shuffle</value>
</property>
</configuration> 
按 ESC 退出编辑后，输入 :wq 保存并退出
7、配置Hadoop环境变量
需要先使用root权限，使用root登录
su root输入命令：
vim /etc/profile
#set hadoop enviroment
export HADOOP_HOME=/home/bigdata/Opt/hadoop-2.10.1
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
按 ESC 退出编辑后，输入 :wq 保存并退出
8、刷新配置
输入命令：
source /etc/profile9、配置完成后，执行 NameNode 的格式化
进入 /home/bigdata/Opt/hadoop-2.10.1/sbin 目录
cd /home/bigdata/Opt/hadoop-2.10.1/sbin执行命令：
hdfs namenode -format
[root@localhost hadoop]# cd /home/bigdata/Opt/hadoop-2.10.1/sbin
[root@localhost sbin]# hdfs namenode -format
22/04/24 10:03:35 INFO namenode.NameNode: STARTUP_MSG:

10、开启所有服务
进入 /home/bigdata/Opt/hadoop-2.10.1/sbin 目录
cd /home/bigdata/Opt/hadoop-2.10.1/sbin执行命令：
./start-all.sh
通过 jps 命令来查看所有服务是否启动
11、开启NameNode和DataNode
进入 /home/bigdata/Opt/hadoop-2.10.1/sbin 目录
cd /home/bigdata/Opt/hadoop-2.10.1/sbin执行命令：
./start-dfs.sh
12、Hadoop中HDFS还提供Web访问页面，默认端口 50070，通过HTTP协议访问
13、Hadoop集群信息也提供Web访问页面，默认端口8088，通过HTTP协议访问
