Hadoop-3.1.3部署

1.准备3台机器  2核2G即可

在每台机器配置 /etc/hosts

添加：（192.168.56.211（master节点），192.168.56.212（node1节点），192.168.56.213（node2节点））每台机器都添加

修改每台机器名字

[root@master~]# vim /etc/hostname
master

[root@master ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.211 master
192.168.56.212 node1
192.168.56.213 node2

[root@master ~]# 

图例：

2.3台机器配置免密登录

ssh-keygen -t rsa
#一路回车即可 然后分发到每台机器，包括当前机器
ssh-copy-id master
ssh-copy-id node1
ssh-copy-id node2
#注意：
还需要在 master上采用 root 账号配置一下无密登录到 master、node1、
node2服务器上。
还需要在 node1上采用 root 账号配置一下无密登录到 master、node1、
node2服务器上。
还需要在 node2上采用 root 账号，配置一下无密登录到 master、node1、
node2；

如：

3. 在/opt 目录下创建 module、software 文件夹

[root@master~]# mkdir /opt/module
[root@master~]# mkdir /opt/software

4.下载链接：（Hadoop3.1.3下载路径）

https://archive.apache.org/dist/hadoop/common/hadoop-3.1.3/

5.每台机器都要配置java环境变量

如：（/opt/jdk/jdk1.8.0_202  环境变量下面会用到）

[root@master ~]# echo $JAVA_HOME
/opt/jdk/jdk1.8.0_202
[root@master ~]# java -version
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
[root@master ~]# 

6.把hadoop上传到linux目录：(每台机器都需要配置环境变量)

1）进入到 Hadoop 安装包路径下
[root@master ~]$ cd /opt/software/
2）解压安装文件到/opt/module 下面
[root@master software]$ tar -zxvf hadoop-3.1.3.tar.gz -C 
/opt/module/
3）查看是否解压成功
[root@master software]$ ls /opt/module/
hadoop-3.1.3
4）将 Hadoop 添加到环境变量
（1）获取 Hadoop 安装路径
[root@master hadoop-3.1.3]$ pwd
/opt/module/hadoop-3.1.3
（2）打开/etc/profile.d/my_env.sh 文件
[root@master hadoop-3.1.3]$ sudo vim
/etc/profile.d/my_env.sh
在 my_env.sh 文件末尾添加如下内容：（shift+g）
#HADOOP_HOME
export HADOOP_HOME=/opt/module/hadoop-3.1.3
export PATH=$PATH:$HADOOP_HOME/bin
export PATH=$PATH:$HADOOP_HOME/sbin
➢ 保存并退出： :wq
（3）让修改后的文件生效
[root@master hadoop-3.1.3]$ source /etc/profile

测试是否安装成功
[root@master hadoop-3.1.3]$ hadoop version
Hadoop 3.1.3
5）重启（如果 Hadoop 命令不能用再重启虚拟机）
[root@master hadoop-3.1.3]$ sudo reboot

7.运行WordCount示例：

7.1 本地运行模式（官方 WordCount）
1）创建在 hadoop-3.1.3 文件下面创建一个 wcinput 文件夹
[root@master hadoop-3.1.3]$ mkdir wcinput
2）在 wcinput 文件下创建一个 word.txt 文件
[root@master hadoop-3.1.3]$ cd wcinput
3）编辑 word.txt 文件
[root@master wcinput]$ vim word.txt
➢ 在文件中输入如下内容
hadoop yarn
hadoop mapreduce
➢ 保存退出：:wq
4）回到 Hadoop 目录/opt/module/hadoop-3.1.3
5）执行程序
[root@master hadoop-3.1.3]$ hadoop jar 
share/hadoop/mapreduce/hadoop-mapreduce-examples-3.1.3.jar 
wordcount wcinput wcoutput
6）查看结果
[root@master hadoop-3.1.3]$ cat wcoutput/part-r-00000
看到如下结果：
hadoop 2
mapreduce 1
yarn 1

8.1）集群部署规划
注意：
➢ NameNode 和 SecondaryNameNode 不要安装在同一台服务器
➢ ResourceManager 也很消耗内存，不要和 NameNode、SecondaryNameNode 配置在
同一台机器上。

2）配置文件说明
Hadoop 配置文件分两类：默认配置文件和自定义配置文件，只有用户想修改某一默认
配置值时，才需要修改自定义配置文件，更改相应属性值。
（1）默认配置文件：
要获取的默认文件 文件存放在 Hadoop 的 jar 包中的位置
[core-default.xml] hadoop-common-3.1.3.jar/core-default.xml
[hdfs-default.xml] hadoop-hdfs-3.1.3.jar/hdfs-default.xml
[yarn-default.xml] hadoop-yarn-common-3.1.3.jar/yarn-default.xml
[mapred-default.xml] hadoop-mapreduce-client-core-3.1.3.jar/mapred-default.xml
（2）自定义配置文件：
core-site.xml、hdfs-site.xml、yarn-site.xml、mapred-site.xml 四个配置文件存放在
$HADOOP_HOME/etc/hadoop 这个路径上，用户可以根据项目需求重新进行修改配置。
3）配置集群
（1）核心配置文件
配置 core-site.xml

[root@master ~]$ cd $HADOOP_HOME/etc/hadoop
[root@master hadoop]$ vim core-site.xml

文件如下：

 
 fs.defaultFS
 hdfs://master:8020
 
 
 
 hadoop.tmp.dir
 /opt/module/hadoop-3.1.3/data
 
 
 
 hadoop.http.staticuser.user
 root
 

（2）HDFS 配置文件
配置 hdfs-site.xml

[root@master hadoop]$ vim hdfs-site.xml

文件内容如下：

 




 dfs.namenode.http-address
 master:9870
 

 
 dfs.namenode.secondary.http-address
 node2:9868
 

（3）YARN 配置文件
配置 yarn-site.xml

[root@master hadoop]$ vim yarn-site.xml

文件内容如下：

 
 yarn.nodemanager.aux-services
 mapreduce_shuffle
 
 
 
 yarn.resourcemanager.hostname
 node1
 
 
 
 yarn.nodemanager.env-whitelist
 
JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CO
NF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAP
RED_HOME
 

 

 yarn.log-aggregation-enable
 true


 
 yarn.log.server.url 
 http://master:19888/jobhistory/logs



 yarn.log-aggregation.retain-seconds
 604800

（4）MapReduce 配置文件

配置 mapred-site.xml

[root@master hadoop]$ vim mapred-site.xml

文件内容如下：

 
 mapreduce.framework.name
 yarn
 

  yarn.app.mapreduce.am.env
  HADOOP_MAPRED_HOME=/opt/module/hadoop-3.1.3


  mapreduce.map.env
  HADOOP_MAPRED_HOME=/opt/module/hadoop-3.1.3


  mapreduce.reduce.env
  HADOOP_MAPRED_HOME=/opt/module/hadoop-3.1.3




 mapreduce.jobhistory.address
 master:10020



 mapreduce.jobhistory.webapp.address
 master:19888

1）配置 workers

[root@master hadoop]$ vim /opt/module/hadoop3.1.3/etc/hadoop/workers

在该文件中增加如下内容：

master
node1
node2

编辑 hadoop-env.sh 添加 java运行环境目录：

export JAVA_HOME=/opt/jdk/jdk1.8.0_202

hadoop-3.1.3\sbin\ start-dfs.sh      stop-dfs.sh 添加root用户启动

#!/usr/bin/env bash
HDFS_DATANODE_USER=root
HADOOP_SECURE_DN_USER=hdfs
HDFS_NAMENODE_USER=root
HDFS_SECONDARYNAMENODE_USER=root

hadoop-3.1.3\sbin\ start-yarn.sh      stop-yarn.sh 添加root用户启动

#!/usr/bin/env bash
YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root

2）启动集群
（1）如果集群是第一次启动，需要在 master节点格式化 NameNode（注意：格式
化 NameNode，会产生新的集群 id，导致 NameNode 和 DataNode 的集群 id 不一致，集群找
不到已往数据。如果集群在运行过程中报错，需要重新格式化 NameNode 的话，一定要先停
止 namenode 和 datanode 进程，并且要删除所有机器的 data 和 logs 目录，然后再进行格式
化。）

[root@master hadoop-3.1.3]$ hdfs namenode -format

（2）启动 HDFS

[root@master hadoop-3.1.3]$ sbin/start-dfs.sh

（3）在配置了 ResourceManager 的节点（node1）启动 YARN

[root@node1  hadoop-3.1.3]$ sbin/start-yarn.sh

3）在 master 启动历史服务器
 

[root@master hadoop-3.1.3]$ mapred --daemon start historyserver

（4）Web 端查看 HDFS 的 NameNode
（a）浏览器中输入：http://hadoop100:9870
（b）查看 HDFS 上存储的数据信息
（5）Web 端查看 YARN 的 ResourceManager
（a）浏览器中输入：http://hadoop101:8088
（b）查看 YARN 上运行的 Job 信息

windows需要配置映射：（C:\Windows\System32\drivers\etc）修改HOSTS文件添加如下内容

192.168.56.211 hadoop100
192.168.56.212 hadoop101
192.168.56.213 hadoop102

192.168.56.211 master
192.168.56.211 06762320a7eb
192.168.56.212 node1
192.168.56.213 node2

master:命令如下：

etc/hadoop文件与 sbin 已上传github

1.windows环境

在CMD窗口输入   hadoop如果是 不是内部命令或者是不能识别hadoop命令

可以使用下面方式测试：（把路径直接放在Path下）

winutils 我是用的是：hadoop-3.1.2的 是已经上传到github （如有需要可以下载）
