一、安装JDK
yum install java-1.8*二、关闭防火墙
systemctl status firewalld
systemctl stop firewalld
systemctl disable firewalld三、配置ip地址和主机名映射
vi /etc/hosts
加入：
192.168.1.1 hadoop001四、配置免密登录
1、生成公私钥
ssh-keygen -t rsa2、写入公钥到授权文件
cd /root/.ssh/
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys五、建立安装目录
mkdir -p /appserver/hadoop六、下载安装包
cd /root
wget https://archive.apache.org/dist/hadoop/common/hadoop-3.3.4/hadoop-3.3.4.tar.gz
七、解压安装包
tar -zxvf tar -zxvf hadoop-3.3.4.tar.gz -C /appserver/hadoop/解压到目录为：/appserver/hadoop/hadoop-3.3.4
Hadoop目录结构
bin etc include lib libexec LICENSE-binary licenses-binary LICENSE.txt logs NOTICE-binary NOTICE.txt README.txt sbin share
1、bin目录
会用到hdfs、mapred、yarn命令
2、etc目录
提供大量的配置文件
core-site.xml，核心配置
hdfs-site.xml，和hdfs相关的
mapred-site.xml，和计算相关的
yarn-site.xml，和yarn相关的
workers，后期会用到
3、sbin目录
启动脚本
start-dfs.sh，启动HDFS
start-yarn.sh，启动yarn
mr-jobhistory-daemon.sh，启动历史服务器
4、share目录
学习资料和官方案例
八、hadoop的配置
1、修改hadoop-env.sh
配置JAVA_HOME，yum安装openjdk的路径在/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.362.b08-1.el7_9.x86_64
cd /appserver/hadoop/hadoop-3.3.4/etc/hadoop/
vi hadoop-env.sh
加入：
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.362.b08-1.el7_9.x86_64
2、测试hadoop环境
bin/hadoop version
Hadoop 3.3.4
Source code repository https://github.com/apache/hadoop.git -r a585a73c3e02ac62350c136643a5e7f6095a3dbb
Compiled by stevel on 2022-07-29T12:32Z
Compiled with protoc 3.7.1
From source with checksum fb9dd8918a7b8a5b430d61af858f6ec
This command was run using /appserver/hadoop/hadoop-3.3.4/share/hadoop/common/hadoop-common-3.3.4.jar
3、修改core-site.xml
（1）指定namenode的hdfs协议文件系统的通信地址
（2）指定hadoop存储临时文件的目录
vi core-site.xml
<configuration>
<property>
<!--指定 namenode 的 hdfs 协议文件系统的通信地址-->
<name>fs.defaultFS</name>
<value>hdfs://hadoop001:8020</value>
</property>
<property>
<!--指定 hadoop 存储临时文件的目录-->
<name>hadoop.tmp.dir</name>
<value>/appserver/hadoop/tmp</value>
</property>
</configuration>4、修改hdfs-site.xml
（1）设置namenode节点数据保存目录
（2）设置datanode节点数据保存目录
（3）指定副本数量，在分布式文件系统中，数据通常会被冗余的存储多份，以保证可靠性和安全性，但是这里用的是伪分布式模式，节点只有一个，也有就只有一个副本
vi hdfs-site.xml
<configuration>
<property>
<!--设置namenode节点数据保存目录-->
<name>dfs.namenode.name.dir</name>
<value>/appserver/hadoop/namenode/data</value>
</property>
<property>
<!--datanode节点数据保存目录-->
<name>dfs.datanode.data.dir</name>
<value>/appserver/hadoop/datanode/data</value>
</property>
<property>
<!--指定副本数量-->
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>5、修改mapred-site.xml
（1）指定mapreduce作业运行在yarn上
vi mapred-site.xml
<configuration>
<property>
<!--指定 mapreduce 作业运行在 yarn 上-->
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>6、修改yarn-site.xml
（1）配置NodeManager上运行的附属服务。需要配置成mapreduce_shuffle后才可以在Yarn上运行MapReduce程序
（2）配置resourcemanager在哪个节点上
vi yarn-site.xml
<configuration>
<property>
<!--配置 NodeManager 上运行的附属服务。需要配置成 mapreduce_shuffle 后才可以在 Yarn 上运行 MapReduce 程序。-->
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<!--resourcemanager 的主机名-->
<name>yarn.resourcemanager.hostname</name>
<value>hadoop001</value>
</property>
</configuration>7、slaves文件
（1）在/appserver/hadoop/hadoop-3.3.4/etc/hadoop/下建立slaves，配置节点的主机名或IP地址
（2）单机版本，指定本机即可
（3）真集群环境下，所有从属节点上的DataNode服务和NodeManager服务都会被启动
vi slaves
hadoop001九、首次启动格式化HDFS
cd /appserver/hadoop/hadoop-3.3.4/bin
./hdfs namenode -format

vi /etc/profile
添加：
export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_SECONDARYNAMENODE_USER=root
export YARN_RESOURCEMANAGER_USER=root
export YARN_NODEMANAGER_USER=root
source /etc/profile十一、进入到sbin目录下
1、启动dfs服务
./start-dfs.sh
