安装环境
虚拟软件：VMware® Workstation 16 Pro
虚拟机操作系统：CentOS 7.9-Minimal
虚拟机 IP：192.168.153.11、192.168.153.12、192.168.153.13
前期规划
Hadoop 集群包含两个集群：HDFS 集群、YARN 集群，两个集群在逻辑上分离，但通常会共用主机。
两个集群都是标准的主从架构集群。
HDFS 集群包含的角色（守护进程）：
- 主角色：NameNode
- 从角色：DataNode
- 主角色辅助角色：SecondaryNameNode
YARN 集群包含的角色（守护进程）：
- 主角色：ResourceManager
- 从角色：NodeManager
集群规划：
| 服务器 | IP 地址 | 运行角色（守护进程） |
|---|---|---|
| node1.hadoop.com | 192.168.153.11 | NameNode DataNode ResourceManager NodeManager |
| node2.hadoop.com | 192.168.153.12 | SecondaryNameNode DataNode NodeManager |
| node3.hadoop.com | 192.168.153.13 | DataNode NodeManager |
环境配置
每台虚拟机都要配置，使用 root 用户。
1、关闭防火墙
systemctl stop firewalld systemctl disable firewalld
2、同步时间
yum -y install ntpdate ntpdate ntp5.aliyun.com
3、配置主机名
vi /etc/hostname
按照规划，将三台虚拟机的主机名分别设置为：node1.hadoop.com、node2.hadoop.com 和 node3.hadoop.com。
4、配置 hosts 文件
vi /etc/hosts
添加下面的内容：
192.168.153.11 node1 node1.hadoop.com 192.168.153.12 node2 node1.hadoop.com 192.168.153.13 node3 node1.hadoop.com
5、安装 JDK
yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel
配置 JAVA_HOME
cat <<EOF | tee /etc/profile.d/hadoop_java.sh export JAVA_HOME=\$(dirname \$(dirname \$(readlink \$(readlink \$(which javac))))) export PATH=\$PATH:\$JAVA_HOME/bin EOF source /etc/profile.d/hadoop_java.sh
确认：
echo $JAVA_HOME
6、创建 hadoop 用户，并设置密码
adduser hadoop usermod -aG wheel hadoop passwd hadoop
创建 HDFS 本地存放数据的目录：
mkdir /home/hadoop/data chown hadoop: /home/hadoop/data
7、配置环境变量
echo 'export HADOOP_HOME=/home/hadoop/hadoop-3.3.2' >> /etc/profile echo 'export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin' >> /etc/profile source /etc/profile
8、配置 SSH
yum install openssh
切换到 hadoop 用户，执行下面的命令。
ssh-keygen ssh-copy-id node1 ssh-copy-id node2 ssh-copy-id node3
每台虚拟机都要执行，执行过程如下：
[hadoop@node1 ~]$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/hadoop/.ssh/id_rsa): Created directory '/home/hadoop/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/hadoop/.ssh/id_rsa.

[hadoop@node1 ~]$
下载安装
先在 node1 虚拟机进行安装配置，然后把安装好的目录复制到另外两台虚拟机。（使用 hadoop 用户）
1、下载并解压
使用 hadoop 用户连接 node1 虚拟机，用下面的命令下载安装包到 /home/hadoop 目录。
cd /home/hadoop curl -Ok https://dlcdn.apache.org/hadoop/common/hadoop-3.3.2/hadoop-3.3.2.tar.gz
解压：
tar zxf hadoop-3.3.2.tar.gz
接下来通过配置文件对 Hadoop 进行配置。
Hadoop 的配置文件分为三类：
- 默认配置文件 -- 包括
core-default.xml、hdfs-default.xml、yarn-default.xml和mapred-default.xml，这些文件是只读的，存放的是参数的默认值。 - 自定义配置文件 -- 包括
etc/hadoop/core-site.xml、etc/hadoop/hdfs-site.xml、etc/hadoop/yarn-site.xml和etc/hadoop/mapred-site.xml，用来存放自定义配置信息，将会覆盖默认配置。 - 环境配置文件 -- 包括
etc/hadoop/hadoop-env.sh、etc/hadoop/mapred-env.sh和etc/hadoop/yarn-env.sh，这些文件用来配置各守护进程的 Java 运行环境。
2、配置 hadoop-env.sh 文件
cd hadoop-3.3.2 vi etc/hadoop/hadoop-env.sh
添加下面这些内容：
export JAVA_HOME=$JAVA_HOME
export HDFS_NAMENODE_USER=hadoop
export HDFS_DATANODE_USER=hadoop
export HDFS_SECONDARYNAMENODE_USER=hadoop
export YARN_RESOURCEMANAGER_USER=hadoop
export YARN_NODEMANAGER_USER=hadoop
至少要配置 JAVA_HOME 环境变量，另外可以通过下面这些变量，为不同的守护进程单独进行配置：
| 守护进程 | 环境变量 |
|---|---|
| NameNode | HDFS_NAMENODE_OPTS |
| DataNode | HDFS_DATANODE_OPTS |
| Secondary NameNode | HDFS_SECONDARYNAMENODE_OPTS |
| ResourceManager | YARN_RESOURCEMANAGER_OPTS |
| NodeManager | YARN_NODEMANAGER_OPTS |
| WebAppProxy | YARN_PROXYSERVER_OPTS |
| Map Reduce Job History Server | MAPRED_HISTORYSERVER_OPTS |
例如，给 Namenode 配置使用 parallelGC 和 4GB 堆内存：
export HDFS_NAMENODE_OPTS="-XX:+UseParallelGC -Xmx4g"
3、配置 core-site.xml 文件
该文件将会覆盖 core-default.xml 中的配置。
vi etc/hadoop/core-site.xml
添加下面的内容：
<!-- 设置默认使用的文件系统 Hadoop 支持 file、HDFS、GFS、Ali Cloud、Amazon Cloud 等文件系统 -->
<property>
<name>fs.defaultFS</name>
<value>hdfs://node1:8020</value>
</property>
<!-- 设置 Hadoop 本地保存数据的路径 -->

<value>*</value>
</property>
<!-- 文件垃圾桶保存时间 -->
<property>
<name>fs.trash.interval</name>
<value>1440</value>
</property>
4、配置 hdfs-site.xml 文件
该文件将会覆盖 hdfs-default.xml 中的配置。
vi etc/hadoop/hdfs-site.xml
添加下面的内容：
<!-- 设置 SNN 进程运行机器位置信息 -->
<property>
<name>dfs.namenode.secondary.http-address</name>
<value>node2:9868</value>
</property>
5、配置 mapred-site.xml 文件
该文件将会覆盖 mapred-default.xml 中的配置。
vi etc/hadoop/mapred-site.xml
添加下面的内容：
<!-- 设置 MR 程序默认运行模式：yarn 集群模式，local 本地模式-->
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<!-- MR 程序历史服务地址 -->
<property>
<name>mapreduce.jobhistory.address</name>
<value>node1:10020</value>
</property>
<!-- MR 程序历史服务器 web 端地址 -->
<property>
<name>mapreduce.jobhistory.webapp.address</name>
<value>node1:19888</value>
</property>
<property>
<name>yarn.app.mapreduce.am.env</name>
<value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
</property>
<property>
<name>mapreduce.map.env</name>
<value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
</property>
<property>
<name>mapreduce.reduce.env</name>
<value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
</property>
6、配置 yarn-site.xml 文件
该文件将会覆盖 yarn-default.xml 中的配置。
vi etc/hadoop/yarn-site.xml
添加下面的内容：
<!-- 设置 YARN 集群主角色运行机器位置 -->
<property>
<name>yarn.resourcemanager.hostname</name>
<value>node1</value>
</property>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<!-- 是否对容器实施物理内存限制 -->
<property>
<name>yarn.nodemanager.pmem-check-enabled</name>
<value>false</value>
</property>
<!-- 是否对容器实施虚拟内存限制 -->
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
<!-- 开启日志聚集-->
<property>
<name>yarn.log-aggregation-enable</name>
<value>true</value>
</property>
<!-- 设置 yarn 历史服务器地址 -->
<property>
<name>yarn.log.server.url</name>
<value>http://node1:19888/jobhistory/logs</value>
</property>
7、配置 workers 文件
vi etc/hadoop/workers
删除原来内容，并添加下面的内容：
node1.hadoop.com node2.hadoop.com node3.hadoop.com
8、将配置好的安装包复制到 node2 和 node3 机器。
scp -r /home/hadoop/hadoop-3.3.2 hadoop@node2:/home/hadoop/ scp -r /home/hadoop/hadoop-3.3.2 hadoop@node3:/home/hadoop/
启动集群
Hadoop 提供了两种启动方式：
- 使用命令逐个启动进程 -- 每台机器都要手动执行命令，可精准控制每个进程的启动。
- 使用脚本一键启动 -- 前提是要配置好机器之间的 SSH 免密登录和
etc/hadoop/workers文件。
逐个启动进程的命令：
# HDFS 集群
$HADOOP_HOME/bin/hdfs --daemon start namenode | datanode | secondarynamenode
# YARN 集群
$HADOOP_HOME/bin/yarn --daemon start resourcemanager | nodemanager | proxyserver
启动集群的脚本：
- HDFS 集群 --
$HADOOP_HOME/sbin/start-dfs.sh，一键启动 HDFS 集群的所有进程。 - YARN 集群 --
$HADOOP_HOME/sbin/start-yarn.sh，一键启动 YARN 集群的所有进程 - Hadoop 集群 --
$HADOOP_HOME/sbin/start-all.sh，一键启动 HDFS 集群和 YARN 集群的所有进程。
1、格式化文件系统
启动集群之前，需要对 HDFS 进行格式化（仅在 node1 机器执行）。
[hadoop@node1 ~]$ hdfs namenode -format WARNING: /home/hadoop/hadoop-3.3.2/logs does not exist. Creating. 2022-03-17 23:22:55,296 INFO namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host =

2、启动 HDFS 集群
start-dfs.sh
该脚本将会启动 NameNode 守护进程和 DataNode 守护进程：
[hadoop@node1 hadoop-3.3.2]$ start-dfs.sh Starting namenodes on [node1] Starting datanodes node1.hadoop.com: Warning: Permanently added 'node1.hadoop.com' (ECDSA) to the list of known hosts. node3.hadoop.com: ssh: Could not resolve hostname node3.hadoop.com: Name or service not known node2.hadoop.com: ssh: Could not resolve hostname node2.hadoop.com: Name or service not known Starting secondary namenodes [node2] node2: WARNING: /home/hadoop/hadoop-3.3.2/logs does not exist. Creating. [hadoop@node1 hadoop-3.3.2]$ [hadoop@node1 hadoop-3.3.2]$ jps 5001 DataNode 5274 Jps 4863 NameNode [hadoop@node1 hadoop-3.3.2]$
启动成功后，可以在浏览器访问 NameNode 的 Web 界面（默认端口：9870）：
3、启动 YARN 集群
start-yarn.sh
该脚本将会启动 ResourceManager 守护进程和 NodeManager 守护进程：
[hadoop@node1 hadoop-3.3.2]$ start-yarn.sh Starting resourcemanager Starting nodemanagers node3.hadoop.com: ssh: Could not resolve hostname node3.hadoop.com: Name or service not known node2.hadoop.com: ssh: Could not resolve hostname node2.hadoop.com: Name or service not known [hadoop@node1 hadoop-3.3.2]$ [hadoop@node1 hadoop-3.3.2]$ jps 5536 NodeManager 5395 ResourceManager 5001 DataNode 5867 Jps 4863 NameNode [hadoop@node1 hadoop-3.3.2]$
启动成功后，可以在浏览器访问 ResourceManager 的 Web 界面（默认端口：8088）：
除了 start-dfs.sh 和 start-yarn.sh 脚本，也可使用 start-all.sh 脚本，一次性启动 Hadoop 的所有进程。
停止集群
和启动集群一样，Hadoop 提供了两种方式停止集群。
逐个终止进程的命令：
# HDFS 集群
$HADOOP_HOME/bin/hdfs --daemon stop namenode | datanode | secondarynamenode
# YARN 集群
$HADOOP_HOME/bin/yarn --daemon stop resourcemanager | nodemanager | proxyserver
停止集群的脚本：
- HDFS 集群 --
$HADOOP_HOME/sbin/stop-dfs.sh，一键终止 HDFS 集群的所有进程。 - YARN 集群 --
$HADOOP_HOME/sbin/stop-yarn.sh，一键终止 YARN 集群的所有进程 - Hadoop 集群 --
$HADOOP_HOME/sbin/stop-all.sh，一键终止 HDFS 集群和 YARN 集群的所有进程。
使用 stop-all.sh 脚本，一次性停止 Hadoop 的所有进程。
[hadoop@node1 hadoop-3.3.2]$ stop-all.sh WARNING: Stopping all Apache Hadoop daemons as hadoop in 10 seconds. WARNING: Use CTRL-C to abort.
