篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何安装单节点的hadoop相关的知识,希望对你有一定的参考价值。
参考技术A 没用,失去了使用Hadoop的意义,实际使用都是多节点的;还有学习、实验等,也建议使用多节点。Hadoop伪集群(单节点集群)安装(Centos7)
Hadoop 搭建单节点集群(伪集群)

本文档介绍如何设置和配置单节点 Hadoop 安装,以便您可以使用 Hadoop MapReduce 和 Hadoop 分布式文件系统 (HDFS) 快速执行简单的操作。
学习接触Hadoop,但是生产环境不建议使用。
环境配置
环境 | 版本 |
---|---|
系统 | centos7.6 |
JDK | java11 |
Hadoop | 3.3.3 |
先决条件
支持的平台
- 支持 GNU/Linux 作为开发和生产平台。Hadoop 已在具有 2000 个节点的 GNU/Linux 集群上进行了演示。
- Windows 也是受支持的平台,但以下步骤仅适用于 Linux。要在 Windows 上设置 Hadoop,请参阅wiki 页面。
所需基础软件
- 必须安装 Java™。这里使用了java11,具体安装方式可以参考 : linux安装java11
- 如果要使用可选的启动和停止脚本,则必须安装 ssh 并且必须运行 sshd 才能使用管理远程 Hadoop 守护程序的 Hadoop 脚本。此外,建议同时安装 pdsh 以更好地管理 ssh 资源。
下载安装包
要获得 Hadoop 发行版,请从Apache 下载镜像之一下载最近的稳定版本。
以hadoop3.3.3为例 :
wget https://dlcdn.apache.org/hadoop/common/hadoop-3.3.3/hadoop-3.3.3.tar.gz --no-check-certificate
--no-check-certificate
声明不检查证书
解压安装包
tar -xvf hadoop-3.3.3.tar.gz
配置Hadoop单点集群
配置JDK Hadoop环境变量
编辑在解压包下的 etc/hadoop/hadoop-env.sh
编辑
export JAVA_HOME=/home/install/jdk/jdk-11
Hadoop命令说明
$ bin/hadoop
配置 core-site.xml
编辑 解压包下的 etc/hadoop/core-site.xml 文件,添加如下配置
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
配置 hdfs-site.xml
编辑 解压包下的 etc/hadoop/hdfs-site.xml 文件,添加如下配置
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
设置无密码SSH
创建ssh公私钥
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
以公钥创建授权key
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
授权
chmod 0600 ~/.ssh/authorized_keys
开始安装
格式化namenode
bin/hdfs namenode -format
正确的格式化命令执行结果见下方
执行nameNode格式化命令成功控制台输出
启动 NameNode 守护进程和 DataNode 守护进程
sbin/start-dfs.sh
启动成功访问势力
NameNode访问地址 : http://localhost:9870/
访问效果如下 :
执行nameNode格式化命令成功控制台输出 :
