Hadoop环境搭建

Hadoop环境搭建

在/opt目录下创建两个目录

1. software: 存储jar包
2. module: 存储解压jar后的程序

JDK下载地址

Hadoop下载地址

官网地址

# 创建目录
sudo mkdir /opt/software
sudo mkdir /opt/module

# 修改目录的所有者和所有组
sudo chown lzd:lzd /opt/software /opt/module

# 上传jdk、Hadoop-方案一，下载本地拷贝上去
scp jdk-14.0.2_linux-x64_bin.tar.gz room@[ip]:/opt/software
scp hadoop-2.10.0.tar.gz room@[ip]:/opt/software

# 上传jdk-、Hadoop方案一，直接wget
wget -P /opt/software https://download.oracle.com/otn-pub/java/jdk/14.0.2+12/205943a0976c4ed48cb16f1043c5c647/jdk-14.0.2_linux-x64_bin.tar.gz?AuthParam=1597588035_9d4b49461fbfa78a01c92e092c587d90
wget -P /opt/software https://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.10.0/hadoop-2.10.0.tar.gz

# 解压jdk、、Hadoop
tar -zxvf /opt/software/jdk-14.0.2_linux-x64_bin.tar.gz -C /opt/module
tar -zxvf /opt/software/hadoop-2.10.0.tar.gz -C /opt/module

# 配置JDK、Hadoop 环境变量
sudo vim /etc/profile
# JDK环境变量
# export JAVA_HOME=/opt/module/jdk-14.0.2
# export PATH=$PATH:$JAVA_HOME/bin

# Hadoop环境变量
# export HADOOP_HOME=/opt/module/hadoop-2.10.0
# export PATH=$PATH:$HADOOP_HOME/bin
# export PATH=$PATH:$HADOOP_HOME/sbin


# 重新读取配置
source /etc/profile
