cd /opt/software/
进入软件目录
tar -zxvf hadoop-3.1.3.tar.gz -C /opt/module/
解压缩，这个比较久，内容比较多
将Hadoop添加到环境变量进入到
[root@hadoop102 module]# cd hadoop-3.1.3/
[root@hadoop102 hadoop-3.1.3]# pwd
/opt/module/hadoop-3.1.3
sudo vim /etc/profile.d/my_env.sh
修改环境变量
#HADOOP_HOME export HADOOP_HOME=/opt/module/hadoop-3.1.3 export PATH=$PATH:$HADOOP_HOME/bin export PATH=$PATH:$HADOOP_HOME/sbin
加入上面这段内容
让修改的文件生效：
source /etc/profile
测试是否安装成功 hadoop version
