1、java

需要安装java

rz
tar -zxvf jdk-8u381-linux-x64.tar.gz -C /
ln -s /jdk1.8.0_381/ /jdk
# rm jdk-8u381-linux-x64.tar.gzvim /etc/profile
export JAVA_HOME=/jdk
export PATH=$PATH:$JAVA_HOME/bin
# source /etc/profile
ln -s /jdk/bin/java /usr/bin/java

hadoop可以选择清华源或者官网下载官网

rz	# 上传hadoop包到机器
tar -zxvf hadoop-3.3.6.tar.gz -C /	# 解压到对应目录
ln -s /hadoop-3.3.6/ /hadoop	# 创建软连接
# rm -rf hadoop-3.3.6.tar.gz 删除包

[root@localhost hadoop]# ll
