Hadoop单机模式部署操作步骤
1、创建用户
sudo useradd -m hadoop -s /bin/bash
sudo passwd hadoop
sudo adduser hadoop sudo
2、注销当前用户并使用hadoop用户登陆
sudo su - hadoop
3、更新资源库

cat id_rsa.pub>>authorized_keys
6、安装Java环境
sudo apt-get install openjdk-8-jre openjdk-8-jdk
cd
vim ~/.bashrc
7、在文件第一行添加
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HADOOP_OPTS=“-Djava.library.path=${HADOOP_HOME}/lib/native”
export JAVA_LIBRARY_PATH=/usr/local/hadoop/lib/native
8、使变量生效
source ~/.bashrc
9、安装hadoop 2
cd /usr/local
sudo tar -zxvf ./hadoop-2.10.1.tar.gz
sudo mv ./hadoop-2.10.1/ ./hadoop
sudo chown -R hadoop ./hadoop
