编写自动安装Hadoop的shell脚本

完整流程: 大数据—Hadoop安装教程（二）

---

---

上传压缩包

在opt目录下创建连个目录install和soft
将压缩包上传到install目录下

---

编写shell脚本

创建目录来放shell脚本
[root@hadoop shellfile]# mkdir shellfile
修改hadoopautoinstall.sh的文件权限
chmod 777 ./hadoopautoinstall.sh

hadoopautoinstallsh_23">vim hadoopautoinstall.sh

#! /bin/bash
echo 'auto install hadoop begining....'

#global var
hadoop=true

if [ "$hadoop" = true ];then
  echo 'hadoop install set true'
  echo 'setup hadoop 3'
  tar -zxf /opt/install/hadoop-3.1.3.tar.gz -C /opt/soft/
  mv /opt/soft/hadoop-3.1.3 /opt/soft/hadoop313
