前言

本文介绍了如何使用Shell脚本一键安装Sqoop。Sqoop是一个用于在Apache Hadoop和结构化数据存储（如关系数据库）之间传输数据的工具。通过使用Sqoop，您可以方便地将数据从关系数据库导入到Hadoop集群中进行分析，并将结果数据导出回关系数据库。

在本文中，我们将提供一个Shell脚本，该脚本将自动下载、安装和配置Sqoop。您只需按照步骤执行脚本，即可完成Sqoop的安装和配置过程。

一、使用shell脚本一键安装

1. 复制脚本

首先，将以下脚本内容复制并保存为/tmp/install_sqoop.sh文件。

#!/bin/bashinstallDir="/opt/module/sqoop"
sqoop_version="1.4.6"
mysql_connector_version="5.1.37"if [ -z "$(command -v wget)" ]; thensudo yum install -y wgetecho "wget安装完成"
fi
if [ -z "$JAVA_HOME" ]; thenecho "JAVA_HOME未设置，请安装jdk1.8，设置Java环境变量再来执行此脚本"exit 1
fi
if [ ! -d "${installDir}" ]; thensudo mkdir -p "${installDir}"if [ $? -eq 0 ]; thenecho "安装目录${installDir}已创建"elseecho "请确保您有足够的权限来创建目录，请增加权限后再次执行"exit 1fi
fi

fi
