1. 基础安装步骤
   a. tar开文件到指定的目录下面

tar -zxvf apache-hive-2.1.1-bin.tar.gz -C /usr/local/software/
b. 创建软连接

ln -s /usr/local/software/apache-hive-2.1.1-bin /usr/local/software/hive

[root@s102 /usr/local/software]#ls -al

c. 编辑/etc/profile文件

#最后一行
export HIVE_HOME=/usr/local/software/hive
export PATH=$PATH:$HIVE_HOME/bin
d. 让环境变量生效

source /etc/profile

e.修改配置文件 cp hive-default.xml.template hive-site.xml （只有这么一个配置文件）

先在pom.xml导入，然后在C:\sjfxwj\code location\maven_local_repository\mysql中下载

驱动的版本不用和mysql的版本一样

2. 登陆hive，进行数据验证
   $hive>create database mydb ; – 创建数据库
   $hive>use mydb ; – 使用库
   $hive>create table custs(id int , name string) ; – 建表
   $hive>desc custs ; – 查看表结构
   $hive>desc formatted custs ; – 查看格式化表结构
   $hive>insert into custs(id,name) values(1,‘tom’); – 插入数据，转成mr.
   $hive>select * from custs ; – 查询，没有mr
