我是靠谱客的博主傲娇小刺猬，这篇文章主要介绍Hive安装部署，现在分享给大家，希望可以做个参考。

1.首先安装jdk和Hadoop环境，参考Hadoop单机安装_letterss的博客-CSDN博客

2.下载Hive安装包，下载地址：https://www.apache.org/dyn/closer.cgi/hive/

将下载的安装包上传到/data/hive目录，并解压

tar -zxvf apache-hive-2.3.9-bin.tar.gz

配置hive环境

vi /etc/profile

复制代码

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-1.el7_9.x86_64
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export HADOOP_HOME=/data/hadoop/hadoop-2.10.1
export HIVE_HOME=/data/hive/apache-hive-2.3.9-bin
export PATH=.:$JAVA_HOME/bin:$HADOOP_HOME:$HIVE_HOME/bin:$PATH

更新环境变量

source /etc/profile

配置完成可输入hive --version 查看版本

修改hive配置文件,进去 /data/hive/apache-hive-2.3.9-bin/conf 路径下,创建hive-site.xml文件

vim hive-site.xml

复制代码

将MySQL的驱动mysql-connector-java-5.1.40-bin.jar添加到hive安装目录的lib下

元数据库初始化,切换到hive的bin目录下执行

./schematool -dbType mysql -initSchema

hive的启动,运行hive之前要确保hadoop集群启动和MySQL服务启动正常开启的情况下

由于配置过环境变量，可以直接在命令行中输入hive 本地启动命令 hive

测试hive,输入以下建表语句

show databases;
create database test_work; //新建一个测试库
use test_work;
create table test(
id int
,name string
);
insert into table test values(1,"wangsheng");

以上正常执行，表明hive已经安装和配置完成。可去hdfs图形界面上查看建的表，访问hadoopIP:50070
