执行下载

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
如果提示-bash: wget: 未找到命令，请先执行 yum install wget 安装 wget

4.添加 MySQL Yum Repository

添加 MySQL Yum Repository 到你的系统 repository 列表中，执行
yum localinstall mysql-community-release-el7-5.noarch.rpm

6.开始yum安装mysql

yum install mysql-community-server

7.开启

systemctl start mysqld
systemctl status mysqld #查看状态

9.创建hive需要的数据库

在mysql上创建hive元数据库，并对hive进行授权

create database if not exists hive_metadata;grant all privileges on hive_metadata.* to 'hive'@'%' identified by 'hive';grant all privileges on hive_metadata.* to 'hive'@'localhost' identified by 'hive';grant all privileges on hive_metadata.* to 'hive'@'s201' identified by 'hive';flush privileges;use hive_metadata;
