首先这是要执行的一系列命令
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
rpm -Uvh http://repo.mysql.com//mysql57-community-release-el7-7.noarch.rpm
yum -y install mysql-community-server
systemctl start mysqld
systemctl enable mysqld
systemctl status mysqld
grep 'temporary password' /var/log/mysql.log(看临时密码）
mysql -uroot -p'Wqqi>mJPA3i='（登录进去）
set global validate_password_policy=LOW;
set global validate_password_length=4;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
grant all privileges on . to root@"%" identified by 'root' with grant option;
flush privileges;
然后就是下载安装hive
tar -zxvf apache-hive-3.1.3-bin.tar.gz -C /export/server/
去网上下载驱动mysql-connector-java-5.1.49.jar
把 jar 放到 Hive 的 lib 目录
cp mysql-connector-java-5.1.49.jar /export/server/hive/lib/
接下来
mv hive-env.sh.template hive-env.sh
其次便是配置文件hive-env.sh，$HIVE_HOME/conf/hive-site.xml（搜素即可）
配置完成后打开hdfs服务再去启动hive
