官网下载hive，解压文件。
安装mysql:

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server

启动mysql:

systemctl start mysqld.service

查看是否启动成功:

systemctl status mysqld.service

查看生成的密码:

grep "password" /var/log/mysqld.log

用刚刚的密码登录mysql:

mysql -u root -p

关闭密码长度限制:

set global validate_password_policy=0;

set global validate_password_length=1;

修改密码:

ALTER USER 'root'@'localhost' IDENTIFIED BY '自己想设置的密码'; 

顺便打开远程访问:GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
hive配置:

cp hive-default.xml.template hive-site.xml

修改 hive-site.xml的四个参数:

 <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>登录用户名</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>mysql密码</value>
    </property>
   <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://地址:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
