1.安装mysql（参考文章：centos7.8安装Mysql8.4-CSDN博客）

2.将mysql驱动拷贝到/opt/module/hive/lib目录下 （直接windows通过finalShell上传）

3./opt/module/hive/conf目录下新建hive-site.xml文件，进行配置

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://slave01:3306/metastore?useSSL=false</value>
    <description>
      JDBC connect string for a JDBC metastore.
      To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
      For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.
    </description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionDriverName</name>
    <value>com.mysql.cj.jdbc.Driver</value>
    <description>Driver class name for a JDBC metastore</description>
  </property>
<property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>root</value>
       <description>用户名</description>
  </property>
  <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>Yt123456.</value>
       <description>密码</description>
  </property>
 <!--hive默认在HDFS上的目录-->
  <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/user/hive/warehouse</value>
  </property>

</configuration>
 

4.在Mysql中创建数据库metastore

5.初始化元数据库(mysql)

schematool -dbType mysql -initSchema -verbose

6.测试
