2、安装hive

#解压缩
tar -zxvf /usr/local/soft/apache-hive-3.1.1-bin.tar.gz -C /usr/local/

#修改目录名称
mv /usr/local/apache-hive-3.1.1-bin/ /usr/local/apache-hive-3.1.1

vim /etc/profile

#增加HIVE环境变量内容
export HIVE_HOME=/usr/local/apache-hive-3.1.1
export PATH=$PATH:$HIVE_HOME/bin
export CLASSPATH=$CLASSPATH:$HIVE_HOME/bin

使环境变量生效：source /etc/profile

vim /usr/local/apache-hive-3.1.1/conf/hive-env.sh

#增加内容
export HADOOP_HOME=/usr/local/hadoop-3.1.1
export HIVE_CONF_DIR=/usr/local/apache-hive-3.1.1/conf

vim /usr/local/apache-hive-3.1.1/conf/hive-site.xml

#将下载好的 mysql 驱动拷贝到hive的lib目录中
cp /usr/local/soft/mysql-connector-java-8.0.12.jar /usr/local/apache-hive-3.1.1/lib/

#在 mysql 服务器中新建空数据库 hadoop_hive_meta，跟 hive-site.xml 中配置的数据库名称一致
#首次启动初始化schema
schematool -dbType mysql -initSchema

3、验证
