修改opt/modules/hive-1.2.1/conf/目录下的配置文件
修改hive-env.sh文件（配置Hadoop环境变量和hive配置文件目录）
cd opt/modules/hive-1.2.1/conf/
mv hive-env.sh.template hive-env.sh
vi hive-env.sh

HADOOP_HOME=/opt/software/hadoop-2.6.0-cdh5.7.6 export HIVE_CONF_DIR=/opt/software/hive-3.1.1/conf

修改hive-log4j2.properties文件(修改日志目录和文件名)
mv hive-log4j2.properties.template hive-log4j2.properties
vi hive-log4j2.properties

property.hive.log.dir = /opt/software/hive-3.1.1/logs property.hive.log.file = hive.log

配置Hive的Metastore
cd /opt/software/hive-3.1.1/conf
cp hive-default.xml.template hive-site.xml
清空文件内容：:>hive-site.xml
vi hive-site.xml

将MySQL的JDBC驱动包放到hive的lib目录下
我的MySQL是5.7版本的，所以要下载8.0及以上的驱动
rz

cp mysql-connector-java-8.0.13.tar.gz ../software/hive-3.1.1/lib/

设置为全局变量（如果不想设置为全部变量此步骤可以忽略）
sudo vi /etc/profile

#HIVE_HOME export HIVE_HOME=/opt/software/hive-3.1.1 export PATH=$PATH:$HIVE_HOME/bin export CLASSPATH=$CLASSPATH:/opt/software/hadoop-2.6.0-cdh5.7.6/lib/*:. export CLASSPATH=$CLASSPATH:/opt/software/hive-3.1.1/lib/*:.

刷新环境变量：source /etc/profile

输入命令测试

hive服务启动脚本

cat start-hiveserver2.sh

cat start-metastore.sh

#!/bin/sh   HIVE_HOME=/opt/software/hive-3.1.1  ## 启动服务的时间 DATE_STR=`/bin/date '+%Y%m%d%H%M%S'`  # 日志文件名称(包含存储路径) HIVE_SERVER2_LOG=${HIVE_HOME}/logs/hivemetastore-${DATE_STR}.log  ## 启动服务 /usr/bin/nohup ${HIVE_HOME}/bin/hive --service metastore > ${HIVE_SERVER2_LOG} 2>&1 &
