前提：
下载安装压缩包：apache-hive-2.1.0-bin.tar.gz
已经安装了Mysql和Hadoop
解压缩安装包：apache-hive-2.1.0-bin.tar.gz
设置 Hive环境变量
export JAVA_HOME=/home/liguodong/install/jdk
export HADOOP_HOME=/home/liguodong/install/hadoop
export HIVE_HOME=/home/liguodong/install/hive
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$PATH"在 Hive 中创建表之前，需要在HDFS上创建hive-site.xml文件配置的目录/usr/liguodong/tmp 和 /user/hive/warehouse ( 属性项 hive.metastore.warehouse.dir 的默认值) ，并给它们赋写权限。
hdfs dfs -mkdir -p /usr/liguodong/tmp
hdfs dfs -mkdir -p /usr/hive/warehouse
//用户组加写权限
hdfs dfs -chmod g+w /usr/liguodong/tmp
hdfs dfs -chmod g+w /usr/hive/warehouse使环境变量生效:
source .bashrc配置Hive
配置文件重命名
cp hive-env.sh.template hive-env.sh
cp hive-default.xml.template hive-site.xml
cp hive-log4j2.properties.template hive-log4j2.properties
cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties修改hive-env.sh
因为 Hive 使用了 Hadoop, 需要在 hive-env.sh 文件中指定 Hadoop 安装路径：
export JAVA_HOME=/home/liguodong/install/jdk
export HADOOP_HOME=/home/liguodong/install/hadoop
export HIVE_HOME=/home/liguodong/install/hive
export HIVE_CONF_DIR=/home/liguodong/install/hive/conf修改hive-site.xml
替换hive-site.xml文件中的${system:java.io.tmpdir} 和${system:user.name}
在命令行运行 hive 命令时必须保证 HDFS 已经启动。可以使用 start-dfs.sh 来启动 HDFS。
从 Hive 2.1 版本开始, 我们需要先运行 schematool 命令来执行初始化操作。
schematool -dbType mysql -initSchema进入hive命令行
hivebeeline
./bin/hive --service hiveserver2 &
bin/beeline
