1. 下载
可以从http://hive.apache.org/downloads.html下载你想要的版本，在这我们使用的是2.1.0版本
2. 解压
把下载好的文件解压到~/opt目录下：
xiaosi@yoona:~$ tar -zxvf apache-hive-2.1.0-bin.tar.gz -C opt/
3. 配置
根据模板创建配置文件
xiaosi@yoona:~/opt/hive-2.1.0/conf$ cp hive-default.xml.template hive-site.xmlxiaosi@yoona:~/opt/hive-2.1.0/conf$ cp hive-log4j2.properties.template hive-log4j2.properties
修改配置文件
<property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://localhost:3306/hive_meta?createDatabaseIfNotExist=true</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.jdbc.Driver</value><description>Driver class name for a JDBC metastore</description></property><property><name>javax.jdo.option.ConnectionUserName</name><value>root</value><description>Username to use against metastore database</description></property><property><name>javax.jdo.option.ConnectionPassword</name><value>root</value><description>password to use against metastore database</description></property><property><name>hive.metastore.warehouse.dir</name><value>/user/hive/warehouse</value><description>location of default database for the warehouse</description></property>-
4. Hive元数据
创建存储Hive元数据的数据库，这里我们使用mysql存储：
mysql> create database hive_meta;Query OK, 1 row affected (0.00 sec)
5. 设置环境变量
在/etc/profile文件下添加如下配置：
# hive pathexport HIVE_HOME=/home/xiaosi/opt/hive-2.1.0export PATH=${HIVE_HOME}/bin:$PATH
6. 启动
运行bin/hive命令，即可启动：
xiaosi@yoona:~$ cd $HIVE_HOMExiaosi@yoona:~/opt/hive-2.1.0$ ./bin/hiveSLF4J: Class path contains multiple SLF4J bindings.SLF4J: Found binding in [jar:file:/home/xiaosi/opt/hive-2.1.0/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: Found binding in [jar:file:/home/xiaosi/opt/hadoop-2.7.3/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]Logging initialized using configuration in file:/home/xiaosi/opt/hive-2.1.0/conf/hive-log4j2.properties Async: trueHive-on-MR is deprecated in Hive 2 and may not be available in the future versions.
