step1 安装mysql

step2 在mysql数据库中创建数据库hive用来存储metastore数据，同时创建能够进入hive的用户

mysql> create database hive;
mysql> create user hadoop 'hadoop'@'localhost' identified by '123456';
mysql> grant all privileges on hive.* to 'hadoop'@'localhost' with grant option;
mysql> flush privileges;

step3 下载编译好的hive包：http://mirrors.cnnic.cn/apache/hive/stable/apache-hive-0.13.1-bin.tar.gz

step4 解压apache-hive-0.13.1-bin.tar.gz包 

tar -zxvf apache-hive-0.13.1-bin.tar.gz -C /opt/

step5 配置hive相关文件

a.配置hive/conf中的hive-site.xml 文件（默认的没有这个文件，我们复制hive-default.xml.template，然后改名为hive-site.xml. 把其中的配置信息替换成下面这些） 

<property>
 <name>hive.metastore.uris</name>
 <value></value>
 <description>此处value值为空，表示hive.metastore.local为true</description>
</property>
<property> 
 <name>javax.jdo.option.ConnectionURL</name> 
 <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value> 
</property> 
<property> 
 <name>javax.jdo.option.ConnectionDriverName</name>
 <value>com.mysql.jdbc.Driver</value> 
</property> 
<property> 
 <name>javax.jdo.option.ConnectionUserName</name> 
 <value>hadoop</value> 
</property> 
<property> 
 <name>javax.jdo.option.ConnectionPassword</name>
 <value>123456</value> 
</property>

b.把MySQL的JDBC驱动包复制到hive/lib目录下(如果没有lib目录自己建一个)。

step6.测试：进入到/opt/apache-hive-0.13.1-bin/bin/目录执行 hive进入hive然后执行show tables;查看结果如下：

# cd /opt/apache-hive-0.13.1-bin/bin
# ./hive
f14/08/09 20:09:50 WARN conf.hiveconf:DEPRECATED:hive.metastore.ds.retry.* no longer has any effect.use hive.hmshandler.retry.* instead

logging initialized using configuration in jar:file:/opt/apache-hive-0.13.1-bin/lib/hive-common-0.13.1.jar！/hive-log4j.properties
hive> show tables;
OK
Time taken: 1.61 seconds, Fetched:1 row(s)
hive>

如果不报错，表明基于独立元数据库的Hive已经安装成功了。
