安装Mysql 数据库
数据库的安装顺序
(1)Mysql-server
(2)mysql-client
(3)启动mysql服务
(4)用root用户登录，以授权方式创建hive元数据库，和hive用户
grant all on hive.* to ‘hive‘@‘%‘ identified by ‘hive‘; 这个hive数据库，及其 用户和密码，是后面配置hive要用到的 ！！！
备注：Red Hat linux 下的mysql 安装 可参考 http://blog.itpub.net/28929558/viewspace-1192693/
2、/etc/profile
HADOOP_PREFIX=/opt/hadoop
JAVA_HOME=/opt/jdk18
ZOOKEEPER_HOME=/opt/zookeeper
HBASE_HOME=/opt/hbase
HIVE_HOME=/opt/hive
PATH=$PATH:$JAVA_HOME/bin:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:$HIVE_HOME/bin
3、修改$HIVE_HOME/conf 下面配置文件(将需要配置的两个模板，拷贝重命名)
点击(此处)折叠或打开
cp hive-env.sh.template hive-env.sh
cp hive-default.xml.template hive-site.xml
4、配置hive-env.sh 文件，指定 HADOOP_HOME
点击(此处)折叠或打开
# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/opt/hadoop
5、配置 hive-site.xml，指定MySQL数据库驱动、数据库名、用户名及密码，
修改的内容如下所示：
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</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>hive</value>
<description>username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
<description>password to use against metastore database</description>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
<description></description>
</property>
以上几个配置项，跟0.11.0版本没有区别，但是下面几个要注意配置下：
在hive下创建临时IO的tmp文件夹。然后将路径配置到下列参数中
<property>
<name>hive.querylog.location</name>
<value>/home/zhang/hive/iotmp</value>
<description>Location of Hive run time structured log file</description>
</property>
<property>
<name>hive.exec.local.scratchdir</name>
<value>/home/zhang/hive/iotmp</value>
<description>Local scratch space for Hive jobs</description>
</property>
<property>
<name>hive.downloaded.resources.dir</name>
<value>/home/zhang/hive/iotmp</value>
<description>Temporary local directory for added resources in the remote file system.</description>
</property>
备注如果不配置启动或操作hive时候会报错
载 mysql-connector-java-5.1.34-bin.jar 文件，并放到$HIVE_HOME/lib目录下 （到官网自行下载即可）
如果没有此jar包，启动hive会报如下错误：
Caused by: org.datanucleus.store.rdbms.connectionpool.DatastoreDriverNotFoundException: The specified datastore driver (\"com.mysql.jdbc.Driver\") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.

at org.datanucleus.store.rdbms.ConnectionFactoryImpl.generateDataSources(ConnectionFactoryImpl.java:238)

至此，部署完毕，可以启动，测试下：
看到如下结果，说明启动成功
[zhang@namenode ~]$ hive

创建表测试：如果这部分没有报错，那么去检查HDFS下面是否生成了相关文件
hive> create table test(t_id int,t_name string) row format delimited fields terminated by \‘|\‘ stored as textfile;
OK
Time taken: 1.586 seconds
hive> show tables;

hive> select * from test;
OK

检查HDFS是否生成相关文件：
[zhang@datanode01 ~]$ hdfs dfs -ls /
