# Download and install mysql
 yum  install mysql mysql mysql- Server- devel 

# start mysql service 
cd / etc / 
init.d / mysqld Start 

#mysql connection and log

2, the configuration hive

#1.上传安装包并解压
#然后，cd /export/servers/hive-1.2.1/conf

#2.修改hive-env.sh
# Set HADOOP_HOME to point to a specific hadoop install directory
 HADOOP_HOME=/export/servers/hadoop-2.6.0-cdh5.14.0

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/export/servers/hive-1.2.1/conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=/export/servers/hive-1.2.1/lib


#3.新建hive-site.xml文件
<configuration>
<property>  
  <name>javax.jdo.option.ConnectionURL</name>  
  <value>jdbc:mysql://node01:3306/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>root</value>
  <description>username to use against metastore database</description>  
</property>  
<property>  
  <name>javax.jdo.option.ConnectionPassword</name>  
  <value>password</value>  
  <description>password to use against metastore database</description>  
</property>
 <property> 
      <name>hive.server2.thrift.port</name> 
      <value>10000</value> 
 </property>
 <property>
       <name>hive.server2.thrift.bind.host</name>
       <value> amdha01 </ value> 
 </ Property> 
</ Configuration> 

# . 4 . Upload mysql jar package to connect the drive / Export / Servers / hive- 1.2 . . 1 / lib directory 
# 5 . hive system environment variable configuration 
Vim / etc / Profile 
Export HIVE_HOME = / Export / Servers / hive- 1.2 . . 1 
Export the PATH =: $ HIVE_HOME / bin: $ the PATH

3, hive remote service

#1.将node01上的hive安装包分发到node02、node03上，命令如下：
cd /export/servers
scp -r hive-1.2.1 node02:$PWD
scp -r hive-1.2.1 node03:$PWD

#2.在node01上启动hadoop集群
#3.在node01上启动hiveserver2服务,然后克隆当前会话，jps，查看一下当前进程
cd /export/servers/hive-1.2.1/bin
hiveserver2

#4.在node02上使用beeline远程连接至hive服务端
cd /export/servers/hive-1.2.1
bin/beeline

#5.输入远程连接协议，连接到指定hive服务的主机名和端口(默认10000)
!connect jdbc:hive2://node01:10000

#6.输入连接hive服务器的用户名和密码
