linux中hive安装和部署详解

一.前期准备

1.1 hadoop

版本：Hadoop 2.6.5

安装：http://blog.csdn.net/a123demi/article/details/70652959

1.2 mysql

版本：5.6.33 MySQL Community Server (GPL)

1.3 mysql驱动包

版本：mysql-connector-java-5.1.40-bin.jar

1.4 hive安装包

官网下载：apache-hive-2.1.1-bin.tar.gz

二.hive安装

2.1 hive部署

#定位
cd /opt/software
#解压
tar -zxvf apache-hive-2.1.1-bin.tar.gz 
#复制hive解压到/usr/local/hive
cp -r apache-hive-2.1.1-bin /usr/local/hive

2.2 mysql驱动包导入

把1.3中的mysql驱动包放置到$HIVE_HOME\lib目录

三.hadoop配置

3.1 启动dfs+yarn

#定位
cd /usr/local/hadoop
#启动dfs+yarn
sbin/start-all.sh

3.2 创建HDFS目录并赋予权限

hdfs dfs -mkdir -p /usr/hive/warehouse
hdfs dfs -mkdir -p /usr/hive/tmp
hdfs dfs -mkdir -p /usr/hive/log
hdfs dfs -chmod g+w /usr/hive/warehouse
hdfs dfs -chmod g+w /usr/hive/tmp
hdfs dfs -chmod g+w /usr/hive/log

四.hive配置

4.1 配置环境变量

vi /etc/profile
--------------------------------------------
#hive
export HIVE_HOME=/usr/local/hive
#path
export PATH=$PATH:$HIVE_HOME/bin
--------------------------------------------
重新编译profile
source /etc/profile

4.2 hive-env.sh配置

#定位
cd /usr/local/hive/conf
#生成hive-env.sh文件
cp -r hive-env.sh.template hive-env.sh
#配置
vi hive-env.sh
--------------------------------------------
# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
# export HIVE_AUX_JARS_PATH=

export JAVA_HOME=/usr/local/jdk
export HADOOP_HOME=/usr/local/hadoop
export HIVE_HOME=/usr/local/hive
# HADOOP_HOME=${bin}/../../hadoop

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=$HIVE_HOME/conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=/usr/local/hive/lib/*

4.3 hive-site.xml配置

#生成hive-site.xml文件
cp -r hive-default.xml.template hive-site.xml 
#配置
vi hive-site.xml
--------------------------------------------

  
  
  
  
  
    hive.exec.scratchdir
    /usr/hive/tmp
    HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/ is created, with ${hive.scratch.dir.permission}.
  
  
    hive.metastore.warehouse.dir
    /usr/hive/warehouse
    location of default database for the warehouse
  

    hive.querylog.location
    /usr/hive/log
    Location of Hive run time structured log file
  
 
    javax.jdo.option.ConnectionURL
    jdbc:mysql://192.168.32.128:3306/hive?createDatabaseIfNotExist=true&characterEncoding=UTF-8&useSSL=false
  
  
    javax.jdo.option.ConnectionDriverName
    com.mysql.jdbc.Driver
  
  
    javax.jdo.option.ConnectionUserName
    root
  
  
    javax.jdo.option.ConnectionPassword
    root
  

4.4 注意

本文mysql用户使用的是root用户，生产环境可以自建一个用户，

五.测试实现

5.1schematool 命令来执行初始化操作

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

5.2 Hive客户端启动

#命令
hive

hive操作的命令基本与mysql一致。
