【大数据】Hadoop在呼唤Hive（附一键部署Hive脚本）

CSDN话题挑战赛第2期
参赛话题：学习笔记

一、准备工作

1、下载Hive包

Hive下载地址
本文以apache-hive-3.1.2-bin.tar.gz作为部署，可以自身需要选择版本
Hive文档地址

2、下载mysql的rpm包

01_mysql-community-common-5.7.29-1.el7.x86_64.rpm
02_mysql-community-libs-5.7.29-1.el7.x86_64.rpm
03_mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm
04_mysql-community-client-5.7.29-1.el7.x86_64.rpm
05_mysql-community-server-5.7.29-1.el7.x86_64.rpm
mysql-connector-java-5.1.48.jar

3、下载Hive引擎tez包

tez-0.10.1-SNAPSHOT.tar.gz

4、将shell脚本放到/usr/bin下

给脚本赋权限

cd /usr/bin
chmod +x hive-install.sh

5、启动Hadoop集群

执行命令

 one 10

具体安装包可加公众号【纯码农（purecodefarmer）】输入“hive”即可获取下载链接
一键部署hadoop集群可参考【大数据】搭建Hadoop集群（附一键部署脚本）
备注：将下载的包放到hadoop集群主机的/opt/software/hive 目录下

二、Hive的搭建(脚本分解)

1、安装mysql

在安装mysql包时我们需要先删除自带的Mysql-libs
可使用命令查看是否有

rpm -qa | grep -i -E mysql\|mariadb

1、卸载原有的mysql

脚本内容

	echo "-------删除原有的mysql-------"
	systemctl stop mysqld
	service mysql stop 2>/dev/null
	service mysqld stop 2>/dev/null
	rpm -qa | grep -i mysql | xargs -n1 rpm -e --nodeps 2>/dev/null
	rpm -qa | grep -i mariadb | xargs -n1 rpm -e --nodeps 2>/dev/null
	rm -rf /var/lib/mysql
	rm -rf /usr/lib64/mysql
	rm -rf /etc/my.cnf
	rm -rf /usr/my.cnf
	rm -rf /var/log/mysqld.log

执行脚本命令

sh hive-install.sh 1

2、安装mysql驱动包

脚本内容

	cd /opt/software/hive
	echo "-------安装mysql依赖-------"
	rpm -ivh 01_mysql-community-common-5.7.29-1.el7.x86_64.rpm
	rpm -ivh 02_mysql-community-libs-5.7.29-1.el7.x86_64.rpm
	rpm -ivh 03_mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm
	
	echo "-------安装mysql-client-------"
	rpm -ivh 04_mysql-community-client-5.7.29-1.el7.x86_64.rpm
	
	echo "-------安装mysql-server-------"
	rpm -ivh 05_mysql-community-server-5.7.29-1.el7.x86_64.rpm
	
	echo "-------启动mysql-------"
	systemctl start mysqld
	
	pass=`cat /var/log/mysqld.log | grep password`
	pass1=`echo ${pass#*localhost: }`
	echo "-------mysql 初始密码-------" $pass1
	
	echo "-------登录mysql-------"
	mysql -uroot -p$pass1

执行脚本命令

sh hive-install.sh 1

3、修改mysql的默认密码

# 设置复杂密码
mysql> set password=password("Jimmy!1@2#3");
# 修改密码策略
mysql> set global validate_password_length=4;
mysql> set global validate_password_policy=0;
# 设置简单密码
mysql> set password=password("1qazxsw2");
# 进入mysql库修改Host
mysql> use mysql;
mysql> update user set host="%" where user="root";
# 刷新并退出
mysql> flush privileges;
mysql> quit;

2、安装hive

安装完Mysql驱动后安装Hive的安装包

1、安装Hive并配置环境变量

脚本内容

	echo "-------解压Hive的安装包-------"
	mkdir /opt/module/hive312
	tar -zxvf /opt/software/hive/apache-hive-3.1.2-bin.tar.gz -C /opt/module/hive312
	echo "-------重命名Hive解压包-------"
	mv /opt/module/apache-hive-3.1.2-bin/ /opt/module/hive312
	
	echo "-------配置Hive的环境变量-------"
	echo "" >> /etc/profile.d/my_env.sh
	echo "#Hive environment" >> /etc/profile.d/my_env.sh
	echo "export HIVE_HOME=/opt/module/hive312" >> /etc/profile.d/my_env.sh
	echo "export PATH=\$PATH:\${HIVE_HOME}/bin" >> /etc/profile.d/my_env.sh

    echo "-------解决日志Jar包冲突-------"
	mv /opt/module/hive312/lib/log4j-slf4j-impl-2.10.0.jar /opt/module/hive312/lib/log4j-slf4j-impl-2.10.0.bak
	
	echo "-------拷贝Mysql驱动放到Hive下-------"
	cp /opt/software/hive/mysql-connector-java-5.1.48.jar /opt/module/hive312/lib

执行脚本命令

sh hive-install.sh 2

备注：配置了环境变量重新刷新后进入，不然环境变量不生效
