引言
本文有博主手敲代码，可以直接复制！（怕水印挡住截图大家看不清）文章也有贴上传到虚拟机所需的资源，是免费下载的！！如果对正在阅读博客的你有帮助，可以动动小手帮我点个赞或者收藏！主页还有其他文章欢迎访问，你的关注将会是我更新的动力~谢谢！
一、数据库MySQL安装
（使用root账户）
1. 检查操作系统是否有MySQL安装残留
rpm -qa | grep -i mysql
rpm -qa | grep -i mariadb
2. 删除残留的MySQL安装（使用yum）
yum -y remove mariadb*
3. 安装MySQL依赖包、客户端和服务器
在我上传的资源可以免费下载
https://download.csdn.net/download/m0_67830223/89512921?spm=1001.2014.3001.5503
rpm -ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm
rpm -ivh MySQL-client-community-5.1.73-1.rhel5.x86_64.rpm
rpm -ivh MySQL-devel-community-5.1.73-1.rhel5.x86_64.rpm
4. MySQL登录账户root设置密码
密码值自定义，这里设为‘abc1234’
cd /usr/bin
mysqladmin -u root password 'abc1234'
5. 启动MySQL服务
systemctl start mysql.service //启动mysql
systemctl status mysql.service //查看状态
6. 登录MySQL，进入数据库操作提示符
mysql -u root -p
7. 授权Hive远程登录账户
grant all on *.* to 'ryx'@'%' identified by 'ryx123'; //“账户”和“密码”自定义
flush privileges; 
8. 创建Hive元数据数据库hive_1
可自命名，符合命名规则即可
create database hive_1;
二、Hive安装配置（使用hadoop用户）
1. 上传压缩包apache-hive-3.1.2-bin.tar.gz到hadoop01（或者其他虚拟机）
在本文最上方资源可以免费下载！！
2. 在安装目标文件夹内解压缩安装包
tar -zxvf apache-hive-3.1.0-bin.tar.gz
3. 编辑hive配置文件hive-site.xml
（路径在hive安装目录的conf下）
cp hive-default.xml.template hive-site.xml
vi hive-site.xml
第1步，先删除hive-site.xml中的大部分内容，删除后的内容如下图所示：
第2步：在<configuration>标签对中添加以下内容
注意填写的value值根据自己的数据库名、账号密码修改！！！

4. 解压并导入MySQL依赖包
在我上传的资源可以免费下载
https://download.csdn.net/download/m0_67830223/89512921?spm=1001.2014.3001.5503
tar -zxcf mysql-connector-java-5.1.27.tar.gz 
cd mysql-connector-java-5.1.27/ //进入解压的文件目录
sudo cp mysql-connector-java-5.1.27-bin.jar ~/apache-hive-3.1.0-bin/lib/ //将mysql的jar包复制到hive的lib目录下
5. 手动初始化元数据库（Hive2以上版本需要）
schematool -dbType mysql -initSchema
script completed
6. 配置hive启动的环境变量
export HIVE_HOME=/home/2130502441ryx/apache-hive-3.1.0-bin
export PATH=$HADOOP_HOME/sbin:$PATH:$HIVE_HOME/bin
7. 启动hive
hive
