2.1.3 删除MySQL相应文件
2.2 安装MySQL
2.2.1 下载MySQL的yum源
[[email protected] yao]# wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
2.2.2 查看下载源中包含的rpm包
[[email protected] yao]# rpm -qpl mysql57-community-release-el7-7.noarch.rpm
2.2.3 安装rpm包
[[email protected] yao]# rpm -ivh mysql57-community-release-el7-7.noarch.rpm
2.2.4 安装MySQL
[[email protected] yao]# yum install -y mysql-community-server
2.2.5 获取临时密码
- 启动mysqld服务
[[email protected] log]# /bin/systemctl start mysqld.service
- 查找初始密码
[[email protected] log]# grep "password" /var/log/mysqld.log

2. 设置安全级别
mysql> set global validate_password_policy=0;
- 设置密码长度
mysql> set global validate_password_length=4;
- 设置密码
mysql> set password=password('1234');
2.3 配置MySQL
2.3.1 创建数据库
mysql> create database hive;
2.3.2 创建hadoop用户
mysql> grant all on *.* to [email protected]'%' identified by "hadoop";
mysql> grant all on *.* to [email protected]'localhost' identified by 'hadoop';
mysql> grant all on *.* to [email protected]'master' identified by 'hadoop';
mysql> flush privileges;
3 安装Hive
切换到普通用户下
3.1 解压Hive安装包
[[email protected] ~]$ tar -zxvf apache-hive-1.2.1-bin.tar.gz
3.2 配置参数文件
在conf目录下创建新文件hive-site.xml
[[email protected] ~]$ cd apache-hive-1.2.1-bin/conf/
[[email protected] conf]$ vi hive-site.xml
添加内容：
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
