Hadoop安装配置Mysql数据库的步骤教程

搭建mysql

下载mysql 的安装包道liunx上。

解压 tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

在上安装mysql：

卸载原先liunx上自带的mysql

yum remove mysql-libs

rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm

客户端

rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-devel-5.7.19-1.el7.x86_64.rpm (可选)

启动mysql：service mysqld start

或者：systemctl start mysqld.service

查看root用户的密码：cat /var/log/mysqld.log | grep password

登录后修改密码：alter user 'root'@'localhost' identified by 'welcome_1';

mysql数据库的配置：

创建一个新的数据库：create database hive;

创建一个新的用户：

create user 'hiveowner'@'%' identified by 'welcome_1';

给该用户授权

grant all on hive.* to 'hiveowner'@'%';

grant all on hive.* to 'hiveowner'@'localhost' identified by 'welcome_1'; 完毕。
